Currently, 56.2% of the world's population lives in cities, accounting for 80% of the global GDP. It is projected that the current trend for world economic growth complemented by population growth and migration will continue affecting the resource production and consumption in cities and the impact this has on other urban areas. Here, we developed a new model approach that combines emergy input-output tables with ecological network analysis to investigate urban metabolism generally, and applied it to Vienna, Austria. This novel approach allows researchers to study the hierarchy of sectors and functional relationships along all possible metabolic paths of ecological and socio-economic flows exchanging in an urban economy and between the urban economy and its environment. Then, using system-level analyses (flow and contribution analyses) we determined the status of the system components. Finally, the critical components responsible for the status (distribution structure of each industry) and emergy consumption of the other sectors were identified using pairwise control and utility analyses. The results showed that the “agriculture, forestry and fishing” and “mining and quarrying” sectors had the lowest ability to receive financial inputs from the other sectors, reflecting a shortage of agricultural and mining products to meet consumers' demand. Moreover, “agriculture, forestry and fishing” had the highest energy dependence on the other sectors, indicating the lack of self-sufficiency in energy use and the inability of this sector to deliver energy effectively to consuming sectors. This also implies the importance of this sector in achieving the energy efficiency improvement and economic development goals for consumer cities. This work contributes to the existing literature on ecological network analysis via an introduction of the two-step approach that combines the diagnosis of low activity components in the system taken from traditional ecological network analysis with the novel identification of components behind the low activity of the other components. In addition, direct and indirect control, and indirect utility analysis were introduced for the analysis of the impact of the direct energy and indirect pairwise economic control and relational interactions of sectors in cities. Finally, this work explored the inner workings of the service part of the urban economy to reveal the role each tertiary sector plays in the development of primary and secondary sectors of an urban economy. The model developed in this study will provide support for city managers and policymakers to guide resource consumption towards an efficient and sustainable urban metabolic system worldwide.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"3 ","pages":"Article 100019"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791622000173/pdfft?md5=5be0d163ab05ba52dfd618005c8676ff&pid=1-s2.0-S2666791622000173-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75968458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time series data from 1990 to 2020 were utilized by applying the Dynamic Ordinary Least Squares method. The empirical findings revealed that a 1% increase in economic growth and fossil fuel energy use will increase carbon dioxide emissions by 0.36% and 0.67% in Indonesia. Conversely, a 1% increase in renewable energy use, technological innovation, agricultural productivity, and the forested area may lead to carbon dioxide emissions reduction by 0.11%, 0.07%, 0.24%, and 2.87%, respectively in the long run.

In order to tackle these global problems, fundamental changes in consumption and production processes are needed. The steel industry is one of the main emitters of CO₂ and changes in production processes bear a potential for climate change mitigation. Sustainability assessments often focus on the environmental dimension, while social impacts associated with such changes remain under-researched. The present study examines potential social impacts of production changes (bio-economy transition) in a steel mill in Belgium using a multi-regional input-output (MRIO) analysis. Within this paper three indicators are presented: workers' compensation, employment and vulnerable employment. The results show that the demand for labour in Belgium increases in the scenario studied, while reductions in employment and compensation are to be expected for the majority of other regions. This emphasizes that such transitions can have both positive and negative impacts and that a ‘big picture’ is needed. Improvements in one aspect (e.g., environment) can lead to negative impacts in another (e.g., social), resulting in so-called sustainability trade-offs. It is crucial to consider impact dimensions in an integrated manner to enable the identification and discussion of sustainability trade-offs of transition pathways.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"3 ","pages":"Article 100011"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791622000094/pdfft?md5=9b6d1f56836f8a7341b15906af5daeaf&pid=1-s2.0-S2666791622000094-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91637020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper contributes to the literature by using a systems approach to argue for a wider view, not only for the full range of deleterious effects of urban transport in a given city itself, but also for its impact on possibly distant locations that supply transport inputs and receive its waste products. The paper uses the published literature to first examine the various adverse effects of urban travel, and then to critically evaluate the proposed technology-based solutions. The main finding is that all these solutions are found wanting to some extent, especially given the limited time frame available; hence, for urban sustainability, large travel reductions are thus needed. It then looks at a very different approach: reductions in urban vehicular travel, particularly by car. Four approaches considered (changing urban land-use, reducing private vehicle travel convenience, introducing carbon taxes, using information technology as a travel substitute), This paper concludes that various measures for decreasing the convenience of car travel, such as by cutting speed limits and parking spaces, as being the most equitable in OECD cities, and potentially capable of rapid implementation.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"3 ","pages":"Article 100010"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791622000082/pdfft?md5=513607a4843ca6ab2f4c7cfdee38bea0&pid=1-s2.0-S2666791622000082-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91637013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these are notoriously difficult to obtain in an authentic version: local values require some interpretation by the researchers trying to define them, but this modifies them unacceptably. In this work we use a transdisciplinary perspective, by holding fast to the need for well-defined outcomes of perceptions but by obtaining them via a humanities-based process, named <em>WeValue InSitu</em>, of tacit-to-explicit crystallization of shared values-in-action. Here we innovate and demonstrate the approach of following that crystallization process immediately with a carefully-designed focus group discussion about climate change impacts on their life in the city. The result is a set of clear articulations with respect to life values, such that nuances and linkages between perceptions and values are retained, and across groups is a saturation and consistency that reflects the city (Shanghai) context. We find a conceptual model emerges for the residents: a) they have surprising awareness of climate change but did not think it's impacts so severe or urgent; b) some impacts concern them but they consider Shanghai to be the best place to live, because of its resources and good governance; c) they consider responsibility to be jointly individual and collective with the government; d) they expect clear and transparent communication from the government for collective action. These research outcomes are significant because there is currently no other efficient method to produce such useful results which are also demonstrably authentic: results which indicate not only future policy pathways but the current situation in detail. As the WeValue InSitu method is already shown to be transferable, this approach should now be systematically applied in comparative studies in different cities to determine its scalability, and to academic fields with similar research gaps such as ecosystem services and urban design.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"3 ","pages":"Article 100018"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791622000161/pdfft?md5=c9e89034d0667828167303ee10b03786&pid=1-s2.0-S2666791622000161-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78398795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need for decentralising water management becomes relevant, and vegetated roofs are internationally known to be able to assist in locally retaining and detaining stormwater. For these Nature-based Solutions to be effective, there must be science-based standardisation, supporting decision-makers towards effective public policy-making based on hydrological performance. However, this performance should be associated with local environmental conditions, and continental-size countries such as Brazil can have a large variety of climates. At the same time, Brazil lacks a comprehensive review associating experimental results with climatic classifications. In this sense, the present work aims at reviewing the experimental research undertaken in Brazil and synthesising its rainwater retention outcomes associating it to the Köppen-Geiger climate classification. To accomplish this task, the Rational Method is used to extract and conform data from 34 records involving internationally and nationally published works as well as grey literature. Results of this work present to national researchers not only gaps but important trends, generating further innovative opportunities for work, and present to international researchers an accessible and georeferenced bulk of data on vegetated roofs' hydrological performance in Brazil with the highest possible resolution. It was found that semi-arid climates had the best average rainwater retention rates (0.79), followed by subtropical (0.54–0.72), and the tropical climates had the lowest (0.55–0.69). The work concludes that vegetated roofs have a positive hydrological performance throughout Brazil. However, further work is needed to quantify the hydrological influence of a range of different structural and environmental factors that modify the roofs' performance. It is also shown that climates, particularly outside the financial centres of Brazil, lack data and hence need further investigation and experimental research.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"3 ","pages":"Article 100013"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791622000112/pdfft?md5=57c9c6f4662502f7c2482f9e4031ba37&pid=1-s2.0-S2666791622000112-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85014440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to evaluate how adopting sustainable practices can affect economic performance in developing countries within the context of Jordanian manufacturing companies. Based on existing literature, a questionnaire was developed covering aspects of sustainability in internal and external supply chain practices, SSCM drivers, and company performance. A total of 92 responses were analyzed to test the proposed hypotheses using regression analyses to test the single-variable hypotheses, and structural equation modeling to test the multivariate hypotheses. The results show that the adoption of SSCM practices is still in its initial stages for Jordanian manufacturers. Sustainability awareness is quite low, and Jordanian companies mostly do not seem to consider the environmental impacts of their manufacturing operations. The results also show a difference between manufacturing types: process industries were less likely to adopt SSCM practices voluntarily, while discrete industries were more likely to do so. Finally, for Jordanian manufacturers to compete in international markets, they should take further steps toward adopting sustainability. To enhance the investment potential of multinational companies, Jordan should take the advantages of the industrial parks/estates and adopt regulations that force manufacturers to adopt sustainability practices under external pressure.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"2 ","pages":"Article 100005"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791622000033/pdfft?md5=4cc27ff6343261c5ce4cdd419dfc5cbc&pid=1-s2.0-S2666791622000033-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73623309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
