Directive (EU) 2023/2413 requires Member States to designate “renewable acceleration areas” where renewable projects can be rapidly implemented with minimal environmental impact. However, the methodological basis for identifying such areas remains underdeveloped and uneven across countries. This paper proposes a methodological framework for identing these areas using the case of wind energy implementation in mainland Portugal, with implications for other EU countries. Results show that, under the most restrictive scenario, wind energy development is incompatible or highly inadvisable in 95% of the territory. Still, land remains available for installing 11,513 turbines, equating to 23,026 MW (assuming 2 MW per turbine). A less conservative interpretation of slope restrictions would allow for the installation of 616 additional turbines. These findings highlight that particular attention should be paid to technical criteria, such as slope, in the same way that environmental protection and population-related factors are critically reviewed. It also emphasizes the need to assess “incompatible” areas more critically, categorizing them by the type and number of constraints. Proximity to energy demand is highlighted as a key factor for enhancing self-sufficiency and reducing externalities. Finally, it is recommended that suitability weightings be delegated to local planners, fostering flexibility and local empowerment with the involvement of experts familiar with the territory to be planned. This approach promotes balanced and flexible renewable energy zoning to the implementation of EU renewable energy targets and planning mandates.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"18 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122623","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}

To address these issues, this study aims to design and evaluate the performance of low-carbon concrete mixes prepared through a collaborative effect of pozzolans (such as volcanic ash (VA), pulverized fuel ash (PFA), glass powder (GP), and ground granulated blast furnace slag (GGBS)) and recycled concrete aggregate (RCA). For this motive, various tests were performed to assess the mechanical properties, microstructural characteristics, environmental impact, and production cost of low-carbon concrete mixes with respect to OPC-based concrete. Test results revealed that the inclusion of 20% RCA reduced the compressive, splitting tensile, and flexural strengths by 12%, 9%, and 16%, respectively. However, the inclusion of 30–45% pozzolanic materials significantly enhanced the mechanical properties of recycled concrete, with the 10GP-30GGBS combination demonstrating the highest enhancements. Ultrasonic pulse velocity (UPV) tests revealed about 5–11%, 9–11%, and 11–14% improvements for the samples comprising GP-VA, GP-PFA, and GP-GGBS, respectively. The water absorption progressively reduced from 4.9% to 3.6% for GP-VA combinations, from 4.6% to 3.3% for GP-PFA combinations, and from 4.0% to 2.9% for GP-GGBS combinations. From the microstructure observation and EDX analysis, notable improvements were found at the micro level together with the presence of higher silica content in pozzolan-based mixes, which contributed to the additional formation of CSH and CASH gels. Furthermore, environmental impact and cost analysis of modified mixes revealed significant reductions in carbon emissions (up to 39%) and overall cost (up to 16%) in comparison to the reference sample. Overall, it can be inferred that the combined use of GP-VA, GP-PFA, and GP-GGBS as replacements for OPC in low-carbon concrete mixes effectively enhances mechanical properties, reduces environmental impact, and lowers production costs, making it a viable approach for sustainable concrete production.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"46 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130546","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}

Different from existing research that focus on urban internal factors, this study aims to explore the urban carbon reduction from the perspective of urban network. Drawing on urban network theory, Neo-institutional theory, and the carbon curse theory, this study uses fixed effect model, Spatial Durbin model and data from 276 Chinese cities from 2010 to 2019 to reveal the impact of urban network position on carbon emissions. It can be found that the urban carbon emission increased by 1.19 times during the research time span. The strength of network connections among cities in 2019 was 2.38 times that in 2010. A higher position within the urban network correlates with lower urban carbon emissions. The urban network position could reduce carbon emissions by the mediating path of industrial structure upgrading, which is effective in both resource-based cities and non-resource-based cities. But natural resource dependence plays a moderating role in the carbon reduction effect of network position, with different effects at vary stages of resource-based cities. Additionally, the spillover effect of higher urban position increases the carbon emission of neighboring cities from the perspective of geographical proximity, and decreases the carbon emission of economic neighboring cities and administrative neighboring cities. This study provides policy recommendations for integrating urban carbon reduction with network development, considering heterogeneous impacts, and addressing the carbon curse.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"44 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122628","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 proposed a multi-scale analytical framework that identified spatial scale characteristics, summarized patterns, analyzed causes, and provided management suggestions. Focusing on the Yangtze River Delta, the study quantified five typical ESs at grid, county, and city scales, identifying their characteristics through spatial autocorrelation, trade-offs, synergies, and ES bundles. XGBoost and random forest models were used to identify dominant socio-ecological factors at different scales, while the partial least squares-structural equation modeling (PLS-SEM) revealed the impact pathways of these drivers and their direct and indirect effects on ESs. Key findings included: (1) Strong spatial autocorrelation was observed across all ESs, with carbon sequestration (CS) demonstrating the greatest scale stability and food supply (FS) exhibiting the highest variability; (2) Trade-offs were concentrated in northern cultivated areas, while synergies thrived in southwestern mountains, with synergies increasing and trade-offs decreasing as spatial scale expands; (3) Natural factors (e.g., climate, geography, vegetation) primarily influenced ESs, but socio-economic and landscape factors increasingly shaped FS and CS at larger scales; (4) Geographic conditions had the strongest positive impact, climate effects diminished with increasing scale, and urbanization, particularly the proportion of built-up land, negatively influenced ESs through its impact on vegetation cover. These insights underscore the need for tailored, scale-specific strategies to support sustainable ecosystem management and urban development.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"140 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122877","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}

To address the existing gaps in spatial data regarding mangroves and their capacity for disaster risk reduction. In this study, multiple scenarios were set up to predict future spatial changes in mangroves. A spatial optimization simulation and prediction method for mangrove restoration and conservation has been established, integrating Coupled Artificial Neural Networks (ANN), Multi-Objective Planning (MOP), and Cellular Automata (CA) models. Future spatial simulations of mangroves from 2025 to 2035 were conducted under three scenarios: Trend Continuation Scenario (TCS), Policy Planning Scenario (PPS), and Human-Nature Harmonious Coexistence Scenario (H-NHCS). Based on this, an analysis of future changes under the three scenarios was carried out. Mangrove disaster prevention and mitigation functions were ultimately predicted for SDG13.1. The resulting dataset has a multi-year OA of more than 0.89, a kappa index of more than 0.86, and good integration with the ANN-MOP-CA model. Based on the analysis of mangrove remote sensing data set extracted by Sentinel from 2016 to 2024, the mangrove area increased by 34 %. From 2024 to 2035, most of the TCS area showed a seaward expansion trend. The stability of mangrove changes over the years was greater than 50 %, and the degradation rate of H-NHCS mangroves was less than 5 %. The future wave dissipation capacity and ability of mangroves to withstand storm surges have improved annually, and areas with a relatively weak ability to cope with disasters are dominated by open bays and built-up areas.

It does so by estimating costs and optimizing CCUS value chains that encompass emitters from the fertilizer, oil refining, iron and steel, and cement industries. Our analysis, coupled with consultations with industry experts, reveals that the implementation of CCUS has the potential to reduce overall industrial CO2 emissions in the region by up to 25%. In some countries, the formation of CCUS clusters emerges as a straightforward decarbonization strategy, whereas in others, the presence of widely spaced emission sources and sinks necessitates coordinated development of pipeline infrastructure and crosscountry collaboration. This potential is further bolstered by supranational programs. However, it is worth noting that the current EU Emission Trading System (ETS) scheme does not seem to sufficiently incentivize investments in carbon capture. The availability of free ETS allowances still covers a significant portion of capturable CO2 emissions, potentially discouraging individual plants from pursuing expensive carbon capture initiatives.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"20 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122890","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}

Organic amendments and enhanced efficiency fertilizers (EEFs) can improve soil organic matter (SOM) and nutrient use efficiency, but their optimal combination for rice production is unclear. Through three seasons field experiments, this study explores the effects of integrating organic amendments, EEFs, and 4R nitrogen (N) management stewardship (Right rate, time, source, and place) on enhancing rice grain attributes, N use efficiency (NUE) and soil quality in tropical paddy system. It compared one conventional practice with seven ‘4Rplus’ treatments (4R concept combined with EEFs and organic amendments), reducing N application from 180 kg N ha^-1 (conventional) to 140 kg N ha^-1. Results showed that 20% and 40% organic N substitution increased rice yield by 4% and 5%, respectively, under reduced N application, while a 60% substitution decreased yield by 3%. As the proportion of organic substitutes increased, the content of mineral nutrients such as magnesium, zinc, and iron increased, and the amino acid structure is improved. The 40% organic substitution combined with controlled release fertilizer (40MC) treatment achieved the best performance on improving grain quality, with lower amylose content (16.3%) and crude protein content (65.2 mg g^-1), higher head rice rate (64.2%), and lower chalkiness (1.4%). Controlled release fertilizer (CRF) was more effective than inhibitor-based EEFs in improving rice yields, quality and NUE. The 40MC treatment reduced N surplus to 60 kg N ha^-1 and achieved a NUE of 57%. Inhibitor-based treatments (urease inhibitor and nitrification inhibitor) averaged an N surplus of 75 kg N ha^-1 with NUE of 46%, with no significant differences in grain quality between inhibitors. Supplementing 40MC with amino acid powder further increased yield by 10% and NUE to 60%, while biochar application did not improve rice quality or yield but significantly enhanced soil fertility. These findings highlight that integrating organic amendments with EEFs is a promising strategy for achieving sustainable production in tropical paddy systems, synergistically enhancing rice yield, quality, and soil fertility while improving NUE and minimizing N losses.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"24 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122631","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}

To address these challenges, this paper aims to optimise both shredding performance and environmental impact by using Finite Element Methods (FEM) and Life Cycle Assessment (LCA). A FEM simulation model is developed and thoroughly validated against performance criteria, including particle size &amp; distribution and energy consumption.

The FEM model aligns the significant inputs and the outcomes of the shredding simulation with the scope and inventory of LCA. The FEM-LCA model is employed to investigate the effects of key design and operational variables on shredding performance and environmental indicators, including particle characteristics, throughput, energy consumption, and CO₂ emissions. By constructing an input-output correlation coefficient matrix, we identify parameters that have strong correlations with both shredding performance and environmental outcomes.
