Circular economy (CE) offers a pathway to achieve long-term sustainability through material reuse, recycling, and reduction (3R). This work develops a dynamic optimization framework to identify optimal time-dependent strategies for implementing these three levers of CE to achieve global sustainability. An integrated planetary model is refined to capture the 3Rs. The model is a network of interconnected compartments representing agricultural producers, the industrial sector, human consumers, and natural resource pools resembling a complex food web. A Fisher Information (FI) based optimization framework is employed with minimization of the FI variance as the objective function to ensure system stability. The circulation fraction (

CF)

and the fraction of the population reusing goods

(f)

are the dynamic decision variables. Simulations are conducted over a 200-year horizon with a one-week timestep. Results show that the business-as-usual scenario leads to system collapse at 111 years, driven by agricultural and industrial resources exhaustion. Static optimization (time-independent policy) achieves full-horizon sustainability with optimal values of

CF

= 0.3–0.45 and

f

= 0.15–0.25, depending on reuse duration. Dynamic optimization (time-varying policy) maintains sustainability with 20–40% lower average intervention levels compared to static strategies. The findings also reveal an inverse relationship between the reuse time and circulation fraction, as well as the fraction of the population reusing. The most stable outcomes occur at a reuse time of five time-steps, where dynamic control yields minimal variability and sustained ecological equilibrium. These findings provide quantitative targets for achieving SDG 12.

循环经济（CE）提供了一条通过材料再利用、再循环和减量化（3R）实现长期可持续发展的途径。这项工作开发了一个动态优化框架，以确定实施这三个可持续发展杠杆的最佳时间依赖策略，以实现全球可持续性。一个完整的行星模型被改进以捕捉3r。该模型是一个相互连接的分区网络，代表农业生产者、工业部门、人类消费者和自然资源池，类似于一个复杂的食物网。采用基于Fisher Information （FI）的优化框架，以FI方差的最小化为目标函数，保证系统的稳定性。循环率（CF）和重复使用物品的人口比例(f)是动态决策变量。模拟是在200年的范围内进行的，时间步长为一周。结果表明，在农业和工业资源枯竭的驱动下，“一切照旧”情景导致系统在111年崩溃。静态优化（时间无关策略）实现全水平可持续性，最优值CF= 0.3-0.45, f= 0.15-0.25，取决于重用持续时间。动态优化（时变策略）保持可持续性，与静态策略相比，平均干预水平低20-40%。研究结果还揭示了重复使用时间与循环比例之间的反比关系，以及重复使用人口的比例。最稳定的结果发生在五个时间步骤的重复使用时间，其中动态控制产生最小的可变性和持续的生态平衡。这些调查结果为实现可持续发展目标12提供了定量指标。

Environmental claims are widely used to influence consumers' purchase decisions; however, less is known about how consumers remember and interpret these claims, especially when presented in different formats. This study examines the effects of various eco-label formats and textual cues on consumers' spontaneous recall, interpretation, and purchase intentions. A mixed-method online experiment was conducted with a representative sample of 2000 Hungarian consumers across three product categories (food and beverages, apparel, and fabric care) and three environmental claims (recyclable, from sustainable production, and carbon neutral). Participants were exposed to five presentation formats that combined logos and either short or long texts. The results show that short textual cues, especially when combined with logos, significantly enhance spontaneous recall, while longer explanations improve their interpretation, particularly for less familiar claims. However, the interpretation did not influence purchase intention, which was instead affected by correct or incorrect spontaneous recall, perceived credibility, and environmental friendliness. Consumers responded positively to most formats of the sustainable production claim, while compared to the logo only format, other formats of the carbon neutral claim did not increase purchase intention. The recyclable claim was better interpreted than the other claims, but its effect on purchase intention varied across product categories. Overall, findings highlight the complexity of eco-label communication and suggest that tailored presentation formats are necessary to enhance consumer engagement. The study provides practical insights for policymakers and marketers aiming to foster sustainable consumer behavior through more transparent and effective environmental messaging.

环境声明被广泛用于影响消费者的购买决策；然而，消费者是如何记住和理解这些声明的，尤其是当这些声明以不同的形式呈现时，我们所知甚少。本研究考察了不同生态标签格式和文本提示对消费者自发回忆、解释和购买意愿的影响。对2000名匈牙利消费者的代表性样本进行了一项混合方法在线实验，涉及三种产品类别（食品和饮料、服装和织物护理）和三种环境声明（可回收、可持续生产和碳中和）。参与者被暴露在五种演示格式中，这些格式结合了徽标和短文本或长文本。结果表明，简短的文本提示，特别是当与商标结合在一起时，显著增强了自发的回忆，而较长的解释可以提高他们的解释，特别是对于不太熟悉的说法。然而，解释并不影响购买意愿，而是受到正确或错误的自发回忆、感知可信度和环境友好性的影响。消费者对大多数形式的可持续生产声明的反应是积极的，而与只有标志的形式相比，其他形式的碳中和声明并没有增加购买意愿。可回收的说法比其他说法更好地解释，但其对购买意愿的影响因产品类别而异。总体而言，研究结果强调了生态标签传播的复杂性，并建议定制的演示格式对于提高消费者参与度是必要的。该研究为决策者和营销人员提供了实用的见解，旨在通过更透明和有效的环境信息来促进可持续的消费者行为。

Deployment of conventional carbon capture and storage (CCS) for China's coal-fired power plants (CFPPs) is hampered by high costs and a geographical mismatch between CO₂ sources and geological sequestration sites. This study evaluates a hybrid strategy that integrates CCS with on-site microalgae utilization, presenting a novel solution that simultaneously addresses carbon mitigation and enhances domestic commodity production. The process converts captured CO₂ into high-value biomass, creating a direct substitute for carbon-intensive agricultural imports and bolstering national feed security. A spatially explicit techno-economic model was developed to assess this dual-benefit strategy for 508 CFPPs under 50% and 85% national mitigation targets. The results demonstrate compelling economic advantages. At the 85% mitigation level, the hybrid approach reduces total annualized costs by $4.9 billion (5.3%), an advantage driven by revenues from the biomass value chain and the avoidance of long-distance CO₂ transport. Environmentally, the primary climate benefit of this pathway is derived directly from agricultural substitution, which mitigates the significant life cycle emissions associated with commodity imports. This indirect benefit complements the direct carbon fixation from the microalgae (~39 Mt. CO₂/yr). This study concludes that by creating tangible value through agricultural commodity substitution, the strategic co-deployment of microalgae with CCS offers a more robust and economically viable pathway toward the deep decarbonization of the coal power sector.

中国燃煤电厂（CFPPs）采用传统的碳捕集与封存（CCS）技术受到高成本和二氧化碳源与地质封存地点之间的地理不匹配的阻碍。本研究评估了将CCS与现场微藻利用相结合的混合策略，提出了一种同时解决碳减排和提高国内商品生产的新解决方案。该过程将捕获的二氧化碳转化为高价值的生物质，创造了碳密集型农业进口的直接替代品，并加强了国家饲料安全。开发了一个空间明确的技术经济模型，以评估508个低于50%和85%国家减排目标的cfp的双重效益战略。结果显示出令人信服的经济优势。在85%的缓解水平下，混合方法每年可减少49亿美元（5.3%）的总成本，这一优势得益于生物质价值链的收入和避免长距离二氧化碳运输。在环境方面，这一途径的主要气候效益直接来自农业替代，它减轻了与商品进口相关的重大生命周期排放。这种间接效益补充了微藻的直接固碳作用（~39 Mt. CO2/年）。本研究的结论是，通过农产品替代创造有形价值，微藻与CCS的战略联合部署为煤电行业的深度脱碳提供了一条更稳健、更经济可行的途径。

Social life cycle assessment (S-LCA) is increasingly applied to evaluate the social impacts of products and organizations. Primary data is preferred for S-LCA as it is specific to the social impacts of the product system under study which can vary greatly depending on the actors involved. However, primary data-based S-LCAs still face many methodological challenges.

A systematic literature review was conducted to review the methodological challenges and potential solutions described in primary data-based S-LCA case studies. 68 case studies were identified and included for an in-depth analysis. 65 challenges and 54 solutions were grouped to the four phases: goal and scope, social life cycle inventory, impact/performance assessment, and interpretation.

Challenges include relating the defined functional unit to the results and including social impact data for the background system to fully cover the life cycle perspective. Data collection also poses challenges with potential bias and varying perspectives expressed during interviews. There is a lack of standardized reference scales, leading to differences in data collection and results. Further, S-LCA practitioners employ various scoring systems and weighting factors, making it challenging to achieve consistency across assessments. There is also significant variation in how transparent case studies were regarding methodological choices.

The identified challenges impact the consistency and comprehensiveness of S-LCA results, thereby emphasizing the need for methodological developments and consistent application. Recognizing and addressing these challenges is essential for enhancing the practical relevance of S-LCA in industry. This study provides recommendations for good practices to ensure the quality of S-LCA moving forwards.

社会生命周期评价（S-LCA）越来越多地应用于评价产品和组织的社会影响。S-LCA首选原始数据，因为它特定于所研究的产品系统的社会影响，这可能因所涉及的行动者而有很大差异。然而，基于原始数据的s - lca仍然面临许多方法上的挑战。我们进行了一项系统的文献综述，以回顾基于原始数据的S-LCA案例研究中所描述的方法挑战和潜在解决方案。确定了68个案例研究，并列入进行深入分析。65项挑战和54项解决方案分为四个阶段：目标和范围、社会生命周期清单、影响/绩效评估和解释。挑战包括将已定义的功能单元与结果联系起来，并包括背景系统的社会影响数据，以完全覆盖生命周期视角。数据收集也带来了潜在的偏见和在采访中表达的不同观点的挑战。由于缺乏标准化的参考量表，导致数据收集和结果存在差异。此外，S-LCA从业者使用各种评分系统和加权因素，使得在评估中实现一致性具有挑战性。在方法选择方面，案例研究的透明度也存在显著差异。已确定的挑战影响了S-LCA结果的一致性和全面性，因此强调了开发方法和一致应用的必要性。认识和解决这些挑战对于提高S-LCA在工业中的实际相关性至关重要。本研究提供了良好的实践建议，以确保S-LCA的质量向前发展。

Traceability in Sustainable Agribusiness has caught the attention of academia. However, current knowledge is fragmented, lacking theoretical grounding. This study consolidates scientific production on the subject and proposes an agenda for future studies. We analyzed 73 articles from the Scopus database, using the Antecedents, Decisions and Outcomes and Theory, Context and Methods frameworks (ADO-TCM). The synthesis reveals that antecedents center primarily on actors across the supply chain and technological mechanisms, with approximately 80% of the studies relying on Blockchain-based systems as the dominant technological antecedent. Product-related antecedents are concentrated in cattle and derived products, frequently associated with circular-economy practices and environmental sustainability. The main decision variables involve fraud prevention, regulatory compliance, value generation, and market relationships. Outcomes are linked to enhanced trust and product quality. This review advances understanding of how traceability can act as a systemic sustainability mechanism within agribusiness, supporting environmental, economic, and social goals across the life cycle of food production and supply chains. The proposed research agenda highlights the need for more robust theoretical integration, methodological diversity, and explicit application of life cycle perspectives to strengthen the role of sustainability in advancing sustainable production and consumption.

可持续农业企业的可追溯性问题引起了学术界的关注。然而，目前的知识是碎片化的，缺乏理论基础。这项研究巩固了有关该主题的科学成果，并提出了未来研究的议程。我们分析了来自Scopus数据库的73篇文章，使用了前事、决策和结果以及理论、背景和方法框架（ADO-TCM）。综合表明，前因主要集中在供应链和技术机制中的参与者上，大约80%的研究依赖于基于区块链的系统作为主要的技术前因。与产品相关的前因集中在牛和衍生产品中，通常与循环经济实践和环境可持续性有关。主要的决策变量包括欺诈预防、法规遵从、价值产生和市场关系。结果与增强的信任和产品质量有关。这篇综述促进了对可追溯性如何在农业综合企业中作为一种系统可持续性机制的理解，支持食品生产和供应链整个生命周期的环境、经济和社会目标。拟议的研究议程强调需要更有力的理论整合、方法多样性和生命周期观点的明确应用，以加强可持续性在促进可持续生产和消费中的作用。

China is actively exploring the transformation towards a resource-saving economic structure, but research on how to synergistically manage the three basic resources of water, energy and food (WEF) through structural adjustment remains lacking. Here, this study innovatively integrates the multi-regional input-output model with the Sherman-Morrison-Woodbury formula-based elasticity analysis. Based on this, by quantifying the effects of marginal adjustments in intermediate inputs, regional trade, and final demand structures, we identify resource synergistic governance leverage spots that consider economic impacts. The results show that there are 73 efficient synergistic governance spots for WEF at the national level, including 14 leverage spots with low economic impact and high resource governance. The agri-food system (i.e. agricultural products, food and tobacco sector) is the most important leverage spot for structural adjustment, followed by energy-intensive sectors such as construction and chemical products, especially in key provinces such as Hebei, Shanxi, Inner Mongolia, Shandong, Henan, and Xinjiang. To avoid obvious economic shocks, structural adjustment should prioritize sectoral intermediate inputs, cross regional trade, and final demand rather than regional self-supply. Furthermore, we identified 116 structural adjustments with low resource pressure and high economic promotion effects that cover 28 provinces and exhibit significant eastern spatial agglomeration. These spots mainly involve the final demand structure of high value-added products, especially household consumption and fixed capital formation of other services. Based on these findings, we can provide some forward-looking insights for balancing resource governance and economic development through structural adjustment.

中国正在积极探索向资源节约型经济结构转型，但如何通过结构调整协同管理水、能源和粮食三种基本资源的研究还很缺乏。本研究创新性地将多区域投入产出模型与基于Sherman-Morrison-Woodbury公式的弹性分析相结合。在此基础上，通过量化中间投入、区域贸易和最终需求结构的边际调整效应，我们确定了考虑经济影响的资源协同治理杠杆点。结果表明：在国家层面上，世界经济论坛存在73个高效协同治理点，其中经济影响低、资源治理高的杠杆点有14个；农业食品系统（即农产品、食品和烟草行业）是结构调整最重要的杠杆点，其次是建筑和化工等高耗能行业，特别是在河北、山西、内蒙古、山东、河南和新疆等重点省份。为避免明显的经济冲击，结构调整应优先考虑部门间的中间投入、跨区域贸易和最终需求，而不是区域自我供给。此外，我们还发现了116个资源压力小、经济促进效应强的结构调整，这些结构调整覆盖28个省份，具有显著的东部空间集聚性。这些点主要涉及高附加值产品的最终需求结构，特别是家庭消费和其他服务的固定资本形成。基于这些发现，我们可以为通过结构调整平衡资源治理与经济发展提供一些前瞻性的见解。

The EU Battery Regulation stipulates that, beginning in 2031, all electric vehicle (EV) batteries placed on the EU market must contain certain shares of recycled materials. However, the involvement of non-EU battery producers and recyclers makes that such requirements may not effectively stimulate domestic recycling due to cross-border trade flows. To examine this issue, this study develops a dynamic material flow analysis to project global demand and end-of-life volumes of lithium, cobalt, and nickel from EV batteries. Based on these projections, recycled material flows are traced across six stages from retirement to reuse, distinguishing whether processes occur within or outside the EU. The effectiveness of the regulation is then assessed using the minimum battery collection rate required for compliance. Results indicate that under the business as usual (BAU) scenario, EU demand for lithium, nickel, and cobalt will increase from 17.0 kt, 86.8 kt, and 13.0 kt in 2031 to 25.8 kt, 131.3 kt, and 19.7 kt in 2040. If the EU is considered a self-sufficient market, meeting the requirements would require collection rates for lithium, cobalt, and nickel of 42.5%, 44.2%, and 124.9% in 2031–2035, and 31.3%, 40.5%, and 72.7% in 2036–2040. Building sufficient cathode material production capacity within the EU is crucial for achieving the recycling targets, as it represents the key link for utilizing recovered materials. We argue that more flexible mechanisms should be adopted in the Battery Regulation that reflect evolving chemistries, shifting retirement volumes, and self-sufficiency of cathode production and transboundary material flows.

欧盟电池法规规定，从2031年开始，所有投放欧盟市场的电动汽车（EV）电池必须含有一定比例的回收材料。然而，由于跨境贸易流动，非欧盟电池生产商和回收商的参与使得此类要求可能无法有效刺激国内回收。为了研究这个问题，本研究开发了一个动态材料流分析，以预测电动汽车电池中锂、钴和镍的全球需求和报废量。基于这些预测，从报废到再利用的六个阶段追踪了回收材料的流动，区分了这些过程是发生在欧盟内部还是外部。然后使用合规所需的最小电池收集率来评估法规的有效性。结果表明，在一切照旧（BAU）的情况下，欧盟对锂、镍和钴的需求将从2031年的17.0 kt、86.8 kt和13.0 kt增加到2040年的25.8 kt、131.3 kt和19.7 kt。如果欧盟被认为是一个自给自足的市场，要满足要求，锂、钴和镍的回收率将在2031-2035年分别为42.5%、44.2%和124.9%，在2036-2040年分别为31.3%、40.5%和72.7%。在欧盟内部建立足够的阴极材料生产能力对于实现回收目标至关重要，因为它是利用回收材料的关键环节。我们认为，在电池法规中应该采用更灵活的机制，以反映不断变化的化学成分、不断变化的退役量、阴极生产的自给自足和跨境材料流动。

The increasing utilization of bamboo as a sustainable resource has driven the rapid expansion of bamboo-based industries, resulting in significant residue generation that is often managed unsustainably through open burning. This study presents a cradle-to-gate life cycle assessment of four management scenarios: open burning (baseline), biochar-to-soil, biomass-to-energy, and pellet-to-energy based on a functional unit of 1000 t of bamboo residue treated. Results indicate open burning exhibits the highest human health (5.69 DALY) and ecosystem burdens (1.50 × 10⁻³ species.year). The biochar-to-soil scenario achieves substantial climate benefits with a net global warming impact of 465,000 kg CO₂ eq and reduces health impacts by 75% to 1.43 DALY. However, residue-to-energy scenarios demonstrate superior overall performance by displacing fossil-based electricity. The pellet-to-energy pathway delivers the most comprehensive benefits: net health improvement of 0.82 DALY, ecosystem gains of 9.16 × 10⁻³ species.year, and resource conservation amounting to 77,509 USD₂₀₁₃, outperforming biomass-to-energy due to higher efficiency. Sensitivity analysis reveals a critical inflection point: while bioenergy is superior in the current fossil-dependent context, biochar-to-soil becomes increasingly competitive for ecosystem quality as the electricity grid decarbonizes. Although limited by the availability of primary inventory data, these findings indicate that while residue-to-energy offers maximum immediate mitigation, biochar-to-soil provides a decentralized, long-term solution for ecosystem restoration. The results support circular bioeconomy strategies for sustainable bamboo residue management and inform policy frameworks for agricultural waste valorization in developing countries, simultaneously addressing waste management, climate mitigation, and resource recovery objectives.

竹子作为一种可持续资源的利用日益增加，推动了以竹子为基础的产业的迅速扩张，导致大量残留物的产生，这些残留物往往通过露天焚烧进行不可持续的管理。本研究基于1000t竹渣处理的功能单位，对四种管理方案进行了从摇篮到门的生命周期评估：露天燃烧（基线）、生物炭制土、生物质制能和颗粒制能。结果表明，露天焚烧具有最高的人类健康（5.69 DALY）和生态系统负担（1.50 × 10−3种.年）。生物炭转化为土壤的情景实现了巨大的气候效益，全球变暖的净影响为465,000千克二氧化碳当量，将健康影响降低75%，降至1.43 DALY。然而，通过取代化石燃料发电，残留物转化为能源的方案显示出更优越的整体性能。颗粒转化为能源的途径提供了最全面的效益：净健康改善0.82 DALY，生态系统收益9.16 × 10−3种。2013年，节约资源77,509美元，由于效率更高，优于生物质能源。敏感性分析揭示了一个关键拐点：虽然生物能源在当前依赖化石的背景下具有优势，但随着电网脱碳，生物炭转化为土壤对生态系统质量的竞争日益激烈。虽然受到原始清单数据可用性的限制，但这些发现表明，虽然残留物转化为能源提供了最大限度的即时缓解，但生物炭转化为土壤为生态系统恢复提供了一种分散的长期解决方案。研究结果支持可持续竹渣管理的循环生物经济战略，并为发展中国家农业废物增值政策框架提供信息，同时解决废物管理、减缓气候变化和资源回收目标。

In situ thermally enhanced bioremediation (ISTEB) is a promising approach for remediating contaminated soil and groundwater, yet comprehensive quantitative sustainability assessments of its sustainability remain scarce, especially for field-scale applications using hot water injection (TEB-HW) or thermal conductive heating (TEB-TCH). This study addressed this gap by developing the first fully quantitative sustainability framework integrating life cycle assessment (LCA) with best management practices (BMPs), comprising 108 indicators derived from extensive literature review and policy analysis. Using full-scale operational data from ISTEB implementations, we quantified the environmental, economic, and social performance of TEB-HW and TEB-TCH relative to conventional thermal treatment (TCH only). Results show that compared with TCH only, TEB-HW and TEB-TCH reduced carbon emissions by 78% and 31%, and achieved cost savings of 72% and 38%, while also improving community engagement and satisfaction. Normalized multi-criteria sustainability scores indicate overall performance gains of 31% and 13% compared to TCH only. Further optimization of BMPs, such as electric vehicle transport, green injectates, and renewable energy integration, could enhance ISTEB sustainability by up to 45%. These findings provide novel evidence for the practical viability and environmental benefits of ISTEB, offering actionable strategies for low-carbon, cost-effective, and socially acceptable remediation that align with sustainable production principles and contribute toward global net-zero carbon goals in contaminated site management.

原位热强化生物修复（ISTEB）是修复污染土壤和地下水的一种很有前途的方法，但对其可持续性的全面定量评估仍然缺乏，特别是对于使用热水注入（TEB-HW）或导热加热（TEB-TCH）的现场规模应用。本研究通过开发第一个将生命周期评估（LCA）与最佳管理实践（BMPs）结合起来的完全定量的可持续性框架，解决了这一差距，该框架包括108个指标，这些指标来自广泛的文献回顾和政策分析。利用ISTEB实施的全面运行数据，我们量化了相对于传统热处理（仅限TCH）的TEB-HW和TEB-TCH的环境、经济和社会绩效。结果显示，与单纯的粤港澳走廊相比，粤港澳走廊和粤港澳走廊分别减少了78%和31%的碳排放，节约了72%和38%的成本，同时提高了社区参与度和满意度。标准化的多标准可持续性得分表明，与TCH相比，总体绩效提高了31%和13%。进一步优化bmp，如电动汽车运输、绿色注入和可再生能源整合，可以将ISTEB的可持续性提高45%。这些发现为ISTEB的实际可行性和环境效益提供了新的证据，为符合可持续生产原则的低碳、高成本效益和社会可接受的补救措施提供了可操作的策略，并有助于实现污染场地管理的全球净零碳目标。

The rapid growth of the digital industry drives uneven global environmental and socioeconomic impacts, underscoring the need for comprehensive supply-chain assessments to guide sustainable digitalization. Using a multi-regional input-output model, we present a supply-chain-based quantitative evaluation of the digital industry's impacts on 12 SDGs across 164 economies from 1995 to 2021 and analyze the balance between economic benefits and environmental costs. We find that the digital industry contributed over 6 % to global socioeconomic development but less than 6 % to environmental impacts. However, substantial shares of air pollutants (4.8–5.9 %) and mineral resource use (3.3–4.5 %) highlight the need for sustainability strategies beyond decarbonization. Digital manufacturing dominates environmental footprints, while service-oriented sectors have expanded rapidly since 2015. Environmental and social burdens are concentrated in high-middle SDI economies, whereas high-SDI economies capture the majority of economic benefits. This imbalance is reflected in global Gini indices above 0.4, indicating substantial inequality in how digital industries distribute environmental costs and economic gains. Since 2008, high-SDI economies have decoupled growth from environmental harm, while low- and middle-SDI economies face increasing environmental pressures. Structural decomposition analysis shows that between 2008 and 2021, the contribution of output expansion to environmental growth fell to below 9 % per year. Improvements in environmental intensity and production structure, particularly in higher-SDI regions, further reduced global environmental impacts. These findings highlight the urgent need for broader environmental indicators in evaluating digital sustainability and the importance of strengthening supply-chain mitigation measures across the digital industry.

数字产业的快速增长导致全球环境和社会经济影响不平衡，因此需要进行全面的供应链评估，以指导可持续数字化。本文采用多区域投入产出模型，对1995年至2021年164个经济体中数字产业对12项可持续发展目标的影响进行了基于供应链的定量评估，并分析了经济效益与环境成本之间的平衡。我们发现，数字产业对全球社会经济发展的贡献率超过6%，但对环境影响的贡献率不到6%。然而，大量的空气污染物（4.8 - 5.9%）和矿产资源的使用（3.3 - 4.5%）凸显了除脱碳之外的可持续发展战略的必要性。数字制造业主导着环境足迹，而服务业自2015年以来迅速扩张。环境和社会负担集中在中高SDI经济体，而高SDI经济体获得了大部分经济效益。这种不平衡反映在全球基尼系数高于0.4上，表明数字产业在如何分配环境成本和经济收益方面存在严重不平等。自2008年以来，高sdi经济体的增长与环境危害脱钩，而低和中等sdi经济体面临越来越大的环境压力。结构分解分析表明，2008年至2021年间，产出扩张对环境增长的贡献率降至每年9%以下。环境强度和生产结构的改善，特别是在高sdi区域，进一步减少了全球环境影响。这些发现突出表明，在评估数字可持续性时迫切需要更广泛的环境指标，以及加强整个数字产业供应链缓解措施的重要性。
