The Paris Agreement's goal of limiting global warming to well below 2 °C, ideally 1.5 °C, places significant emphasis on Carbon Dioxide Removal (CDR) technologies. However, the global landscape for CDR deployment remains uneven, with significant disparities in technological capacity, economic readiness, and regional ambition. This study investigates how limited access to CDR technologies could exacerbate global economic inequality under a 1.5 °C pathway. Using the Global Change Analysis Model (GCAM v6.0), six scenarios ranging from unrestricted CDR availability to constrained deployment are evaluated. Our findings reveal that constrained CDR availability significantly increases median global carbon prices, rising from $588/tCO₂ under the full CDR portfolio scenario to $937/tCO₂ by 2055 in the most restrictive scenario. By 2100, some regions face prices exceeding $3000/tCO₂, underscoring stark regional inequalities. These elevated carbon prices could deepen economic disparities—particularly in developing nations and fossil fuel-dependent economies. Furthermore, constrained CDR availability could also amplify inequalities in energy and food security, disproportionately affecting poorer regions. The study underscores the need for equitable CDR access to support a just global transition to a low-carbon future, offering valuable insights for policymakers designing more equitable climate strategies.

《巴黎协定》的目标是将全球变暖控制在远低于2°C的范围内，理想情况下是1.5°C，这非常强调二氧化碳去除（CDR）技术。然而，CDR部署的全球格局仍然不平衡，在技术能力、经济准备程度和区域雄心方面存在重大差异。本研究探讨了在升温1.5°C的路径下，有限的CDR技术获取如何加剧全球经济不平等。使用全局变化分析模型（GCAM v6.0），评估了从无限制CDR可用性到受限部署的六个场景。我们的研究结果表明，受限制的CDR可得性显著提高了全球碳价格中位数，从完全CDR组合情景下的588美元/吨二氧化碳上升到2055年最受限制情景下的937美元/吨二氧化碳。到2100年，一些地区的二氧化碳价格将超过3000美元/吨，突显出严重的地区不平等。碳价格的上涨可能会加深经济差距，尤其是在发展中国家和依赖化石燃料的经济体。此外，CDR供应受限还可能加剧能源和粮食安全方面的不平等，对较贫困地区造成不成比例的影响。该研究强调了公平获取CDR的必要性，以支持全球向低碳未来的公正过渡，为制定更公平的气候战略的政策制定者提供了宝贵的见解。

Artificial intelligence is rapidly transforming technology in society and is increasingly seen as a critical tool for addressing complex global challenges, including the United Nations Sustainable Development Goals. These seventeen goals, grouped into societal, economic, and environmental domains, present both opportunities and risks when intersecting with artificial intelligence. While artificial intelligence has the capacity to accelerate sustainable development, it may also exacerbate inequalities, environmental degradation, or other unintended harms if ethical concerns are not adequately addressed. Despite a growing body of research on ethical frameworks for artificial intelligence, there remains a lack of empirical understanding of how users perceive its potential, its ethical implications, and the principles that should guide its deployment in sustainable development contexts. It is natural to raise the questions: How do Sustainable Development Goals and goal groups affect these user perceptions? To answer these questions, we conducted a comprehensive human-subject study examining variations in user perceptions across 17 Sustainable Development Goals and three overarching goal groups. Our findings reveal substantial variation in perceived potential and ethical priorities depending on the specific goal, while the perceived importance of ethical considerations remains consistent across goal groups. The novelty of this study lies in combining the AI–SDG context with empirical and perception-based evidence, and our results highlight the necessity of incorporating user perspectives into the design and governance of artificial intelligence systems to ensure ethically aligned and socially accepted progress toward sustainable development.

人工智能正在迅速改变社会中的技术，并日益被视为解决复杂全球挑战的关键工具，包括联合国可持续发展目标。这17个目标分为社会、经济和环境领域，在与人工智能交叉时，既带来了机遇，也带来了风险。虽然人工智能有能力加速可持续发展，但如果伦理问题得不到充分解决，它也可能加剧不平等、环境退化或其他意想不到的危害。尽管关于人工智能伦理框架的研究越来越多，但对于用户如何看待其潜力、其伦理影响以及在可持续发展背景下指导其部署的原则，仍然缺乏经验上的理解。人们自然会提出这样的问题：可持续发展目标和目标群体如何影响这些用户的看法？为了回答这些问题，我们进行了一项全面的人类受试者研究，研究了17个可持续发展目标和三个总体目标组中用户感知的变化。我们的研究结果显示，根据具体目标，感知到的潜力和道德优先级存在很大差异，而感知到的道德考虑的重要性在目标群体中保持一致。本研究的新颖之处在于将人工智能可持续发展目标背景与经验和基于感知的证据相结合，我们的研究结果强调了将用户视角纳入人工智能系统设计和治理的必要性，以确保在道德上与社会一致，并为可持续发展所接受。

Assessing the environmental performance of systems from an absolute perspective is a recent trend for achieving a sustainable world. We present a framework for evaluating different power generation scenarios for Chile and their effects in terms of absolute sustainability performance. In this context, seven energy transition scenarios to 2060 are analyzed, including a business-as-usual scenario, high fossil fuel prices, climatic variability in terms of extreme droughts, a fully renewable system, different levels of hydrogen production, and a conservative case considering a low growth in electricity demand. The scenarios were modeled using the Open Source Energy Modeling System (OSeMOSYS), while environmental impacts were calculated using life cycle assessment methodology for five midpoint categories: global warming, freshwater eutrophication, marine eutrophication, ozone depletion, and water consumption. The planetary boundaries were calculated following a top-down approach under different downscaling-upscaling methods. Electricity demand ranges from 121 TWh in the conservative scenario to 353 TWh in the case of high (2.72 Mton) hydrogen production by 2060. For the remaining scenarios, electricity demand is around 205 TWh, aligned with projections from the Chilean government. In terms of environmental impacts, all prospective scenarios showed an average reduction of 66 % across all evaluated categories, shifting the main contributor to these impacts from fossil fuels (baseline scenario) to photovoltaic and wind energy. Although none of the scenarios fully operate within the safe operating space of the planetary boundaries, a fully renewable matrix and a conservative increase in electricity demand are identified as the most favorable scenarios. To operate within the planetary boundaries across all categories, the Chilean electricity mix must not only increase the share of renewable sources but also reduce per capita electricity consumption by up to one-half by 2060, relying exclusively on renewable sources. This research is expected to have implications for policymaking and research on the transition of power generation towards the climate targets of Chile.

从绝对角度评估系统的环境绩效是实现可持续世界的最新趋势。我们提出了一个框架，用于评估智利不同的发电方案及其在绝对可持续性表现方面的影响。在此背景下，分析了到2060年的7种能源转型情景，包括一切照旧情景、化石燃料价格高企情景、极端干旱方面的气候变化情景、完全可再生系统情景、不同水平的氢气生产情景，以及考虑到电力需求低增长的保守情景。这些情景使用开源能源建模系统（OSeMOSYS）进行建模，而环境影响则使用生命周期评估方法计算五个中点类别：全球变暖、淡水富营养化、海洋富营养化、臭氧消耗和水消耗。采用自顶向下的方法在不同的缩尺-放大方法下计算行星边界。电力需求范围从保守情景下的121太瓦时，到2060年氢气产量高（2.72万吨）时的353太瓦时。对于剩余的情景，电力需求约为205太瓦时，与智利政府的预测一致。就环境影响而言，在所有评估类别中，所有预期情景显示平均减少66%，将这些影响的主要来源从化石燃料（基线情景）转移到光伏和风能。虽然没有一种情况完全在地球边界的安全运行空间内运行，但完全可再生矩阵和电力需求的保守增长被认为是最有利的情况。为了在所有类别的地球边界内运行，智利的电力结构不仅必须增加可再生能源的份额，而且还必须在2060年之前将人均用电量减少一半，完全依赖可再生能源。这项研究预计将对智利气候目标发电转型的政策制定和研究产生影响。

Autonomous cars are increasingly promoted as transformative technologies for urban mobility, yet their sustainability implications remain contested. Existing studies often focus on isolated aspects like environmental, social, or economic implications without providing an integrated perspective. This study addresses this gap by systematically reviewing existing review papers on this topic through the Triple Bottom Line (TBL) framework. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, 49 review articles published between 2009 and 2024 were identified, screened, and analysed. The results highlight that environmental benefits mainly stem from improved traffic efficiency, optimized driving behaviour, and reduced emissions, especially when combined with electrification. However, rebound effects, resource-intensive production, and unregulated usage may limit net gains. Socially, autonomous cars promise improved safety and greater mobility access for elderly and disabled populations, yet concerns about affordability, trust, labour displacement, and ethical dilemmas persist. Economically, they offer potential cost reductions, productivity gains, and new service models, but high capital costs, regulatory uncertainty, and limited evidence on long-term viability constrain widespread adoption. Overall, the TBL framework reveals strong synergies - such as shared autonomous cars enhancing both environmental and social outcomes - alongside trade-offs where benefits in one domain may create risks in another. The study concludes that the sustainability of these vehicles depends less on technological performance than on governance, deployment strategies, and societal acceptance. Future research should prioritize longitudinal analyses of pilot projects, cross-pillar trade-off assessments, and regionally grounded perspectives beyond high-income contexts.

自动驾驶汽车作为城市交通的变革性技术越来越受到推崇，但其可持续性影响仍存在争议。现有的研究往往侧重于孤立的方面，如环境、社会或经济影响，而没有提供一个综合的观点。本研究通过“三重底线”（Triple Bottom Line， TBL）框架系统地回顾了有关该主题的现有评论论文，从而解决了这一差距。使用系统评价和荟萃分析首选报告项目（PRISMA）协议，对2009年至2024年间发表的49篇综述文章进行了识别、筛选和分析。研究结果强调，环境效益主要来自交通效率的提高、驾驶行为的优化和排放的减少，尤其是在与电气化相结合的情况下。然而，反弹效应、资源密集型生产和不受管制的使用可能会限制净收益。从社会角度来看，自动驾驶汽车有望提高安全性，为老年人和残疾人提供更大的出行便利，但人们对可负担性、信任、劳动力转移和道德困境的担忧仍然存在。从经济上讲，它们提供了潜在的成本降低、生产率提高和新的服务模式，但高昂的资本成本、监管的不确定性以及有限的长期可行性证据限制了它们的广泛采用。总体而言，TBL框架揭示了强大的协同效应——比如共享自动驾驶汽车提高了环境和社会结果——以及权衡，一个领域的利益可能会给另一个领域带来风险。该研究的结论是，这些车辆的可持续性取决于管理、部署策略和社会接受度，而不是技术性能。未来的研究应优先考虑试点项目的纵向分析、跨支柱权衡评估以及高收入背景之外的区域视角。

Various recycling technologies are emerging to implement circular economy in plastics supply chain systems. However, the environmental and socio-economic trade-offs of plastics in circular economy are not well understood at a systems level. Particularly, quantifying these trade-offs as a function of end-of-life (EOL) management decisions, including transition of recycling technologies, systems level metrics such as circularity, recycled content, and the need for fossil-derived plastics are not well understood. The present study addressed these research gaps by applying a systems analysis modeling approach that utilizes material flow analysis, life cycle assessment, socio-economic data, and system optimization techniques for polyethylene terephthalate (PET) packaging supply chains in the United States. Pareto-front trade-offs between conflicting environmental and socio-economic impacts as well as those between socio-economic impacts and circularity were explored using the epsilon constraint method. The Pareto-front trade-off analysis revealed the transition of EOL management strategies for PET packaging systems, including changes in selection of recycling technologies, to aid decision making process by quantifying studied system metrics. Transitioning from environmentally optimal to socio-economically optimal systems led to increased employment (by 17 %), wages (by 26 %), and revenues (by 6 %) but also led to increased global warming potential (GWP; by 65 %), energy consumption (by 59 %), and reliance on fossil PET in the system (by 78 %). Finally, the results show that there is not a unique set of recycling technologies to achieve a sustainable circular economy of PET packaging system, instead it depends on the decision maker's objectives and targeted metrics of the system.

为了在塑料供应链系统中实现循环经济，各种回收技术正在兴起。然而，塑料在循环经济中的环境和社会经济权衡在系统层面上还没有得到很好的理解。特别是，将这些权衡作为报废（EOL）管理决策的功能进行量化，包括回收技术的过渡、循环度、回收含量等系统级指标以及对化石衍生塑料的需求，目前还没有得到很好的理解。本研究通过应用系统分析建模方法解决了这些研究空白，该方法利用了美国聚对苯二甲酸乙二醇酯（PET）包装供应链的物料流分析、生命周期评估、社会经济数据和系统优化技术。利用epsilon约束方法探讨了环境和社会经济影响之间的帕累托前权衡，以及社会经济影响和循环之间的权衡。帕累托前权衡分析揭示了PET包装系统EOL管理策略的转变，包括回收技术选择的变化，通过量化所研究的系统指标来帮助决策过程。从环境最优系统向社会经济最优系统的过渡导致了就业（17%）、工资（26%）和收入（6%）的增加，但也导致了全球变暖潜能值（GWP）增加65%，能源消耗增加59%，以及系统中对化石PET的依赖增加78%。最后，研究结果表明，并没有一套独特的回收技术来实现PET包装系统的可持续循环经济，而是取决于决策者的目标和系统的针对性指标。

From sustainability to health: Investigating the halo effect in food consumption behavior 从可持续发展到健康：调查食品消费行为中的光环效应

Research has identified a “halo effect” in consumer perceptions, whereby sustainable products are often seen as healthier than conventional alternatives. When consumers perceive a food product as sustainable, they are more likely to associate it with health benefits as well. This study investigates the presence of this sustainability-halo effect by examining the relationship between consumer sensitivity to sustainable eating and the choices consumers make in relation to healthy food. Specifically, we assess whether sensitivity to sustainability in food consumption enhances sensitivity to healthy eating, attitudes toward healthy foods, and purchase intentions. Additionally, we also examine the potential correlation between sensitivity to healthy eating and sensitivity to sustainable eating. To test those relationships, we applied an extended conceptual model of the intention to buy healthy products, sending a structured questionnaire to a sample of 1100 respondents. The data were analyzed using the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach. The findings confirm the existence of a sustainability-halo effect, demonstrating that greater sensitivity to sustainable eating positively influences attitudes toward healthier food choices and the intention to purchase healthier food products. The results also show that the two variables, sensitivity to healthy eating and sensitivity to sustainable eating, are positively correlated. This effect underscores the interconnected nature of sustainability and health-conscious consumption, suggesting that promoting one aspect may naturally reinforce the other. These insights have significant implications for policy development and dietary guidelines, advocating for an integrated approach to health and sustainability rather than treating them in isolation.

研究已经确定了消费者观念中的“光环效应”，即可持续产品通常被视为比传统替代品更健康。当消费者认为一种食品具有可持续性时，他们更有可能将其与健康益处联系起来。本研究通过考察消费者对可持续饮食的敏感性与消费者对健康食品的选择之间的关系来调查这种可持续性光环效应的存在。具体而言，我们评估食品消费对可持续性的敏感性是否会增强对健康饮食的敏感性、对健康食品的态度和购买意愿。此外，我们还研究了对健康饮食的敏感性和对可持续饮食的敏感性之间的潜在相关性。为了检验这些关系，我们应用了购买健康产品意愿的扩展概念模型，向1100名受访者发送了一份结构化问卷。采用偏最小二乘结构方程建模（PLS-SEM）方法对数据进行分析。研究结果证实了可持续性光环效应的存在，表明对可持续饮食的更大敏感性对健康食品选择的态度和购买健康食品的意愿产生了积极影响。结果还表明，对健康饮食的敏感性和对可持续饮食的敏感性这两个变量呈正相关。这一效应强调了可持续性和注重健康的消费之间相互联系的本质，表明促进一个方面自然会加强另一个方面。这些见解对政策制定和饮食指南具有重大影响，倡导对健康和可持续性采取综合办法，而不是孤立地对待它们。此外，这一发现为食品生产商和营销商提供了一个战略机会，使其在宣传中结合可持续性和营养，促进具有健康意识和对环境负责的消费行为。

The decommissioning of wind turbines is expected to generate large volumes of composite wind turbine blade (WTB) waste that should be handled properly to avoid negative effects on the environment. Despite the growing interest in sustainable life cycle management (LCM) strategies applicable to WTBs, circularity indicators are still rarely used to support decision-making processes. This study addresses this gap by evaluating the scope and practical applicability of circularity indicators across WTB-LCM pathways, stages, and processes. A systematic literature review was conducted covering 158 peer-reviewed papers and identifying 120 circularity indicators, which were subsequently screened using three complementary matrices (extended RACER, circular composite design, and wind sector-specific criteria). This process led to the selection of 13 indicators considered most relevant to the wind industry. Although no single indicator comprehensively captures circularity across all stages and dimensions, the Materials Efficiency Metric was identified as the most suitable for the beginning and middle stages of the life cycle, while the Carbon Footprint Formula was considered most appropriate for the end-of-life stage. Nonetheless, both exhibit relevant limitations for decision-support in practice, as none of the selected indicators fully captures composite-specific quality parameters, such as fibre degradation, resin compatibility, or the potential for reintegration into high-value applications. Building on these findings, the study identifies three main directions for future research: (i) the development of circularity indicators that incorporate underlooked life cycle stages, such as installation, operation and maintenance; (ii) the integration of material quality parameters, such as fibre integrity and resin compatibility, into the design of new indicators; and (iii) the analysis of empirical case studies to determine the maximum circularity performance that could be achieved across the LCM of WTB, in order to support the development of circular innovations. These areas are essential for advancing more comprehensive, system-level assessments and supporting effective strategies for the sustainable energy transition.

风力涡轮机的退役预计会产生大量的复合风力涡轮机叶片（WTB）废物，应妥善处理，以避免对环境产生负面影响。尽管人们对适用于wtb的可持续生命周期管理（LCM）战略越来越感兴趣，但循环指标仍然很少用于支持决策过程。本研究通过评估循环指标在WTB-LCM途径、阶段和过程中的范围和实际适用性来解决这一差距。对158篇同行评议论文进行了系统的文献综述，并确定了120个循环指标，随后使用三个互补矩阵（扩展RACER、循环复合设计和风电行业特定标准）进行筛选。这一过程选出了13个被认为与风电行业最相关的指标。虽然没有一个单一的指标能全面反映所有阶段和维度的循环度，但材料效率指标被认为是最适合生命周期的开始和中期阶段的，而碳足迹公式被认为是最适合生命周期的结束阶段的。然而，在实践中，这两种指标在决策支持方面都表现出相关的局限性，因为所选指标中没有一种能够完全捕获复合材料特定的质量参数，例如纤维降解、树脂相容性或重新融入高价值应用的潜力。在这些发现的基础上，研究确定了未来研究的三个主要方向：(i)发展循环指标，包括未被忽视的生命周期阶段，如安装、操作和维护；（ii）将纤维完整性和树脂相容性等材料质量参数纳入新指标的设计；（iii）实证案例分析，以确定在WTB的LCM中可以实现的最大循环性能，以支持循环创新的发展。这些领域对于推进更全面的系统级评估和支持可持续能源转型的有效战略至关重要。

Beyond the life cycle: assessing business models for the circular economy through life-cycle-based methodologies 超越生命周期：通过基于生命周期的方法评估循环经济的商业模式

Although Life Cycle Assessment (LCA) is widely used in the literature to quantify the impact of products designed according to circularity principles, the analysis of circular business models (CBMs) remains a niche topic. In recent years, some empirical studies have highlighted the urgency of addressing this issue; however, the literature remains fragmented, and a more structured approach is needed for further progress.

This paper aims to fill this gap through a systematic literature review of 60 studies that combine LCA and life-cycle-based (LC-based) methodologies with other methods to assess the environmental sustainability of CBMs. The findings reveal that most studies rely on conventional LCA, which is frequently combined with Life Cycle Costing (LCC) and other qualitative or quantitative methods. There is also growing interest in hybrid and emerging approaches such as Business Model LCA (BM-LCA). LC-based methodologies are often used to compare the environmental impacts of linear business models (BM) and CBMs or to guide the transition from linear BMs toward the design of new CBMs. Particular emphasis is also placed on adopting CBMs such as product service systems, CBMs that extend product lifespan or industrial symbiosis, rather than CBMs focused on using circular materials. A comprehensive coverage across a wide range of sectors emerges.

The study's implications are significant for both researchers and managers. For researchers, the review highlights the need for standardisation efforts to refine tools for assessing CBMs. For managers, the review offers an 8-step operational framework to conduct LC-based analyses for CBM implementation.

尽管生命周期评估（LCA）在文献中被广泛用于量化根据循环原则设计的产品的影响，但循环商业模式（CBMs）的分析仍然是一个小众话题。近年来，一些实证研究强调了解决这一问题的紧迫性；然而，文献仍然是碎片化的，需要一个更结构化的方法来取得进一步的进展。本文旨在通过对60项研究的系统文献综述来填补这一空白，这些研究将生命周期分析和基于生命周期的方法与其他方法相结合，以评估信任措施的环境可持续性。研究结果表明，大多数研究都依赖于传统的生命周期成本分析，并经常与生命周期成本计算（LCC）和其他定性或定量方法相结合。人们对商业模式LCA （BM-LCA）等混合和新兴方法也越来越感兴趣。基于lc的方法通常用于比较线性业务模型（BM）和CBMs的环境影响，或者指导从线性业务模型向新CBMs设计的过渡。还特别强调采用信任措施，如产品服务系统、延长产品寿命或工业共生的信任措施，而不是侧重于使用循环材料的信任措施。出现了广泛领域的全面覆盖。这项研究的意义对研究人员和管理者都很重要。对于研究人员来说，这篇综述强调了标准化工作的必要性，以改进评估信任措施的工具。对于管理人员来说，审查提供了一个8步操作框架，用于为CBM的实施进行基于lc的分析。

The European Green Deal (EGD) aims for agriculture to contribute positively to climate change mitigation and nature preservation while meeting growing societal needs for food, energy, and biomaterials. Delivering comprehensive policy action efficiently requires decision-support tools to assess the outcomes of interventions across multiple, and potentially conflicting, goals. By means of agent-based (territorial) life cycle assessment, we evaluate the effect of removing coupled cattle support and pricing greenhouse gas emissions of agricultural products in two regions in Southern Sweden as representative cases for intensive and extensive agriculture in the EU. Regional production features influenced policy outcomes by affecting the profitability of possible production activities, and thereby the economic viability of alternatives to cattle. Production changes abroad were critical for the environmental lifecycle performance of the evaluated policy reforms, given the relatively low environmental impacts of Swedish production compared to global averages. Our ex-ante approach offers decision support by discerning the implications of policy interventions on the regional structure of production and subsequent effects on the environment, considering both regional and global aspects of the EGD objectives for agriculture. Ultimately, we hope our analysis can facilitate policymaking to speed the transition of agriculture towards EGD objectives.

《欧洲绿色协议》（EGD）旨在使农业为减缓气候变化和保护自然作出积极贡献，同时满足社会对粮食、能源和生物材料日益增长的需求。有效地提供全面的政策行动需要决策支持工具，以评估跨多个且可能相互冲突的目标的干预措施的结果。通过基于主体的（领土）生命周期评估，我们评估了瑞典南部两个地区取消耦合牛支持和农产品温室气体排放定价的效果，作为欧盟集约化和粗放化农业的代表性案例。区域生产特点通过影响可能的生产活动的盈利能力，从而影响牛的替代品的经济可行性，从而影响政策结果。鉴于瑞典生产对环境的影响与全球平均水平相比相对较低，国外的生产变化对所评价的政策改革的环境生命周期绩效至关重要。我们的事前方法通过识别政策干预对区域生产结构的影响以及随后对环境的影响，同时考虑到农业EGD目标的区域和全球方面，为决策提供支持。最终，我们希望我们的分析能够促进政策制定，加快农业向EGD目标的转变。

As companies intensify efforts to decarbonize their supply chains to mitigate climate-related risks, their responses often remain fragmented and uncoordinated, limiting overall effectiveness and missing opportunities for synergy. This study analyzes disclosures from 1095 European firms reported to the Carbon Disclosure Project (CDP) to examine these varied responses. Using qualitative thematic coding, we identified six macro-themes, each representing a distinct causal-effect pathway that companies adopt in their decarbonization efforts: (i) diagnosing climate-related risks, (ii) collaborating within the supply chain to reduce emissions, (iii) adopting energy-efficient practices, (iv) implementing sustainable practices that minimize waste, (v) fostering enablers of sustainable behavior, and (vi) redesigning supply chain networks. These pathways highlight the strategies companies use to address climate risks within their supply chains. Adopting a systems dynamics perspective, we map the feedback processes governing these decarbonization strategies, illustrating how different pathways interact and generate either beneficial or detrimental outcomes. The findings contribute to the field of sustainable supply chain management by elucidating the dynamic interplay between various climate risk response strategies, their impact on supply networks, and their ultimate influence on climate risk performance. Specifically, we demonstrate the iterative nature of diagnostic efforts and associated responses, and how collaboration can drive a continuous cycle of innovation that integrates incremental and transformative efforts. The causal loop diagrams developed in this study provide managers and policymakers tools to anticipate the outcomes of their supply chain strategies, enabling better-informed decisions that align with sustainability objectives.

随着企业加大努力使供应链脱碳以减轻气候相关风险，他们的应对措施往往仍然是分散和不协调的，限制了整体有效性，错失了协同合作的机会。本研究分析了向碳披露项目（CDP）报告的1095家欧洲公司的信息披露，以检验这些不同的反应。使用定性主题编码，我们确定了六个宏观主题，每个主题代表了公司在脱碳工作中采用的不同因果关系途径：(i)诊断气候相关风险，（ii）在供应链内合作减少排放，（iii）采用节能实践，（iv）实施减少浪费的可持续实践，(v)培养可持续行为的推手，以及（vi）重新设计供应链网络。这些途径突出了公司在其供应链中应对气候风险的策略。采用系统动力学的观点，我们绘制了控制这些脱碳策略的反馈过程，说明了不同的途径如何相互作用并产生有益或有害的结果。通过阐明各种气候风险应对策略之间的动态相互作用，它们对供应网络的影响，以及它们对气候风险绩效的最终影响，这些发现有助于可持续供应链管理领域。具体来说，我们展示了诊断工作和相关响应的迭代性质，以及协作如何推动集成增量和变革工作的持续创新循环。本研究中开发的因果循环图为管理者和政策制定者提供了预测其供应链战略结果的工具，从而使更明智的决策与可持续发展目标保持一致。
