Disposable paper cups comprise typical single-use plastic items, as they are lined internally with a thin plastic coating for waterproofing. They are consumed at a staggering rate worldwide, with the UK alone consuming around 7 million cups daily, thus annually producing around 30,000 tonnes of paper cup waste. Contrary to popular belief, less than 1 in 400 paper cups is currently recycled in the UK, which is in stark contrast to the waste hierarchy and the European Commission's ambitious Circular Economy Action Plan. Paper cups typically end up in landfill sites or even improperly disposed of, contributing to (micro)plastic waste and potentially polluting the world's oceans. The implications of the latter are not fully known yet and cannot be quantified by existing life cycle impact assessment methods. By employing the life cycle assessment methodology, UK's annual carbon footprint from paper cup consumption was found to be 75 kt of carbon dioxide equivalents, which is similar to that of manufacturing 11,500 mid-size passenger cars. Globally, their environmental footprint was found to be comparable to that of some 1.5 M average European inhabitants, indicating the nature and extent of the single-use plastics problem, which paper cups are just a typical example of. Paper cup recycling could reduce this environmental footprint by up to 40%, whereas switching to reusable cups appears to be more environmentally sustainable, achieving a threefold reduction in carbon emissions, which at global scale is more than twice Malta's annual carbon footprint. Results indicate that consumerism along with small daily choices, such as using reusable cups or bags instead of their disposable counterparts, could play a huge role in climate change. At policy level, no concrete measures to curb the superfluous consumption of paper cups, as well as of other single-use plastic items that are becoming increasingly ubiquitous, have materialised. Furthermore, it appears that decision- and policy-makers tend to step in to curtail wasteful and polluting practices only when environmental problems have started to generate widespread concern, instead of undertaking preventative policy measures. Image 1 • The environmental sustainability of disposable paper cups was examined. • 75 kt CO 2eq are emitted annually in the UK and 7.5 Mt CO 2eq globally. • Switching to reusable cups axes carbon emissions by threefold. • Robust LCIA methods should be introduced to account for (micro)plastic pollution. • Existing policy on single use plastics appears to be too little too late.

This paper explores the relationship between people's feelings about dirt, and an apparent reduction in the lifetime of vacuum cleaners. The short life-spans of vacuum cleaners is a significant environmental issue. In addition to the waste generated, they have an impact on climate change: vacuum cleaners account for the second largest embodied greenhouse gas emissions of electrical goods in the UK after televisions, largely because of their high sales volumes. Drawing from qualitative and quantitative research undertaken for the UK Department for Environment, Food & Rural Affairs (Defra), the paper demonstrates that one motivation for vacuum cleaner replacement is the increased enjoyment from dirt removal that a new vacuum cleaner may provide. The paper also shows that premature disposal can occur once a product becomes dirty and visually damaged, and whilst functional, is perceived to be less effective. Solutions to premature disposal were explored through the co-creation of design concepts and design features were tested via an online survey. Vacuum cleaner users were clustered into four cleaner types; Spartan, Minimal, Caring and Manic. Overall, respondents reported that improving the ease of maintaining vacuum cleaners would be the most effective way to help them to increase their vacuum cleaner's longevity. Across all cleaner types maintenance levels were low, although Caring and Manic cleaners were significantly more likely to undertake such tasks. Motivations for disposal were similar across cleaner types and we found no evidence that Caring and Manic cleaners disposed of their machines earlier because they were 'worn out.' We discovered that Caring and Manic cleaners spend the most on their vacuum cleaners, vacuum more often and are the most likely to replace their machine after the shortest period. Those willing to do 'a lot more' to help the environment were significantly more likely to want to 'keep the floors in my home spotlessly clean' and significantly more likely to indicate that they preferred their vacuum cleaner to look new. Consequently, the paper proposes that design interventions to increase vacuum longevity should be targeted toward Caring and Manic cleaners and concludes with key design recommendations for these two cleaner types.

The UK is facing tremendous challenges in tackling food waste diversion from landfill. Whilst much effort has been made to prevent food waste, there is still a lack of attention and strategic approach in dealing with resource recovery and valorisation of food waste. This paper presents a systematic framework for sustainable organic waste management and valorisation in the UK through (i) review of current policy framework; (ii) analysis of resource recovery potential from food waste at national, community and organisational levels; (iii) proposition of alternative waste management strategies; and (iv) examination of challenges and opportunities with respect to economic, environment and social dimensions of sustainability of waste management strategies. The paper explores valorisation of source-segregated food waste and mixed waste from the supermarket and households into electricity and transportation fuels, through partially and completely decentralised configurations using anaerobic digestion and gasification technologies. This study demonstrates a potential for reducing the cost of electricity and greenhouse gas emissions of one supermarket store by 12% when adopting partially decentralised food waste anaerobic digestion strategy, and full substitution of fossil fuel based electricity with net surplus renewable electricity generation through complete decentralisation of mixed waste gasification. Therefore, a more integrated, circular and advanced technological approach in waste management should be undertaken as it can lead to a wider range of socio-economic and environmental advantages to the local community, highly essential in the UK. Image 1 • Valorisation of waste closer to the source promotes resource circularity. • A synergistic approach is robust in addressing challenges in waste management. • Technology and configuration determine the viability of valorisation strategies. • Decentralised waste management enhances community participation. • A supportive fiscal incentive scheme promotes uptake of waste valorisation.

Many higher education institutions have started to develop academic curricula, research capacity and outreach activities related to circular economy. However, little is known yet on how to apply circular economy thinking to sustainable campus management. In an attempt to address this gap, this paper proposes a methodological framework and guidance to help universities develop a circular economy strategy aimed at improving resource efficiency and environmental sustainability of their campus operations. The approach is compatible with sustainability management frameworks as it follows the well-known iterative process of planning, doing, checking and improving. The framework involves three main steps: analysis of current situation with respect to circular economy within the organisation; stakeholder engagement to get a buy-in and inform the development of a circular economy strategy; and implementation of the strategy following the guidelines provided within the framework. Application of the framework is illustrated through a case of the University of Manchester, demonstrating how circular economy principles can be used to benchmark existing sustainability policies and action plans. The paper also shows how engaging key stakeholders can be used to identify challenges and opportunities for embedding circular economy thinking into the university's sustainability management systems. The proposed framework and the guidelines for implementation of circular economy thinking are generic and can be applied by any institution across the higher education sector. Image 1 • There is a lack of knowledge on how to implement circular economy in universities. • A simple but powerful framework is proposed to guide institutions in that process. • Application of the framework is illustrated through a real case of a large UK university. • Challenges and opportunities for CE are discussed based on stakeholder interviews. • Guidelines are provided for the development and implementation of a CE strategy.

Abstract Progressing towards sustainable development remains a key global challenge. And yet, the various interpretations of the concept of sustainable development and the questions it raises about economic growth make its implementation difficult. Higher education institutions may help to overcome these difficulties by developing new processes of change. However, to achieve this they need to integrate sustainable development in all their areas of activity. The aim of this paper was to develop new insights into organisational change processes in universities relating to sustainable development. Contributing to this aim, this paper reports on a case study of United Kingdom higher education drawing on findings and conclusions from a survey of their policy frameworks relating to sustainable development. The method comprised a critical policy analysis in order to identify, differentiate and categorise stakeholder interactions. The data generated comprised the range of higher education stakeholders and the network of interactions that they formed. Theoretical insights from social network analysis, stakeholder theory and the normative business model were used to find opportunities to address the difficulties in the implementation of sustainable development. Results suggested that the existing networks identified in the policy frameworks may not support the effective integration of sustainable development in higher education. Low-density of the national networks; the lack of a clear governance vocabulary for national policy frameworks; and the lack of explicit funding flows between organisations all pose problems for organisational change towards sustainable development in higher education. Highlights • The paper develops insights in organisational change at universities in sustainable development. • Critical policy analysis identifies, differentiates and categorises stakeholder interactions. • Social network analysis, stakeholder theory, Normative Business Model inform interpretation. • Density, governance and funding of policy networks could aid change at universities.

In the process of implementing circular economy within the built environment, quantifying progress and performance towards this effort has posed a substantial challenge. In response, this paper reviews the current state of building-specific circularity indicators, creates a taxonomy, and integrates them within the Royal Institute of British Architects (RIBA) Plan of Work, a commonly employed framework within the UK's built environment. Through a systematic literature review considering both academic and grey literature, 32 building circularity indicators, developed by academia, consulting agencies, and governments, are identified. The first contribution of this study is the creation of a taxonomy of building circularity indicators, which classifies the identified indicators into 8 categories, such as basic characteristics of indicators, circularity level, and sustainability pillars. The second contribution of this study is the alignment of circularity within the stages of Plan of Work framework. It is revealed that the framework does not currently incorporate circularity, resulting in the proposal of a new Stage 8: End of Life to encompass demolition, disassembly, and deconstruction activities. Alignment of the taxonomy to Plan of Work framework provides a guide in utilization of building circularity indicators throughout the process of designing, constructing and operating building projects. • Building-specific circularity indicators are reviewed for the built environment. • A taxonomy of 32 building circularity indicators is created across eight categories. • A new Stage 8: End of Life is proposed for RIBA framework to enhance circularity. • The circularity indicators are integrated with the RIBA Plan of Work framework. • A traffic light approach is employed to guide the use of circularity indicators.

Carbon capture usage and storage (CCUS) is emerging as an important solution in delivering deep emissions reductions in energy-intensive industries, enabling hydrogen production, and possibly directly capturing existing carbon dioxide (CO 2) from the atmosphere. The potential for associated new industry activity – for example in CO 2 Transport and Storage (T&S) – could also be important in transitioning economies with legacy investment in oil and gas extraction. This paper addresses the question of how introducing a nascent T&S industry may impact the wider UK economy in the presence of persisting national labour supply constraints. It does so by refining a multi-sector economy-wide computable general equilibrium (CGE) model of the UK to run scenarios focussed on the emergence of a nascent sector, involving identification of benchmark activity – here, the existing oil and gas industry – where that nascent sector is not currently represented in national accounting data. Crucially, the CGE model embeds a theoretically and empirically tested wage bargaining function to consider how cost and price pressures triggered will condition dynamic outcomes for producers, consumers and government budgets. Results suggest that emergence of a new T&S industry is likely to deliver sustained net gains in UK employment and GDP. However, maximising T&S-linked jobs gains while minimising displacement of employment and price pressures elsewhere in the economy requires policy action to alleviate labour supply and skills constraints. This reinforces policy and industry recommendations around the need for net zero workforce planning and attention to the potential fiscal implications of taking action, or not/in different timeframes. • Introducing a new CO 2 Transport and Storage industry could boost the UK economy. • Wage responses in a supply constrained labour market substantially condition outcomes. • Wage-cost driven price impacts affect all producers, consumers and government budgets. • Mitigating wage bargaining pressure requires policy action on workforce planning. • Findings reinforce the need for economy-wide and fiscal analysis of net zero actions.

Transport-related activities represented 34% of the total carbon emissions in the UK in 2022 and heavy-duty vehicles (HGVs) accounted for one-fifth of the road transport greenhouse gas (GHG) emissions. Currently, battery electric vehicles (BEVs) and hydrogen fuel cell electric vehicles (FCEVs) are considered as suitable replacements for diesel fleets. However, these technologies continue to face techno-economic barriers, creating uncertainty for fleet operators wanting to transition away from diesel-powered internal combustion engine vehicles (ICEVs). This paper assesses the performance and cost competitiveness of BEV and FCEV powertrain solutions in the hard-to-abate HGV sector. The study evaluates the impact of battery degradation and a carbon tax on the cost of owning the vehicles. An integrated total cost of ownership (TCO) model, which includes these factors for the first time, is developed to study a large retailer's HGV fleet operating in the UK. The modelling framework compares the capital expenditures (CAPEX) and operating expenses (OPEX) of alternative technologies against ICEVs. The TCO of BEVs and FCEVs are 11% to 33% and 37% to 78% higher than ICEVs; respectively. Despite these differences, by adopting a longer lifetime for the vehicle it can effectively narrow the cost gap. Alternatively, cost parity with ICEVs could be achieved if BEV battery cost reduces by 56% or if FCEV fuel cell cost reduces by 60%. Besides, the pivot point for hydrogen price is determined at £2.5 per kg. The findings suggest that BEV is closer to market as its TCO value is becoming competitive, whereas FCEV provides a more viable solution than BEV for long-haul applications due to shorter refuelling time and lower load capacity penalties. Furthermore, degradation of performance in lithium-ion batteries is found to have a minor impact on TCO if battery replacement is not required. However, critical component replacement and warranty can influence commercial viability. Given the high costs, we propose financial incentives and vehicle tax reforms to reduce costs of critical components that will encourage the roll-out of zero emission HGVs. • TCO model employs real-world fleet data to compare HGV powertrain technologies. • Maximising vehicle lifetime is key to reduce the TCO gap and get closer to parity. • BEVs have a TCO 11%–33% higher than ICEVs. • FCEVs have a TCO 37%–78% higher than ICEVs. • Degradation in lithium-ion batteries is found to have a minor impact on TCO value.

International headlines over the last few years have been dominated by extreme weather events, and floods have been amongst the most frequent and devastating. These disasters represent high costs and functional disruptions to societies and economies. The consequent breakdown of the economic equilibrium exacerbates the losses of the initial physical damages and generates indirect costs that largely amplify the burden of the total damage. Neglecting indirect damages results in misleading results regarding the real dimensions of the costs and prevents accurate decision-making in flood risk management. To obtain an accurate assessment of total flooding costs, this paper introduces the flood footprint concept, as a novel accounting framework that measures the total economic impact that is directly and indirectly caused to the productive system, triggered by the flooding damages to the productive factors, infrastructure and residential capital. The assessment framework account for the damages in the flooded region as well as in wider economic systems and social networks. The flood footprint builds on previous research on disaster impact analysis based on Input-Output methodology, which considers inter-industry flows of goods and services for economic output. The framework was applied to the 2007 summer floods in the UK to determine the total economic impact in the region of Yorkshire and The Humber. The results suggest that the total economic burden of the floods was approximately 4% of the region's GVA (£2.7 billion), from which over half comes from knock-on effects during the 14 months that the economy of Yorkshire and The Humber last to recover. This paper is the first to apply the conceptual framework of flood footprint to a real past event, by which it highlights the economic interdependence among industrial sectors. Through such interrelationships, the economic impacts of a flooding event spill over into the entire economic system, and some of the most affected sectors can be those that are not directly damaged. Neglecting the impact of indirect damages would underestimate the total social costs of flooding events, and mislead the correspondent actions for risk management and adaptation.

This paper investigates why material throughput remains high in the UK automotive industry when there are opportunities for material efficiency improvements. Informed by socio-technical studies of automobility, the paper emphasises the importance of recognising how decisions regarding material use are always shaped by more than simply cost considerations. Drawing on industry interviews, six interconnected socio-technical factors are identified that guide the vehicle design and manufacturing process. These are: (1) customer preferences; (2) market positioning; (3) techno-economic feasibility; (4) supply chain feasibility; (5) regulation and (6) organisational attributes. These factors can provide insights into the current operating context of the UK automotive industry and help explain why the average material intensity of vehicles and vehicle throughput are increasing. Overall, the paper shows that the efficiency of material use in the UK automotive industry is the outcome of complex and advanced design and manufacturing processes. Understanding these processes and the factors that guide them can potentially increase the likelihood of the automotive industry adopting material efficiency initiatives. [ABSTRACT FROM AUTHOR]

Although sustainable supply chain management (SSCM) has recently received increasing attention among UK manufacturing firms, there is a concern as to whether SSCM practices are being implemented because they are profitable or only because of governance coercive pressure. Thus, the aims of this paper are twofold: first, determining the role of governance in the adoption of SSCM practices; second, investigating whether SSCM practices can be both environmentally beneficial and commercially viable. In light of these issues, this paper develops and empirically assesses an integrated model of governance pressures-SSCM practices-performance. Data was collected from 146 UK manufacturing managers, and analysed using the structural equation modelling method. Exogenous driving forces of governance were found to be precursors to the successful implementation of SSCM practices. The empirical results further suggest that while the implementation of sustainable supply chain management has a positive effect on environmental performance, it does not necessarily lead to improved economic performance, as only sustainable procurement was found to have a positive effect on economic performance. This paper contributes to the literature by highlighting the role of governance in SSCM adoption and performance gains in environmental protection while economic performance is partially compromised. The results also provide useful insights for both managers seeking to adopt sustainable practices and policy-makers seeking to further promote sustainable supply chain. [ABSTRACT FROM AUTHOR]

The student accommodation sector in now the best-performing asset in the UK and US property markets and this is projected to further accelerate, with building refurbishment of existing student accommodations being the preferred method to satisfy growing demand. However, there are no published research studies on refurbishment projects within the student accommodation sector. Refurbishment is an emergent trend to upgrade existing stock to ensure that buildings meet rising energy efficiency demands. Moreover, it is widely affirmed that greenhouse gases contribute to climate change and notably the built environment is a significant contributor, both through its construction and during its operation and use. This paper demonstrates through a comparative case study approach, how greenhouse gases levels can be effectively measured during refurbishment works. There are multiple metrics used for quantification/assessment of greenhouse gases performance and this paper aims to make well-argued recommendations for their best use. Four student accommodation refurbishment projects are presented to compare and contrast differing emission datasets. The results dictate that project cost and duration cannot alone be used to gauge greenhouse gases emissions; more too, in the instance of student accommodation refurbishment, gross internal floor area and the number of rooms offers a more predictable indicator. It is recommended that refurbishment developers reflect on these recommendations when reporting the primary energy and GHG performance of their refurbishment works. Best practice from this research may be adopted into domestic buildings refurbishment projects. [ABSTRACT FROM AUTHOR]

The United Nations Decade of Education for Sustainable Development steered by The United Nations Organization for Education, Science and Culture (UNESCO) since 2005 ended in 2014. It looked into the integration principles, values and practices of sustainable development in all aspects of education and learning, with the intention of addressing the global social, economic, cultural and environmental issues in the 21st century. It has become an essential issue in architectural education to create awareness among future generations of architects to be more sensitive towards the environmental impact of architecture on human behavior. This encouraged every school of architecture to incorporate sustainability knowledge into its curriculum and promote ‘sustainable architectural education’, leading to the questions of: what type of structural model of integration approach being applied in promoting architectural sustainable education? The objectives of this paper are to investigate the type of structural models that have been applied in architectural curriculum in selected schools of architecture in both countries and evaluate the level of emphasis in incorporating sustainability knowledge in the curriculum. Therefore, this paper reviewed the approach of integration principles, values and practices of sustainable development at 10 conveniently sampled architecture schools in the United Kingdom (UK) and the United States of America (USA). Data was collected from their respective web sites and their concepts of integration were reviewed and the distribution of credit hours revealed to determine the level of emphasis considered. Findings showed various paths taken by the different institutions in integrating the knowledge of sustainability into their architectural curriculum. This paper concludes with recommendations for further research into gauging the effectiveness of architectural curricula with integrated sustainability knowledge. [ABSTRACT FROM AUTHOR]

This paper provides a literature review on medicines reuse explaining how this phenomenon has evolved and has being re-interpreted in academic research. Literature review in combination with a descriptive and a qualitative thematic analysis was employed to answer two questions: (i) How the medicines returns phenomenon has been documented and discussed? (ii) To what extent the critical literature on circular and sharing/collaborative economies can be taken as metaphors for the advancement of knowledge to better understand the complexities of medicines returns? After the selection of 125 papers, 10 hubs of collaboration were identified in this research field with early work on reuse stemming from the UK. From the thematic analysis, three outcomes emerged. The first relates to the problem of wastage versus costs and affordability, and the role of stockpiles and misplacement of leftover medicines. The second arises from a chronological description of the selected studies. Using a timeline, recurring debates were identified: prescription costs/sharing; reuse in evolutionary perspective of rational use; affordability and avoidance of wastes; and the role of pharmacists and care in the community/solidary pharmacies. The third outcome delivers metaphors linking critical aspects of circular and sharing/collaborative economies with concepts and situations of medicines reuse. It was found that the circular economy, which is still far from consumer reality, offers a limited contribution as a metaphor for medicines reuse, while sharing/collaborative economy reflects current practices that can be understood as access giving, thus interpreted as a form of affordability. • Medicines reuse is reviewed out of the supply chain context. • Metaphors of reuse are proposed as circularity and shareness. • Behavioural aspects dominate emerging literature on reuse. • Circular economy is a poor metaphor for medicines reuse. • Sharing/collaborative economy are fruitful metaphors of reuse.

Micromobility modes such as scooters, e-scooters, skateboards, or hoverboards has recently emerged as part of the urban landscape. In this paper, we analyze the use of modes of micromobility for commuting. We distinguish between monomodality (commuters using one mode of micromobility only) and multimodality (commuters using micromobility as a complement or substitute to other modes of transport). We apply non-parametric ordered methods to a survey that was conducted in 2018 on mobility users in four European countries. The survey gathered 4873 observations from commuters in France, Germany, Spain, and the United Kingdom (UK). Micromobility commuting is marginal in all four European countries. The sociodemographic characteristics of micromobility commuters are homogeneous and concern mainly male, young, and urban commuters. We find that travel habits account for a large share of the variability explained by the model. Germany has a low level of multimodality, whereas the UK practices complementarity-oriented multimodal commuting. Overall, our results bring new insights showing that micromobility is used as a (partial) substitute to urban transit systems for short distances and as a complement for longer commuting trips made by train. These emerging patterns of commuting require better modal integration between micromobility and public transport, and a more sophisticated design of transport infrastructures. [ABSTRACT FROM AUTHOR]

Sustainable construction can be defined as efficient resource use with ecological design. Three pillars are required to achieve sustainable construction: environmental protection, social well-being and economic prosperity. An increase in sustainable construction awareness among industry stakeholders could help improve levels of implementation. This paper aims to assess levels of awareness among UK practitioners and identify the barriers that inhibit sustainable construction. A mixed-method approach with questionnaire surveys and interviews was adopted. Questionnaire were distributed using MS Forms through social media (e.g., LinkedIn, Microsoft Teams, WhatsApp) and the researcher's contacts. The survey concluded with 127 useable responses. Interviews were also conducted over MS Teams with eight professionals with different backgrounds. Respondents for the interview were conveniently gathered through snowball sampling. Data from the questionnaire survey were analysed using SPSS. Descriptive statistics, Cronbach's Alpha and RII were calculated for the level of awareness of sustainable construction practices and barriers to adoption of sustainable construction. Transcripts from the interview were thematically analysed using NVivo. The findings showed that the industry practitioners have above-average levels of awareness. Sustainable construction practices that respondents were most aware of was reduce, reuse and recycle. Respondents were not as aware of newer sustainable practices such as digital twin. Surprisingly, the most prevalent barrier was not cost. According to the respondents, the most prevalent barrier was a tendency to maintain current practices. Many real-life experiences are documented in this research. Insights into current practice in the industry and key barriers to adopting sustainable construction are identified. Addressing these barriers could improve the adoption of sustainable construction in the UK. • investigates up-to-date techniques for attaining sustainable construction in the UK. • assess the level of awareness among industry practitioners. • identifies the hurdles faced by the industry to attain sustainable construction. • explains the current practices of construction and areas for potential improvement.

Product-Service Systems (PSSs) constitute a family of service-based business models designed to satisfy our societal needs in an economically and environmentally sustainable manner. To date however PSS application has remained niche due to a variety of critical barriers. This paper explores how ‘demand pull’ national government policies could support PSS activity by addressing these barriers and cultivating market demand. Lessons are drawn from a case study of how regulatory , economic incentive , informative and procurement policies have supported Energy Service Company (ESCo) activity in the UK; a sub-set of the PSS family focused on energy service provision. Subsequently five policy recommendations are presented to support PSS activity: (1) balancing economic incentives and regulatory disincentives; (2) promoting indirect policy support; (3) redesigning existing market structures; (4) promoting locally-led PSS activity; and (5) creating stable policy frameworks. The paper warns however that national government policy cannot easily address all PSS barriers, such as customer preferences, international developments, technological progress and inherent business model weaknesses, pointing to the need for other complementary solutions. Furthermore, other governance actors beside national government could also implement PSS supporting policies. [ABSTRACT FROM AUTHOR]

This paper investigates why, how and to what degree supermarkets stimulate upstream eco-innovation in UK milk, beef and bread chains. To answer this question, we aim to enrich the environmental supply chain management literature with insights from innovation studies. The resulting conceptual framework distinguishes three elements: a) motivations for supermarkets to address eco-innovation (internal considerations and external pressures), b) characteristics of supply chains that hinder or enable eco-innovation attempts (e.g. breadth, length, degree of trust), c) mechanisms to stimulate eco-innovation. Regarding this third element, which is our main contribution, we distinguish: 1) economic mechanisms (supermarkets paying farmers more for eco-innovation or imposing eco-performance standards), 2) information exchange and interactive learning in networks (‘innovation systems’), and 3) socio-cognitive coordination through the creation of shared meaning and visions (e.g. roadmaps). We demonstrate the usefulness of this framework with a comparative qualitative analysis of three UK sectors with different degrees of retailer-led eco-innovation: milk, beef and bread. The paper ends with three broader reflections and suggestions for further research. [ABSTRACT FROM AUTHOR]

Collaborative consumption is an emerging socio-economic model based on sharing, renting, gifting, bartering, swapping, lending and borrowing. Made possible through community interaction and, increasingly, use of network technologies, these alternative and more sustainable ways of consuming have attracted growing attention for their potential to prevent new purchases, intensify the use of idle assets and promote reuse of possessions that are no longer wanted. Nonetheless, the uptake of Product-Service Systems (PSSs) that enable collaborative consumption is still very limited. This paper investigates how consumers' values can influence the acceptance, adoption and diffusion of collaborative consumption. It reviews two theoretical frameworks used to understand pro-environmental behaviour, social psychological models of behaviour and social practice theory. Coming from contrasting disciplinary perspectives, these approaches conceptualise values differently. The paper evaluates the possibility of resolving these differences through a mixed methods study. It examines values empirically through a case study of Ecomodo, a UK-based online marketplace where people can lend and borrow each other's objects, spaces and skills, and present the results of a quantitative study which identified and measured value priorities among Ecomodo users through Schwartz's Portrait Value Questionnaire. It concludes with a discussion of the role of values in relation to the introduction and scaling up of PSSs that enable collaborative consumption. [ABSTRACT FROM AUTHOR]

Interest in bioenergy as a viable alternative to fossil fuels is increasing. This emergent sector is subject to a range of ambitious initiatives promoted by National Governments to generate energy from renewable sources. Transition to energy production from biomass still lacks a feasible infrastructure particularly from a supply chain and business perspective. Supply chain integration has not been studied widely providing a deficit in the literature and in practice. This paper presents results from a pilot study designed to identify attributes that helps optimise such supply chains. To consider this challenge it is important to identify those characteristics that integrate bioenergy supply chains and ascertain if they are distinct from those found in conventional energy models. In general terms the supply chain is defined by upstream at the point of origin of raw materials and downstream at the point of distribution to final customer. It remains to be seen if this is the case for bioenergy supply chains as there is an imbalance between knowledge and practice, even understanding the terminology. The initial pilot study results presented in the paper facilitates understanding the gap between general supply chain knowledge and what is practiced within bioenergy organisations.

Research to date has identified cost and lack of support from stakeholders as two key barriers to the development of a carbon dioxide capture and storage (CCS) industry that is capable of effectively mitigating climate change. This paper responds to these challenges through systematic evaluation of the research and development process for the Acorn CCS project, a project designed to develop a scalable, full-chain CCS project on the north-east coast of the UK. Through assessment of Acorn's publicly-available outputs, we identify strategies which may help to enhance the viability of early-stage CCS projects. Initial capital costs can be minimised by infrastructure re-use, particularly pipelines, and by re-use of data describing the subsurface acquired during oil and gas exploration activity. Also, development of the project in separate stages of activity (e.g. different phases of infrastructure re-use and investment into new infrastructure) enables cost reduction for future build-out phases. Additionally, engagement of regional-level policy makers may help to build stakeholder support by situating CCS within regional decarbonisation narratives. We argue that these insights may be translated to general objectives for any CCS project sharing similar characteristics such as legacy infrastructure, industrial clusters and an involved stakeholder-base that is engaged with the fossil fuel industry. • Cost reduction and stakeholder support are essential for CCS industry development. • Acorn is aimed to develop a full-chain CCS system at minimum cost by the 2020s. • Infrastructure re-use and staged investment and development enable cost reduction. • Stakeholder and local community engagement is key to promote a just transition. • The Acorn experience can be implemented in regions with similar CCS needs.

The paper is part of what we can call " post New Public Management (NPM) studies " which denounce that the policies of austerity and competition have made local public transport fragmented and less attractive for customers. These studies that indicate the need for greater coordination within this sector as a condition of social and environmental, and not only financial, sustainability are increasingly numerous. We show how the public transport legislative evolution in UK (more strictly Great Britain) has aimed towards the assurance of more coordination into a fragmented sector. However in its last stage, the Bus Services Act 2017, we find not only more incentives to increase coordination but the 'rehabilitation' of a contested concept such as the integrated transport planning. Specifically, we show that the 'rehabilitation' of the integrated transport planning did not happen immediately but gradually over the years through several reforms. During this transition, both negative and positive aspects, and the tensions between competitive mechanisms and coordination mechanisms have lived together. This tension demonstrates the challenge of finding an appropriate role for public and private actors to make public transport fully sustainable. The case of Great Britain shows that transport sustainability must be found in a mix of mechanisms: not only market and partnership but also hierarchical mechanisms, such as an integrated and coordinated planning.

The increasingly efficient use of scarce resources is a central theme in the gradual transition towards a circular economy. Hazardous materials represent a category of resources that is often difficult—and potentially risky—to transport, store, or neutralize. As a result, hazardous materials are rarely included in closed material loops. The present paper analyzes HorsePower, a business concept centered around an innovative way of utilizing horse manure. Horse manure is generated in millions of tons in horse-rich countries such as the UK, Germany, and France. It is a hazardous resource, as it may spread diseases, and cannot be disposed of or landfilled economically. The content analysis of 21 semi-structured interviews carried out with different business actors participating in the HorsePower business network reveals that the success of HorsePower stems from its ability to combine the complementary capabilities and material needs of a relatively complex network of business actors including stables, sawmills, logistical service providers, and heat and power plants. Each actor receives added value; the benefits from participation are greater than the sacrifices of participation. Furthermore, the findings show that certain types of hazardous resources, when combined with resources produced by another actor, may be burned efficiently and safely in specific power plants, reducing the need for other types of fuel. The observations imply that novel approaches for effectively sharing ideas and resource needs across organizational boundaries are needed to facilitate the development of additional innovative CE business concepts, leveraging both actor-specific capabilities and intra-actor resource dependencies.

Biscuits are a major product category in the global confectionary sector. Despite this, their environmental impacts are poorly characterised. Therefore, this paper sets out to evaluate the life cycle environmental sustainability of the following widely-consumed types of biscuit, both at the product and sectoral levels: crackers, low fat/sugar, semi-sweet, chocolate-coated and sandwich biscuits with chocolate or vanilla cream. The results obtained through life cycle assessment demonstrate that, in addition to being healthier, low fat/sugar biscuits have the lowest impacts across most of the 18 categories considered. Chocolate-coated biscuits are environmentally the least sustainable. The most significant life cycle stage for all types is the raw materials production, causing 41%–61% of the total impacts, with flour, sugar and palm oil being the key hotspots. Replacing palm with rapeseed oil would improve five impacts but worsen another five, including a 34% increase in agricultural land occupation and marine eutrophication. Therefore, the cultivation and production of palm oil, rather than its replacement, should be targeted for improvements. The second most crucial stage is manufacturing, contributing up to 54% of the impacts, followed by transport with up to 35%. Reducing energy consumption by 25% in manufacturing would reduce primary energy demand by 8%–12%, fossil fuel depletion by 9%–12% and global warming potential by 6%–9%. The latter would increase by 55% if land use change related to cocoa was involved, despite a very small amount of cocoa in the biscuits (∼1%). The analysis at a sectoral level in the UK, the leading consumer of biscuits in Europe, reveals that biscuits contribute 7.4% of primary energy demand and 0.5% of greenhouse gas emissions of the whole UK food sector. These results can help guide manufacturers in mitigating the hotspots in the supply chain and consumers in selecting environmentally more sustainable biscuits. • The environmental sustainability of six types of biscuit is evaluated for the first time. • Low fat/sugar biscuits have the lowest impacts and chocolate-coated the highest. • Global warming potential of chocolate biscuits is 55% higher with land use change. • Flour, sugar and palm oil are the key hotpots, followed by biscuits manufacturing. • Biscuits contribute 7.4% of energy demand and 0.5% of GWP of the UK food sector.

Affecting millions of Europeans, energy poverty is increasingly high on the political agenda. This paper compares space and water heating demand at household level in Germany and in the United Kingdom (UK) between 1991 and 2015. The elasticities of consumption of space and water heating with respect to price, income and heating degree days (HDD) are examined using non-parametric models. Domestic heating consumption is highly elastic with HDD in both countries and HDD elasticities are found to be higher in the UK. From a certain income threshold, heating demand decreases as income increases in German households whereas demand rises with higher incomes in the UK. High price elasticities indicate that UK households are very responsive to energy conservation measures, therefore implying that a pricing policy will effectively reduce heating consumption. However, in Germany, the impact of pricing policies is unclear. Thus, the most effective policy measure to decrease domestic heating consumption in Germany in the long-run should be one which targets improvements of building envelope performance levels.

This paper details the specific aims and purposes of the Damage Assessment Tracking Criteria; a series of evaluation tools designed to aid in remanufacturing inspection operations. The background and justification of this model, which is detailed in a separate work, identifies ill definition and an over reliance on opinion as barriers to effective inspection activities. Analysis of this issue led to the building of the Damage Assessment Tracking Criteria; a 4-model foundation that aims to provide a more comprehensive and more structured approach to the inspection stages of the typical remanufacturing process. Through expert opinion this model was evaluated multiple times. One review was used to gauge the level of idea communication within an academic situation, this was followed up by external industrial reviews of the model by those most likely to utilise it during industry practice. After extensive feedback and modification the final model assessment was carried out with an expert panel that were instructed to be as critical as possible with the model in order to ensure that its evaluation was as robust as possible. The results of these reviews were all on the positive side of the scale. Multiple statements regarding the potential value and suitability of each model aspect and justification for their use was presented in the format of an evaluation form which was used by those involved to present their findings and feedback. Negative feedback was addressed and successful modification yielding more positive results in the next evaluation was achieved. Though walking the line between specificity and generic was noted to be the most difficult factor to consider when developing the models, the final findings of the evaluation show that significant value was perceived by those operating within industry. The potential benefits of customised variants of the models is acknowledged by all parties as a possible future avenue of research. [ABSTRACT FROM AUTHOR]

Energy load forecasting is essential to effectively optimise the use of energy for the purpose of smart grid operation. In this work, a focus is placed on Short-Term Load Forecasts (STLF) using measured heat pump data from the UK utilising the Long Short-Term Memory (LSTM) method. A load forecasting program is developed to forecast the electricity consumption of heat pumps based on historical data. LSTM is compared to Backpropagation Neural Network (BPNN), Seasonal Autoregressive Integrated Moving Average (SARIMA), Random Forest (RF) and Holt-Winters Exponential Smoothing (ES). The best average Mean Absolute Percent Error (MAPE) of 1.59% is achieved for the test data set by LSTM, which outperforms other models compared and a number of models presented in papers in the literature. By conducting the Wilcoxon signed-rank test, it is proven that the prediction accuracy improvement of LSTM compared to other models is statistically significant with the exception when comparing with RF with the training data. The impact of data aggregation resolution to forecast accuracy is investigated. The proposed LSTM model performs best on 1-h resolution data compared with other resolution time periods. The results of the LSTM model are integrated with Home Energy Management Systems (HEMS). The electricity costs of the HEMS are compared when using forecasted and measured heat pump data respectively. The results indicate an average percentage difference of 2.06% between the predicted and the actual electricity cost of HEMS for the test data. Furthermore, this paper presents a combined neural network and Particle Swarm Optimisation (PSO) model to develop an optimised energy management system while proving the effectiveness of the LSTM algorithm. • A LSTM algorithm is used to forecast the electricity consumption of heat pumps. • The proposed forecast model outperforms models found in the literature. • The Wilcoxon signed-rank test is used to prove the effectiveness of LSTM model. • The impact of data aggregation resolution to forecast accuracy is investigated. • The load forecast model is integrated with a Home Energy Management System model.

Effective Education for Sustainable Development (ESD) requires appropriate pedagogies that engage learners in transformative learning. These pedagogies include reflective and active learning, involving experiential, collaborative and learner-centred activities. This paper discusses student experiences and perceptions of an interdisciplinary social science ESD course at a UK university that incorporated reflective and active learning by using a 'flipped classroom' (FC) design and innovative assessments. FC creates time in class for reflective and active learning by moving content acquisition to pre-class study. Adoption of the flipped classroom in social sciences is rare and literature on use of FC for ESD is very scarce; hence this paper offers valuable insights into the design of a flipped social science ESD course, and participants' responses. Results of two surveys demonstrate very positive student perceptions of the course, and illustrate several benefits of the FC design. Over 90% of respondents agreed that in-class active learning exercises made the classes more engaging and the material more memorable than usual, offering useful opportunities to put information/learning into practice, with most students expressing strong agreement. In-class mini-lectures were nevertheless also appreciated, as were reflective practices. A large majority of the students considered the workload reasonable. Findings also reveal the importance of incentivising pre-class preparation using graded assessments such as quizzes, which additionally helped students understand/remember content, and gave confidence about contributing in class. It is clear that the active and reflective learning that FC facilitates engages students in ESD. The paper concludes by offering recommendations for successfully implementing this approach. • Discusses an interdisciplinary ESD course that uses a 'flipped classroom' design. • >90% of students said in-class active learning exercises made classes more engaging. • Reflective practices and in-class mini-lectures were also appreciated. • Incentivising pre-class preparation using graded assessments is important. • Flipped class facilitates active and reflective learning that engages students in ESD.

Landfill restrictions on certain materials and products have provided the impetus to seek for a more sustainable utilisation of waste in a circular economy. These restrictions compounded with legislation and value factors necessitate an urgent solution to address the issue of carbon or glass fibre reinforced composite waste disposal. There is currently no mutual agreement on waste ownership among stakeholders. This study examined composite manufacturers in the United Kingdom and determined the waste volumes available within these companies. A new approach that combined mathematical modelling of supply chain complexity, centre-of-gravity method and K-Means algorithm was developed to determine the optimum location of third parties that could process waste for a number of supply chain providers. The paper is a presentation of new knowledge and proposes a scientific approach for identifying possible optimum locations for recycling centres. More significantly, this process could be used for clustering and reducing supply chains complexity to enable the setting up of multiple and optimally located recycling centres. The results have indicated that the approach could minimise carbon footprint and greenhouse gas emission associated with transporting cores or waste to processing centres. This work is of generic importance that could be implemented across other waste and aspects of a circular economy such as remanufacturing. [ABSTRACT FROM AUTHOR]

Abstract Ice cream is consumed daily worldwide and yet its environmental impacts are scarcely known. This paper presents a first comprehensive life cycle assessment of market-leading vanilla and chocolate ice creams, considering both regular and premium products. The results suggest that their impacts are broadly similar across the 18 impact categories considered. For the majority of the impacts, chocolate regular ice cream is a slightly better option than the other varieties. Overall, the regular versions of the product have lower environmental impacts than the premium. Raw materials contribute most to the majority of impacts (>70%). The exception is ozone depletion, which is mainly due to refrigerated storage at the retailer (95%). The impacts are highly sensitive to the duration of storage and the type of refrigerant. Furthermore, the global warming potential of chocolate ice cream is very sensitive to land use change associated with cocoa beans cultivation, increasing the impact by 60%. Considering annual consumption of ice cream in the UK, the total primary energy demand contributes to 3.8% of energy consumption in the whole food sector while greenhouse emissions contribute 1.8%. Future improvements in the supply chain should focus on milk and cocoa production, reduced storage time and types of refrigerant used. Product reformulation to reduce the amount of milk (fat) and sugar should also be considered, in line with the emerging health-driven market trends. In addition to industry and policy makers, the findings of this study will be of interest to consumers, enabling them to make better choices with respect to environmental impacts of most popular ice creams.

The Smart Meter Implementation Programme (SMIP) is arguably one of the most expansive and complex smart meter programmes globally. The UK government regards smart meters to be enablers of a low-carbon energy grid and has set out ambitious consumer-orientated aims within their programme across England, Scotland, and Wales. Despite considerable amount of research on how consumers will (or not) engage with smart meters, media discourses, where some public debates about smart meters are created and reproduced, have received little attention. This paper presents a content analysis of how smart meters are discussed within 11 years of popular print media coverage. A collection of nine discourses are identified: Four of these – “empowered consumers”, “energy conscious world”, “low-carbon grid”, and “future smart innovation” – depict smart meters as a harbinger of positive social change. Five of these – “hacked and vulnerable grid”, “big brother”, “costly disaster”, “astronomical bills”, and “families in turmoil” – represent smart meters as negative forces on society. The results show that discourses and associated storylines mainly represent continuous struggles over particular socio-technical promises linked to smart meters. Somewhat missing are attempts to open up the smart energy debate to broader issues of democracy and energy justice within the print media coverage. [ABSTRACT FROM AUTHOR]

Abstract: The literature on environmental champions emphasises the effective action of environmentally committed individuals. This paper draws on case studies of process technology investment projects in chemical and dairy companies in the UK and Sweden. The analysis is based on a political process perspective on organisations. By analysing the career histories of environmental champions as well as their behaviour in the investment projects, the paper shows how their championing behaviour is shaped by dynamic interaction with the organisational context, as well as a broader range of motivations and interests, including career opportunities and private life concerns.

This paper reviews the factors influencing the development and sustained operation of regional industrial symbiosis (IS) networks and discusses the roles a coordination body can play to alter these factors so as to catalyse the development and functioning of such networks. These are analysed within the context of experiences gained in the early stages of three regional IS programmes under development in the UK, and of the recently launched national IS programme (NISP) that they are part of. It is stated that the policy framework in the UK has elements supportive of such networks to evolve, and the regional public bodies are favouring their development. Based on differences among studied cases, it is argued that the nature of companies’ operations and industrial history in the regions, the extent of peer pressure, the positioning of the coordinating body in the region, and its approach to awareness raising and recruitment have major influence on the progress of the programmes. Finally, the paper emphasises the importance of aligning the characteristics of emerging operations with the longer-term sustainability requirements. If accepted, this challenge assigns additional responsibilities to the coordinating parties. [Copyright &y& Elsevier]

Residential demand response using low carbon technologies can potentially offer energy flexibility to the electricity network along with integration of renewable generation. This paper seeks to empirically evaluate the effectiveness of residential demand response trials on a low voltage feeder of a secondary substation in Barnsley (UK). The study used a sample of 14 well-insulated dwellings equipped with home batteries, heat pumps and solar photovoltaic systems coordinated using automated control. Statistical analysis was undertaken using time-series monitoring data obtained at the individual dwelling level, dwelling sample and at the feeder level of the local low voltage network. Resident experience of the trials was assessed through qualitative data obtained from household telephone surveys. Over three weeks of trials, daily demand response interventions of 2 h duration were applied to the sample of 14 dwellings. For evening peak times, the mean reduction in grid electricity import was found to be 1.3 kWh (67%) per dwelling for turn-down interventions which aimed to minimise import. For turn-up interventions between 1 and 3 pm, the mean increase in grid electricity import was found to be 5.8 kWh (645%) per dwelling. The effect of interventions was measured at the low voltage network level for two single-phase feeders, where penetration of trial homes was approximately one-third. A reduction in mean real power up to 21% was observed for turn-down interventions as well as an increase in real mean power up to 307% for turn-up interventions. In general, the trials had little effect on residents in terms of thermal comfort, hot water availability, noise disturbance or disruption to routines, and where such effects were noticed, they were broadly acceptable. The widespread implementation of residential demand response schemes will require increased roll-out of time-of-use tariffs, enhanced resident support and extensive monitoring of low voltage feeders in electricity substations.

This paper examines the causal interactions between energy consumption due to cryptocurrency mining activity and electricity return and volatility patterns across the power markets in the U.S., U.K. and Europe. We find that the effect is heterogeneous across the different power markets examined, while the effect of mining activity is consistently focused on return volatility. Accordingly, our findings provide robust evidence of the volatility effects of mining activity in power markets, suggesting that the crypto mining-power market nexus primarily entails risk effects, an issue of particular concern for hedgers whose goal is to stabilize energy costs in their operations.

Vehicle fleets are considered an important context for the deployment of innovations such as electric vehicles and vehicle-to-grid (V2G) technology. Fleet vehicles constitute a significant share of vehicle registrations, yet little research has been conducted into how the make-up of the changing fleet market could influence upscaling of innovations. This paper presents an in-depth study of the fleet market in the United Kingdom and assesses synergies between V2G and vehicle fleets by analysing socio-technical trends. The approach taken allows for analysing the role of users and markets in upscaling socio-technical transitions. The paper provides a system-level account of the fleet market, and shows how changing user characteristics, the rise of telematics, Low Emission Zones and changes to business operations and labour relations present specific drivers and challenges for V2G. It is concluded that user-related changes in the market environment are highly influential in shaping the upscaling trajectory of sustainable innovations such as V2G. • User-centered analysis of market dynamics in socio-technical transition. • Fleets are a potential domain for the application of V2G. • Fleet market trends have contradictory implications for V2G uptake. • Changes in fleet management practices and vehicle use patterns are influential. • Labour relations with drivers could impact V2G potential.

Public procurement is increasingly recognised as a tool to promote more sustainable forms of food production. As the negative consequences of the food system on ecological and human health have become more apparent, public institutions have come under increasing pressure to purchase food in a way that promotes environmental, social and economic benefits. This is reflected by a growing number of initiatives that link the provision of healthy food with support for more environmentally benign food production. This paper explores the potential impact of public procurement on the business strategies of small food producers. In doing so, it seeks to widen the understanding of how demand can support more sustainable forms of food production and supply. The study is based on a series of qualitative interviews with producers and caterers who have participated in the Food For Life programme based in the UK. The impact of the programme framework is explored with respondents and thematically analysed to distil a series of key impact types and contextual variables. The paper discusses the potential for steering business change within food businesses using public procurement strategies. The unique nature of food systems and the complex relationships with human and ecological health lead to a distinct set of challenges and opportunities for advocates of sustainable procurement. Image 1 • An exploratory study on the impact of sustainable food demand on firms. • Interviews were thematically analysed to elucidate key impacts and contextual factors. • The relationship between contextual factors and impacts is schematically presented. • The potential for public procurement to stimulate sustainable food production is discussed.

This article offers a methodological tool that assesses a company's commitment to sustainability by analysing its business model (which is defined here as a description of processes through which organizations implement their competitive strategies and create value). Insofar as they are considered a key driver for long-term profitability, sustainability strategies should involve a company's value creation processes — that is, a company's business model. This paper specifically examines the extent to which mining companies engage in sustainability by performing content analyses of their business model disclosures. Our empirical analysis focuses on the UK mining industry because this sector often struggles with a host of societal, organizational, and environmental issues, and because UK mining companies are obliged to describe their business model in their strategic reports. In order to determine whether (and how) companies implement sustainability strategies in their business model, we perform a content analysis of the business model disclosures of 16 FTSE All-share index UK mining companies, for a total of 1048 text units. Our results suggest that mining companies have opted for a selective and soft approach to sustainability. Although Air, Energy, Water, Local community engagement, Environmental protection, and Labour conditions are often addressed in the business models of UK mining companies, there is very little evidence to suggest that concrete initiatives were actually implemented in other areas. In fact, some topics are completely ignored (Raw materials), almost completely ignored (Waste, Corruption and Lobbying, Local employment), or discussed in a predominantly descriptive manner (Human rights, Opportunity and equality, Recruitment and bargaining, Training). The practical implications of this study are twofold. First, we offer a new means of investigating how companies engage in sustainability by performing content analyses of their business model disclosures. Secondly, we offer a detailed discussion of how sustainability affects value creation processes in the UK mining industry. [ABSTRACT FROM AUTHOR]

The grocery retail sector produces substantial amounts of food waste. Despite the growing public recognition of its negative socio-economic and environmental implications, the issue of food waste in supermarkets has been under-researched. In addition to a small number of studies, the focus has been on the quantification and characterisation of food waste streams in grocery retail. Little attention has been drawn to managerial attitudes and approaches to food waste mitigation. Managerial research is critical to aid in understanding how the issue of food waste is tackled on the ground. This paper plugs this knowledge gap by investigating how managers of major UK grocery retailers address the problem of food waste in their day-to-day operations. It adopts content analysis of corporate materials and a qualitative method of primary data collection and analysis to explore managerial attitudes and approaches to food waste mitigation in supermarkets of the South East Dorset conurbation (UK). The study demonstrates that, although the problem of food waste is recognised by UK grocery retailers, it is not seen as being of critical importance. In mitigation terms, while food waste recycling and price reductions are mainstream, food donations are ad-hoc and largely occur at managerial discretion. Poor consumer awareness, imperfect regulation, inflexible corporate polices and limited control over suppliers hamper more active involvement in food waste mitigation. Based on findings, policy-making and managerial recommendations on how to optimise food waste management practices in the UK grocery retail sector are revealed. [ABSTRACT FROM AUTHOR]

The UK electricity grid is expected to supply a growing electricity demand and also to cope with electricity generation variability as the country pursues a low-carbon future. Molten Salt Reactors (MSRs) could offer a solution to meet this demand thanks to their estimated low capital costs, low operational risk, and promise of reliably dispatchable low-carbon electricity. In the published literature, there is little emphasis placed on estimating or modelling the future impact of MSRs on electricity grids. Previous modelling efforts were limited to quantifying the value of renewable energy sources, energy storage and carbon capture technologies. To date, no study has assessed or modelled MSRs as a competing power generation source for meeting decarbonization targets. Given this gap, the main objective of this paper is to explore the cost benefits for policy makers, consumers, and investors when MSRs are deployed between 2020 and 2050 for electricity generation in the UK. This paper presents results from electricity systems optimization (ESO) modelling of the costs associated with the deployment of 1350 MW e MSRs, from 2025 onwards to 2050, and compares this against a UK grid with no MSR deployment. Results illustrate a minimum economic benefit of £1.25 billion for every reactor installed over this time period. Additionally, an investment benefit occurs for a fleet of these reactors which have a combined net present value (NPV) of £22 billion in 2050 with a payback period of 23 years if electricity is sold competitively to consumers at a price of £60/MWh.

Legislation and fiscal policies have remained the key drivers of construction waste minimization. It has often been suggested that reducing waste to the landfill does not only require improvement on existing waste management policies and fiscal framework; there is a need for adequate inputs from the construction professionals. As a means of engendering effective waste management policies, this study explores industry practitioners’ viewpoints on effective policies for minimising waste landfilled by the UK construction industry. Using exploratory sequential mixed method approach, qualitative and quantitative methods were used. In the first phase of the study, data was collected through focus group discussions with 24 experts from the UK construction industry. Findings from the qualitative study served as an input into a questionnaire, which was used to elicit a wider opinion from 63 experts at the quantitative stage of the study. The study suggests that for waste management legislation and policies to effectively drive construction waste minimization, six key measures are important. These include (i) provision of tax breaks and incentives to good waste performers and waste management businesses; (ii) increased targeting of design stages in policies; (iii) Extension of sustainable design appraisal systems by allocating more points to proven waste performance measures; (iv) increased stringency of legislative measures by requiring use of proven waste efficient design, procurement and construction methods; (v) increased stringency of fiscal policies by increasing penalties for poor waste performance; and (vi) corroboration of policy requirements with enablers and facilitators. The strategies through which each of the legislative and fiscal measures could be tailored and enhanced are discussed in the paper. By embracing both stringent and palliative policy measures suggested in the study, substantial construction waste could be diverted from landfill. [ABSTRACT FROM AUTHOR]

In the interest of climate change mitigation, policy makers, businesses and non-governmental organisations have devised initiatives designed to reduce in-use emissions whilst, at the same time, the number of energy-consuming products in homes, and household energy consumption, is increasing. Retailers are important because they are at the interface between manufacturers of products and consumers and they supply the vast majority of consumer goods in developed countries like the UK, including energy using products. Large retailers have a consistent history of corporate responsibility reporting and have included plans and actions to influence consumer emissions within them. This paper adapts two frameworks to use them for systematically assessing large retailers' initiatives aimed at reducing consumers' emissions. The Framework for Strategic Sustainable Development (FSSD) is adapted and used to analyse the strategic scope and coherence of these initiatives in relation to the businesses' sustainability strategies. The ISM ‘Individual Social Material’ framework is adapted and used to analyse how consumer behaviour change mechanisms are framed by retailers. These frameworks are used to analyse eighteen initiatives designed to reduce consumer emissions from eight of the largest UK retail businesses, identified from publicly available data. The results of the eighteen initiatives analysed show that the vast majority were not well planned nor were they strategically coherent. Secondly, most of these specific initiatives relied solely on providing information to consumers and thus deployed a rather narrow range of consumer behaviour change mechanisms. The research concludes that leaders of retail businesses and policy makers could use the FSSD to ensure processes, actions and measurements are comprehensive and integrated, in order to increase the materiality and impact of their initiatives to reduce consumer emissions in use. Furthermore, retailers could benefit from exploring different models of behaviour change from the ISM framework in order to access a wider set of tools for transformative system change.

The UK Government has set out ambitious plans for all new domestic and commercial buildings to be zero carbon rated by 2016 and 2020 respectively. These are some of the most progressive environmental targets for the built environment in the western world. However, there are also other sustainability issues that need to be addressed by the UK construction industry, particularly negative impacts from the generation of waste. Currently, 100 million tonnes of construction waste, including 13 million tonnes of unused materials, is generated each year, with only 20% currently capable of being recycled. The majority of this waste ends up in landfill, contributing to further pollution of the biosphere. The literature suggests that these negative impacts result from a variety of causes, including ineffective leadership, ingrained cultures, outdated technologies and poor logistics. There are a number of innovative projects within the UK, particularly at a local level, that pose the question as to whether bottom up approaches may be more successful than top down policies, as set by national and local government. This paper presents a case study demonstrating the former approach within the construction industry. Research and consultancy has been undertaken collaboratively between industry, academia and professional practice in the production of 15 individually designed sustainable dwellings in the North East of England. This project has employed Building Information Modelling (BIM) as a new collaborative working platform, aligned to the Modern Method of Construction (MMC). By situating this inquiry within an authentic case study it has highlighted ineffective strategies, policies and leadership, which have prevented full exploitation of the potential of BIM and MMC towards sustainable production. This inquiry supports the integration of the Framework for Sustainable Strategic Development (FSSD) into construction procurement, as a method for implementing bottom up leadership in a value driven project.

Industrial processes such as Portland cement manufacture produce a large proportion of anthropogenic carbon dioxide and significantly reducing their emissions could be difficult or expensive without carbon capture and storage. This paper explores the idea of synchronising shutdowns for carbon capture and storage installation with major shutdowns required to refurbish major process units at industrial sites. It develops a detailed bottom-up model for the first time and applies it to the United Kingdom's cement industry. This research demonstrates that several policy and technology risks are not identified by the top-down models and it highlights the importance of reducing shut-down times for capture plant construction. Failure to do so could increase installation costs by around 10 per cent. This type of approach, which is complementary to top-down modelling, and the lessons learned from it can be applied to other capital- and energy-intensive industries such as primary steel production. It provides important information about what actions should be prioritised to ensure that carbon capture and storage can be applied without extra unnecessary shutdowns which would increase the overall cost of carbon dioxide mitigation and could delay action, increasing cumulative emissions as well.

In November 2016, Siemens Gamesa started construction of its £310-million, off-shore wind turbine blade assembly facility in the city of Kingston upon Hull in the UK. This paper adopted a mixed method approach, that is, maps, charts and tables and meta analysis to investigate the social acceptability of local residents to such investments using feedback from three residents' surveys conducted over a period of nearly 3 years. The study is a first of its kind as it presents a real case study of social acceptability of a large manufacturing facility, located close to a residential area, that significantly changed the landscape of the area. The findings indicate that residents on the whole favour such investments because of the economic opportunities. For instance, over 1000 direct jobs were created with the Office for National Statistics reporting a growth of 4.2% in Kingston upon Hull's economic output in 2016–2018. Similarly, Demos-PwC Growth for Cities Index 2018 ranked it, the third-most improved UK city to live and work. However, there were some concerns especially from those living close to the facility regarding issues like noise from ships docking and loading during the night and the obstruction of the scenery of the estuary by an erected sound barrier. The study also shows that it is important for the investors to work closely with local stakeholders and residents to maximise the returns whiles minimising the negatives. • Essential to match social-economic benefits to environmental considerations that may arise. • Would-be investors and local community must collaborate to maximize benefits from investments. • Environmental issues play a major role in acceptance of community located facility. • Production and use of wind turbines, overall, impact positively the environment.

Road transportation being a leading source of greenhouse gas emissions and air pollution, is now resulting a move away from the traditional internal combustion engine to electric vehicles (EVs), currently powered by battery technology. This paper examines end-of-first-life applications of EVs batteries in a low-carbon circular economy following global transition to EVs and net zero economy. Semi-structured interviews were conducted with key actors within the EV industry in the UK. Drawing on Stahel closed-loop solutions, a qualitative analysis of the transcripts of these interviews revealed the need for business models towards coherent low-carbon circular economy of the value chains. This paper reveals a whole range of issues relating to: extraction of battery critical raw minerals (e.g. ethical concerns); manufacturing (e.g. lack of policy frameworks addressing value chain emissions); distribution and sale (e.g. gaps in circular built economy strategy and transition plan); use (e.g. lack of a functioning market for end-of-first-life batteries) as well as research and innovation (e.g. lack of infrastructure to deal with end-of-first-life cells). The views on policy weaknesses testifies to the need for close-loop business model to not only focus on recycling battery raw minerals or repurposing battery for energy storage applications. But, should consider many aspects of an innovative policy strategy and product's global value chain, accounting for: equitable jobs, critical raw minerals dependency, circularity governance and industry standards, protecting the natural environment, tackling emissions and ensuring sustainable consumption and production patterns. The study highlights establishing key trade-offs within policy goals considering the global value chains, as well as, harnessing synergies between social, economic and environmental goals. The paper concludes that a low-carbon close-loop business model should integrate the triple objectives of making positive impact on people, planet and profit, and developed on the basis of legislation, collaboration, research, investment, and incentives guiding to achieve the Global Goals. • A circular economy business model for transitioning to electric vehicles in a low carbon economy is examined. • Principles of circular economy has extraction, manufacturing, distribution & sale, use, recycling & innovation dimensions. • Raw minerals dependency, value chain ethical issues, transition plan and lack of legislative frameworks are major concerns. • Stakeholders hold views on weaknesses on lack of business model addressing value chain circular and low-carbon solutions. • Imperative to recognise nexus and circular thinking in policies and future studies towards sustainable futures.

The paper aims to understand the impacts of the spatial and temporal diffusion of Anaerobic Digestion (AD) on the Water Energy Food (WEF) nexus and to quantify the associated environmental, social and economic benefits. Contemporary tight carbon reduction targets urge the need to deploy renewable energy technologies however due to interdependencies across the WEF nexus, various technologies are beneficial for some but not all sectors. This paper quantifies the impacts of future possible AD technology diffusion choices on the environment, society and economy. This can aid decision makers to identify the potential consequences of various AD alternatives within the next three decades. The study considers an integrated WEF nexus approach and accounts for the interdependencies within the nexus. This was done by developing an Agent-Based Model (ABM) and simulating the relations between the main players within the nexus, thus examining the upscaling of AD diffusion and its consequences for water consumption, energy production, transportation, landfill use, food waste processing and digestate generation. Three future WEF nexus scenarios, that reflect potential alternatives of society and technology in Great Britain up to 2050, were utilised by the ABM implementation to test the sensitivity of AD diffusion choices. These scenarios describe possible changes to lifestyle, governance, technologies, climate, and social structures. Accounting for the uncertainty associated with such future simulations, the Monte Carlo method was employed to estimate the potential variations in scenario outputs. Results suggest that decentralisation results in the largest carbon reduction, but can incur more costs. Centralisation consumes 35% more water but produces 37% more energy (biogas). The paper has visualised the scenario outputs graphically to highlight the consequences of neglecting the inter-relationships between environmental, social and economic aspects of AD. • The future diffusion of AD plants in GB was simulated using an Agent-Based model. • Future energy scenarios were utilised to reflect different lifestyles and economies. • Intersectoral complex dependencies in the water-energy-food nexus were considered. • Impacts of AD implementation on environment, society and economy were quantified. • Trade-offs were assessed between the impacts of centralised & decentralised scenarios.

Conserving the planet for the next generation has come to be an essential component of sustainable development, with "future generations" being the term most frequently included when citing definitions of sustainable development. However, beyond words, does a concern for a future beyond the current generation have any bearing on actions taken in the present? This paper examines the concept of generativity (concern for the future) as a component of sustainable development and specifically, in relation to green consumption. A sub-set of data gathered through a survey which sought to explore constructs for a model for green consumer behaviour has been used to reflect particularly, on the relationship between generativity and green behaviour. Further, the data has been deployed to explore comparisons on the basis of gender and age but also differences between respondents in the UK and Portugal. The results show a positive correlation between generativity and green consumption values, as well as between generativity and buying behaviour, and generativity and prosocial attitude. The data does not support gender difference in terms of levels of concern, or differences between the two countries but age, is shown to be an influencing factor. The paper concludes that the concept of generativity merits further exploration. Image 1 • Generativity (concern for the future) is positively correlated with and green consumption values and buying behaviour. • Generativity is positively correlated with prosocial attitude. • Generativity is not influenced by gender. • There were no differences in generativity between the sample in the UK and Portugal. • There are differences in levels of generativity between those with children and those without.

The food processing sector has a considerable environmental impact, due to large volumes of food and packaging waste. Eco-innovations present an important opportunity to reduce this impact. Yet, initial insights suggest that new technologies face considerable challenges to their adoption. The eco-innovation adoption literature has overlooked the food processing sector. The purpose of this paper is to examine the barriers inhibiting the adoption of waste reducing eco-innovations in the food processing sector. We present four detailed case studies of new technologies at different stages of adoption in the UK and Netherlands. The findings reveal ten barriers to the adoption of waste reducing technologies in the food processing sector. The barriers identified include concerns over the influence of technologies on the product's characteristics, its retailing, and a perceived lack of consumer demand. These barriers arise from the powerful influence of retailers within the food supply chain, the influence of technologies on in-store point of sale displays, and the need for distribution trials. We conclude that the adoption of new technologies requires simultaneous acceptance by both food processor and retailers. The paper provides recommendations for policy makers and innovation managers to increase the adoption and diffusion of waste reducing technologies in the food processing sector, as well as implications for future research. • Interconnected barriers are identified across key members of the food supply chain. • Specific characteristics of waste reducing eco-technologies impede their adoption. • Retailers role in the adoption of waste reducing technologies is uncovered. • Policy action is required to promote adoption at each level of the supply chain.
