The clean energy transition is increasing the demand for electric vehicle (EV) batteries. In 2022, the US passed the Inflation Reduction Act (IRA) aiming to reshore and friendshore the battery supply chain, and to de-risk from dependence on China. The IRA and any follow-on permutations thereof such as the One Big Beautiful Bill Act (OBBBA) are expected to impact the source, and consequently, the environmental footprint of battery materials and components. As new policies and regulations reshape the battery supply chain, they could lead to unintended and potentially negative sustainability impacts for new EV batteries if applied indiscriminately. The current study uses life cycle assessment to estimate the environmental footprint of NMC811 cells under different supply chain scenarios. These scenarios reflect offshoring and friendshoring the battery supply chain, reshoring battery manufacturing, and reshoring battery materials production. Further, this study explores paths to reduce the environmental footprint of 100 % US-made batteries using renewable energy sources during production. For the scenarios considered, the results show that offshoring and friendshoring the battery supply chain can lead to the highest and lowest environmental impacts, respectively. Reshoring battery manufacturing and using 1.15 Wp/kWh NMC811 cell produced can reduce the carbon footprint of a US-made 70 kWh NMC811 LIB pack by 2.45 tons CO₂-eq and the water consumption by 5584 L. The outcomes of this work inform policymakers on the complex environmental consequences of supply chain decisions and identify pathways to mitigate these environmental consequences through selective material sourcing and implementation of renewable energy sources.

清洁能源转型正在增加对电动汽车电池的需求。2022年，美国通过了《通货膨胀削减法案》（IRA），旨在将电池供应链回流和友好化，并降低对中国的依赖风险。IRA和任何后续的排列，如“一个大美丽法案”（OBBBA），预计将影响电池的来源，从而影响电池材料和组件的环境足迹。随着新的政策和法规重塑电池供应链，如果不加选择地应用，它们可能会对新型电动汽车电池的可持续性产生意想不到的潜在负面影响。本研究采用生命周期评估方法对不同供应链情景下NMC811电池的环境足迹进行评估。这些情况反映了电池供应链的离岸外包和友军外包，电池制造的回流，以及电池材料生产的回流。此外，本研究探索了在生产过程中使用可再生能源减少100%美国制造电池的环境足迹的途径。对于所考虑的情景，结果表明，电池供应链的离岸外包和友好外包分别会导致最高和最低的环境影响。回收电池制造和使用1.15 Wp/kWh的NMC811电池可以使美国制造的70 kWh NMC811 LIB电池组的碳足迹减少2.45吨二氧化碳当量，用水量减少5584 l。这项工作的结果为决策者提供了供应链决策的复杂环境后果的信息，并确定了通过选择性材料采购和实施可再生能源来减轻这些环境后果的途径。

The circular bioeconomy integrates the principles of both circular economy and bio-based economy, representing a promising pathway toward a more sustainable economic model. Current approaches to assessing circularity for bio-based product systems present notable limitations, as existing circularity assessment instruments (CAIs) often fail to adequately capture the particular properties of bio-based resource flows. To address these challenges, a comprehensive and systematic literature review was conducted to identify and evaluate CAIs applicable to the assessment of circularity in bio-based products. A total of 86 circularity indicators, indicator sets, and tools were examined based on their methodological scope and depth, including how they address resource flows, system boundaries, and material properties. Additional attention was given to their coverage of sustainability aspects, as well as their practical applicability. The analysis revealed several key gaps: a predominant emphasis on academic applications with limited industrial implementation; insufficient consideration of resource renewability and return to the biosphere; and an unclear distinction between circularity and sustainability aspects. Building on these findings, two contributions are proposed to advance circularity assessment methodologies: (i) a systems diagram conceptualising the circular bioeconomy, and (ii) a list of seven theoretical key elements essential for comprehensive circularity assessment. By synthesising these findings and advocating for the harmonisation of CAIs, this study provides guidance for developing indicators that better capture the different dimensions of the circular bioeconomy, offering a basis for policymaking and industry to deepen their understanding of circularity performance in the bio-based economy.

循环生物经济融合了循环经济和生物基经济的原则，代表了一条通往更可持续经济模式的有希望的道路。目前评估生物基产品系统循环性的方法存在明显的局限性，因为现有的循环性评估工具（CAIs）往往不能充分捕捉生物基资源流动的特定特性。为了应对这些挑战，进行了全面和系统的文献综述，以确定和评估适用于生物基产品循环性评估的CAIs。共有86个循环指标、指标集和工具根据它们的方法范围和深度进行了检查，包括它们如何处理资源流动、系统边界和材料属性。另外还注意到它们所涵盖的可持续性方面以及它们的实际适用性。分析揭示了几个关键的差距：主要强调学术应用，工业实施有限；对资源可再生性和对生物圈的回归考虑不足；循环性和可持续性之间的区别也不明确。在这些发现的基础上，提出了两项贡献来推进循环性评估方法：(i)将循环生物经济概念化的系统图，以及（ii）综合循环性评估所必需的七个理论关键要素的列表。通过综合这些发现并倡导cai的统一，本研究为制定更好地捕捉循环生物经济不同维度的指标提供了指导，为政策制定和行业加深对生物经济循环绩效的理解提供了基础。

Planetary boundaries delimit the safe operating space for humanity to ensure the stability and functioning of the Earth system. Demand-side indicators can help navigate specific pathways and solutions to stay within the boundaries. In recent years, an increasing quantity of scientific work is connecting planetary boundary framing to demand-side analysis, yet there is often a lack of consistency in this research. Here we review relevant literature (including life-cycle assessments and environmental footprint analysis), focusing on the choice and suitability of indicators and methods used. We find a persistent gap between the idealist focus on impacts on earth systems functioning and the actual indicators used. We evaluate the available options, outline current research gaps, and extract lessons on how to better account for Earth system impacts from the demand-side perspective.

行星边界划定了人类的安全活动空间，以确保地球系统的稳定和运作。需求侧指标可以帮助引导特定的路径和解决方案，以保持在边界内。近年来，越来越多的科学工作将行星边界框架与需求侧分析联系起来，但这种研究往往缺乏一致性。在此，我们回顾了相关文献（包括生命周期评估和环境足迹分析），重点关注所使用的指标和方法的选择和适用性。我们发现，理想主义者关注对地球系统功能的影响与所使用的实际指标之间存在持续的差距。我们评估了可用的选择，概述了当前的研究差距，并从需求方的角度提取了如何更好地解释地球系统影响的经验教训。

Climate change is expected to decrease crop yields and increase irrigation demands, compounded by worsening hydrological changes. Because these impacts vary across regions, spatially resolved environmental impact assessments are needed to enable proactive and targeted management strategies. To address this need, this study assesses the spatial variations in the environmental sustainability of wheat production in Pakistan by combining Geographic Information Systems with Life Cycle Assessment. Under Representative Concentration Pathway 8.5, for 2030–39, which projects a potential decline in crop yields, increased irrigation demand, and reduced water table levels. The findings project global warming is expected to rise by 4–12 % relative to the baseline. Other impact categories—including particulate matter formation, acidification, freshwater and marine eutrophication, and land use—are projected to increase within a range of 4–11 %. Fossil resource use is anticipated to increase by 4–13 %, while water consumption is projected to rise by 7–17 % during the same period. For most mid- and end-point impact categories, the northern and southern regions generally fall within the upper range, whereas the central region represents the lower range within the study area. These findings underscore the importance of context-specific adaptation by integrating spatially detailed data into Geographic Information Systems and Life Cycle Assessment tools, thereby enabling targeted interventions that optimize resources, mitigate vulnerabilities, and minimize environmental impacts. Key adaptive strategies include using solar-powered tube wells, partially replacing synthetic fertilizers with organic alternatives, improving irrigation efficiency, and enhancing soil fertility to sustain crop farming in arid and semi-arid regions.

气候变化预计会降低作物产量，增加灌溉需求，再加上水文变化的恶化。由于这些影响因区域而异，因此需要进行空间解决的环境影响评估，以实现主动和有针对性的管理战略。为了满足这一需求，本研究将地理信息系统与生命周期评估相结合，评估了巴基斯坦小麦生产环境可持续性的空间变化。在代表性浓度路径8.5下，2030-39年，预计作物产量可能下降，灌溉需求增加，地下水位下降。研究结果显示，全球变暖预计将比基线上升4 - 12%。其他影响类别——包括颗粒物质形成、酸化、淡水和海洋富营养化以及土地利用——预计将增加4 - 11%。化石资源的使用预计将增加4 - 13%，而同期的用水量预计将增加7 - 17%。对于大多数中期和终点影响类别，北部和南部地区通常处于较高范围内，而中部地区则代表研究区域内的较低范围。这些发现强调了通过将空间详细数据整合到地理信息系统和生命周期评估工具中来适应特定环境的重要性，从而实现有针对性的干预措施，优化资源，减轻脆弱性，最大限度地减少环境影响。关键的适应性策略包括使用太阳能管井，用有机替代品部分替代合成肥料，提高灌溉效率，提高土壤肥力，以维持干旱和半干旱地区的作物种植。

A prospective life cycle assessment approach is employed to analyse the environmental impacts of green e‑hydrogen production from an alkaline electrolyser powered by an off-grid solar photovoltaics-wind power system coupled with underground hydrogen storage. The future environmental impacts of hydrogen production are examined using scenarios based on power sector defossilisation scenarios of the LUT Energy System Transition Model, employing the premise tool and Activity Browser. Finland, Germany, Spain, and Chile are selected as case studies due to their varying regional climate zones and different shares of solar photovoltaics and wind power. Results reveal GWP₁₀₀ values per kWh_H2,LHV decrease from 30.7 to 47.2 g CO_2-eq to 12.0 - 16.5 g CO_2-eq from 2020 to 2050. Chile, with a very high solar photovoltaics share in the off-grid system, has lower environmental impacts compared to other countries with higher wind power shares such as Finland and Germany. By 2050, the remaining greenhouse gas emissions arise from the production of materials mainly steel, silicon, concrete, and aluminium, and from fossil fuel use in road and maritime transportation and indicate need for improvement in methodology and data. Other environmental indicators exhibit improvements of 20–53% in human health, ecosystem quality, and resource use, while minor increases in acidification and human toxicity are attributable to material production and system operation. Transitioning to 100% renewable energy for materials and transportation could effectively bring these residual emissions to near zero and further enhance environmental impacts.

采用前瞻性生命周期评估方法分析了由离网太阳能光伏-风力发电系统和地下储氢系统驱动的碱性电解槽生产绿色氢的环境影响。基于LUT能源系统转型模型的电力部门化石化情景，采用前提工具和活动浏览器，研究了氢气生产对未来环境的影响。芬兰、德国、西班牙和智利之所以被选为案例研究，是因为这些国家的区域气候带不同，太阳能光伏和风能的份额也不同。结果表明，从2020年到2050年，每kWhH2、LHV的GWP100值从30.7 ~ 47.2 g CO2-eq下降到12.0 ~ 16.5 g CO2-eq。智利在离网系统中太阳能光伏发电的份额非常高，与芬兰和德国等风电份额较高的国家相比，智利的环境影响较小。到2050年，剩余的温室气体排放主要来自钢铁、硅、混凝土和铝等材料的生产，以及公路和海上运输中化石燃料的使用，这表明需要改进方法和数据。其他环境指标在人类健康、生态系统质量和资源利用方面改善了20-53%，而酸化和人体毒性的轻微增加可归因于物质生产和系统运行。向100%可再生能源的材料和运输过渡可以有效地将这些残余排放降至接近零，并进一步增强对环境的影响。

Reducing meat consumption is crucial for addressing environmental and health challenges; however, implementing effective policies requires public support. This study investigates psychological and political determinants of public acceptance of four proposed meat reduction policies in Finland—two price-based and two availability-based measures—developed from expert recommendations. Using a representative sample of Finnish adults (N = 1999), we applied structural equation modeling to examine how perceived policy fairness, effectiveness, and intrusiveness mediate the influence of environmental risk perception and political trust on policy acceptance. Acceptance rates ranged from 25 % for the prohibition of discount sales to 35 % for taxing the most environmentally harmful meat products. Of the proximal predictors, perceived fairness had the strongest association with acceptance across all policies. Perceived effectiveness and intrusiveness had smaller associations. Environmental risk perception showed a large indirect effect on acceptance. Political trust had a moderate indirect effect on acceptance, primarily through perceived fairness. These findings suggest that future communication strategies might benefit most from emphasizing policy fairness. Interventions targeting distal predictors may aim to raise environmental risk awareness, although this strategy must be pursued carefully to avoid fear-based disengagement. This cross-sectional work opens exciting avenues for future research using experimental or longitudinal designs.

减少肉类消费对于应对环境和健康挑战至关重要；然而，实施有效的政策需要公众的支持。本研究调查了公众接受芬兰四项拟议的肉类减少政策的心理和政治决定因素——两项基于价格的措施和两项基于可获得性的措施——根据专家建议制定。采用芬兰成年人代表性样本（N = 1999），我们采用结构方程模型来检验感知政策公平性、有效性和侵入性如何中介环境风险感知和政治信任对政策接受的影响。接受率从禁止打折销售的25%到对最有害环境的肉制品征税的35%不等。在最接近的预测因素中，感知到的公平与所有政策的接受程度有最强烈的联系。感知有效性和侵入性的关联较小。环境风险感知对接受度有较大的间接影响。政治信任对接受度有适度的间接影响，主要是通过感知公平。这些发现表明，未来的沟通策略可能从强调政策公平性中获益最多。针对远端预测因子的干预措施可能旨在提高环境风险意识，尽管这一策略必须谨慎执行，以避免基于恐惧的脱离接触。这项横断面研究为未来使用实验或纵向设计的研究开辟了令人兴奋的途径。

The European Green Deal was presented in late 2019 as a leading action plan to transform Europe's economy with ambitious targets to cut greenhouse gas emissions by 55 % by 2030 and for the EU to become climate neutral by 2050. Through a systematic literature review of 77 research articles published from 2020 to 2024, main enablers and barriers to achieve European Green Deal objectives are identified and categorized. A conceptual framework is proposed integrating nine categories of enablers and barriers to implementation with the eight objectives of the European Green Deal, according to their distinct relevance in the literature: (1) Public policy, governance and regulatory; (2) Economic; (3) Cultural; (4) Market; (5) Technology and infrastructure (6) Supply chain management; (7) Stakeholder engagement; (8) Business strategy and company culture; and (9) Business competences. The results also show that the literature overlooks aspects like the social dimension of the European Green Deal or coordination of supply chain related practices like reverse logistics. Accordingly, we suggest policymakers to: (1) Redesign policy initiatives considering these nine categories of factors and their interactions to more systematically seize the opportunities and address the obstacles to implementation; (2) Providing financial incentives for circular products and clean energy technologies (3) Adopting a holistic approach to sustainable strategies including economic, technological and organizational factors (4) Integrating social protection policies to EGD framework to reduce poverty and emissions.

《欧洲绿色协议》于2019年底提出，是一项引领欧洲经济转型的行动计划，其雄心勃勃的目标是到2030年将温室气体排放量减少55%，到2050年欧盟实现气候中和。通过对2020年至2024年发表的77篇研究论文的系统文献综述，确定并分类了实现欧洲绿色协议目标的主要推动因素和障碍。根据其在文献中的独特相关性，提出了一个概念性框架，将九类促进因素和实施障碍与欧洲绿色协议的八项目标相结合：(1)公共政策、治理和监管；(2)经济;(3)文化;(4)市场;(5)技术与基础设施(6)供应链管理；(7)利益相关者参与；（八）经营战略和企业文化；(9)业务能力。研究结果还表明，文献忽略了欧洲绿色协议的社会维度或逆向物流等供应链相关实践的协调等方面。因此，我们建议政策制定者：(1)考虑这九类因素及其相互作用，重新设计政策举措，以更系统地抓住机遇，解决实施障碍；(2)为循环产品和清洁能源技术提供财政激励；(3)采用综合经济、技术和组织因素的可持续战略；(4)将社会保护政策纳入环境发展框架，以减少贫困和排放。

Parametric Life Cycle Assessment (Pa-LCA) is a dynamic modeling and analysis approach that integrates predefined variable parameters to enable the assessment of environmental impacts. This methodology enhances the flexibility of life cycle sustainability assessments, particularly in processes characterized by uncertainty or variability. Given this, the effective selection of parameters is required, in order to develop a meaningful Pa-LCA, which can be adapted accordingly to the objectives identified for the analysis. While Pa-LCA is widely used in the literature, there is still a need to define an assessment path for its effective application, since, unlike conventional LCA, Pa-LCA is not a standardized method. Given this, a comprehensive review of existing Pa-LCA studies has been conducted. This review focuses on how parameters are identified, selected and operationalized, how functional units are adapted to parametric contexts, and if key performance indicators (KPIs) are considered on the definition. Through this analysis, methodological gaps and inconsistencies were identified that hinder the broader adoption and effectiveness of Pa-LCA. To address these challenges, a structured methodological roadmap has been developed, aiming at guiding researchers and practitioners in the development of robust and effective Pa-LCA models. This roadmap encompasses the definition of the parametric model considered, the selection of the most influential parameters, the use of parametric data for the development of a conventional LCA, the design of sensitivity and uncertainty analyses, and the interpretation of results for decision-making. By bridging theoretical and practical implementation strategies, and by the identification of actual gaps and challenges, this guide aims to standardize Pa-LCA practices and promote its use for developing dynamic life cycle assessments. It is hoped that the outcomes of this article could contribute to advancing the methodological maturity of Pa-LCA and unlocking its potential for more adaptive and informed sustainability assessments.

参数生命周期评估（Pa-LCA）是一种动态建模和分析方法，它集成了预定义的可变参数，以实现对环境影响的评估。这种方法提高了生命周期可持续性评估的灵活性，特别是在以不确定或可变性为特征的过程中。鉴于此，需要有效地选择参数，以便制定有意义的Pa-LCA，可以根据为分析确定的目标进行相应的调整。虽然Pa-LCA在文献中得到了广泛的应用，但由于与传统的LCA不同，Pa-LCA不是一种标准化的方法，因此仍然需要定义有效应用的评估路径。鉴于此，对现有的Pa-LCA研究进行了全面审查。这篇综述的重点是如何识别、选择和操作参数，如何使功能单元适应参数环境，以及在定义中是否考虑了关键绩效指标（kpi）。通过这一分析，发现了方法学上的差距和不一致，这些差距和不一致阻碍了Pa-LCA的广泛采用和有效性。为了应对这些挑战，我们制定了一个结构化的方法路线图，旨在指导研究人员和实践者开发稳健有效的Pa-LCA模型。该路线图包括所考虑的参数模型的定义、最具影响力的参数的选择、用于开发传统LCA的参数数据的使用、灵敏度和不确定性分析的设计以及对决策结果的解释。通过衔接理论和实践实施战略，并通过确定实际差距和挑战，本指南旨在使Pa-LCA实践标准化，并促进其用于开发动态生命周期评估。希望本文的研究成果能够促进Pa-LCA方法的成熟，并释放其在更具适应性和更明智的可持续性评估方面的潜力。

The increasing consumption of animal-based proteins causes substantial environmental impacts, necessitating a shift towards alternative proteins. Seaweed-based proteins offer a promising solution, with several studies suggesting low environmental impacts and valuable nutritional properties. This paper conducts a literature review on seaweed-based proteins, aiming to summarize the current knowledge on their environmental impacts while deriving recommendations for future LCA studies. Following a two-tier approach, a broad literature sample of 139 studies was identified to summarize relevant value chains, while fourteen key LCA studies were analyzed in more detail, also considering methodological choices and impact assessment results. The study proposes a harmonized value chain framework that facilitates comparison across studies, revealing heterogeneity in the investigated value chains regarding cultivation, processing technologies, and seaweed types. Gaps exist for green and red seaweed, novel extraction technologies and downstream steps, such as product formulation and use phase. Some methodological shortcomings are evident, particularly in addressing multifunctionality, marine biodiversity impacts and product functionality. Across all studies, transparency in methodological choices and the system description could be improved. The synthesis of impact assessment results suggests that seaweed-based proteins exhibit lower environmental impacts than animal-based proteins: when assessed considering protein content, climate impact can be reduced by between 30 % and 100 % compared to poultry. Based on these insights, the review names underrepresented value chains to be prioritized in future studies. Guidance is given on selecting system boundaries, functional units, and multifunctionality approaches in line with study objectives as well as options for incorporating marine biodiversity into LCA.

动物性蛋白质消费量的增加对环境造成了重大影响，需要转向替代蛋白质。基于海藻的蛋白质提供了一个很有前途的解决方案，一些研究表明对环境的影响小，营养价值高。本文对基于海藻的蛋白质进行了文献综述，旨在总结目前对其环境影响的认识，并对未来的LCA研究提出建议。遵循两层方法，确定了139项研究的广泛文献样本来总结相关价值链，同时更详细地分析了14项关键的LCA研究，同时考虑了方法选择和影响评估结果。该研究提出了一个统一的价值链框架，促进了研究之间的比较，揭示了所调查价值链在种植、加工技术和海藻类型方面的异质性。在绿海藻和红海藻、新型提取技术和下游步骤（如产品配方和使用阶段）方面存在差距。一些方法上的缺陷是明显的，特别是在处理多功能性、海洋生物多样性影响和产品功能方面。在所有研究中，可以提高方法选择和系统描述的透明度。综合影响评估结果表明，基于海藻的蛋白质比基于动物的蛋白质表现出更低的环境影响：当考虑蛋白质含量进行评估时，与家禽相比，气候影响可减少30%至100%。基于这些见解，该综述列出了在未来研究中优先考虑的未被充分代表的价值链。指导如何根据研究目标选择系统边界、功能单元和多功能方法，以及如何将海洋生物多样性纳入LCA。

Rebound effects (RE), in which induced behavioural or systemic responses offset sustainability gains, represent a critical challenge for design for sustainability. While mitigation has traditionally dominated the discourse, this study advances an ex-ante, preventive approach by identifying and systematising behavioural design strategies with the potential to prevent RE. Using a systematic literature review, 58 unique behavioural design strategies were identified and classified across three criteria: design levels (e.g., product and socio-technical systems, to clarify the scope at which interventions can be operationalised), rebound triggers (e.g., reappraisal of consequences, cognitive biases, to establish a clear link with related rebound mechanisms), and leverage points for systemic change (e.g., information flows, system goals and paradigms, to explore their potential in system change, from shallower adjustments to deeper structural changes). Strategies were further clustered into 13 prevention dimensions, ranging from reflective feedback to co-design. The analysis reveals that the majority of identified strategies operate at the PSS and STS levels, with a strong concentration around mid-level leverage points, particularly the structure of information flows, and behavioural triggers such as cognitive biases and moral licensing. These findings highlight the potential of design to shape behaviour and contribute to the prevention of RE and propose a framework to support the selection of design strategies. Finally, future research is recommended to enhance the generalisability of the identified strategies through empirical testing, as well as to expand into behavioural change techniques, to develop a practical design catalogue for rebound prevention.

反弹效应（RE），即诱导的行为或系统反应抵消了可持续性收益，是可持续性设计的一个关键挑战。虽然缓解传统上占主导地位，但本研究通过识别和系统化具有预防可再生能源潜力的行为设计策略，提出了一种事前预防方法。通过系统的文献综述，确定了58种独特的行为设计策略，并根据三个标准进行了分类：设计层面（例如，产品和社会技术系统，以澄清干预措施可以运作的范围），反弹触发器（例如，对后果的重新评估，认知偏差，以建立与相关反弹机制的明确联系），以及系统变化的杠杆点（例如，信息流，系统目标和范式，以探索其在系统变化中的潜力，从较浅的调整到更深的结构变化）。从反思性反馈到协同设计，这些策略被进一步分为13个预防维度。分析显示，大多数已确定的策略在PSS和STS水平上运作，高度集中在中级杠杆点周围，特别是信息流结构，以及认知偏见和道德许可等行为触发点。这些发现强调了设计在塑造行为和预防可再生能源方面的潜力，并提出了一个框架来支持设计策略的选择。最后，建议未来的研究通过实证测试来增强所确定策略的普遍性，并扩展到行为改变技术，以制定预防反弹的实用设计目录。
