The paradigm shift in understanding Earth system limits and the definition of a safe operating space has underscored the need for absolute environmental sustainability. While the European Commission's Safe and Sustainable by Design (SSbD) framework sets a direction for sustainability-oriented innovation, it currently lacks operational guidance on implementing planetary boundaries (PBs) at the design level. This systematic literature review assesses the state of Absolute Environmental Sustainability Assessment (AESA) methods for defining PB thresholds and evaluates their applicability within SSbD contexts. The findings reveal that although progress has been made in linking Life Cycle Assessment (LCA) with PBs, current applications remain commonly at the meso-scale, and disconnected from low-TRL technologies and material/component-level decision-making. Key gaps persist in carrying capacity allocation, operationalization of underrepresented boundaries such as novel entities, and prospective modeling. To bridge these gaps, the study identifies four integration requirements: (1) embedding PBs from the earliest TRL stages, (2) aligning assessments with systemic design logic and developing performance-based allocation methods, (3) developing a composite carrying capacity indicator as an intermediate functional unit, and (4) incorporating scenario-based and temporal modeling to reflect the dynamic context of technology emergence. Together, these requirements lay the foundation for a structured, forward-oriented workflow to support actionable PB integration into SSbD.

在理解地球系统极限和安全操作空间定义方面的范式转变强调了绝对环境可持续性的必要性。虽然欧盟委员会的安全与可持续设计（SSbD）框架为以可持续为导向的创新设定了方向，但它目前缺乏在设计层面实施地球边界（PBs）的操作指导。这篇系统的文献综述评估了用于定义PB阈值的绝对环境可持续性评估（AESA）方法的现状，并评估了它们在SSbD背景下的适用性。研究结果表明，尽管在将生命周期评估（LCA）与PBs联系起来方面取得了进展，但目前的应用仍然普遍停留在中尺度，与低trl技术和材料/组件级决策脱节。关键的差距仍然存在于承载能力分配、未充分代表的边界（如新实体）的操作化和前瞻性建模。为了弥补这些差距，研究确定了四个集成需求：(1)从最早的TRL阶段嵌入PBs；(2)将评估与系统设计逻辑结合起来，开发基于性能的分配方法；(3)开发复合承载能力指标作为中间功能单元；(4)结合基于场景和时间的建模，以反映技术出现的动态背景。总之，这些需求为结构化的、面向前的工作流奠定了基础，以支持可操作的PB集成到SSbD中。

The interregional grain trade system fosters a complex water‑carbon coupled network, which exacerbates spatial disparities in both water allocation and carbon transfer. Previous studies focused on the virtual water trade's role in food security and agricultural water use but overlooked inter-industry “water–carbon” transfer mechanisms. This study pioneers two innovative metrics: Virtual water flow spillover efficiency and potential carbon neutrality benefit, thereby expanding the analytical perspective to unravel the interregional water‑carbon flow mechanisms within regions. This study constructs a spatiotemporal analytical framework for China's grain-related virtual water‑carbon flows at a regional-industrial nexus scale by integrating social equity principles with an optimized minimum cost maximum flow algorithm. And establishes a synergistic optimization methodology for “regional carbon reduction - water use efficiency enhancement”, enabling precise identification of dual optimization pathways for resource-environment systems. Results reveal that China's virtual water flow for rice, wheat, and corn increased by 18.2 %, and virtual carbon flow increased by 18.3 % totally. The northeast emerged as a major virtual water exporter, while coastal provinces shifted toward net import status, exacerbating regional water disparities. This study illuminates the substantial carbon benefits arising from intra-industrial resource restructuring triggered by regional grain trade. These benefits far surpass previous estimates derived solely from interregional carbon emission reductions, thereby challenging the conventional accounting framework for its systemic underestimation of grain trade's carbon mitigation potential. Critical pathways, notably Hebei-Tianjin and Shanxi-Guangdong, were identified as dual resource-environment optima. These pathways facilitate water‑carbon constructive collaboration within large-scale agricultural trade systems, thereby providing actionable strategies for sustainable food-water‑carbon nexus management.

区域间粮食贸易体系形成了复杂的水碳耦合网络，加剧了水分配和碳转移的空间差异。以往的研究主要关注虚拟水交易在粮食安全和农业用水中的作用，但忽视了行业间“水-碳”转移机制。本研究提出了虚拟水流溢出效率和潜在碳中和效益两个创新指标，从而拓展了分析视角，揭示了区域间水碳流动机制。本研究将社会公平原则与优化的最小成本最大流量算法相结合，构建了区域-产业联系尺度下中国粮食相关虚拟水碳流的时空分析框架。建立了“区域减碳-提高水利用效率”的协同优化方法，实现了资源环境系统双优化路径的精准识别。结果表明，中国水稻、小麦和玉米的虚拟水流量增加了18.2%，虚拟碳流量增加了18.3%。东北成为主要的虚拟水出口国，而沿海省份则转向净进口，加剧了区域水资源差距。本研究阐明了由区域粮食贸易引发的产业内资源重组所带来的巨大碳效益。这些效益远远超过以往仅从区域间碳减排中得出的估计，从而挑战了传统核算框架对粮食贸易碳减排潜力的系统性低估。关键路径以冀津和晋粤为双资源环境最优。这些途径促进了大规模农业贸易体系内的水碳建设性合作，从而为可持续的粮食-水-碳关系管理提供了可行的战略。

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. Moreover, this finding presents a strategic opportunity for food producers and marketers to align sustainability and nutrition in their messaging, fostering both health-conscious and environmentally responsible consumption behavior.

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。

Effective monitoring of the Sustainable Development Goals (SDGs) is crucial for advancing global sustainable development. However, widespread data gaps continue to hinder the accurate assessment of SDG performance across countries and goals. To address this challenge, this study develops a data-driven integrated assessment framework combining dimensionality reduction and machine learning-based imputation techniques, based on 380 SDG indicators from the World Bank database covering the period 2000–2020. Principal indicators were selected using a combination of Principal Component Analysis (PCA) and multiple regression, and missing data were imputed using the random forest (RF)-based missForest algorithm. Based on the completed dataset, the SDG index and performance of 17 individual SDGs were assessed for 215 countries and regions worldwide from 2000 to 2020. The results show that: (1) identification of 218 principal indicators covering over 90 % of the information in the initial set; (2) robust imputation of missing values with a Normalized Root Mean Squared Error (NRMSE) of approximately 0.2 and a Proportion of Falsely Classified (PFC) around 0.08; (3) a steady global improvement in SDG performance with significant regional disparities—Europe leading, Africa lagging, and Asia progressing most rapidly; and (4) uneven development across different goals, with some facing considerable challenges. This study enhances the completeness and applicability of global SDG performance assessment and provides empirical evidence to support more targeted sustainable development policymaking.

有效监测可持续发展目标对推动全球可持续发展至关重要。然而，广泛的数据差距继续阻碍对各国和各目标的可持续发展目标绩效进行准确评估。为了应对这一挑战，本研究基于世界银行数据库中2000-2020年期间的380项可持续发展目标指标，开发了一个数据驱动的综合评估框架，结合了降维和基于机器学习的imputation技术。采用主成分分析（PCA）和多元回归相结合的方法选择主指标，采用基于随机森林（RF）的misforest算法对缺失数据进行估算。根据已完成的数据集，对2000年至2020年全球215个国家和地区的可持续发展目标指数和17个单项可持续发展目标的绩效进行了评估。结果表明：(1)对218个主要指标进行了识别，覆盖初始集信息的90%以上；(2)缺失值的稳健性估计，归一化均方根误差（NRMSE）约为0.2，错误分类比例（PFC）约为0.08；(3)全球可持续发展目标绩效稳步提升，但区域差异显著——欧洲领先，非洲落后，亚洲进步最快；(4)不同目标间发展不平衡，部分目标面临较大挑战。本研究增强了全球可持续发展目标绩效评估的完整性和适用性，为更有针对性的可持续发展政策制定提供了实证依据。

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。

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。

Policy coherence is a sought-after characteristic in cross-sectoral sustainability transformations. Despite the wealth of research on policy mixes and the urgent need to advance environmental sustainability in production and consumption cycles, only a limited number of studies empirically examine policy coherence in practice within policy mixes for the circular economy. To address this gap, our paper unpacks the EU's circular economy policy mix as a system of linked policies whose policy coherence is experienced by actors in the circular economy space, specifically in the electronics and ICT, batteries, automotive and critical raw materials sectors. The circular economy is an important area for studying policy coherence because it has been subject to a significant increase in policy adoption, all while the mainstreaming of circular economy practices remains insufficient at the EU level. Combining a top-down and bottom-up approach to populate the policy mix, we use network analysis to assess the synergies and conflicts among the policies in the mix through the surveyed experiences of 36 business actors. We find that on average the EU's circular economy policy mix exhibits a medium-to-high average degree of coherence. At the same time, however, our results show that the coherence between policies is not uniform within the mix as there is a diverse degree of coherence among its policies. Looking closely into inter-policy coherence reveals several cases of medium-to-low coherence. Moreover, our results indicate that the EU's policy mix for the circular economy lacks clusters of policies, which reduces the resilience of the policy mix to external shocks. We conclude that more emphasis should be given to aligning the objectives of EU circular economy, industrial and climate policies, and to providing a coherent set of requirements for EU businesses.

政策一致性是跨部门可持续性转型所追求的特征。尽管对政策组合进行了大量研究，迫切需要提高生产和消费周期中的环境可持续性，但只有有限数量的研究从经验上考察了循环经济政策组合实践中的政策一致性。为了解决这一差距，我们的论文将欧盟的循环经济政策组合分解为一个相互关联的政策体系，其政策一致性由循环经济领域的参与者体验，特别是在电子和信息通信技术、电池、汽车和关键原材料领域。循环经济是研究政策一致性的一个重要领域，因为它受到政策采纳的显著增加的影响，而在欧盟层面，循环经济实践的主流化仍然不足。结合自上而下和自下而上的方法来填充政策组合，我们通过对36个业务参与者的调查经验，使用网络分析来评估组合中政策之间的协同作用和冲突。我们发现，平均而言，欧盟的循环经济政策组合表现出中等到高度的平均一致性。然而，与此同时，我们的结果表明，政策之间的一致性在混合中并不统一，因为其政策之间存在不同程度的一致性。仔细观察政策间的一致性，就会发现几个中低一致性的例子。此外，我们的研究结果表明，欧盟的循环经济政策组合缺乏政策集群，这降低了政策组合对外部冲击的抵御能力。我们的结论是，应该更加重视协调欧盟循环经济、工业和气候政策的目标，并为欧盟企业提供一套连贯的要求。

Sustainability of autonomous cars: Environmental, social, and economic insights from a systematic review 自动驾驶汽车的可持续性：来自系统回顾的环境、社会和经济见解

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。

Critical assessment of the scope and applicability of circularity indicators for the sustainable life cycle management of wind turbine blades 风力发电机叶片可持续生命周期管理中循环度指标的范围和适用性的关键评估

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。

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。
