Humans are exposed to several chemical substances during their regular daily activities that can be harmful even in low quantities. Accounting for the mass of a given released chemical may not be appropriate for the assessment of its toxicological impact. To overcome the lack of a systemic perspective of mass-based assessments, methods such as the chemical footprint (ChF) are an alternative to account for a given chemical’s environmental and human toxicological impacts, a task that is considered essential in order to achieve the Agenda 2030 for sustainability. Among others, persistent organic pollutants (POP) should receive attention due to their high potential impact. Using the USEtox model to estimate indicators of human health impact, this study proposes an approach to calculate ChF for dioxins and furans and applies it to Brazil as a case study. The USEtox model quantifies human health impacts from the characterization of factors of a given chemical. Results show that ChF for dioxins and furans is approximately 620 DALY, representing a potential loss of 620 years of life in the Brazilian population. Social costs related to dioxins and furans emissions achieved USD 30 million, translating into monetary values not found in the existing literature. Besides highlighting the impacts of chemical emissions on the Brazilian population, this work contributes to the advances in methods for quantifying more appropriately such impacts beyond the exclusive use of mass units, in turn supporting sustainability-related public policies.

Purpose Students play an unequivocal role in sustainable universities as they are theorized to embody the mission of a sustainable university through a sustainable lifestyle and spread sustainability practices during their professional careers. Despite this, it is not well known how or why students come to embody a sustainable lifestyle. This study aims to better understand the relationship between happiness, academic achievement and sustainability behaviors among the student population in a Mexican higher education institution. Design/methodology/approach In a questionnaire study, engineering and psychology university students at a large public university in northwestern Mexico answered questions regarding their environmental sustainability behaviors, happiness and academic performance. A stratified random sampling technique was used to obtain the sample population that best represents the entire population. After chi-square tests, it was confirmed that the three variables were independent of one another. Therefore, a series of correspondence analyses were conducted to examine clusters or patterns that could indicate relationships among the three variables. Findings The main finding from this work was that the happiest and most academically astute participants were only slightly environmentally sustainable or not sustainable at all. The lack of environmental sustainability in students from one of the most top-rank sustainable universities in Mexico does not align with previous sustainability reports. External factors to the university, such as cultural values and extreme weather conditions, may have influenced students’ sustainability behaviors. Research limitations/implications As with any other questionnaire study, the provided data is subject to interpretation, judgment and bias. In addition, the environmental and happiness index used in this study are not free of criticizing, and some author had disputed its efficacy. Finally, this study’s findings did not determine any causality or directionality between any of the latent variables. However, causality and directionally between environmental sustainability-happiness and happiness-academic performance have to be found in both directions. Practical implications Despite the unsustainability of students in this study, this study has several contributions. First, it provides an evaluation of a sustainable university from the perspectives and behaviors of students. The views of students as they relate to the complexities and visions of a sustainable university have remained relatively underexamined. Second, these analyses point to specific sustainability-oriented challenges and inadvertent barriers (e.g. extreme weather patterns) toward the embodiment of a sustainable lifestyle. These challenges and barriers suggest that sustainable universities need to address the dynamic changes inherent in sustainable development. Finally, this study indicates that the link between happiness, academic performance and sustainability may be more complicated and driven by cultural and structural barriers. The issue of barriers, as they relate to sustainability behaviors, is highly relevant and presents important opportunities and questions for future research.

The United Nations Sustainable Development Goals emphasize the need to better understand and propose solutions for the growing demand for resources and the generation of waste by anthropic systems at any scale and intensity. Although it can be considered as secondary importance problem, hundreds of tons of green coconut shell residues annually generated in the Brazilian coastal cities are transported and dumped in landfills, wasting their energy potential and resulting in economic and environmental problems – this approach is known as take, make, disposal, or “linear” production model. This work proposes a “circular” model by using the biomass from green coconut shells generated by the cities of Baixada Santista region as a raw material for briquettes production. Technical-operational, environmental, and financial aspects are considered to assess the proposed “circular” model in comparison with the existing “linear” model. Results show that technical-operational aspects of the “circular” model are viable due to already existing technologies in the market that can be easily adapted for the purposes in converting green coconut shells into briquettes. The “circular” model proposed allows a reduction in greenhouse gases emission by ∼40 thousand tons year−1 when compared to the “linear” model, besides avoiding leachate generation. Furthermore, the 66% profitability, 195% rentability, and 6 months of investment payback suggest the financial viability of briquettes production. Together, all these indicators claim for public policies incentives and private investments to make the proposed “circular” model a reality, which is aligned with the objectives of 2030 agenda. RESUMO Os objetivos do desenvolvimento sustentável enfatizam a necessidade de melhor entender e propor soluções para a crescente demanda de recursos e geração de resíduos pelos sistemas antrópicos, em qualquer escala e intensidade. Embora em princípio possam ser considerados como um problema de menor importância, os resíduos de casca de coco verde gerados nas cidades litorâneas brasileiras são transportados e despejados em aterros sanitários, desperdiçando-se seu potencial energético e resultando em problemas econômicos e ambientais — conhecidos como modelo “linear” de gerenciamento. Este trabalho propõe um modelo “circular” com o uso das cascas de coco verde geradas pelos municípios da baixada santista como matéria-prima para a fabricação de briquetes. Aspectos técnico-operacionais, ambientais e financeiros são considerados para avaliar a o modelo circular de forma comparativa ao modelo linear existente. Os resultados mostram que os aspectos técnico-operacionais do modelo circular são consistentes, passíveis de serem implementados. Esta proposta possibilita a redução na emissão de gases de efeito estufa em 40 mil toneladas por ano quando comparada ao modelo linear, além de não gerar lixiviado. Adicionalmente, a lucratividade de 66%, a rentabilidade de 195% e o retorno sobre o investimento de seis meses evidenciam a viabilidade financeira deste modelo. Estes resultados sustentam a necessidade de políticas públicas e/ou investimentos privados para tornar o modelo circular proposto uma realidade, em busca de atingir os objetivos da agenda 2030.

Several regions have struggled to define and implement strategic priorities to ensure resource supply security and environmental, economic, and social sustainability. The circular economy is gaining more and more importance as one of the forms of transition towards a sustainable future that integrates, in a balanced way, economic performance, social inclusion, and environmental resilience, for the benefit of current and future generations. In light of the challenges of solving or avoiding future problems, the G20 bloc created proposals and action plans to support the transition towards a more circular economic model while at the same time fostering discussions on the implementation of the 2030 Agenda for Sustainable Development. Therefore, the main objective of this study is to monitor and compare the performance of 19 countries in the G20 bloc (the 20th member is the European Union) from 2000 to 2020 to assess their progress toward environmental, economic, and social sustainability supported by the CE principles. To achieve this objective, the five sectors sustainability model was used and was supported by goal programming as a multicriteria analysis tool generating a synthetic sustainability indicator to assist decision making. The results showed that the countries with the best overall sustainable performance (environmental, economic, and social) in 2020 were Canada (which also occupied the best position in 2000), Australia, Italy, the United Kingdom, and the United States, while Argentina, South Africa, India, Indonesia, and China showed lower sustainability. The results can serve as a reference for decision making by stakeholders in designing policies and incentives to encourage the adoption of the circular economy and boost economic development without compromising welfare or the environment.

Family farming is a lifestyle and agricultural base that has ensured food for the world’s growing population in addition to the family’s own subsistence. However, the intensification of production processes to primarily generate exportable surpluses is based on the constant input of industrial inputs of low local socioeconomic viability. This study aims to evaluate the sustainability of family farms and their impact on the adoption of homeopathy instead of traditional/conventional intensification techniques. The study was conducted at six family farms located in the Serrana Mesoregion, Santa Catarina, Brazil, and include farms were classified according to the management and representativeness of their agricultural activity, i.e., conventional grains-cattle, milk-grains, grains and diversified, and according to their ecological basis, i.e., agroecological and organic. To discuss the sustainability of the family farms that were evaluated, the of metrics emergy synthesis, ecotoxicity potential and socioeconomic indicators are used. The results indicate that conventional diversified property has the best overall performance with regard to sustainability, including emergy yield ratio (EYR 1.88), emergy investment ratio (EIR 1.13), return on assets (1.22), hourly income of work (36.6 BRL/h) and income sufficiency (3.3). Agroecological and organic properties have better performance in renewability (76% and 75%), environmental load (ELR = 0.32 and 0.34), sustainability (ESI = 4.78 and 3.5) and potential ecotoxicity (1.736 and 1.579 kg 1.4 DCB-eq/ha). The contribution of homeopathy in an alternative scenario results in a 19% reduction in nonrenewable flows in conventional management properties and a decrease of up to 91% in ecotoxicity in grain + cattle properties. Using homeopathy, the return on assets and profit margin can be increased by up to 43% and income per hour of work and income sufficiency can be increased by 20% and 16%, respectively. This study contributes to discussions about the importance of using homeopathic therapies as a viable strategy that can be used in strategic public policy plans to improve the sustainability of family farms.

Petrochemicals, which convert oil and gas into products such as plastics, are fundamental to modern societies. Chemists recognize their role in the design of materials and the adverse effects that these may have on the environment, preventing sustainable development. Several methodological frameworks and sustainability assessment approaches have been developed to evaluate the resources used in the petrochemical sector in terms of environmental costs. A combination of Life Cycle Assessment and Emergy Accounting - to assess the environmental support for resource use - is applied in this study of the PET production chain in Europe. The Unit Emergy Values of several intermediates are calculated or updated to facilitate discernment of the quality of energy used and the processes' efficiency. Several routes for synthesizing renewable para-xylene and ethylene glycol from biomass are discussed and confronted with the efforts focused on recycling and recovering the final product providing concurrently a procedure and a valuable data set for future CP actions. The results show that understanding the efficiencies changing across the production chain may help stakeholders make wise choices as to where and when interventions to promote a circular economy are most effective along a petrochemical production chain.

The world’s water resources are under pressure due to human activities. The challenges surrounding water resources management include enhancing long-term water security and minimizing undesirable economic, social, and environmental impacts, along with the production chain. Since water and wastewater treatment plants are designed to maintain and conserve freshwater provisioning services, understanding how they operate—prior to proposing options for sustainability—is of paramount importance. The diagnostic phase calls for scientifically-based, systemic, and more objective methods to provide information for decision-makers regarding strategic management of water resources. This work applied the FIVE SEctor SUstainability (5SEnSU) model to assess twenty major water and wastewater treatment companies (WWTC) in Brazil, to quantify sustainability levels that allowed ranking procedures, and to establish benchmarks for improvements. On a comparative basis, the results identified the top-three sustainable companies—CORSAN, CASAN, and SANEPAR—which should be considered as examples of best practices. Specifically, the following best-ranked companies in each sector within 5SEnSU should be used as benchmark patterns for more oriented best practices: SANEAGO, sector 1; AGESPISA, sector 2; CORSAN, sector 3; CASAL, sector 4; MA, sector 5. This work contributes toward the advancement of sustainability assessment modeling in human-managed systems (applied in WWTCs in this present study) from systemic- and epistemologically-rooted approaches, avoiding shortcomings and misleading discussions on the sustainability issue. Quantifying sustainability of WWTCs using the 5SEnSU model allows for the identification of those sectors/indicators that require immediate cleaner production practices by decision-makers, to improve overall sustainability, as well as to identify which companies are more aligned with the requirements of UN SDGs. The decision-makers would be able to visualize balanced or unbalanced relationships among all sectors and propose actions that would improve the performance in a given sector, realizing what effects a given action would cause in the other sectors of the system.

The current world environmental challenges claim for actions towards a sustainable development. Humans demand huge amount of resources to support the chosen development pattern, and returns concentrated human-waste to be diluted by nature, making this relationship unbalanced. This situation becomes worse when the resources extracted are beyond their own natural capacity of replenishment, which jeopardizes the resources availability and all social related issues as described by the 17 sustainable development goals. There is a common sense about the need of rethinking about the world we want for today and future generations, and for this task, looking for more sustainable production systems is an important step to feed policy makers with reliable scientific data to support better-oriented public policies. This special issue brings research show cases focused on themes discussed during the 8th and 9th International Workshop Advances in Cleaner Production, including cleaner production technologies, resources efficiency, environmental management, ecological modeling and business sustainability report. The main goal of this paper collection is to collaborate for the advances of cleaner production for the most different scales as an important approach to achieve the needed sustainable development.

Water resources are under pressure because of human activities. Its management faces the challenge of enhancing long-term water security while minimizing undesirable economic, social, and environmental impacts along with its production chain. Since water and wastewater treatment plants are designed to maintain and conserve freshwater provisioning services, it is paramount to understand how it operates before proposing options for sustainability. At this point, the diagnosis phase claims for methods scientifically-based, systemic, and more objective to provide information for decision-makers towards strategic management of water resources. This work applies the five-sector sustainability model (5SenSu) to assess Brazil's twenty major water and wastewater treatment companies (WWTC) to quantify their sustainability levels that allow ranking procedures and the establishment of benchmarks for improvements. Under comparative basis, results identified the top-three sustainable companies, CORSAN, CASAN, and SANEPAR, which should be considered examples of best practices. Specifically, the following best-ranked companies in each sector within 5SenSu should be used as benchmark patterns for more oriented best practices: SANEAGO, sector 1; AGESISA, sector 2; CORSAN, sector 3; CASAL, sector 4; MA, sector 5. This work contributes to the advancement in modeling sustainability assessment of human-managed systems (applied in WWTCs in this present study) from a systemic and epistemologically rooted approach, avoiding shortcomings and misleading discussions on the sustainability issue. Quantifying sustainability of WWTCS from 5SenSu allows the identification of those sectors/indicators that requires immediate cleaner production practices by decision-makers to improve overall sustainability, besides identifying those companies more aligned with the requirements of UN SDGs.

No. of bitstreams: 0 Previous issue date: 2022-01-10 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Aquaponics is a food production system that aims higher sustainability by integrating advantages gained from aquaculture and hydroponic production. Aquaponics aims to mimic the biological process that happens in the natural environment in a controlled production system. As it can be applied to small scales, aquaponics is considered an important alternative for urban regions, which have low availability of agricultural land and water resources. Furthermore, the advantage is that it is located close to final consumers. Aquaponics has been labeled as an environmentally friendly food production system, but its demand for energy and materials cast doubt on its sustainability. A systemic understanding of aquaponics production systems is needed to determine the magnitude and balance between its potentialities and constraints, in which emergy synthesis appears as a powerful tool for this purpose. This study applies emergy synthesis to assess the sustainability of two different (scale and marketable products) urban aquaponics farms in Brazil, but differently from other emergy studies, ecosystem services and disservices are included in the analysis as an attempt to represent the system performance holistically. Results show that the type of materials used in aquaponics infrastructures has the highest influence on total emergy demand. Surprisingly, electricity and fish feed showed a low influence on the total emergy, reinforcing the idea that aquaponics systems have a more efficiency feeding management than traditional aquaculture systems. Besides producing vegetables and fish, the inclusion of ecosystem services highlights the importance of aquaponics for educational and tourism purposes. Finally, the obtained indicators from modeling scenarios revealed that replacing the water source and some materials deserves priority attention to increase the sustainability of urban aquaponics farms.

The sustainability of such systems has not been assessed and it can be improved based on suitable scientific analyses. In the present study, we apply the emergy synthesis to assess the sustainability of lambari aquaculture, used as a model of freshwater pond monoculture in Brazil, to identify the key practices, and to propose changes to improve them towards sustainability. As a study model, nine semi-intensive lambari farms operating at three levels of management were evaluated: low (LC), moderate (MC) and high (HC) control. Results showed that the main inputs for LC were services (27–46%), feed (7–39%) and water (15–21%), while for the MC and HC farms, they were feed (35–49% and 17–48%, respectively) and services (33–39% and 26– 36%, respectively). All farms required more than 60% of their emergy from purchased inputs, resulting in low emergy sustainability index (ESI = 0.1–0.5). Increasing juvenile productivity, using superficial water instead of springwater, controlling pond fertilization and replacing animal protein in diet composition by vegetable sources can lead systems to higher efficiency and resilience, increasing sustainability.

During the Covid-19 pandemic peak period, changes were devised for society to adapt to the new lifestyle without affecting its development. Among others, education was one of the most affected areas in this period due to the mandatory social distancing. Education institutions adapted to this new scenario by switching from face-to-face to remote teaching, which brings advantages and disadvantages. To better understand this new teaching-learning pedagogical approach, it is important to listen to those intimately connected in this process: professors and students. Since they provide personal and subjective opinions connected to their own cultures, perceptions, and other very personal variables, assessing their opinions requires a different approach based on unusual logics, in which the paraconsistent logic appears as a potential tool. This research aims to apply the paraconsistent annotated evidential logic Eτ (PAEL) in the opinion of students and professors of an engineering post-graduate program in the state of São Paulo to evaluate whether or not to return to face-to-face academic activities at the university, after the Covid-19 pandemic. A survey was applied to a sample of professors and students, embracing nine variables related to teaching, research, economics, time, and efficiency. Results show that, although research and time indicators are located within the ‘truth’ region of the cartesian unitary square, the barycenter is in the 'almost true' region, indicating an inconclusive response as to whether or not to return to face-to-face academic activities. This study contributes to discussions about the newly imposed after Covid-19-scenario towards more effective pedagogical approaches.

Thirty years ago, the systems ecologist Howard T. Odum introduced the concept of transformity, which is a thermodynamic measure of quality within the trial and error evolutionary dynamics of ecosystems, namely an indicator of rank in the hierarchical system structure of the biosphere. Based on a global database of individual processes and whole economies, this paper extends, refines, and updates Odum's idea, demonstrating the strength of the postulated relation. In particular, an inverse linear logarithmic relationship is shown to hold between resource quantity (exergy) and quality (emergy), which is the result of an overall energetic efficiency characteristic of energy transformation processes of the biosphere. This relation extends from natural renewable energy sources to human information (including global internet data flows) and know-how embedded in national economies, thus identifying a consistent theory of hierarchical organization of the biosphere grounded in energetics and ultimately setting constraints to illusions of unlimited growth., Graphical abstract, Public summary • A well-defined representation of the self-organizing hierarchical structure of biosphere is provided • Additional evidence shows transformation processes result in work potentials (exergy) of differing quality depending on placement within the hierarchy • Expansion of higher levels of organization (i.e., information) are constrained by availability of resources requiring investments of nearly 20,000 times the energy invested at the top of the biosphere hierarchy • The understanding of energy constrains may lead to better resource management and economic policy perspectives

The pressure imposed by human-dominated systems on the natural environment and the search for more balanced social systems are current concerns worldwide. Among scales of attention and shared responsibilities, companies are also in the radar of and interested in to be more sustainable. An efficient way in disclosing information on companies' sustainability is through sustainability reports, such as the global reporting initiative (GRI) framework. Although recognized as an important alternative, the GRI is receiving criticisms about its ability in accurately express the meaning of sustainability. This work applies the paraconsistent annotated evidential logic (PAEL) on opinions of experts in the sustainability theme to verify whether the GRI indicators are aligned to the concept of `strong' sustainability. A survey applied to twenty-two experts from different field areas, backgrounds and work experiences on sustainability-related issues provided their beliefs and disbeliefs, in a quantitative way, about the ability of each of the 91 GRI indicators in expressing sustainability. Results show high dispersion (coefficient of variation $>$30%) among the experts opinions for 77 of the GRI indicators, in which the social category appears with the worst performance with its total 48 indicators with high dispersion. This is an indicative of different understandings by experts about the meaning of sustainability concept and/or the meaning and reach of GRI indicators in achieving sustainability. The PAEL reports that all three categories (economic, environmental and social) fall into the `paracomplete' region of the Cartesian unitary square's graph, indicating an inconclusive result about whether these three categories are able to capture and/or express the concept of strong sustainability. The overall performance (barycenter with beliefs of $\mu =0.26$ and disbeliefs of $\lambda =0.17$) also fall into the paracomplete region, rejecting the initial hypothesis that GRI may show strong sustainability. Recognizing the increasing importance of sustainability reports, this work contributes in identifying and suggesting improvements to the GRI developers on indicators that may better represent the strong sustainability and achieve its main goals. GRI's framework should be based on a clear sustainability model and provide through a simple, fast and understandable way, information about the purposes of each indicator. Focus for improvements should be especially directed to: EC4-6; EN18, 20, 21 and 34; LA2, 4, 5, 7, 8, 11, 12, 14; SO3-8, 11; PR1-5, 7-9; HR3, 8-10.

Increasing economic and population growth has put immense pressure on energy, water and land resources to satisfy national and supra-national demand. Through trade, a large proportion of such a demand is fulfilled. With trade as one of its key priorities, the China Belt and Road Initiative is a long-term transcontinental investment program. The initiative gained significant attention due to greater opportunities for economic development, large population and different levels of resource availability. The nexus approach has appeared as a new viewpoint in discussions on balancing the competing sectoral demands. However, following years of work, constraints exist in the scope and focus of studies. The newly developed multi-regional input–output (MRIO) models covering the world’s economy and its use of resources permit a comprehensive analysis of resource usage by production and consumption at different levels, and bring more knowledge about resource nexus problems. Using the MRIO model, this work simultaneously tracks energy, water and land use flows and investigates the transnational resource nexus. A nexus strength indicator is proposed which depends on ternary diagrams to grade countries based on their combined resources’ use and sectoral weighting. Equal sectoral weighting is assigned. The analysis presented a sectorally balanced nexus approach. Findings support existing work by recognizing energy, water and land as the robust transnational connections, from both production and consumption points of view. Resource nexus issues differ from country to country owing to inequalities in industrial set-up, preferences in economic policy and resource endowments. The paper outlines how key resource nexus problems can be identified and prioritized in view of alternative and often opposing interests.

An ecological footprint is an accounting tool that reports the balance between resource supply and demand to assess environmental sustainability. Among the many available indicators of social progress, happiness reflects how a person feels about their quality of life. We combined these two approaches to assess the ecological efficiency of social performance in the low-income community of Felicidade, in São Paulo, Brazil, in 2019. We assessed the ecological footprint and gross domestic happiness (GDH) through questionnaires. We found that the community has a lower environmental footprint than higher-income communities in Brazil. However, the per capita ecological footprint in the community is still above what is available per person globally. We found that the community has a high level of life satisfaction (GDH = 0.86) and that the main contributor to happiness is health, time use, psychological wellbeing, education, good governance, and community vitality. The results suggest that other contributors unrelated to income are more robust determinants of happiness. In Brazil, despite higher footprints characterizing higher-income communities, further efforts in low-income communities are needed to reduce environmental footprints, ensure dignified income, and nurture the underlying conditions for high levels of happiness and social capital.

Sustainability assessment is a fundamental step to support decisions towards sustainable development, and several procedures to assess the sustainability of antrophic production systems have been suggested. However, most of them lack a scientific-based construct supporting their conceptual model of sustainability, which usually results in a choice of indicator(s) without criterion that can best represent a fraction of the larger and deeper concept of sustainability. This work proposes a novel framework, named Sustainability Assessment Procedure for Operations and Production Processes (SUAPRO), supported by the PDCA four-step management method (plan, do, check, and act) and the five sectors sustainability (5SEnSU) model. Grounded on scientific bases, SUAPRO provides the steps for a sustainability assessment, including its contextualization (objectives, functional unit, boundaries, energy diagram), the choice of indicators based on the 5SEnSU model, the quantification step including goal programming as a multicriteria tool, and conclude the first cycle with a sensitivity analysis. To illustrate an application of SUAPRO, the road and railroad transportation options for soybean in Brazil are considered as a case study. Results show that the railroad mode has better performance as for the Sustainability Synthetic Indicator (SSIS of 3.6 ± 0.4) than the road mode (SSIS of 4.0 ± 0.3). Towards a SSIS improvement, the sensitivity analysis highlights that public policies or even private actions should be mainly focused on reducing the emergy invested in the railroad system, while the road transportation option claims effort in reducing its global warming and acidification potentials. SUAPRO is the main contribution in this work, as it tries to overcome shortcomings as usually found in scientific papers aiming to assess the sustainability of antrophic systems. The subjectivity inherent in any multicriteria method is present as the main limitation, thus all criteria used in choosing weights must be clearly presented.

The decision-making process towards sustainability is usually based on quantitative indicators, and becomes more complex the more indicators are considered. The lack of a clear criterion (i.e. a conceptual model of sustainability) supporting the choice of one indicator rather than others creates doubts about the real attainments of such studies. The holistic-based approach in choosing indicators to express sustainability claims for a multicriteria perspective. This work proposes a sustainability assessment tool based on the FIVE SEctor SUstainability (5SEnSU) model that is capable to show the relationships between humans and the natural environment, and the use of goal programming as a multicriteria method. The advantages of the proposed tool are based on clear criteria in choosing indicators supported by the 5SEnSU model, which recognizes the double functions (as a donor and receiver) of natural environment and society, as well the application of goal programming to obtain an easy-to-understand final indicator: the sustainability synthetic indicator of systems (SSIS). The countries that form Mercosur economic bloc were used as a case study to illustrate the application of the proposed model. Results have shown that Uruguay holds the highest sustainability performance among all Mercosur countries, although still demanding efforts from public policies to improve its national happiness level (K52 indicator), employment rate (K41 indicator) and total emergy flow per capita (K12 indicator). Instead of using a single criterion in choosing indicators, this work provides a scientific-based tool in choosing, calculating, and supporting discussions on the sustainability of production systems under a more holistic perspective.
