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。

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。

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。

Integrating planetary boundaries into safe and sustainable by design framework: A systematic literature review 通过设计框架将地球边界整合为安全和可持续：系统的文献综述

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。

Together, these requirements lay the foundation for a structured, forward-oriented workflow to support actionable PB integration into SSbD.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"60 ","pages":"Pages 64-77"},"PeriodicalIF":9.6,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145120493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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。

Understanding the diverse carbon peaking pathways of different cities are critically important for achieving China's dual carbon goals. To address data limitations, this study introduces a novel Data Alignment Technique to compile the most comprehensive historical carbon emission dataset of 329 Chinese cities from 1992 to 2023. The dynamics of carbon peak—including trajectories, timelines, and driving factors are systematically analysed by integrating machine learning techniques and econometrics models. The findings include: (1) The carbon peaking process at the city level in China was fragmented and asynchronous, as evidenced by the distribution of 213 Non-Peak Cities (64.74 %), 84 Pre-Peak Cities (25.53 %), and 32 Post-Peak Cities (9.73 %). (2) Peak Cities have formed nine distinct carbon peak clusters across the country, primarily driven by the spillover effects of technological innovation and regulatory policies. (3) Emissions in Peak Cities were reduced in stages: first, by energy structure optimization (1995–1999), thereafter, by technological innovation (2005–2019), and recently, by policy regulation and industrial restructuring (2020−2022). (4) The marginal effects of green technology, policy regulation and industrial structure adjustment on carbon exhibited the greatest variability among Non-Peak Cities, with only half of them achieving emission reduction benefits from these measures. These findings underscore the urgent need for coordinated, yet differentiated, climate efforts, particularly to facilitate technological diffusion and enhance policy synergy within the city agglomerations.

了解不同城市不同的碳峰值路径对于实现中国的双碳目标至关重要。为了解决数据的局限性，本研究引入了一种新颖的数据对齐技术，编制了1992 - 2023年中国329个城市最全面的历史碳排放数据集。通过整合机器学习技术和计量经济学模型，系统地分析了碳峰值的动态，包括轨迹、时间线和驱动因素。结果表明：(1)中国城市碳峰值过程具有碎片化和非同步的特征，非峰值城市213个（64.74%），峰值前城市84个（25.53%），峰值后城市32个（9.73%）。②峰值城市在全国范围内形成了9个不同的碳峰值集群，其主要驱动因素是技术创新和监管政策的溢出效应。③高峰城市的减排分阶段进行：首先是能源结构优化（1995-1999年），其次是技术创新（2005-2019年），最近是政策调控和产业结构调整（2020 - 2022年）。(4)绿色技术、政策调控和产业结构调整对碳排放的边际效应在非峰值城市中表现出最大的变异性，只有一半的城市从这些措施中获得了减排效益。这些发现强调了迫切需要协调但有区别的气候努力，特别是促进技术扩散和加强城市群内的政策协同作用。

Sustainable Business Model (SBM) is a strategic approach that integrates sustainability into the core operations and values of organisations. However, scaling SBMs remains a significant challenge due to resource constraints, operational inefficiencies, and stakeholder complexities, emphasising the need for structured frameworks to facilitate this process. This paper introduces the Sustainability Scale-Up Framework (SSF), a comprehensive tool explicitly developed through a design approach to help businesses scale their operations while maintaining alignment with environmental, social, and economic sustainability principles. The SSF was developed iteratively through an extensive literature review, and semi-structured interviews with experts and practitioners of sustainable startups. The SSF's layered structure systematically addresses value creation, operational scalability, stakeholder engagement, and strategic alignment, uniquely integrating value tensions across economic, social, and environmental dimensions to guide the scaling of SBMs. The SSF was validated through a business case workshop where its practical utility based on parameters like usability, flexibility, coherence, and applicability were examined. This paper contributes to SBM, scalability, and strategic design literature by offering insights through a vision-driven framework, providing a novel methodological approach to integrate strategic design principles into scaling processes, and delivering practical tools for businesses, and policymakers to foster sustainable growth for achieving transformative impact.

可持续商业模式（SBM）是一种将可持续发展融入组织核心业务和价值观的战略方法。然而，由于资源限制、操作效率低下和利益相关者的复杂性，扩展SBMs仍然是一个重大挑战，强调需要结构化框架来促进这一过程。本文介绍了可持续发展规模扩大框架（SSF），这是一个通过设计方法开发的综合性工具，旨在帮助企业扩大运营规模，同时保持与环境、社会和经济可持续性原则的一致性。SSF是通过广泛的文献回顾和对可持续创业专家和实践者的半结构化访谈来迭代开发的。SSF的分层结构系统地解决了价值创造、运营可扩展性、利益相关者参与和战略一致性问题，独特地整合了经济、社会和环境维度上的价值紧张关系，以指导sbm的规模。SSF通过一个业务案例研讨会进行了验证，在该研讨会上，基于可用性、灵活性、一致性和适用性等参数对其实际效用进行了检查。本文对SBM、可扩展性和战略设计文献做出了贡献，通过愿景驱动的框架提供了见解，提供了一种新的方法方法，将战略设计原则整合到扩展过程中，并为企业和政策制定者提供了实用工具，以促进可持续增长，实现变革影响。

ISO 14067:2018 mandates accounting for land use and land use change (LULUC) impacts on global warming impact due to carbon stock changes in living biomass, litter, dead organic matter, and soil organic carbon (SOC). Furthermore, the SOC changes are particularly relevant for cropland-based products. Despite methodological advancements, there is still no universally agreed-upon approach on how to evaluate LULUC-related global warming impact within Life Cycle Assessment (LCA), highlighting the need for a standardized approach. This study presents a comprehensive method for assessing SOC dynamics due to land use in LCA, incorporating uncertainties associated with model-based estimations. Using the Tier-2 IPCC Steady State Soil Carbon model, the study analyzed SOC changes in sugarcane cultivation on mineral soils in Thailand. The study examined the effects of land use history across different study periods (T-20, T-50, and T-100 years), as well as the impact of land management practices (full-, reduced-, and no-tillage) and residue management strategies (100 % burnt, 100 % retained, and mixed) on SOC change. While the model study period considerably influenced the initial SOC stocks, the variations in soil organic carbon stock change due to study periods, land management, and residue management practices were statistically not significant. However, the model-associated uncertainties were found to be substantial. The distribution fit assessment revealed that CO₂ emission/removal related flow follows a normal distribution [X ~ N (μ, σ²)]. Our findings highlighted the importance of incorporating ∆SOC into carbon footprint calculations to accurately capture the carbon sequestration potential of soils, which can significantly offset emissions. Neglecting SOC dynamics may lead to an overestimation of CO₂ emissions and an incomplete assessment of net carbon impact. Therefore, given the significant variations observed in global warming impact, integrating SOC considerations into LCAs is essential for improving the precision of environmental evaluations of agriculture-based products.

ISO 14067:2018要求考虑土地利用和土地利用变化（LULUC）对全球变暖影响的影响，这是由于活生物量、凋落物、死有机质和土壤有机碳（SOC）的碳储量变化。此外，SOC变化与基于农田的产品特别相关。尽管方法上取得了进步，但对于如何在生命周期评估（LCA）中评估luluc相关的全球变暖影响，仍然没有普遍认可的方法，这突出了标准化方法的必要性。本研究提出了一种综合评估LCA土地利用引起的有机碳动态的方法，包括与基于模型的估算相关的不确定性。采用Tier-2 IPCC稳态土壤碳模型，分析了泰国矿质土壤中甘蔗种植过程中有机碳的变化。该研究考察了不同研究时期（T-20、T-50和T-100年）土地利用历史的影响，以及土地管理实践（全面、减少和免耕）和残留物管理策略（100%燃烧、100%保留和混合）对土壤有机碳变化的影响。模型研究时段对土壤有机碳储量的影响较大，但不同研究时段、土地管理方式和秸秆管理方式对土壤有机碳储量的影响不显著。然而，发现与模式相关的不确定性是相当大的。分布拟合评价表明，CO2排放/去除相关流量服从正态分布[X ~ N (μ, σ2)]。我们的研究结果强调了将∆SOC纳入碳足迹计算的重要性，以准确捕获土壤的碳固存潜力，这可以显著抵消排放。忽视有机碳动态可能导致对二氧化碳排放量的高估和对净碳影响的不完整评估。因此，考虑到全球变暖影响的显著变化，将有机碳考虑纳入LCAs对于提高农产品环境评价的精度至关重要。
