Procurement functions at the intersection of construction supply chains, managing design, purchasing, and material sourcing activities. Effective information sharing both within and between organisations is essential for embedding circular economy principles into procurement processes. This paper adopts a systematic literature review approach to identify and synthesise research on information sharing in circular procurement. Descriptive analysis outlines the research trends, theoretical and methodological orientations, and geographical distribution of studies, while synthesis categorises barriers and enablers of information sharing across micro, meso, and macro-organisational levels. Additionally, circular economy-related information and knowledge management activities, such as creation, dissemination, and application, are mapped against stages of the strategic procurement process and the Royal Institute of British Architects Plan of Work, strengthening the study's relevance to construction practice. By integrating fragmented yet expanding bodies of literature, the paper provides a comprehensive understanding of how circular economy information and knowledge management intersect with procurement in construction. It offers a construction-specific framework that embeds circularity throughout the procurement lifecycle, with support from the Resource-Based View and Institutional theory and also identifies key organisational enablers and barriers. The review also highlights limited empirical and theoretical integration in current research and recommends future studies that apply behavioural and organisational theories to explore knowledge-sharing dynamics, examine policy impacts, and assess the role of technology and skills development in advancing circular procurement.</div></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"10 ","pages":"Article 100134"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addressed these gaps by developing an LCA-based calculation criterion designed to integrate multiple parameters using device-level data. The criterion is specifically tailored to provisioning scenarios targeting digitally excluded communities and was partially applied using a Dataset and lifespans of 710 refurbished devices from the eReuse initiative in Spain. Three provisioning scenarios (single user, two users with reuse, two users with new devices) were evaluated for Spain and extrapolated to South Africa and Sweden with contrasting electricity mixes to quantify the influence of energy in use. Reuse proved more advantageous than supplying new devices in terms of GWP per hour of digital access, and a one-at-a-time sensitivity analysis showed that the magnitude of this benefit is highly sensitive to device lifespans and electricity emission factors. Future integration of digital product information into LCA is expected to enhance the precision of sustainability indicators used to inform policy.</div></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"10 ","pages":"Article 100123"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145694809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses the problem that people overestimate their knowledge about climate change, which may distort how they respond to communication efforts. The main aim of this research is to examine how overconfidence shapes the perception and evaluation of climate-related messages. To investigate this, an eye-tracking experiment with 98 participants was conducted, comparing responses to a website containing either strong or weak climate-related signals. The results show that strong climate change signals significantly impact visual attention (i.e., lower attention to image but higher attention to text), and increase attitudes towards the communication, message effectiveness and positive word-of-mouth. By contrast, individuals who overestimate their climate knowledge pay higher attention to the text if signals are weak. When exposed to strong signals, overconfident individuals exhibit higher levels of reactance, which subsequently reduces both message effectiveness and word-of-mouth. Overall, the study concludes that climate communication strategies should be tailored to individuals’ perceived knowledge to avoid unintended resistance and improve communication impact.</div></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"10 ","pages":"Article 100129"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146090162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of bio-based materials, for example, is becoming increasingly relevant in the field of automotive logistics and factory equipment, particularly against the backdrop of global sustainability strategies pursued by automotive manufacturers. Although prior studies have demonstrated environmental advantages, there is still no consistent assessment approach that takes into account the specific requirements of car body construction systems and that systematically maps the influence of bound biogenic carbon. Life cycle analyses use different calculation methods to evaluate the environmental impact of bio-based materials in the context of bound biogenic carbon. This article closes this research gap by proposing a specific approach to the environmental assessment of car body construction systems using renewable raw materials. This approach can be applied across industries to factory equipment. The aim is to quantify the environmental effectiveness of material substitution in an industrial environment in a transparent and reliable manner using the presented approach, based on a case study of a car body construction plant. The study goes beyond the technical and economic dimensions and focuses on the assessment of environmental sustainability. The results of the case study show that the use of renewable raw materials is an effective method of reducing environmental impact and that the proposed assessment approach has proven to be feasible. The treatment of biogenic carbon in the assessment has a significant influence on the result.

However, public acceptance of WtE remains a significant challenge, particularly in rapidly urbanizing regions of the Global South. Although extensive international research has explored the technological and environmental aspects of WtE, a notable research gap persists regarding the interplay of operational performance, implementation processes, strategic outcomes, and socio-behavioral factors in shaping public acceptance in emerging markets. This underscores both the relevance and originality of the present study. To address this gap, this research investigates the determinants of willingness to accept (WTA) WtE policies by examining three primary factors: Factor 1: WtE Operational Effectiveness, Factor 2: WtE Implementation Support, and Factor 3: WtE Strategic Impact. These factors are analyzed in conjunction with demographic variables (age and educational attainment) and attitudinal cluster segmentation derived from K-means clustering, which categorizes respondents into all-encompassing supporters, skeptical opponents, and practical implementers. Utilizing 400 household survey responses from Batam City, Indonesia, the data were analyzed through exploratory factor analysis, cluster analysis, and binomial logistic regression. The findings indicate that implementation support is the strongest predictor of acceptance, followed by strategic impact and operational effectiveness. Additionally, older and more educated respondents exhibit higher levels of acceptance, while cluster membership reveals significant heterogeneity in community attitudes. By integrating behavioral segmentation with empirical modeling, this study contributes novel evidence regarding the social and governance determinants of WtE acceptance within a developing-country context. It addresses a critical gap in the global WtE acceptance literature and offers actionable guidance for the formulation of socially inclusive policies that promote renewable energy transition, green innovation, and sustainable development.</div></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"10 ","pages":"Article 100128"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146090161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes practices like urban mining essential to prevent countries from incurring economic loss due to unrecovered materials from E-waste. While most developed countries are adopting numerous policies in this regard, developing countries like India still face challenges in fully operationalizing such practices. Thus, it is crucial to understand the underlying issues from the perspectives of various stakeholders involved in it. This study is one such attempt, which focuses on the Information Technology companies and recyclers based in Hyderabad, India, to understand their E-waste management. By engaging with the concerned stakeholders through a primary survey, the study finds that both companies and recyclers are progressing towards the adoption of circular E-waste management practices. In most cases, the companies, dispose of their E-waste by selling it to dismantlers or sending it for refurbishment. The authorised recyclers, on the other hand, are employing urban mining procedures to extract metals and materials from E-waste for further use. However, both stakeholders opine that the prevalence of the informal sector and lack of awareness are barriers to E-waste urban mining. Thus, the study elucidates the need for innovative policies in this regard and subsidizing formal recycling, while also increasing consumer awareness to promote circular E-waste management. The research expands the discussion in this field by incorporating the perspectives of one of the bulk consumers of E-waste, i.e., Information Technology companies, and highlights the practices adopted, barriers, and drivers to safe E-waste management.</div></div>","PeriodicalId":100255,"journal":{"name":"Cleaner Production Letters","volume":"10 ","pages":"Article 100127"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145798581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the output of LCA could still be valuable for residents, especially in terms of communicating their alternative way of life. It is also worth noting that the barriers to LCA adoption are similar in both industrial contexts and sustainable communities.
