The deployment of Conventional Ground-Mounted Photovoltaic (CGMPV) systems on farmland creates intense land-use competition with agriculture. Agrivoltaic (APVs) systems present a promising solution, yet the environmental viability of different designs remains insufficiently understood, hindering their strategic deployment. This study addresses this gap by presenting the first Life Cycle Assessment (LCA) benchmarking four bifacial APV systems, including fixed vertical, interspace, overhead single-axis, and overhead dual-axis systems with varying row pitch. These systems are compared against a bifacial CGMPV system (baseline scenario) and national electricity grid mixes, country-specific combinations of fossil, nuclear, and renewable sources, across north to south of Europe. A combined LCA method is applied, with attributional LCA evaluating PV components from cradle-to-end-of-use across ten impact categories, and a consequential approach addressing agricultural land-use change contributions to climate change category.

Results demonstrate that APV systems significantly outperform national electricity grids across nine impact categories, achieving 8–111 times lower environmental impacts. The interspace single-axis system emerged as the most optimal configuration with the lowest greenhouse gases (GHG) emissions (11–20 g CO_2eq/kWh), 57 % lower particulate matter, 48 % lower acidification, and 27 % lower eutrophication versus other APVs. The overhead dual-axis system showed the highest impacts (16–29 g CO_2eq/kWh), driven primarily by steel consumption in mounting structures. Monte Carlo Analysis confirmed that performance rankings are statistically robust. All APV systems showed 3.5–9.6 times higher mineral resource consumption than electricity grid mixes, highlighting a critical trade-off for sustainable resource management. These findings demonstrate that while APV systems can synergize food-energy systems with superior performance in most environmental categories, mineral resource intensity remains challenging, with material-efficient configurations essential for minimizing trade-offs.

传统的地面光伏（cmpv）系统在农田上的部署与农业产生了激烈的土地利用竞争。农业光伏（apv）系统提供了一个很有前途的解决方案，但不同设计的环境可行性仍然没有得到充分的了解，阻碍了它们的战略部署。本研究通过首次生命周期评估（LCA）对四种双面APV系统进行基准测试，解决了这一差距，包括固定垂直、间隔、架空单轴和架空双轴系统，这些系统具有不同的排距。将这些系统与双面cmpv系统（基线情景）和国家电网组合进行比较，这些电网组合是横跨欧洲北部到南部的化石能源、核能和可再生能源的具体国家组合。本文采用了一种综合的LCA方法，其中归因LCA评估了光伏组件从摇篮到使用终端的十个影响类别，并采用相应的方法解决了农业土地利用变化对气候变化的贡献类别。结果表明，APV系统在9个影响类别中显著优于国家电网，实现了8-111倍的环境影响。与其他apv相比，空间单轴系统具有最低的温室气体（GHG）排放（11-20 g co2当量/千瓦时），降低57%的颗粒物，48%的酸化和27%的富营养化。架空双轴系统显示出最大的影响（16-29 g二氧化碳当量/千瓦时），主要是由安装结构的钢材消耗驱动的。蒙特卡洛分析证实，性能排名在统计上是稳健的。所有APV系统的矿物资源消耗都是电网混合系统的3.5-9.6倍，突出了可持续资源管理的关键权衡。这些发现表明，虽然APV系统可以在大多数环境类别中具有卓越性能的食物-能源系统协同作用，但矿物资源强度仍然具有挑战性，材料效率配置对于最大限度地减少权衡至关重要。

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。

Single-use disposable cups are a major contributor to plastic waste due to their widespread use and limited recyclability. In response, policymakers are introducing measures to reduce their consumption and promote reusable alternatives. This study employs a discrete choice experiment with a nationally representative sample to evaluate how regulatory incentives (charges, discounts), persuasive strategies (environmental information prompts), and motivational drivers (perceived threat severity and vulnerability, maladaptive response rewards, response efficacy, self-efficacy, and response costs) influence consumer preferences for single-use, refillable, and returnable cups. We find that a mandatory charge of 25–30 pence is required to reduce disposable cup selection by 50 %, whereas achieving a similar reduction through discounts requires incentives of at least 70 pence. Environmental information prompts had limited effect, slightly increasing preference for returnable cups when offered alone, but not when both reusable options were present. Consumers who were more likely to choose reusable options perceived greater environmental threat, believed their actions to be effective, and felt more capable of acting, supporting Protection Motivation Theory as a valuable framework for understanding behavioural drivers in circular consumption. Policy wise, charges are more efficient than discounts for shifting choices. To increase uptake of reusable cups pair a moderate charge with returnable and refillable options, keep deposits modest, and prioritise practical features that make reuse easy (e.g., simple return points, washing provision) over information alone.

由于一次性杯子的广泛使用和有限的可回收性，它们是塑料垃圾的主要来源。作为回应，政策制定者正在采取措施减少它们的消耗，并推广可重复使用的替代品。本研究采用具有全国代表性样本的离散选择实验来评估监管激励（收费、折扣）、说服策略（环境信息提示）和动机驱动因素（感知威胁严重性和脆弱性、适应不良反应奖励、反应效能、自我效能和反应成本）如何影响消费者对一次性、可再填充和可回收杯子的偏好。我们发现，强制收取25-30便士的费用才能使一次性杯子的选择减少50%，而通过折扣实现类似的减少则需要至少70便士的激励。环境信息提示的效果有限，当单独提供可回收杯子时，会略微增加对可回收杯子的偏好，但当两种可重复使用的杯子都存在时，则不会。更有可能选择可重复使用选项的消费者认为环境威胁更大，相信他们的行动是有效的，并且觉得更有能力采取行动，这支持了保护动机理论作为理解循环消费行为驱动因素的有价值框架。从政策上讲，收费比折扣更有效。为了增加可重复使用杯子的使用率，将适度的充电与可回收和可再填充的选择相结合，保持适度的存款，并优先考虑易于重复使用的实用功能（例如，简单的回收点，洗涤提供），而不仅仅是信息。

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。

Ecolabels play a crucial role in achieving responsible production and consumption. Current LCA-based food ecolabels suffer from inconsistent methodologies, leading to significant variability in the estimated sustainability performance for the same product. To address the methodological challenges, we investigated 31 food ecolabels based on LCA from the EU countries, Norway, the UK, and Switzerland. Data were collected through questionnaires and systematically analysed. The analysis revealed significant heterogeneity in the methodologies behind the different food ecolabels, with variations in functional units, system boundaries, impact categories assessed, etc. Ecolabels exhibited a wide range of label formats regarding gradation type, score/value type, and impact category aggregation type, showcasing diverse approaches to communicating sustainability performance. The Product Environmental Footprint (PEF) and some PEF Category Rules (PEFCRs) are available for the LCA methodology used for the calculation, even though they need to be further tailored. However, no standards or guidelines are available for guiding the communication of LCA results with consumers in term of label formats at the EU level. Finally, the identified methodological challenges were discussed, emphasising the need for regulatory standards to address the diversity in ecolabeling practices and to guide the development of a more uniform and transparent framework for food ecolabels.

生态标签在实现负责任的生产和消费方面发挥着至关重要的作用。目前基于lca的食品生态标签的方法不一致，导致同一产品的估计可持续性表现存在显著差异。为了解决方法上的挑战，我们调查了来自欧盟国家、挪威、英国和瑞士的31个基于LCA的食品生态标签。通过问卷调查收集数据并进行系统分析。分析显示，不同食品生态标签背后的方法存在显著的异质性，在功能单位、系统边界、评估的影响类别等方面存在差异。生态标签展示了各种各样的标签格式，包括分级类型、得分/价值类型和影响类别聚合类型，展示了传达可持续发展绩效的不同方法。产品环境足迹（PEF）和一些PEF类别规则（pefcr）可用于用于计算的LCA方法，尽管它们需要进一步定制。然而，就欧盟层面的标签格式而言，没有标准或指南可用于指导LCA结果与消费者的沟通。最后，讨论了确定的方法挑战，强调需要制定监管标准来解决生态标签实践的多样性，并指导制定更统一和透明的食品生态标签框架。

Food packaging is often criticised for its environmental impact. However, it can play a crucial role in reducing avoidable waste generated during the consumption of food products. Relying on a lifecycle analysis, this study explores the trade-off between the environmental impacts of packaging and its potential to prevent food waste. In particular, commodity-specific waste scenarios are compared for packaged and unpackaged options across different household sizes, as household composition influences consumption rates and the likelihood of food spoilage. Results show that, when food waste rates are equal, packaged options generally have higher environmental impacts due to added processing and packaging materials. However, packaged alternatives may offer a preferable option when avoidable food waste is reduced below threshold levels that are commodity and household-size-specific. In particular, single-person households, currently over one-third of European households, are most at risk of exceeding these thresholds, implying that right-sized, convenience-oriented packaging could deliver net benefits if it effectively cuts waste. Conversely, larger households generally minimise impacts by choosing unpackaged produce. The findings underline three priorities: (i) incorporate commodity- and household-level waste heterogeneity into lifecycle assessment (LCA) and policy analyses; (ii) tailor packaging design to smaller households to realise waste-reduction potential; and (iii) refine food-waste statistics to support evidence-based decisions.

食品包装经常因其对环境的影响而受到批评。然而，它可以在减少食品消费过程中产生的可避免的浪费方面发挥关键作用。依靠生命周期分析，本研究探讨了包装对环境的影响及其防止食物浪费的潜力之间的权衡。特别是，由于家庭构成影响消费率和食物变质的可能性，对不同家庭规模的包装和非包装选择的特定商品浪费情况进行了比较。结果表明，当食物浪费率相等时，由于添加了加工和包装材料，包装选项通常具有更高的环境影响。然而，当可避免的食物浪费减少到特定商品和家庭规模的阈值水平以下时，包装替代品可能是一个较好的选择。特别是，目前超过三分之一的欧洲家庭的单身家庭，最有可能超过这些阈值，这意味着，如果尺寸合适，以方便为导向的包装能有效减少浪费，就能带来净效益。相反，较大的家庭通常通过选择未包装的农产品来减少影响。研究结果强调了三个优先事项：(i)将商品和家庭层面的废物异质性纳入生命周期评估和政策分析；（ii）设计适合小家庭使用的包装，以发挥减少废物的潜力；（三）完善食物浪费统计数据，以支持基于证据的决策。

The challenge of reversing the vicious cycle between climate change and food systems is attracting considerable attention. However, building a sustainable dietary system in line with China's national conditions remains a challenging endeavor. By developing a multi-regional input-output model at high sector resolution for China encompassing 31 provinces and 163 sectors, we investigate five diet-related environmental footprint indicators, assess the environmental impacts of dietary consumption and design five possible future dietary strategies to explore their potential environmental mitigation effects in China. Our findings revealed significant spatial heterogeneity in the environmental footprints of food consumption adopting different dietary strategies. The comprehensive dietary strategy could reduce environmental pressure by 3 %–15 %. The most significant effect would be a reduction by 146.82 Mt CO₂eq in greenhouse gas (GHG) footprint and 33.71bcm in water use footprint relative to the business-as-usual scenario, equivalent to about 10 % of current agricultural GHG emissions and water use. This environmental benefit is largely due to reduced cereals and red meat consumption. Achieving a sustainable dietary shift would require the concerted efforts of diverse stakeholders.

扭转气候变化与粮食系统之间恶性循环的挑战正在引起相当大的关注。然而，构建符合中国国情的可持续饮食体系仍然是一项具有挑战性的工作。通过建立中国31个省163个行业的高部门分辨率的多区域投入产出模型，研究了5个与饮食相关的环境足迹指标，评估了饮食消费的环境影响，并设计了5种可能的未来饮食策略，以探索它们在中国的潜在环境缓解效应。我们的研究结果揭示了不同饮食策略对食物消费环境足迹的显著空间异质性。综合饮食策略可使环境压力降低3% ~ 15%。最显著的影响是，与一切照旧情景相比，温室气体（GHG）足迹减少14682亿吨二氧化碳当量，用水足迹减少337.1亿立方米，相当于目前农业温室气体排放和用水的10%左右。这种环境效益主要是由于减少了谷物和红肉的消费。实现可持续的饮食转变需要各利益攸关方的共同努力。

Exploring behavioural intentions behind biochar technology adoption in agriculture 探索农业采用生物炭技术背后的行为意图

This study examines Northern Italian farmers' intentions to adopt biochar by applying the Technology Acceptance Model and an extended specification tailored to sustainability contexts. A cross-sectional telephone survey of farmers (n = 131) was analysed using partial least squares structural equation modelling. We estimate a baseline model that includes perceived usefulness, perceived ease of use, subjective norm, image, job relevance, output quality, and result demonstrability, as well as an extended model that adds climate-change awareness, perceived economic value (price–value), and perceived external control/support.

Across specifications, intention to adopt is positively related to perceived usefulness and perceived ease of use. In the extended model, the economic value proposition emerges as the most salient antecedent of perceived usefulness, with additional contributions from output quality, result demonstrability, and awareness of climate change. By contrast, social-influence pathways (subjective norm, image) are weak or inconsistent.

The exploratory findings suggest that, in a voluntary setting with generally low prior knowledge, farmers' intentions are most consistent with instrumental, value-for-money judgments and the perceived simplicity of implementation, rather than social endorsement. Interpretations are correlational and are bound to a sample of Northern Italian farmers. Practical implications include demonstrating credible agronomic and economic benefits, reducing perceived complexity, and ensuring visible support for early adopters. Future research should validate these patterns longitudinally and in other countries and awareness stages.

本研究通过应用技术接受模型和针对可持续性背景量身定制的扩展规范，考察了意大利北部农民采用生物炭的意图。采用偏最小二乘结构方程模型对农民进行横断面电话调查（n = 131）。我们估计了一个基线模型，该模型包括感知有用性、感知易用性、主观规范、形象、工作相关性、输出质量和结果可论证性，以及一个扩展模型，该模型增加了气候变化意识、感知经济价值（价格价值）和感知外部控制/支持。在各个规范中，采用的意向与感知到的有用性和感知到的易用性正相关。在扩展模型中，经济价值主张作为感知有用性的最显著先决条件出现，产出质量、结果可论证性和对气候变化的认识也做出了额外贡献。相比之下，社会影响途径（主观规范、形象）较弱或不一致。探索性研究结果表明，在通常先验知识较低的自愿环境中，农民的意图与工具性、物有所值的判断和执行的感知简单性最一致，而不是社会认可。解释是相关的，并且与意大利北部农民的样本有关。实际意义包括展示可靠的农业和经济效益，减少感知的复杂性，并确保对早期采用者的可见支持。今后的研究应纵向地、在其他国家和认识阶段验证这些模式。

A well-executed life cycle assessment requires thorough data collection across all relevant processes, combined with advanced data analysis. Common data-related issues in life cycle assessment research include the absence of necessary data, low data quality, inconsistencies, uncertainty, and failure to account for variations over time and location. In this context, data science, the discipline of extracting meaningful insights from data, has the potential to address these challenges. While the integration of data science with life cycle assessment holds significant potential, best use cases depend on the goal of the study, as well as the data type and volume required, underscoring the necessity of reviewing the intersection of data science and life cycle assessment. This study used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) method to identify literature addressing the use of data science elements to support life cycle assessment. It evaluated which data science techniques are appropriate for specific life cycle assessment stages or problem areas and the strengths and weaknesses of current data science applications in life cycle assessment. Key opportunities identified revolve around solutions for dealing with missing or poor-quality data, expensive/prohibitive data collection, and improving the accuracy of life cycle assessment results. The currently most feasible pathways appear to involve use of machine learning techniques, as these types of studies were the most conducted and generated tangible results. Extreme gradient boosting, random forest, and artificial neural networks were particularly prominent algorithm choices. Data collection and transferability using ontologies and semantic tools were also highlighted as important strategies for improving data flow in life cycle assessment, including the integration of a wide variety of databases and non-life cycle assessment data.

执行良好的生命周期评估需要在所有相关过程中进行全面的数据收集，并结合先进的数据分析。生命周期评估研究中常见的与数据相关的问题包括缺乏必要的数据、数据质量低、不一致、不确定性以及未能解释随时间和地点的变化。在这种背景下，数据科学，从数据中提取有意义的见解的学科，有可能解决这些挑战。虽然数据科学与生命周期评估的整合具有巨大的潜力，但最佳用例取决于研究的目标，以及所需的数据类型和数量，这强调了审查数据科学与生命周期评估交叉的必要性。本研究使用系统评价和荟萃分析的首选报告项目（PRISMA）方法来识别涉及使用数据科学元素来支持生命周期评估的文献。它评估了哪些数据科学技术适合特定的生命周期评估阶段或问题领域，以及当前数据科学应用在生命周期评估中的优势和劣势。确定的关键机会围绕着处理缺失或低质量数据、昂贵/令人望而却步的数据收集以及提高生命周期评估结果准确性的解决方案。目前最可行的途径似乎涉及使用机器学习技术，因为这些类型的研究进行得最多，并产生了切实的结果。极端梯度增强、随机森林和人工神经网络是特别突出的算法选择。使用本体和语义工具的数据收集和可转移性也被强调为改善生命周期评估中数据流的重要策略，包括各种数据库和非生命周期评估数据的集成。

The European forests are essential in achieving the land use and land-use change (LULUC) related CO₂ removal targets. Adoption of various harvesting practices significantly influences the overall LULUC emissions and removals of forests. In this study, we used the life cycle assessment (LCA) approach to systematically evaluate the land use and land use change-related emissions and removals (GWP_LULUC) of harvested wood raw material. We applied different case study scenarios with different forest management practices in Finland in comparison to the business as usual scenario (one pre-commercial thinning and two commercial thinnings): i) a scenario with no pre-commercial thinning, ii) a scenario with reduced thinning with longer rotation cycle, and iii) a scenario with collection of logging residues. We also explored the effect of management on land occupation. We modeled various scenarios using the MOTTI stand simulation for birch, spruce, and pine, encompassing different vegetation types across various regions of Finland. This was followed by soil carbon modelling using the Yasso07 model to assess the effect of residue collection for spruce. Our analysis indicated that the management effects on GWP_LULUC emissions and removals vary across regions, vegetation types, and management practices. Especially, reduced thinning with longer rotation cycles results in significant carbon removals and lowest land occupation due to the longest rotation cycle (except for birch). The collection of residues leads to small losses of soil organic carbon, but the effect was a negligible factor in the overall GWP of wood raw material. These findings underscore the intricate interplay between regional, species-specific, and management-related factors in shaping the GWP_LULUC of forest-based products.

欧洲森林对于实现与土地利用和土地利用变化（LULUC）相关的二氧化碳去除目标至关重要。采用各种采伐方法显著影响LULUC的总体排放和森林的清除。在本研究中，我们使用生命周期评估（LCA）方法系统地评估了采伐木材原料的土地利用和土地利用变化相关的排放和清除（GWPLULUC）。我们在芬兰应用了不同森林管理实践的不同案例研究情景，与常规商业情景（一次预商业间伐和两次商业间伐）进行了比较：i)不进行预商业间伐的情景，ii)减少间伐并延长轮作周期的情景，以及iii)收集伐木残留物的情景。我们还探讨了管理对土地占用的影响。我们使用MOTTI对桦树、云杉和松树进行林分模拟，模拟了芬兰不同地区的不同植被类型。随后使用Yasso07模型对土壤碳进行建模，以评估云杉残渣收集的效果。我们的分析表明，管理对GWPLULUC排放和清除的影响因地区、植被类型和管理实践而异。特别是，随着轮作周期的延长，间伐的减少会导致显著的碳清除和土地占用的减少，因为轮作周期最长（桦树除外）。废弃物的收集导致土壤有机碳的损失较小，但对木材原料的总体GWP的影响可以忽略不计。这些发现强调了区域、物种特异性和管理相关因素在形成林基产品GWPLULUC中的复杂相互作用。
