The complex international situation threatens global trade, emphasizing the role of domestic industrial divisions. However, whether the economic linkage changes brought by thriving domestic divisions burden emission reductions hasn't received enough attention, though it's vital for carbon neutrality. To fill this gap, we developed a novel analytical framework by constructing a Global-Chinese-provincial Nested Multi-regional Input-Output (NMRIO) table, enabling comprehensive analysis across global, regional, and sub-national scales. We attempted to determine whether domestic divisions would impose a greater burden on sub-national emission reduction and how they function compared to participation in global divisions. We found that provincial participation in domestic divisions showed an upward trend during the study periods. However, compared with global divisions, domestic industrial divisions demonstrate a stronger effect increasing carbon emissions. Such emission growth is primarily driven by production scale expansion and carbonization of sub-sector structures within aggregate industries. Technology-driven reduction in carbon emission intensity is critical to mitigating the rise in emissions under domestic divisions, particularly between provinces in western and central regions and eastern regions. Global regional analysis shows that divisions with EU and North American countries will increase the carbon emissions, while those with the One Belt and One Road have no significant emission effects. Moreover, in the global divisions, a higher proportion of vertical specialization helps mitigate carbon emissions in provinces, while in the domestic divisions, a more downstream position can more significantly alleviate the carbon emissions driven by divisions.

Aluminum is a non-ferrous metal leading in consumption, energy, and carbon intensity. China's first “old-for-new” policy, initiated in 2009, accelerated the production, consumption, and obsolescence of aluminum-containing products. In 2024, the Chinese government launched a larger-scale version of the “old-for-new” program. In this new context, this study integrated material flow analysis and field survey to measure China's aluminum metabolism from 2009 to 2050. The new findings reveal that policy-driven interventions could amplify recycling potential by 83.3 % (appliances) and 50 % (vehicles) compared to the baseline, with environmental gains closely linked to the combinations of policy intensity. Consumer participation rates and recycling technology efficiency emerge as critical bottlenecks—synergistic optimization yields multiplier effects. Uncertainty analysis reveals 28 % (appliance) and 26–50 % (vehicles) variability in emission reduction and energy saving forecasts, while air conditioners and new energy vehicles drive 49 % of recycled aluminum growth in 2050. This study identified the key drivers that influence recycling potential and its environmental impacts, providing crucial support for managerial decision-making and a robust theoretical underpinning for optimizing aluminum management and advancing circular economy policies.

To cope with the surging global energy demands and escalating environmental challenges, the sustainable development of the photovoltaic (PV) industry has become a pivotal solution for balancing energy security and ecological conservation. This study fills a critical gap in assessing China's PV industry sustainability by developing a context-adaptive multi-driver model, which systematically integrates economic, environmental, and resource dimensions and optimizes for China's regional heterogeneity and industrial constraints. The model incorporates core drivers (energy transition imperatives, technological advancements, economic incentives) and limiting factors (policy uncertainties, market competition pressures, land resource constraints) in the development of the PV industry to elucidate the multi-dimensional benefits, applying it to a provincial empirical analysis of sustainable potential. Findings reveal China's PV energy exhibits significant regional disparities, with economic costs ranging from 0.56 to 1.27CNY/kWh. A 1 kW PV plant generates annual environmental benefits of 37.24 to 655.19CNY, with developed regions demonstrating distinct carbon mitigation advantages. Land use benefits generally decline from southeast to northwest China. Employing the multi-driver evaluation model, the sustainability index (SI) of China's PV industry ranges from 0.09 to 0.83, with higher values in southeastern coastal regions compared to western inland areas. Thirty provinces are classified into three zones: Advantage Spearheading Zone, Potential Unleashing Zone, and Resource Unactivated Zone. Zone-specific strategies are proposed to promote the high-quality and sustainable development of the PV industry.

A territory, which is a geographical area qualified by a legal affiliation or by a natural or cultural feature, presents an appropriate scale for establishing responsibilities and initiating sustainable development actions. At the same time, globalization implies constant interaction of territories with the rest of the world. The management of territorial projects therefore requires a revised set of environmental assessment tools that consider local and global issues with a multi-scale perspective. The environmental benefits of land use policies can, however, remain hidden behind global approaches such as life cycle assessment (LCA), which are generally product-oriented and tend to ignore ecosystem services (ES). This paper aims to propose new decision-making tools for land use planning based on the joint use of ecosystem services assessment (ESA) and territorial Life Cycle Assessment (T-LCA). Within the T-LCA framework, two main types of indicators were quantified. On the one hand, the services provided by land planning scenarios were computed by the ESA by considering provisioning, cultural and regulation ES. On the other hand, environmental impacts were characterized using the Impact World+ Life Cycle Impacts Assessment (LCIA) method.
Two contrasting scenarios and a business as usual scenario (BAU) were studied and compared as a proof of concept. Scenario 1 focused on productive economy by maintaining and diversifying the shellfish farming sector, which is a strong component of the area's social identity. Scenario 2 favoured the development of tourism. Overall, the results indicated that environmental damages varied only slightly between scenarios, with tourism activities (i.e., transport and accommodation) emerging as the primary contributors. In contrast, there were very different profiles in terms of socio-economic benefits depending on the scenario. Provisioning ES were very high in scenario 1, while scenario 2 led to a clear increase in cultural ES. This research emphasizes the importance of developing integrated assessment approaches when creating local planning policies, in order to identify potential trade-offs between environmental impacts and benefits, and local and global issues.

The increasing volume of municipal solid waste (MSW) globally requires sustainable management strategies, especially in resource-constrained regions where landfilling remains predominant due to economic limitations. This study proposes a decision-support model focused on sustainability to guide the choice of technological routes for MSW management, comparing a conventional sanitary landfill with an integrated and innovative biorefinery (2IB), positioned at the top of the waste management hierarchy. The evaluation includes a diagnosis phase, which addressed only the treatment plants, and a simulation phase, which incorporated transportation distances and variations in MSW composition. Both phases were based on the five-sector sustainability model (5SEnSU), here applied for the first time to MSW management systems. Results focused on treatment showed that 2IB performs approximately 15 times better in terms of the sustainability synthetic indicator of the system (SSIS: 0.53) compared to sanitary landfill (SSIS: 8.12). Results from simulations revealed that 2IB remains the more sustainable option for additional transport distances up to 11,000 km/day and for any combination of organic and inorganic waste fraction. The study concludes that the adoption of 2IB should be prioritized in MSW public policies, particularly through intermunicipal consortia, which can facilitate implementation. This study contributes scientifically by assessing, for the first time using the 5SEnSU, the sustainability of an innovative biorefinery for MSW. Practically, it delivers a replicable and adaptable model to help local governments make informed, sustainability-based decisions. It further offers clear operational threshold, on transport distance and waste composition, that can be readily applied in real-world planning and policy.

This work presents a rigorously formulated methodology for directly estimating the vertical subgrade modulus (Ks) in slab foundations, overcoming key deficiencies of conventional indirect and semi-direct approaches. The model integrates elastic half-space theory with multilayer settlement analysis and oedometer-based consolidation mechanics, explicitly incorporating depth of influence and load compensation effects—parameters typically excluded from standard practice. The proposed formulation yields a Ks value of 5.30 MN/m3, closely matching the harmonic mean of established upper (17.82 MN/m3) and lower (2.91 MN/m3) bounds, thereby producing a modulus consistent with elastic energy principles and mechanistically grounded, suitable for advanced soil–structure interaction modeling. A new, application-specific safety coefficient for Ks is introduced, offering a calibrated metric for reliability-based foundation design under spatially variable subsurface conditions. The study implements a life-cycle sustainability assessment across three reinforced concrete slab foundation alternatives, utilizing a hybrid neutrosophic analytic hierarchy process (NAHP-G) in conjunction with the ELECTRE IS multi-criteria decision method. This framework enables integrated evaluation across structural, environmental, and socio-economic dimensions. Results indicate a 2.5-fold enhancement in the social safety index and a 50 % relative improvement in sustainability performance compared with baseline methodologies. The outcomes delineate a unified analytical and decision-making framework for subgrade characterization and foundation optimization, advancing the state of practice in geotechnical design and sustainability integration.

Land degradation is a global ecological and environmental issue to which the drylands with vulnerable socio-ecological systems are particularly sensitive. Ecological restoration is regarded as a vital approach to halt, curb or reverse land degradation. However, the lack of accurate information on land degradation dynamics poses a significant barrier to developing effective restoration strategies. Here, we selected fourteen typical land degradation processes in China's drylands, employed a generalised additive model to identify degradation thresholds and classify degradation states, and analysed degradation trends using the Theil-Sen slope statistic and Mann-Kendall test. We then applied the convergence of evidence method to conduct a comprehensive, multidimensional assessment coupling degradation states and trends, ultimately identifying priority areas for ecological restoration. The results showed that aridification, loss of soil organic carbon, and soil alkalisation are the most widespread forms of land degradation facing China's drylands. 70.33 % of the area is affected by 1 to 7 types of land degradation (mildly degraded state), 25.63 % is affected by 8 to 14 types (severely degraded state), and 4.04 % shows no signs of degradation (non-degraded state). While land degradation across all three states generally exhibits a stable trend, mildly degraded areas showed signs of improvement, whereas severely degraded areas remain at risk of further degradation. Based on the states and trends of land degradation, China's drylands can be categorised into restoration-priority areas (6.79 %), conservation-priority areas (11.74 %), and management-priority areas (81.47 %), each with distinct focus and intervention needs. This study can help decision-makers understand the dynamics of land degradation and develop priority strategies for ecological restoration.

Decentralized environmental management often leads to local protectionism and inconsistent policy enforcement, resulting in strategic regulatory behavior and a failure to address interjurisdictional externalities. This study examines whether centralizing environmental governance helps mitigate these problems, using a vertical management system reform of environmental governance agencies below the province level in Jiangsu Province, China. We analyze the reform's impact by comparing changes in environmental enforcement at jurisdictional borders with those in inland areas. Leveraging novel, geocoded firm-level panel data on environmental inspections, we find that the centralization reform has strengthened enforcement at jurisdictional borders, increasing environmental warnings and penalties on border firms by 10.5 % ∼ 13.4 % relative to inland firms. Our findings suggest that centralizing environmental management improves environmental outcomes by curbing local governments' free-riding behavior and strengthening enforcement efforts.

Our findings suggest that centralizing environmental management improves environmental outcomes by curbing local governments' free-riding behavior and strengthening enforcement efforts.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"118 ","pages":"Article 108328"},"PeriodicalIF":11.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145920766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective utilization of land resources is a global priority and a critical pathway toward achieving the Sustainable Development Goals (SDGs). As the world's most populous developing country, China faces severe challenges from the encroachment of ecological land driven by rapid urbanization and industrialization. The establishment of National Key Ecological Function Zones (NKEFZs) plays a pivotal role in optimizing land resource allocation (LRA) as a spatial regulatory instrument. Drawing on panel data from 1998 Chinese counties spanning 2007 to 2022, this study examines the impact of NKEFZs on LRA, with particular attention to incremental control and stock optimization. The findings show that establishing NKEFZs effectively improves LRA. It increases land-increment control (LIC) by 0.56% and enhances land-stock optimization (LSO) by 5.37%. These effects operate mainly through adjustments in local governments' land-supply strategies and firms' land-use demand. The policy effects are especially pronounced in central and western regions, economically less active areas, regions with stronger regulatory enforcement, and zones designated for water and soil conservation. Moreover, we find that government growth competition weakens the policy's impact on LIC, while a higher level of marketization enhances its effectiveness. Overall, the study offers policy insights for promoting more intensive and efficient land use within NKEFZs and for better coordinating environmental protection with economic development.

Nudge theory proposes that subtle changes in choice presentation can have a profound influence on people's decisions and behaviors. Grounded in this theory, researchers and practitioners started to design and implement ‘green nudges’ that can alter workers' behavior in conducting on-site construction waste management (CWM). However, how exactly such nudges can be designed and implemented remains unclear. This paper explores ‘green nudges’ that can be deployed to boost CWM on site. Instead of developing physical nudges and implementing them, this research adopts the metaverse serious games. Firstly, several green nudge options were developed based on the literature and CWM practices. Their on-site implementations were simulated in metaverse serious games. Next, seventy participants with construction site management experience were randomly assigned to either an experimental group (exposed to green nudges) or a control group (operating under conventional conditions). The Mann-Whitney U tests and XGBoost-based SHAP analyses were conducted to compare the results between the two groups. It is discovered that participants who were exposed to green nudges, such as ‘moral suasion’, ‘simplification’, and ‘social comparison’ with timely feedback, showed improved performance in ‘participation count’, ‘waste collection rate’, and ‘sorting accuracy’ in CWM. Moreover, attitudes, perceived convenience, and emotion were found to significantly influence CWM performance. Waste managers should consciously tap into these green nudges to improve these aspects and ultimately achieve improved CWM performance.
