Solar energy, as a low-carbon energy source, plays a critical role in the global energy transition. While existing studies have examined the impact of SF development on land surface temperature (LST), inconsistent conclusions underscore an urgent need to systematically reveal the spatial heterogeneity of these impacts and their driving factors. Therefore, this study takes 1266 solar farms (SFs) in China as research objects. Based on the Google Earth Engine platform and Landsat satellite data, we revealed the patterns of LST impacts from SF construction and operation. Combined with machine learning methods, we systematically elucidated the spatial heterogeneity characteristics of SF on LST, and simulated the potential future impacts of SF development on LST at the grid scale across China. The results showed that SF development overall caused a significant increase in LST of 0.809 °C (p < 0.001); however, spatial differentiation was highly significant. Specifically, warming dominated in eastern humid zones, cropland land cover types, and small-scale SFs, while cooling prevailed in northwest arid zones, barren land cover types, and large-scale SFs. Macro-scale geoclimatic factors (e.g., air pressure, solar radiation) exhibited the most prominent regulatory effects on LST, followed by ecological and layout factors (e.g., NDVI, SF area). In addition, one of the key findings was that ignoring the construction year of different SFs overestimated their impact on LST, which was being reported for the first time. The research framework can provide methodological extensions for research in similar regions, and the findings can provide theoretical support for the sustainable development of solar energy.

太阳能作为一种低碳能源，在全球能源转型中发挥着至关重要的作用。虽然已有研究考察了顺丰发展对地表温度的影响，但结论不一致，迫切需要系统地揭示这些影响的空间异质性及其驱动因素。因此，本研究以中国1266个太阳能发电场为研究对象。基于谷歌地球引擎平台和Landsat卫星数据，揭示了SF建设和运行对地表温度的影响模式。结合机器学习方法，系统阐述了顺丰发展对地表温度的空间异质性特征，并在网格尺度上模拟了未来中国顺丰发展对地表温度的潜在影响。结果表明，SF发展总体上导致地表温度显著升高0.809°C (p < 0.001)；但空间分异非常显著。其中，东部湿润区、耕地覆盖类型和小尺度森林覆盖区以变暖为主，西北干旱区、荒地覆盖类型和大尺度森林覆盖区以变冷为主。宏观地理气候因子（如气压、太阳辐射）对地表温度的调节作用最为显著，其次是生态因子和布局因子（如NDVI、SF面积）。此外，一个重要的发现是忽略不同SFs的建设年份高估了它们对地表温度的影响，这是第一次被报道。该研究框架可为类似地区的研究提供方法论延伸，研究成果可为太阳能可持续发展提供理论支持。

Large infrastructure projects pose substantial and frequently irreversible threats to biological and cultural diversity. These projects predominantly rely on one-size-fits-all solutions, informed by extractive paradigms that endanger the vitality of social-ecological systems. This tendency towards monotone solutions is epitomised by Environmental Impact Assessments (EIAs). In principle, EIAs should provide the opportunity for fair, accurate, and open-ended evaluation of projects; instead, they are often used instrumentally to facilitate the implementation of decisions already made elsewhere. Building on debates on the integration of social and cultural aspects in EIA, our work seeks to address three core flaws found in conventional EIAs: (1) an inherent bias favoring development projects; (2) an anthropocentric, short-sighted vision of sustainability; and (3) a lack of meaningful participation by affected human communities. In this paper, we introduce the outcomes of a transdisciplinary retreat where academics, practitioners, and activists designed and tested a Co-Creative Relational Impact Assessment Process (CoRIAP), drawing on two archetypal cases in Kenya and Laos. CoRIAP includes: (a) process-oriented components, aimed at transforming EIA from a routine checklist to a purposeful, inclusive, and open-ended procedure; and (b) measurement-oriented components, aimed at providing a framework for identifying relational criteria that are key to the well-being of humans and broader ecosystems, including ethics, emotions, aesthetics, and alternative ways of knowing. This novel protocol complements and broadens existing EIA practice, while providing communities with a tool for self-strengthening and reflection. On a higher level, our work contributes to refining the theoretical basis for integrating social and cultural elements into EIA practice.

大型基础设施项目对生物和文化多样性构成重大且往往不可逆转的威胁。这些项目主要依赖于一刀切的解决方案，以危及社会生态系统活力的采掘模式为依据。这种倾向于单调的解决方案是环境影响评估（eia）的缩影。原则上，环评应提供对项目进行公平、准确和开放式评价的机会；相反，它们往往被用来促进执行其他地方已经作出的决定。基于对环境影响评估中社会和文化因素整合的讨论，我们的工作旨在解决传统环境影响评估中存在的三个核心缺陷：(1)对开发项目的固有偏见；(2)以人类为中心的短视可持续性；(3)受影响的人类社区缺乏有意义的参与。在本文中，我们介绍了跨学科静修的结果，其中学者，从业者和活动家设计并测试了共同创造关系影响评估过程（CoRIAP），借鉴了肯尼亚和老挝的两个原型案例。CoRIAP包括：(a)面向过程的组件，旨在将环境影响评估从例行检查表转变为有目的、包容和开放式的程序；(b)以测量为导向的组件，旨在提供一个框架，用于识别对人类福祉和更广泛的生态系统至关重要的关系标准，包括伦理、情感、美学和其他认识方式。这一新的协议补充和扩大了现有的环境影响评估实践，同时为社区提供了自我加强和反思的工具。在更高层次上，我们的工作有助于完善将社会文化因素融入环境影响评价实践的理论基础。

Concrete production is a major source of carbon emissions, but carbonation of concrete throughout its life is also a natural process that results in the sequestration of atmospheric CO₂ into the concrete. To understand the relationship between emission and sequestrations this study quantifies the carbonation potential of recycled concrete aggregate (RCA) across its full lifecycle, encompassing both service life and end-of-life, including stockpiling, recycling, and secondary use. An Empirical CO₂ Uptake Model for Concrete developed by IVL is used to predict carbonation depths in natural and the recycled concrete utilized as aggregate. This model assesses the carbonation uptake relative to both the CO₂ generated from cement production and from concrete production in a standard bridge structure. The data shows limited carbonation occurs during the primary service life over 100 years, capturing only up to 2.99 % (5.85 kg CO₂/m³) of calcination emission, while secondary applications add up to 2.66 % (5.19 kg CO₂/m³). In contrast, the recycling and stockpiling phase achieves a higher rate of carbonation over a 12-month period, ranging from 31 to 65 % (61–128 kg CO₂/m³), depending on stockpile configuration and duration. Shallow, spread-out stockpiles maximize CO₂ absorption by increasing surface exposure and airflow. Dust particles fully carbonate within weeks (31 % of calcination emission), whereas larger particles carbonate progressively over time. Secondary use of RCA in new concrete further enhances its carbon sink potential due to its residual reactivity and increased porosity. Overall, concrete demonstrates substantial carbonation potential, with total CO₂ uptake ranging from 35 % to 68 % of calcination emission.

混凝土生产是碳排放的主要来源，但混凝土在其整个生命周期中的碳化也是一个自然过程，导致大气中的二氧化碳被隔离到混凝土中。为了了解排放和封存之间的关系，本研究量化了再生混凝土骨料（RCA）在其整个生命周期内的碳化潜力，包括使用寿命和报废寿命，包括储存、回收和二次利用。IVL开发的混凝土经验CO₂吸收模型用于预测用作骨料的天然和再生混凝土的碳化深度。该模型评估了在标准桥梁结构中，相对于水泥生产和混凝土生产产生的二氧化碳的碳化吸收。数据显示，在100年以上的主要使用寿命期间，碳化作用有限，仅捕获了高达2.99% （5.85 kg CO2/m3）的煅烧排放，而二次应用合计高达2.66% （5.19 kg CO2/m3）。相比之下，回收和储存阶段在12个月的时间内实现了更高的碳化率，范围从31%到65%（61-128千克二氧化碳/立方米），具体取决于储存配置和持续时间。浅层铺开的储层通过增加表面暴露和气流来最大限度地吸收二氧化碳。粉尘颗粒在几周内完全碳酸盐化（煅烧排放的31%），而较大的颗粒随着时间的推移逐渐碳酸盐化。二次使用RCA在新混凝土进一步提高其碳汇潜力，由于其残余的反应性和增加的孔隙率。总体而言，混凝土具有巨大的碳化潜力，其二氧化碳吸收总量占煅烧排放总量的35%至68%。

Synergy refers to the degree to which the same measure produces simultaneous reductions in CO₂ and pollutant emissions at the industrial parks. Assessing the synergy can inform key management policies and measures critical for advancing emission reduction efforts. However, the overall impact of industrial symbiosis on the synergy remains unclear due to the lack of a systematic quantitative method for embedding network topology into synergy measurement. Therefore, we proposed the Complex Network Analysis-Synergistic Assessment method (CNA-SA), which integrates the symbiotic relationships among enterprises within the industrial chain to assess the contribution of industrial symbiosis to synergy quantitatively. By combining CNA-SA with scenario analysis, this study also quantitatively compares the relative merits of different symbiosis modes that promote synergy. The results from typical industrial parks indicate that industrial symbiosis among enterprises can enhance synergy by at least 5.49 % to 102.63 %. Furthermore, the synergy of CO₂ and pollutant reductions was more strongly influenced by the integrity of the industrial chain than its diversity. Extending the existing industrial chain will increase the synergy from 0.67 to at least 0.80, yielding greater improvements with less effort compared to establishing new industrial chains. These results support ecologically guided park design, help managers identify opportunities for emission reduction and development pathways, and provide technical support for achieving synergy of CO₂ and pollutant reductions.

协同效应指的是同一措施同时减少工业园区的二氧化碳和污染物排放量的程度。评估协同作用可以为推进减排工作至关重要的关键管理政策和措施提供信息。然而，由于缺乏将网络拓扑嵌入协同效应测量的系统定量方法，产业共生对协同效应的整体影响尚不清楚。为此，我们提出了复杂网络分析-协同评价方法（CNA-SA），通过整合产业链内企业间的共生关系，定量评价产业共生对协同的贡献。通过结合CNA-SA和情景分析，本研究还定量比较了促进协同的不同共生模式的相对优势。典型工业园区的研究结果表明，企业间的产业共生能使协同效应提高至少5.49% ~ 102.63%。此外，二氧化碳减排和污染物减排的协同效应受产业链完整性的影响大于产业链多样性的影响。延长现有产业链将使协同效应从0.67提高到至少0.80，比建立新的产业链更省力。这些结果为生态引导型公园设计提供了支持，帮助管理者识别减排机会和发展路径，并为实现二氧化碳减排和污染物减排的协同效应提供了技术支持。

The construction sector is a major contributor to climate change and resource depletion, responsible for over 36 % of global final energy use and nearly half of all raw material consumption. Addressing structural systems' environmental and social sustainability is a critical challenge for the transition toward a circular and low-carbon built environment. Among structural elements, floor slabs are particularly critical due to their intensive use of concrete and steel. This study develops an integrated, data-driven framework that combines multivariate structural modeling with environmental and social life cycle assessment (E-LCA and S-LCA), explicitly describing the methodological approach before results are introduced. Leveraging empirical data from 67 real buildings, the framework generates robust pre-dimensioning guidelines that support early-stage decision-making in sustainable construction. Results demonstrate substantial material and impact reductions: concrete and steel use decrease by 23–33 % and up to 29 %, respectively, leading to average endpoint environmental impact reductions of 25 % and global warming potential decreases of 24 %, reaching 30 % for six-meter spans. S-LCA highlights social risk reductions up to 20 % in the Workers and Local Community categories, reflecting safer and more socially responsible construction practices. By integrating advanced multivariate modeling with comprehensive life cycle assessment, this research delivers a decision-oriented tool that accelerates the adoption of circular, low-carbon construction systems. The revised abstract also highlights the policy and management implications: the findings provide actionable insights for engineers, regulators, and policymakers, supporting the development of building codes, resource-efficient design guidelines, and climate-aligned strategies for the construction sector. Ultimately, this work promotes a resilient and sustainable built environment, advancing circular economy principles and the United Nations Sustainable Development Goals (SDGs).

建筑业是造成气候变化和资源枯竭的主要因素，占全球最终能源消耗的36%以上，占所有原材料消耗的近一半。解决结构系统的环境和社会可持续性是向循环低碳建筑环境过渡的关键挑战。在结构元素中，楼板尤其重要，因为它们大量使用混凝土和钢材。本研究开发了一个集成的、数据驱动的框架，将多变量结构建模与环境和社会生命周期评估（E-LCA和S-LCA）相结合，在介绍结果之前明确描述了方法方法。利用来自67座真实建筑的经验数据，该框架生成了强大的预维度指导方针，支持可持续建筑的早期决策。结果显示了大量的材料和影响的减少：混凝土和钢材的使用分别减少了23 - 33%和高达29%，导致平均端点环境影响减少25%，全球变暖潜势减少24%，6米跨度达到30%。S-LCA强调，在工人和当地社区类别中，社会风险降低了20%，反映了更安全和更具社会责任的建筑实践。通过将先进的多元建模与综合生命周期评估相结合，本研究提供了一个决策导向的工具，加速了循环低碳建筑系统的采用。修订后的摘要还强调了政策和管理方面的影响：研究结果为工程师、监管机构和政策制定者提供了可操作的见解，为建筑行业制定建筑规范、资源节约型设计指南和与气候相关的战略提供了支持。最终，这项工作促进了一个有弹性和可持续的建筑环境，推进循环经济原则和联合国可持续发展目标（sdg）。

Urban green space (UGS) serves to mitigate ambient pollutant concentrations through adsorption and dispersion effects while providing carbon sequestration via photosynthesis, contributing synergistically to urban climate and air quality improvement. This study quantifies this synergistic role by evaluating the UGS-attributed reduction in PM_2.5-related health impacts, the UGS-produced carbon sequestration, and the socioeconomic value of these co-benefits, using Chinese cities as a case study. From 2008 to 2022, UGS collectively prevented an estimated 179.34 thousand PM_2.5-related premature deaths and sequestered 349.81 million tCO₂e, corresponding to socioeconomic values of 694.69 and 314.94 billion CNY, respectively. Driven by urbanization and the expansion of UGS in China, UGS-attributed health benefits and carbon sequestration have shown steady growth over the past 15 years. Furthermore, this study evaluates the UGS investment-benefit ratio, environmental Gini coefficient, and offsetting rate (relative to city-level PM_2.5-related health impacts and CO₂ emissions), revealing inequalities in UGS-related environmental investment, benefits, and responsibilities across cities. The identification of associated socioeconomic factors indicated that urbanization progress exerted a complex influence on the capacity of UGS to deliver environmental health and climate co-benefits.

城市绿地（UGS）通过吸附和分散作用降低环境污染物浓度，同时通过光合作用提供碳固存，对城市气候和空气质量的改善有协同作用。本研究以中国城市为例，通过评估ugs对pm2.5相关健康影响的减少、ugs产生的碳固存以及这些共同效益的社会经济价值，量化了这种协同作用。2008年至2022年，UGS共预防了约17934万例与pm2.5相关的过早死亡，封存了3.4981亿吨二氧化碳当量，分别产生了6946.9亿元和3149.4亿元的社会经济价值。在中国城市化和UGS扩张的推动下，UGS带来的健康效益和碳固存在过去15年中稳步增长。此外，本研究还评估了UGS的投资效益比、环境基尼系数和抵消率（相对于城市层面的pm2.5相关健康影响和二氧化碳排放），揭示了UGS相关环境投资、效益和责任在城市之间的不平等。相关社会经济因素的确定表明，城市化进程对UGS提供环境健康和气候共同效益的能力产生了复杂的影响。UGS作为城市绿色基础设施的组成部分和城市化的产物，在一定程度上抵消了城市开发建设对环境的负面影响。对UGS衍生的协同效益进行全面、系统的评估，可以为UGS空间规划提供信息，支持绿色城市化、美丽中国发展和实现可持续发展目标11。

In the context of globalization, biodiversity loss has become a significant challenge for global sustainable development, and its impact on human health cannot be ignored. Based on data from the Global Biodiversity Information Facility and the World Bank Development Indicators database, this paper employs a cross-national panel dataset of 174 countries from 2000 to 2021 to examine the impact of biodiversity loss on human health. Further analysis elucidates two potential pathways through nutritional and environmental quality perspectives. The findings reveal that biodiversity loss can negatively impact human health. This paper only tests two such pathways regarding mechanisms, finding that biodiversity loss can reduce human health by exacerbating malnutrition and degrading environmental quality. Additionally, biodiversity loss has a more pronounced impact on health in low-income countries and those with higher aging populations, reflecting differences in vulnerability across varying economic and social contexts. Based on these findings, this study recommends that governments worldwide strengthen biodiversity conservation efforts, enhance nutritional security, and improve environmental governance systems to mitigate the negative impacts of biodiversity loss on human health and promote harmonious coexistence between humans and nature.

在全球化背景下，生物多样性丧失已成为全球可持续发展面临的重大挑战，对人类健康的影响不容忽视。根据全球生物多样性信息基金和世界银行发展指标数据库的数据，本文采用2000年至2021年174个国家的跨国面板数据集，研究生物多样性丧失对人类健康的影响。进一步的分析从营养和环境质量的角度阐明了两种可能的途径。研究结果表明，生物多样性的丧失会对人类健康产生负面影响。本文只测试了这两种途径的机制，发现生物多样性丧失可以通过加剧营养不良和降低环境质量来降低人类健康。此外，在低收入国家和人口老龄化程度较高的国家，生物多样性丧失对健康的影响更为明显，反映出不同经济和社会背景下脆弱性的差异。研究建议各国政府应加强生物多样性保护，加强营养安全，完善环境治理体系，以减轻生物多样性丧失对人类健康的负面影响，促进人与自然的和谐共处。

Photovoltaic (PV) systems are central to global decarbonization, but their assessed environmental impacts vary due to inconsistencies in life cycle assessment (LCA) methodologies. These differences hinder comparability and the development of a transparent sustainability framework. To address this issue, this review systematically synthesizes PV LCA studies across five continents. The analysis highlights variations in system boundaries, functional units, data quality, and regulatory frameworks, revealing that methodological coherence is strongly shaped by regional policy and data infrastructure. Europe, supported by stringent regulations and localized inventories, demonstrates high methodological alignment. In contrast, Africa and Latin America face major data gaps, with over 90 % of studies relying on non local inventories, creating uncertainty in the results. Building on these findings, this study proposes key harmonization strategies, including enhanced transparency, the adoption of standardized guidelines such as IEA PVPS Task 12, and the targeted development of regional life cycle inventory databases. These measures provide policymakers, industry, and researchers with a practical framework to strengthen the reliability and comparability of PV sustainability assessments, supporting solar energy's role in a low carbon future. Future research should prioritize the expansion of localized datasets and the integration of dynamic LCA approaches to capture rapid technological evolution and circular economy principles.

光伏（PV）系统是全球脱碳的核心，但由于生命周期评估（LCA）方法的不一致性，其评估的环境影响各不相同。这些差异阻碍了可比性和透明可持续性框架的发展。为了解决这一问题，本文系统地综合了五大洲的PV - LCA研究。分析强调了系统边界、功能单元、数据质量和监管框架的差异，揭示了方法一致性在很大程度上受到区域政策和数据基础设施的影响。欧洲在严格的法规和本地化库存的支持下，显示出高度的方法一致性。相比之下，非洲和拉丁美洲面临着重大的数据缺口，超过90%的研究依赖于非当地的库存，造成了结果的不确定性。在这些发现的基础上，本研究提出了关键的协调策略，包括提高透明度，采用标准化指南，如IEA PVPS任务12，以及有针对性地开发区域生命周期清单数据库。这些措施为政策制定者、行业和研究人员提供了一个实用的框架，以加强光伏可持续性评估的可靠性和可比性，支持太阳能在低碳未来中的作用。未来的研究应优先考虑本地化数据集的扩展和动态LCA方法的整合，以捕捉快速的技术演变和循环经济原则。

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.

助推理论认为，选择呈现的细微变化会对人们的决策和行为产生深远的影响。基于这一理论，研究人员和实践者开始设计和实施“绿色推动”，以改变工人在现场建筑垃圾管理（CWM）中的行为。然而，这种推动究竟如何设计和实施仍不清楚。本文探讨了可以部署的“绿色推动”，以促进现场的CWM。本研究采用了虚拟严肃游戏，而不是开发和执行物理推动。首先，在文献和CWM实践的基础上，提出了几种绿色推动方案。在虚拟世界严肃游戏中模拟了他们的现场实施。接下来，70名有建筑工地管理经验的参与者被随机分配到实验组（接触绿色轻推）和对照组（在常规条件下操作）。采用Mann-Whitney U检验和基于xgboost的SHAP分析来比较两组之间的结果。研究发现，在“道德劝说”、“简化”、“社会比较”等及时反馈的绿色推动下，参与者在CWM中的“参与次数”、“废物收集率”和“分类准确性”方面的表现有所提高。此外，态度、感知便利和情绪显著影响CWM绩效。废物管理人员应有意识地利用这些绿色推动来改善这些方面，并最终实现改善CWM的性能。

From global to domestic scales: Do changes in industrial divisions burden sub-national emission reduction? 从全球到国内：产业分工的变化会给地方减排带来负担吗？

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.

复杂的国际形势威胁到全球贸易，强调了国内产业分工的作用。然而，国内分化的蓬勃发展所带来的经济联动变化是否会给减排带来负担却没有得到足够的重视，尽管这对碳中和至关重要。为了填补这一空白，我们开发了一个新的分析框架，通过构建全球-中国省嵌套多区域投入产出（NMRIO）表，实现了全球、区域和次国家尺度的综合分析。我们试图确定国内分工是否会给地方减排带来更大的负担，以及与参与全球分工相比，国内分工是如何发挥作用的。我们发现，在研究期间，各省对国内区划的参与呈上升趋势。但与全球分工相比，国内产业分工对碳排放的增加作用更强。这种排放增长的主要驱动因素是生产规模的扩大和总体产业内部分部门结构的碳化。技术驱动的碳排放强度降低对于缓解国内区域内，特别是中西部省份与东部地区之间的排放上升至关重要。全球区域分析表明，与欧盟和北美国家的分裂会增加碳排放，而与一带一路国家的分裂没有显著的排放效应。此外，在全球分工中，垂直专业化比例越高，有助于缓解各省的碳排放，而在国内分工中，位置越下游，可以更显著地缓解分工驱动的碳排放。
