Nano-detergents formulated by incorporating nanomaterials into conventional detergent have drawn great attention due to the superior cleaning performance and favorable physicochemical properties. However, further analyses of potential risks and environmental impacts are necessary. Grounded in the principles of Safe and Sustainable by Design (SSbD), this study combined life cycle assessment (LCA) with scenario analysis to evaluate environmental impacts of two Fe₃O₄-based nano-detergents (Fe₃O₄-NDGs) acorssed four stages: raw materials and energy, production, use and discharge. Then, four scenarios were established to explore potential mitigation pathways: use efficiency (S1), energy structure (S2), formulation optimization (S3) and nano-detergent recycling (S4). Baseline results showed that marine aquatic ecotoxicity potential (MAEP), freshwater ecotoxicity potential (FETP), abiotic depletion of fossil fuels (ADFP), and global warming potential (GWP) were the dominant environmental impact indicators. The two Fe₃O₄-NDGs environmental impacts were primarily concentrated in production stage. For NDG-1, the production stage respectively contributed 97.50 %, 93.69 %, and 75.37 % to FETP, PHO, and HTTP. GWP was 0.726 kg CO₂ eq. For NDG-2, this stage respectively contributed to FETP, PHO, and HTP reached 97.76 %, 94.32 %, and 75.97 %. GWP was 0.628 kg CO₂ eq. The key influencing factors during production were the use of chemical materials and electricity. Scenario analysis revealed that NDG-2 was more sensitive to S1, with environmental impact indicators decreasing by 22.06 %. S2 performed mitigation for two Fe₃O₄-NDGs. S3 reducted FETP and PHO of NDG-1 by more than 40 %. Based on the results, to minize enviromental impacts, it was recommended that future research and development should prioritize the use of green alternatives of raw materials during the production. Cleaner energy could mitigate the environmental impacts of nano-detergents effectively. This study provides the scientific evidence for sustainable development of environmental friendly cleaning products.

将纳米材料掺入常规洗涤剂中制备的纳米洗涤剂因其优异的清洁性能和良好的理化性能而备受关注。然而，有必要进一步分析潜在的风险和环境影响。本研究以安全与可持续设计（SSbD）原则为基础，将生命周期评价（LCA）与情景分析相结合，从原料与能源、生产、使用和排放四个阶段对两种fe3o4纳米去污剂（Fe3O4-NDGs）进行了环境影响评价。在此基础上，建立了利用效率（S1）、能量结构（S2）、配方优化（S3）和纳米洗涤剂回收（S4）四种情景，探讨了潜在的减排途径。基线结果表明，海洋水生生态毒性潜力（MAEP）、淡水生态毒性潜力（FETP）、化石燃料的非生物耗竭（ADFP）和全球变暖潜力（GWP）是主要的环境影响指标。两种Fe3O4-NDGs环境影响主要集中在生产阶段。NDG-1在生产阶段对FETP、PHO和HTTP的贡献率分别为97.50%、93.69%和75.37%。GWP为0.726 kg CO2当量。对于NDG-2，该阶段对FETP、PHO和HTP的贡献分别达到97.76%、94.32%和75.97%。GWP为0.628 kg CO2当量。生产过程中主要影响因素是化工原料的使用和用电。情景分析显示，NDG-2对S1更为敏感，环境影响指标下降22.06%。S2对两种Fe3O4-NDGs进行了缓释。S3可使NDG-1的FETP和PHO降低40%以上。根据研究结果，为了最大限度地减少对环境的影响，建议未来的研究和开发应优先考虑在生产过程中使用绿色替代原料。清洁能源可以有效减轻纳米洗涤剂对环境的影响。本研究为环保清洁产品的可持续发展提供了科学依据。

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。

China's household sector, comprising billions of heterogeneous energy consumers, represents an overlooked yet crucial frontier in the nation's decarbonization efforts. However, establishing effective low carbon-transition strategies for the household sector face tripartite challenges: provincial resource disparities invalidating one-size-fits-all transition strategy, pronounced urban-rural dualistic development characteristics risking energy poverty escalation, and health-threatening pollutant emissions from household energy consumption necessitating synergistic carbon-pollution mitigation. Here, we develop a high-resolution, multi-objective optimization model to identify locally-adapted pathways that synergistically address carbon emission reduction and air quality improvement across all Chinese provinces. Our analysis reveals three critical insights: First, Urban-rural disparities in household energy consumption are more pronounced than inter-provincial inequalities. Urban coal consumption inequality is decreasing due to policy interventions, while rural coal and natural gas consumption disparities are intensified. Second, nationwide household energy consumption will rise 5–10 % by 2030 (cumulative cost: $4.0–4.8 trillion), with transition pace varying dramatically. Hebei and Gansu will demonstrate rapid structural shifts toward clean energy, while Heilongjiang and Sichuan lag, necessitating targeted subsidies and infrastructure upgrades. Third, coal phase-outs will enable substantial emission reductions in SO₂ (19.7 % ~ 43.1 %) and PM (14.2 % ~ 35.5 %) by 2030, though carbon emissions may see a slight net increase due to growing household energy demand. These tailored low carbon-transition strategies enable differentiated governance and ensure energy equity by accounting for critical provincial and urban-rural disparities in household energy consumption, thereby paving a fair and efficient pathway to China's carbon neutrality goal.

中国的家庭部门由数十亿不同类型的能源消费者组成，是中国脱碳努力中一个被忽视但至关重要的前沿领域。然而，为家庭部门制定有效的低碳转型战略面临着三重挑战：省级资源差异使一刀切的转型战略无效；明显的城乡二元发展特征有可能加剧能源贫困；家庭能源消费产生的威胁健康的污染物排放需要协同减排。在这里，我们开发了一个高分辨率、多目标优化模型，以确定在中国所有省份协同解决碳减排和空气质量改善的地方适应路径。我们的分析揭示了三个关键的见解：第一，家庭能源消费的城乡差异比省际差异更明显。由于政策干预，城市煤炭消费差距正在缩小，而农村煤炭和天然气消费差距正在加剧。第二，到2030年，全国家庭能源消费将增长5 - 10%（累计成本：4.0-4.8万亿美元），转型速度差异很大。河北和甘肃将快速向清洁能源转型，而黑龙江和四川则滞后，需要有针对性的补贴和基础设施升级。第三，到2030年，逐步淘汰煤炭将使二氧化硫（19.7% ~ 43.1%）和颗粒物（14.2% ~ 35.5%）的排放量大幅减少，尽管由于家庭能源需求的增长，碳排放量可能会出现小幅净增加。这些量身定制的低碳转型战略通过考虑家庭能源消费的关键省份和城乡差异，实现差异化治理，确保能源公平，从而为实现中国的碳中和目标铺平了公平有效的道路。

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 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。

Emissions from logistics and last-mile delivery represent a growing share of global greenhouse gases, fueled by e-commerce expansion and rising demand for rapid delivery. While decarbonization is essential, existing efforts largely prioritize technological and operational solutions, leaving their broader socio-environmental implications underexplored. This study conducts a systematic literature review to define what decarbonizing last-mile logistics entails and to identify the practices most frequently proposed to reduce emissions. Building on life cycle thinking as an integrative analytical lens, the analysis reveals how these practices, while reducing carbon emissions, may also generate unintended socio-ecological effects through shifting burdens across supply chain stages.

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。

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。

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。

Integrating sustainability into product design, especially in the early stages, is a critical challenge. Manufacturers must translate broad, strategic sustainability objectives into actionable design requirements and effectively prioritize them from a life-cycle perspective to develop high-impact sustainability strategies. This study addresses this challenge by proposing a novel method framework for the elicitation, evaluation, and analysis of sustainability requirements (SRs). The framework begins with a multi-level sustainability requirement model that translates abstract strategic-level sustainability objectives into specific, actionable SRs, thereby integrating sustainability into the early design process. To further enhance decision-making, the framework incorporates Dempster-Shafer Theory (Evidence Theory) to quantify consensus among expert evaluations, resolve conflicts, and ensure decisions are both accurate and widely accepted. Next, the method integrates Decision-Making Trial and Evaluation Laboratory (DEMATEL) to identify SR interrelationships, Analytical Network Process (ANP) to prioritize them, and Total Adversarial Interpretive Structure Model (TAISM) to develop robust sustainability strategies. Rather than focusing solely on SR weight, the method emphasizes the prioritization of SR combinations that yield higher potential based on their mutual impacts. A case study on sustainable machine tools demonstrates the framework's effectiveness, with SRs comprehensively elicited, expert consensus improving from 0.7985 to 0.9260, and sustainability strategy performance improving by up to 37.6 %. An exploratory effort to integrate generative AI into sustainability requirement evaluation is also undertaken, aiming to significantly enhance decision-making efficiency. This work contributes to sustainable production and consumption by providing a systematic, stakeholder-aligned approach to generating sustainability strategies that prioritize the most impactful sustainability requirement combinations, thus driving more effective, long-term sustainable product design.

将可持续性整合到产品设计中，尤其是在早期阶段，是一个关键的挑战。制造商必须将广泛的战略性可持续发展目标转化为可操作的设计要求，并从生命周期的角度有效地优先考虑这些目标，以制定高影响力的可持续发展战略。本研究通过提出一种新的方法框架来提出、评估和分析可持续性要求（SRs），从而解决了这一挑战。该框架从一个多层次的可持续性需求模型开始，将抽象的战略层面的可持续性目标转化为具体的、可操作的可持续发展目标，从而将可持续性整合到早期设计过程中。为了进一步加强决策，该框架结合了邓普斯特-谢弗理论（证据理论）来量化专家评估之间的共识，解决冲突，确保决策既准确又被广泛接受。接下来，该方法整合了决策试验和评估实验室（DEMATEL）来识别SR相互关系，分析网络过程（ANP）来确定它们的优先级，以及总对抗解释结构模型（TAISM）来制定稳健的可持续性战略。该方法不是仅仅关注SR权重，而是强调基于相互影响产生更高潜力的SR组合的优先级。一个可持续机床的案例研究表明了该框架的有效性，可持续发展战略的可持续发展战略的绩效提高了37.6%，专家共识从0.7985提高到0.9260。还进行了将生成式人工智能集成到可持续性需求评估中的探索性工作，旨在显着提高决策效率。这项工作通过提供系统的、利益相关者一致的方法来制定可持续发展战略，优先考虑最具影响力的可持续发展要求组合，从而推动更有效、长期可持续的产品设计，从而有助于可持续生产和消费。
