Planning is often hindered by the complex interplay of multiple ecosystem services (ESs), their trade-offs, and environmental constraints, leading to potentially inefficient or maladaptive interventions. This study develops a multi-level spatial decision framework to guide cleaner and more effective ecological management in the Gansu section of the NFPP (GS-NFPPA). We quantified four key ESs (Net Primary Productivity, Water Yield, Sand Fixation, and Soil Conservation) from 2000 to 2020 and used Ordered Weighted Averaging (OWA) to identify priority Ecological Conservation Areas (ECAs), trade-off analysis for Ecological Trade-off Areas (ETAs), and constraint line analysis for vegetation (NDVI) driven Ecological Sensitive Areas (ESAs). Unlike single-objective approaches, this framework innovatively integrates conservation priorities, ES trade-offs, and nonlinear vegetation sensitivity, enabling a shift from broad-stroke conservation to targeted, resource-efficient interventions. Our results show significant overall ES improvement across the GS-NFPPA. The framework identified optimal ECAs covering approximately 10.92 % of the region, critical ETAs with intense ES competition covering 9.23 %, and land-use-specific NDVI thresholds that define ESAs where ES provision can decline. The spatial overlay of these zones pinpointed \"Comprehensive Key Areas\" where high conservation value, trade-offs, and sensitivity converge, demanding the most sophisticated management. This integrated multi-level framework provides a robust scientific basis for targeted, differentiated ecological management strategies. This preventative and evidence-based approach offers a transferable model for enhancing the sustainability of large-scale environmental programs globally.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"122 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255537","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}

Using annual data from 1990 to 2022 from the Federal Statistical Office, Sharp and Fuzzy Regression Discontinuity Designs (RDDs) were applied to estimate causal effects. The Sharp RDD assumes precise policy implementation by the 2012 cutoff date, while the Fuzzy RDD accounts for delays or incomplete adoption in the real-world implementation by municipalities and the waste sector. These quasi-experimental methods leverage the exogenous timing of the legal reform to assess its impact on waste volumes. The findings suggest a statistically significant short-term increase of 8.44% (Sharp RDD) to 12.07% (Fuzzy RDD). This increase is likely attributable to enhanced enforcement, expansion of separate collection, improved reporting, and citizen compliance. The RDD method confirmed the nationwide effect by isolating the law’s impact via its fixed implementation date. In subsequent years, this positive trend weakened, with annual growth decreasing by about 0.86% compared to pre-legislation, suggesting an initial adjustment followed by long-term dampening. This study contributes to evaluating environmental legislation by showing that legal instruments can have measurable, though time-limited, effects on material flows. Although it lacks direct analysis of complementary measures (e.g., incentives, infrastructure), it underscores their importance for sustained long-term impact. To the best of our knowledge, this is the first causal RDD-based evaluation of the KrWG, providing rare quantitative evidence of the impact of circular economy policy.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"28 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255221","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}

In this study, a cultivated land health evaluation system was developed based on the vitality–organization–resilience framework from the perspective of productivity and sustainability. The health gain–loss (HGL) of cultivated land requisition and compensation in the Pearl River Delta (PRD) region from 2000 to 2020 was quantitatively assessed. The ecological vulnerability of the region was assessed using the sensitivity–recovery–pressure model and spatial principal component analysis. Results revealed systematic implementation biases in the land requisition and compensation practices in the PRD region such as more requisition, less compensation; near requisition, distant compensation; prime requisition, inferior compensation; sustainable requisition; and unsustainable compensation. From 2000 to 2020, the average cultivated land health level fluctuated but marginally increased, whereas the health balance between requisitioned and compensated lands transitioned from deterioration to gradual improvement. The spatial heterogeneity in ecological vulnerability increased and 28.80 % of cultivated lands were located in high or relatively high vulnerability zones in 2020, indicating that a portion of cultivated land remained at high health risk. By integrating spatial ecological vulnerability assessments with HGL patterns, cultivated lands were classified into four distinct health risk categories to devise informed targeted management strategies. An adaptive governance framework was proposed for the CLRCBP that aligns with rapid urbanization dynamics and the functional transition requirements of contemporary cultivated land systems.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"66 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255297","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 analysis identifies environmental hotspots, evaluates sensitivity to production variables and compares PDCs with conventional wood/superabsorbent polymer (SAP) alternatives, adhering to ISO 14040/14,044 standards. The assessment reveals that, the material preparation stage is the primary environmental hotspot contributing 63.4 % to abiotic resource depletion, 75.1 % to cumulative energy demand, and 71.3 % to global warming due to high electricity consumption. The LCA indicates that the current PDC production process has a higher environmental impact than conventional wood/SAP cores, with 1.5 times higher global warming emissions and consuming 3.2 times greater energy consumption per functional unit. However, sensitivity analysis suggests that PDCs have significant potential for environmental improvement through process optimization. This optimization, involving pre-drying the biomass ahead of manufacturing and avoiding the use of bleaching chemicals, could, for instance, reduce global warming potential by ∼30 %.

Social innovation (SI), particularly in the field of participatory financing, can create innovative, community-based models to mobilize the financial resources needed for renewable energy (RE) projects and reduce investment barriers. Therefore, accurately identifying the factors influencing citizens’ investment in this sector is essential for designing effective policies, financial instruments, and implementation models. We examined a national-scale SI program in Iran and analyzed data from 2077 participants in the installation of residential rooftop solar systems. We applied four machine learning algorithms—Logistic Regression (LR), Random Forest (RF), Support Vector Machine (SVM), and K-Nearest Neighbors (KNN)—to predict investment behavior. The RF model achieved the highest test accuracy (77 %) and revealed that connection to the national electricity grid, access to loans, government incentives, and understanding of benefits were the most important predictors. Public attitude towards solar energy, peer pressure, gender, type of residence, and homeownership status were also significant, whereas household income, education, and high solar potential had comparatively lower impact. The findings suggest that in oil-rich economies, removing financial barriers should be complemented by social interventions. From a policy perspective, these results underscore the need to design segmented programs based on demographic and locational characteristics, utilizing tools such as PAYG financing, crowdfunding models, demonstration projects in rural and underserved areas, and leveraging the influence of social networks to enhance participation. By linking data-driven analysis with SI, this study provides a practical framework for policymakers and RE stakeholders to accelerate and broaden the transition to clean energy.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"122 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255163","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}

Thus, researchers often simplify the UBEM models and improve the accuracy through calibration. Result-based bias prediction (BP) and parameter-based estimation (PE) are the two of the most-commonly-used calibration frameworks, but the data requirements, capability boundaries, and applicable scenarios are still unclear in previous studies due to the insufficient sample space. Therefore, the study carried out a systematic comparison between the two calibration frameworks through a case study on 3442 public buildings with 256,968 monthly electricity consumption records. Nine types of buildings' energy consumption were modelled and simulated, in which the PE provided calibrated archetype models, and the BP provided the prediction on primary simulation bias. As a conclusion, the BP showed better accuracy, generalization, and robustness crossing different tasks than the PE did, and so would be more feasible for most of the analytical simulations focusing on an accurate energy assessment, especially those in building maintenance or Urban Sustainability Assessment scenarios. The PE was suggested if the persistence on model interpretability to explain the composition or sensitivity of energy consumption overperform the accuracy, which is widely required in design stage. In addition, the implementation of Transfer Learning could improve BP targeting at mix-use building simulations. This study contributes to the selection of calibration methods cross the main UBEM applications.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"23 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255531","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 explores the use of cathodic auxiliary agents to enhance the EK remediation of PFOA-contaminated soil. Among the desorption tests, SDS (50.93 %) and NaC (43.62 %) were most effective in desorbing PFOA through electrostatic, hydrophobic interactions, and micelle formation, outperforming DTAB (15.29 %) and CA (37.76 %). Continuous desorption tests validated the effectiveness of employing auxiliary agents as electrolytes. EK remediation experiments revealed that these agents facilitated PFOA desorption and migration, achieving higher removal efficiencies. After 7 d, NaC achieved a greater enhancement effect than SDS, with PFOA removal rates of 58.04 % (2 V/cm) and 63.70 % (2 V/cm), respectively. PFOA accumulation in the middle soil area was observed, due to opposing electroosmotic and electrokinetic forces, with electromigration being the dominant factor. Extending remediation time alleviated this accumulation. Kinetic analysis revealed that PFOA migration in most areas followed pseudo-second-order kinetics, while the middle area exhibited first-order kinetics due to PFOA accumulation. The auxiliary agents primarily enhanced PFOA removal efficiency indirectly by influencing electromigration, electroosmosis, and desorption processes, while changes in soil physicochemical properties served as limiting factors. This study provides valuable insights into the combined effects of cathodic-enhanced EK and auxiliary agents on PFOA remediation, offering theoretical and practical guidance for the development of efficient and sustainable remediation technologies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"50 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145235231","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}

Among emerging solutions, e-methanol, synthesized from captured CO2 and green hydrogen, has been recognized as a scalable liquid energy carrier compatible with existing infrastructure. However, current system designs often evaluate carbon capture, hydrogen production, and methanol (MeOH) synthesis in isolation, with limited emphasis on integration or region-specific deployment. In this study, a novel process design, simulation model, and life cycle CO2 performance analysis have been developed for two integrated e-MeOH production pathways based on Direct Air Capture (DAC): one using direct CO2 hydrogenation (DS) and the other relying on hydrothermal co-electrolysis synthesis (HS). In both configurations, internal integrations are leveraged, such as the use of raw MeOH as an internal fuel, electrolytic oxygen reuse, and thermal integration between subsystems. The hydrothermal co-electrolysis pathway was found to outperform the direct synthesis route in both environmental and energy metrics. For a conceptual 0.3 Mt/y MeOH plant located in Japan, cradle-to-gate emissions were reduced to −0.367 kg-CO2eq/kg-MeOH for HS, compared to 0.519 for DS and 1.370 for the conventional route. Greater heat recovery further lowered energy demand. A regional sensitivity analysis indicated that in regions with low-carbon electricity (for example, in Canada), DAC-based e-methanol could achieve near-zero emissions. These findings underscore the importance of process integration and geographic energy context in determining e-methanol viability. A quantitative basis is provided to inform the scalable and regionally adaptive implementation of synthetic fuel technologies.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"32 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145229381","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}

These behaviors fall into two categories: mitigation behaviors (reducing emissions), and adaptation behaviors (minimizing health risks), with the latter subdivided into in-situ adaptations (e.g., mask-wearing) and mobility adaptations (e.g., modifying traffic modes). Mitigation and adaptation behaviors are shaped by distinct mechanisms. However, existing research has primarily focused on adaptation behaviors without systematically comparing across different behavior types. Applying adaptation-based insights to other types may undermine policy effectiveness. Moreover, most studies rely on data from limited cities, hindering understanding of national landscape and spatial variability. To address these gaps, we conducted a nationwide survey of 7457 participants across 28 Chinese provinces. Structural equation modeling was used to compare determinants of mitigation and adaptation intentions. Multilevel regression and poststratification (MRP) generated the first city-level estimates in China. Our results revealed three common drivers that consistently enhance public engagement across behaviors: perceived risk severity, perceived benefits of clean air, and socioeconomic status. However, mitigation and adaptation intentions followed distinct cognitive pathways-adaptation was shaped by dread and risk controllability, while mitigation was driven by knowledge and trust. Within adaptation, in-situ and mobility behaviors showed divergent determinants. Objective pollution indirectly shaped in-situ adaptations via perceived risk, and exerted both direct negative and indirect positive effects on other intentions. Furthermore, MRP analysis revealed three city-level patterns: economic development-driven, pollution-driven, and jointly-driven behaviors. These findings provide practical guidance for designing targeted interventions to enhance public engagement in future clean air initiatives.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"28 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145229372","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 resulting porous Gel–Chi–MNP (PS) and Gel–Chi–MNC (CS) sponges exhibited hierarchical porosity, tunable surface charge, and robust mechanical stability. Adsorption studies using methylene blue (MB, cationic) and methyl orange (MO, anionic) revealed maximum adsorption capacities of 312.4 mg g−1 for MB and 276.8 mg g−1 for MO under optimized conditions. Adsorption isotherms followed both Langmuir and Freundlich models, confirming the coexistence of monolayer and heterogeneous multilayer adsorption, while kinetic analysis indicated a hybrid mechanism involving physisorption and chemisorption. Notably, CS sponges displayed superior swelling capacity, higher reusability, and improved structural integrity compared with PS sponges, owing to the pectin coating that enhanced hydrophilicity and electrostatic interactions. The sponges retained >85 % of their dye removal efficiency after five successive adsorption–desorption cycles, demonstrating excellent regeneration potential. Furthermore, cost analysis and preliminary tests with metal ions validated their economic viability and versatility for practical wastewater treatment.
