A critical shift is required to meet the challenges reflected in the sustainable development goals. Policymakers in the EU are betting on a transition from a linear to a circular economy to make this happen. Public procurement is vital in this context, e.g., accounting for 20% of Swedish GDP, with circular public procurement being critical to the transition. Until now, the research focus in this area has been narrower, concentrating on, e.g., IT equipment or furniture. However, plastic medical products have not been addressed despite generating substantial environmental impact and offering a tremendous upside. To enable the application of circular economy strategies in this context, changes are required on two ends: the design of the products and the criteria under which the products are procured. Indicators are the central basis of decision-making in any purchasing decision and are considered powerful enablers and drivers of the transition to a circular economy. This paper reviews circular indicators as a starting point toward guidelines for the circular design and procurement of plastic products in the healthcare sector. Based on this, critical factors for developing a comprehensive indicator for the design and procurement of circular plastic medical products are identified. [ABSTRACT FROM AUTHOR]

District heating and cooling systems have been present on the European market for more than a century, constantly evolving into more efficient energy infrastructures important for decarbonization of the heating and cooling sectors. With roughly 17,000 operational district heating systems, serving over 70 million citizens, currently, the final energy consumption attributed to district heating in Europe is estimated at over 450 TWh. As the European district heating and cooling sector varies extensively in every analyzed aspect, there are vast differences between European countries regarding technical preferences, technological development, market structure and regulatory frameworks of these systems. The main purpose of this paper is to provide a comprehensive overview of the present status of the district heating and cooling systems in Europe with insight(s) and suggestions into future trends. In addition, the provided data serves as a valuable baseline for future research. Finally, this paper draws attention to the new socio-demographic approach, observed when analyzing the district heating and cooling systems, that has been recently introduced into the scientific community. This new approach also reveals the opportunity for creating new indicators that will influence the modeling of existing and future district heating and cooling systems. • Provides a review on ongoing trends in European district heating and cooling sector. • Analyses European DHC systems from technological, market, and regulatory aspect. • Provides an overview on commonly used performance indicators and energy models. • Discusses the possibility of creating new DHC indicators. • Discusses the trends in future DHC development.

[Display omitted] • Biopolymers act as a sustainable and green alternative in the food industry. • Active biopolymers help in the preservation and extends the shelf life of food. • Smart packaging conveys the real-time data of the food to the consumers. • Consumer awareness fuels the development of active and smart biopolymers. The improper disposal of petroleum-based plastics has been associated with detrimental environmental consequences, such as the proliferation of microplastic pollution and increased emissions of greenhouse gases (GHGs). Consequently, biopolymers have emerged as a highly regarded alternative due to their environmental-friendly attributes and versatile range of applications. In response to consumer demands for safer food options, sustainable packaging, and escalating environmental concerns, the food sector is increasingly adopting biopolymers. Further, in the recent decade, the usage of active or functional biopolymers has evolved into smart biopolymers that can transmit real-time data to consumers. This review covers key topics such as antimicrobial and biodegradable packaging, edible coatings and films, incorporation of scavengers and bioactive substances that prolong the shelf life and guard against moisture and microbial contamination. The paper also discusses the development of edible cutlery as a sustainable substitute for plastic, the encapsulation of bioactive substances within biopolymers, 3-D food printing for regulated nutrition delivery and thickening and gelling agents that improve food texture and stability. It also discusses the integration of smart polymer functions, demonstrating their importance in guaranteeing food safety and quality, such as biosensing, pH and gas detection, antibacterial characteristics, and time–temperature monitoring. By shedding light on market trends, future scope, and potentialities, this review aims to elucidate the prospects of utilizing biopolymers to address sustainability and quality concerns within the food industry effectively.

This paper proposes a set of digitalisation indicators focused on measuring the different digital capabilities and infrastructure of electricity distribution systems, as opposed to previous indicators which have mainly focused on performance and quality of service aspects. The indicators are classified according to the pillars of digitalisation: sensor and actuator, connectivity, data processing, and digital culture. They are use-case-agnostic and do not require a huge amount of information. In addition to this, three possible new applications of these indicators for distribution system operators and regulatory authorities are identified and discussed. The extensive use of these indicators in Europe could allow the development of fruitful collaborations between distribution system operators, allow the identification of cause–effect relations between grid performance and digital infrastructure, and improve the replicability of innovative smart grid solutions. However, this will only be possible if regulators promote the adoption of the proposed indicators and the dissemination of their results. • Smart grid indicators are required by European Directive 2019/944. • Indicators on sensors/actuators, connectivity, data processing, and digital culture. • Indicators to provide an overview of the distribution grid. • Indicators to study relation between performance and digital infrastructure. • Indicators to generate information for the replicability of solutions.

This paper presents the methodology developed to calculate the Self-Rescuing Index for communities downstream of mining tailings dams. An initial calculation formula was developed based on consultations with specialists in engineering, safety, geotechnology, geotechnics, geography, social work, and social sciences. This formula consisted of twenty-two indicators and five indices that make up the final index. The initial results were revised after a new round of consultation using the Delphi method, as well as considering the data available from official sources, Dam Break studies, and primary data collection from communities located in risk areas. The results were georeferenced, enabling a detailed analysis of people's location, their vulnerabilities, as well as of the territory, making a consistent geostatistical tool available for decision-making in managing disaster risks related to mining dams.

• This article is in reaction to the new Directive (EU) on the resilience of critical entities. • It was created using the Critical Entities Resilience Failure Indication tool (CERFI Tool). • The CERFI Tool connects threat knowledge and the resilience of critical entities. • The CERFI Tool contributes to improving the safety of energy and transport infrastructures. • The use case focuses on the assessment of a physical attack on an electricity substation. The adoption of the new Directive (EU) 2022/2557 on the resilience of critical entities has raised the question of how to assess the level of resilience of these entities in relation to current security threats. Until now, approaches have focused only on assessing the resilience of critical infrastructure elements. However, the new Directive exemplifies the need to pay attention not only to the element resilience, but also and more importantly to the resilience of their owners and operators, i.e., critical entities. Based on this fact, the authors of the article created a tool for Critical Entities Resilience Failure Indication (CERFI Tool). The essence of this tool is a probabilistic algorithm that predicts the relationship between the threat intensity and the protective part of critical entity resilience through indicators (to be created by the assessors themselves). The result of this prediction is an indication of the critical point of failure of the critical entity's resilience in phases of prevention and absorption of impacts. The CERFI Tool thus contributes to increasing the safety of technically oriented infrastructures, especially those of an energy and transport nature. The paper concludes with an example of the practical application of the developed tool on a selected critical entity in the energy sector. [ABSTRACT FROM AUTHOR]

• There is high consistency in the extent of land degradation. • There are consistent hydrothermal change characteristics in the land degradation hotspots area. Land degradation is a major impediment to achieving sustainable development. However, there is currently no harmonized global map of land degradation status and hotspots. This paper aims to obtain the status and hotspots map of global land degradation by multiple methods and indicators to give essential references for land degradation neutrality. The results show that there are significant differences in the distribution and degree of land degradation between the different methods and indicators. Validation through observation points reveals that most of the methods and indicators can reflect land degradation in arid and semi-arid areas, while there are suitable methods or indicators in tropical and high-latitude areas. The degree of degradation has a large difference after overlay analysis, which shows that there are shortcomings of different methods and indicators for monitoring the degree of land degradation. However, the overlay of land degradation extent displays a high consistency, reflecting the current state of global land degradation to a certain extent. These areas with high overlay value can be recognized as hotspots of land degradation. It is also found there are consistent water-energy change characteristics in the hotspot area, such as increased land surface temperature and air temperature and decreased soil moisture and precipitation. These results conclude that studies on the degree of land degradation need to be considered in an integrated manner about the regional background. The combination of multiple methods and indicators is recommended for land degradation extent studies in large areas. Comparison of different methods and indicators is important guidance for global land degradation research. Accelerating ecological monitoring and restoration of land degradation hotspots is the first step towards land degradation neutrality. [ABSTRACT FROM AUTHOR]

Despite their limitations as proxy measures, indicators can serve as leverage points in encouraging policy change. Facing the global urgency of climate change and increasingly recognizing the role of education in providing the social and political impetus for climate action, indicators on climate change education can help. However, despite the encompassing of climate change education in several Sustainable Development Goal (SDG) targets, the associated global indicators currently rely on country self-reported and otherwise inadequate data. This paper describes a collaborative process of developing publicly available third-party data sources to support more robust indicators of climate change education, including in relation to the SDGs. • Climate change education is closely intertwined with the Sustainable Development Goals, in particular target 4.7. • High quality indicators can be useful to support necessary policy change. • The few existing indicators that on climate change education are based on self-reported and otherwise inadequate data. • Collaboratively developed indicators based on third-party data offer a path to the development of more robust indicators.
