We also examine the moderating role of pre-crisis corporate reputation in shaping these responses. An experimental full factorial design is employed based on a representative sample of U.S. adults (N = 680). Situational Crisis Communication Theory (SCCT) posits that stakeholders' attributions of responsibility are influenced by an organization's crisis history, stakeholder relationships, and reputation. Extending SCCT, the findings indicate that when a firm's pre-crisis reputation is low, consumers' behavioral responses are not significantly influenced by the crisis's potential for harm, CSR relevance, or attribution of blame. In contrast, when pre-crisis reputation is high, both potential harm and attribution of blame exert a significant effect on consumer behavior, whereas CSR relevance does not. This study makes a novel contribution by examining a comprehensive set of sustainability-related crisis types, including industry-wide collective crises, product-harm crises, and CSR-related tensions. Theoretical and managerial implications are discussed.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"1 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a Life Cycle Assessment of twelve constituents and thirty mixes (covering seven applications) representative of European horticulture.

Herein, a BiOCl/COF (BOC/COF) S-scheme heterojunction was successfully constructed via ultrasonic assistance.

The research has found that non-radical pathways collectively accounted for 89.11% of the degradation activity, endowing the system with high selectivity. It is worth noting that the BC-20 membrane can efficiently eliminate TC in a continuous-flow wastewater treatment system. Furthermore, BC-20 can degrade TC in an enlarged reactor under natural sunlight irradiation. The three possible degradation pathways were analyzed through Fukui function and LC-MS.

The framework integrates phased deployment across three time horizons (2030, 2040, 2050) under three decarbonization pathways, carbon pricing for uncaptured emissions, and selective reuse of existing pipelines within a single optimization. Seven mode-pressure variants are considered, with mode-transition costs derived from a 49-transition simulation matrix. The framework is applied to twelve major German steel emitters connected to the Northern Lights offshore storage site via three candidate ports. The cost-optimal network shifts from truck-and-rail logistics in the early, low-volume stage to a dense-phase pipeline backbone as captured volumes grow. Unit transport costs remain within 15–18 €/tCO<ce:inf loc=\"post\">2</ce:inf> across the scenarios. The marginal cost of expanding transport and conditioning capacity stabilizes at 13–14 €/tCO<ce:inf loc=\"post\">2</ce:inf> from 2040 onward. These figures indicate that transport is not the binding economic constraint on scaling up capture ambition, rather than that CCUS as a whole is inexpensive. Existing pipeline reuse is found to be capacity- and stage-dependent: sufficiently large reused assets can reduce new-build requirements. The framework offers a transferable approach for cleaner industrial logistics design, supporting the transition to low-carbon hard-to-abate sectors in Europe and beyond.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"70 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148852406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the growing volume of end-of-life solar equipment, significant uncertainties persist regarding recycling costs, especially in emerging economies, where structured economic assessment approaches remain limited. This study proposes a structured decision-support framework to support the assessment and management of recycling costs associated with end-of-life photovoltaic panels. A Systematic Literature Review was conducted to identify cost components related to photovoltaic recycling, which were then structured using the Function Analysis System Technique. Expert evaluation was used to validate cost relevance and structure. The Fuzzy Delphi method and Mean Rank Position were applied to reach consensus on cost relevance, while the Stepwise Weight Assessment Ratio Analysis method was used to assign weights to cost categories. The resulting framework consolidates consensual cost components into weighted functional clusters, providing a structured basis for economic assessment and supporting decision-making in photovoltaic panel recycling initiatives. The proposed framework contributes to resource conservation and circular economy strategies by supporting managers, investors, and policymakers in structuring and comparing the cost dimensions associated with photovoltaic panel recycling in emerging economies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"48 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148852376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhancing thermal resilience requires coordinated interventions across social, economic, ecological, and technological systems. However, existing studies remain limited in clearly identifying key intervention domains and in understanding how these domains interact within an integrated systems perspective. Therefore, the overarching aim of this research is to identify key thermal resilience interventions, examine expert-perceived interrelationships among them, and develop an expert-informed decision-support analytical framework for interpreting and prioritising interventions. Focus groups with experts from China and the UK were conducted using a modified Problem Tree Analysis approach to elicit intervention-related problems, perceived causes and effects. A subsequent web-based survey was used to assess the perceived influence relationships among the identified intervention domains. These relationships were analysed using the Decision-Making Trial and Evaluation Laboratory-based Analytic Network Process (DANP) method. The results reveal distinct expert-perceived influence structures among intervention domains across Social-Economic-Ecological-Technological (SEET) system dimensions, while also highlighting the central role of policy development and planning and economic feasibility in shaping the implementation of intervention domains. The key contribution of this study is the development of an expert-informed decision-support analytical framework that systematically captures cross-dimensional influence relationships and supports the prioritisation of thermal resilience interventions. The findings provide an expert-informed analytical basis for supporting context-sensitive decision-making in urban heat adaptation under climate change.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"348 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148852378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study identifies the timing of these breaks in the BRI LIB trade network from 2017 to 2022 to examine how geographic, institutional, and technological factors drive trade tie dynamics across distinct evolutionary phases. Using trade data from 56 BRI countries, this study integrates Change Point Detection with the Separable Temporal Exponential Random Graph Model (CPD-STERGM) to estimate phase-specific mechanisms of tie formation and dissolution. Four breakpoints are detected at October 2017, January 2019, January 2020, and April 2022. The network evolved through five phases, exhibiting a pronounced “core-transit-periphery” stratification. Driving mechanisms shifted from “hard” factors like geographic proximity to “soft” factors including common language and bilateral investment treaties. Consequently, this study proposes a differentiated supply chain governance framework encompassing emergency response mechanisms, logistics hub upgrading, and institutional coordination via the mutual recognition of standards and investment protection. This offers actionable policy insights to enhance LIB supply chain resilience within the BRI.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"5 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a critical knowledge gap remains regarding the extent to which NbS concepts are systematically integrated into higher education curricula, despite the role of universities as institutional settings for developing and disseminating knowledge relevant to NbS. In this study, we examined the degree of curricular integration of NbS within university study programs in water resources management (WRM) and hydrology at the undergraduate, master's, and doctoral levels across 25 countries in 8 geographic regions. Data were collected through a structured survey, and curricula analysis was conducted, in which the proportion of NbS content within each course was categorized into Major (core focus), Moderate (partial coverage), Minor (peripheral inclusion), or NA (no explicit content). Our findings reveal significant regional and disciplinary contrasts. Countries with research-active disciplines, such as engineering and environmental science, and those with formal NbS policy frameworks, such as in the EU, show earlier or more extensive NbS curricular integration. Contrary to the interdisciplinary nature of NbS, we find that NbS are predominantly, yet sporadically, embedded in civil and environmental engineering and natural sciences, with minimal contributions from other disciplines, such as social sciences. Moreover, NbS concept remains insufficiently represented at the undergraduate level as 45.9% of the courses contain Minor content and 33.9% have no explicit NbS content, which represents a missed opportunity for NbS exposure during foundational professional study and training. More substantive NbS content appears in master's and doctoral programs, suggesting that NbS remains a specialized, research-oriented topic rather than foundational curriculum content. Faculty-led NbS teaching initiatives, identified through the survey, though encouraging, reveal a misalignment between high NbS research activity and their low curricular integration, where 31–41% of lecturers in courses with NA and Minor NbS integration do publish NbS-related research. Without explicit NbS framing in WRM and hydrology curricula, study programs may remain confined to specific disciplinary silos, potentially limiting students' overall engagement with NbS concepts. These findings collectively suggest that advancing comprehensive NbS integration in higher education may require deliberate and coordinated curricular reform across institutional levels, highlighting the importance of a whole-institution approach that systematically integrates NbS into curriculum, governance structures, and campus infrastructure.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"35 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148852404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
