The fundamental criticism put forth by degrowth is that unlimited growth cannot be sustained within the planetary boundaries.Citizen-owned and democratically controlled Community Energy Initiatives (CEI) engage since many years in the sustainable energy transition. This paper investigates to what extent they align with the degrowth movement. Drawing from an inventory of over 10000 European Community Energy Initiatives, we go beyond the few case studies and theoretical think-pieces. We test potential alignment by empirically investigating indicators for the following degrowth imperatives: (1) Reduce environmental impact, (2) Re-orient economic priorities, (3) Reduce inequality (4) Foster democratic decision making, and (5) Re-localize production and consumption. The results suggest a strong alignment with the environmental impact reduction, democratic decision making, and re-localized production and consumption imperatives, while the alignment with the economic re-orientation and inequality reduction imperatives varies considerably across countries and types of initiatives.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"18 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910001","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 utilizes panel data from 243 Chinese cities (2011–2020) to examine the impact of digital industry agglomeration (DIA) on urban carbon peaking and carbon neutrality (CPCN) and explores the nonlinear moderating role of digital technology innovation (DTI). The results indicate that (1) DIA positively contributes to CPCN, a finding that remains robust across multiple empirical tests; (2) DTI exhibits a nonlinear moderating effect, with a significant threshold at 469.949, beyond which the marginal impact of DIA on CPCN becomes more pronounced; and (3) this moderating effect is primarily driven by disruptive rather than progressive DTI and is more evident in economically developed cities and those with stronger low-carbon development endowments. These findings provide valuable policy insights into integrating DIA and DTI to accelerate CPCN efforts in China and serve as a reference for other high-emission emerging economies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"23 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905507","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}

The model simulates the macroeconomic and environmental effects of unexpected shocks emanating from green technology adoption, renewable energy output, green consumption, fossil fuel taxation, and green subsidies. The findings from the study show that green industrialization stimulates economic output while reducing carbon emissions. These results imply that <em>greening existing production processes and creating new green industries guarantee the dual benefits of green industrialization, ensuring economic prosperity and environmental sustainability in Africa.</em> However, the effectiveness of green industrial development is conditional on targeted government interventions, including strengthening state institutions, ensuring the cost-effectiveness of green technologies, and enhancing the affordability of green goods<strong>.</strong> By implementing these measures, Africa can maximize economic sustainability arising from green industrialization.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"58 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909840","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}

Minimizing freshwater consumption is essential for adopting sustainable practices. A limited number of studies are available in the literature exploring the possibility of recycling dyeing effluent through ozonation as an eco-friendly approach. Therefore, in the present work, the recycling of effluents obtained after dyeing with Reactive Red 198 (RR198) and Reactive Blue 21 (RB21) dyes through ozonation treatment has been studied. Nearly complete decolourization with COD removal efficiency of 32 % was obtained for both dye effluents after 15 min of ozonation. The qualities of recycled dyed fabrics were compared to fresh water-dyed fabrics through spectrophotometric analysis and colour fastness tests. These qualities for both dyed fabrics with recycled effluent were found to be either in excellent or good category after each recycle. Comparative analysis of freshwater and chemical requirements, along with cost savings, was conducted over four dyeing attempts. The study revealed significant savings with recycled effluent dyeing including 60 % reduction in fresh water usage and 75 % in salt consumption compared to conventional freshwater dyeing. Thus, recycling textile dyeing effluent through ozonation treatment was found to be a resource efficient approach. This approach not only significantly reduces wastewater volumes but also freshwater demand without compromising the colour-related qualities of dyed fabrics. Additionally, it minimizes operational expenses, thereby, supporting textile industry's shift toward sustainable practices.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"26 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910007","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}

Hickenbottom","doi":"10.1016/j.jclepro.2025.145646","DOIUrl":"https://doi.org/10.1016/j.jclepro.2025.145646","url":null,"abstract":"Membrane Distillation (MD) is an emerging thermally assisted desalination process that can produce high-quality water from high-salinity streams using low-grade heat, thus supporting near-zero liquid discharge. To adopt MD as a concentrate management technology, it is essential to compare environmental and economic implications of MD to conventional management alternatives. This work presents a comparative environmental life cycle and cost assessment of MD and conventional concentrate management technologies (i.e., evaporation ponds, deep well injection (DWI), mechanical concentrators) for the treatment of saline streams. Environmental impacts are quantified as a single score in pts/m³. Results indicate that MD has the second lowest environmental impact scores, with a range between 0.02 -0.04 pts/m³ and cost from 0.81-1.52 USD/m³. Although evaporation ponds and DWI have some of the lowest environmental impacts (0.01-0.13 pt/m³) and disposal costs (1.05-6.77 USD/m³), the application of these technologies are limited to geographical constrains (e.g., climate and geology). Additionally, despite the low environmental impact of evaporation ponds and DWI, they do not place value on resource recovery. Finally, although brine concentrators offer a modular and scalable approach to concentrate management, they have the highest impacts and costs ranging from 1.04-1.18 pts/m³ and 7.47-7.94 USD/m³, respectively. In each system, the main environmental and cost stressors can differ, signifying the lowest cost does not always align with the lowest impact – underscoring the need for tailored treatment solutions. Overall, results support MD as a cost-competitive concentrate management technology with low environmental impacts and the added benefit of producing high-quality water.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"19 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905509","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}

Such studies typically conceptualize GDCs as a single construct and, in rarer cases, as a group of noninteracting constructs. This study takes a different approach by conceptualizing GDCs as a set of constructs organized under three stages during which dynamic capabilities are applied (i.e., “sensing”, “seizing”, and “transforming”). The constructs “market orientation” (MO), “sustainability orientation” (SO), “technological orientation” (TO), and “green process innovation” (GPI) are used as proxies for GDCs to develop a model describing two distinct paths from MO to GPI. The model is investigated through a survey of Danish manufacturing firms (n=337). The results confirm the hypotheses that SO and TO mediate the relationship between MO and GPI. Interestingly, there is no support for a direct relationship between MO and GPI, which implies that SO and TO fully mediate this relationship. Second, the results show that both mediation relationships are associated with competitive advantages in the form of increased product quality, whereas no support is found for effects on lead times and costs. Overall, the study adds to the understanding of GDCs by conceptualizing them as a set of constructs organized under three stages during which different GDCs are applied. This conceptualization offers future research a more nuanced operationalization of GDCs, which may lead to additional insights into their conditions and effects.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"13 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910002","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 used satellite remote sensing data to obtain the spatial and temporal distribution pattern of the Ningdong Coal Base PV power plant. The surface energy balance characteristics of MPVs were analysed using the Surface Energy Balance Algorithm for Land (SEBAL) time series, and the carbon emission reduction benefits were estimated using a life cycle assessment (LCA). The results show that the Ningdong Coal-based PV power plant covers an area of 95.34 km² and is mainly located in the coal mining subsidence area. The construction of the PV power plant significantly impacted the characteristics of surface energy balance. 1-2 years after construction, vegetation growth in the PV area is better than in the Control area, evaporation has increased, and surface temperature and albedo have decreased. The Ningdong Coal Base MPVs have huge benefits in terms of carbon emission reduction. With an average annual electricity generation of 7.37×109 kWh, they can offset the cumulative electricity consumption after 2-3 years of operation. This study helps to understand the dynamic changes in the surface energy balance characteristics of the construction of PV systems in mining areas and provides valuable methodological guidance and data references for those involved in the technical research and decision-making of MPVs.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"31 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910005","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}

Cabrera","doi":"10.1016/j.jclepro.2025.145636","DOIUrl":"https://doi.org/10.1016/j.jclepro.2025.145636","url":null,"abstract":"In pursuit of agricultural resilience and sustainability, the European Union (EU) Common Agricultural Policy (CAP) advocates for effective and diverse crop rotations. Yet, dairy farmers face intricate planning challenges due to diet and market complexities. This study introduces a novel mixed integer linear programming (MILP) model that optimizes both crop planning and dairy cow diet formulation within mixed crop-livestock farming systems, considering CAP crop rotation regulations and Greenhouse Gas (GHG) environmental policies. Our approach employs a two-step framework to address enteric methane emissions. First, a multi-objective optimization generates a set of Pareto-efficient solutions, offering policymakers insights into trade-offs between economic returns and methane emissions. Second, the TAX policy (introducing a methane emissions tax) and RED policy (imposing explicit methane reduction targets) can be used to determine the required tax rates or reduction levels to achieve the selected policy goals. These policies also reveal the effects of varying tax rates and reduction levels on crop planning and diet formulation. The proposed approach is illustrated, without loss of generality, on three representative Italian dairy farms – producing milk without Protected Designation of Origin (PDO) rules (STD), or following Grana Padano (GP), or Parmigiano Reggiano (PR) PDO rules. We consider 33 types of crops, allowing double cropping, and 11 animal groups that have distinct nutritional requirements. The multi-objective optimization highlights non-linear trade-offs between economic returns and methane emissions, underscoring the critical role of policymakers in balancing these objectives. RED policy scenarios prove more effective at GHG mitigation than TAX policies. Methane mitigation initiatives prompt dietary adjustments, resulting in higher crude protein percentages and reduced neutral detergent fiber content in cow diets, consequently influencing crop plans. Moreover, under stringent GHG mitigation requirements, dairy farmers lean towards purchasing feed from the market rather than cultivating it on-farm.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"18 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905765","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}
