Addressing this gap is vital for our future well-being. Hence, more research is needed on whether and how companies translate broader CE discourses into their future visions. This study employed frame analysis to investigate how the CE's meaning and goals are being envisioned and shaped in companies' external communication to advance their future goals. Drawing empirical insights from documents focused on 41 Finnish self-declared front-runner CE companies from various industries, the paper contributes to current CE literature in two ways. First, five distinct future vision frames were identified – technological utopia, outsourcing circularity, business-as-usual, market leader, and systemic change – that demonstrate how self-described front-runner companies communicated circularity to their stakeholders. Second, the study demonstrates how company-level future visions align with or differ from macro-level CE visions. The study found that even self-described frontrunner CE companies were reluctant to align with strong sustainability in their framing, limiting the transformative potential of CE in business context. The findings have implications for managers regarding how they can assess their future visions from the perspective of weak or strong sustainability.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"7 ","pages":"Article 100066"},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791624000125/pdfft?md5=f9f71219890c91b21fb8dc03aee62c1c&pid=1-s2.0-S2666791624000125-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141607387","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}

Recognizing that gender equality must be introduced in Agenda (2030), this paper intends to examine the impact of well-established macroeconomic and socioeconomic variables in existing literature alongside the role of women in governance. More specifically, this study uses panel data analysis to investigate the understanding of the effects of economic growth, renewable energy, human capital, female representation in parliaments, and environmental regulation on carbon dioxide (CO₂) emissions in 20 European countries from 2004 to 2018. Empirically, the study employs several econometric tests and approaches. Findings partially confirm the Environmental Kuznets Curve (EKC) hypothesis, while renewable energy and tertiary education enhance sustainability. Environmental regulation is significant for policymakers as it decreases pollution. The role of women in parliaments, which has been scarcely examined in existing literature, appears to be beneficial for the prosperity of EU societies. All empirical findings leave ample room for further discussion among European stakeholders and policymakers, emphasizing the importance of female participation in governance.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"7 ","pages":"Article 100065"},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791624000113/pdfft?md5=36229c248307d548b1dd21c4d76b70de&pid=1-s2.0-S2666791624000113-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141623794","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}

A reliable sustainability assessment must be carried out to improve environmental and social sustainability performance for whole systems. It is necessary to show how a system of interest at any scale should (and can) improve sustainability performance. An examination of the literature on sustainability assessment highlights a lack of a systems perspective in most sustainability assessment frameworks. The aim of this paper is, therefore, to provide a framework that enables an assessment of environmental and social sustainability performance, taking systemic aspects into account. This assessment framework is based on a definition of first- and second-order sustainability performance. The former focuses on narrow efficiency issues, while second-order sustainability performance focuses on systemic effectiveness and covers sustainability impacts on society and nature. Improving the first-order level (narrow perspective) will not automatically lead to an improved second-order sustainability performance (systemic perspective). Thus, systemic effectiveness is not automatically increased in the case of first-order sustainability performance. Therefore, three essential dimensions have been identified and combined in an assessment framework, i.e., the dimension of scale, the decision horizon, and sustainability principles. The conceptualized assessment framework allows to analyze whether an action of a system of interest (e.g., corporate action, any process, project, or policy) contributes to global sustainable development.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"7 ","pages":"Article 100064"},"PeriodicalIF":0.0,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791624000101/pdfft?md5=400879901333583d0f7eb74354caaa20&pid=1-s2.0-S2666791624000101-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141482055","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}

Ecoibéria and Logoplaste provided the majority of the required data, and three functional units were considered. The first one was the production of 1 kg of PET, the second was the production of different water bottles, and finally, the third one was the consumption of 2 l of water with different water bottles. As a result, it was first observed that the production of rPET flake in comparison to vPET reduces, on average, 79% of the impacts, and rPET pellet reduces 10% of the impacts. Secondly, in the production of the different water bottles, Option A, the single-use bottle, presented the lowest environmental impacts in almost all categories. Finally, when taking into account the reusable factor, the use of single-use bottles presented the higher environmental impact in all categories, probably because of the dilution of the environmental impacts associated with the production of heavier and robust reusable bottles by the multiple times of uses of these bottles.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"6 ","pages":"Article 100061"},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666791624000071/pdfft?md5=fe807b190d05f709f2de0d727c364051&pid=1-s2.0-S2666791624000071-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140160913","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}

Developing economies could possess significant potential for implementing CE principles to attain sustainability, particularly in the CI. However, achieving this would require professionals in the CI to adopt some key competencies that should propel success in circular construction. Therefore, this study aims to identify the key competencies required by professionals in the CI to attain circular construction using Ghana as a case study. A quantitative research approach and purposive sampling technique were adopted. After an extensive literature review which showed several key competencies, a cross-sectional survey was conducted among five large construction firms and fifty-two responses from experienced professionals in the industry were obtained. Relative importance index and principal component factor analysis (PCFA) were adopted to evaluate the obtained data. Key significant competency skills for construction professionals to propel circular construction were identified such as specification writing for components and materials, designing for multiple-use cycles, and designing for near-zero energy buildings, among others. Three components were extracted from the PCFA which served as the guidelines for enhancing the competency skills of construction professionals namely, implementing sustainable circular practices, embracing sustainable operations management techniques, and adopting sustainable design principles. In addition, to enhance its practical implications, a competency implementation framework was also developed for construction professionals of developing economies to propel the adoption and evaluation of their competency skills toward circular construction.</p></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"6 ","pages":"Article 100060"},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266679162400006X/pdfft?md5=8d3bf165714fcf5dcf40a1b94b8d01aa&pid=1-s2.0-S266679162400006X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140180446","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}

Environmental extensions in the input-output analysis are designed from the user side perspective, focusing only on commercial energy supply and use. This study introduced emergy-evaluated supply-extended and use-extended carbon footprint models for Vienna and compared their empirical and conceptual implications. Emergy-evaluated footprints of Vienna's urban consumption were estimated by combining industrial and systems ecology approaches as per the research question, based on previous investigations of GHG emissions and energy supply- and use-extensions. Results showed that the ranking of footprints of final product categories is sensitive to the evaluation method, with products of extractive and manufacturing industries differing by more than 10% depending on whether emergy or carbon evaluation is chosen. The emergy-based comparison further reveals that for products of extractive industries, the difference between use and supply extension results can be more than 20% as opposed to carbon-based comparison with the difference between supply and use extension results for services not even amounting to 5%. Future studies could address the over-estimation of direct energy supply to the economy, under-estimation of product and service, inconsistency in standard use-extension design, and challenges in assembling emergy-evaluated supply and use extensions.

Utilizing a dataset from a survey of Norwegian firms in 2020, the results of econometric modelling based on factor analysis of firm perception, showed that firms that introduced product/service eco-innovations, or process eco-innovations during COVID-19 were significantly positively affected by the pandemic compared to other firms. In addition, these firms significantly introduced more innovations in other areas of operations as a direct consequence of the pandemic. However, the results also showed that firms that introduced product/service eco-innovations were also more negatively affected by the pandemic.

The literature review was based on 38 journal papers selected out of 3578 search results with an application of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flow chart methodology. A qualitative content analysis was used to identify and explore the main concepts and variables to evaluate the content of the articles selected by SLR. The results showed three main categories to be systematically measured to understand their impact: (i) capacity building, (ii) affective domain, and (iii) career readiness. Capacity building requires measuring students' sustainability knowledge, competence, and skill levels. The affective domain evaluates changes in students' perceptions, attitudes, and behaviours identified as affective learning outcomes for sustainability. Career readiness assesses a student's level of preparation for the workplace. These variables/constructs informed the development of a framework to measure the impact of student KE for sustainability in a systematic and comprehensive way. The proposed framework is the study's main contribution, supporting measuring the impact of student knowledge exchange for sustainability.
