The diffusion of cooperation among diverse stakeholders in large-scale systems is crucial for achieving socially optimal outcomes. This paper presents a novel framework for modeling how cooperation emerges and diffuses in the management of urban water and reclaimed wastewater resources, particularly in contexts where rivers and groundwater face significant risks from competing stakeholder interests, industrial pollution, and rapid urbanization. The first step toward sustainable management involves identifying stakeholders, their objectives, influence, and roles within the system, alongside analyzing their social network. The paper seeks to develop a cooperation diffusion model by evaluating how stakeholders influence one another's performance. To achieve this goal, the proposed approach combines social network analysis, stakeholder analysis, and social learning assessment. A physical model is used to evaluate water quality and quantity, while a multi-agent model simulates stakeholder behavior and decision-making. Using a linear threshold model (LTM), the cooperation diffusion process is structured and evaluated. The methodology is implemented in the Kan River Basin, which is located in the western region of the Tehran metropolitan area in Iran. The results indicate that promoting cooperation significantly boosts system performance by aligning stakeholder goals and enhancing social benefits. On average, the aquifer level rises by 30 %, whereas the average nitrate concentration decreases by approximately 50 %. These findings underscore the importance of fostering collaboration in the management of complex water resources systems. From a policy perspective, the results suggest that coupling technical interventions such as wastewater reuse with participatory reforms and stronger stakeholder engagement mechanisms is essential for sustainable outcomes. Moreover, empowering bridging actors and formalizing participatory forums can strengthen cooperation and foster long-term social acceptance of water governance strategies.

在大规模系统中，不同利益相关者之间的合作扩散对于实现社会最优结果至关重要。本文提出了一个新的框架，用于模拟合作如何在城市水和再生废水资源管理中产生和扩散，特别是在河流和地下水面临利益相关者利益竞争、工业污染和快速城市化的重大风险的情况下。可持续管理的第一步包括确定利益相关者、他们的目标、影响和在系统中的角色，以及分析他们的社会网络。本文试图通过评估利益相关者如何影响彼此的绩效来建立一个合作扩散模型。为了实现这一目标，本文提出的方法结合了社会网络分析、利益相关者分析和社会学习评估。物理模型用于评价水质和水量，多智能体模型用于模拟利益相关者的行为和决策。利用线性阈值模型（LTM）对合作扩散过程进行了结构化和评价。该方法在位于伊朗德黑兰大都市区西部地区的坎河流域实施。结果表明，促进合作可以通过协调利益相关者目标和提高社会效益来显著提高系统绩效。平均而言，含水层水位上升30%，而平均硝酸盐浓度下降约50%。这些发现强调了在管理复杂水资源系统方面促进合作的重要性。从政策角度来看，研究结果表明，将废水回用等技术干预措施与参与性改革和加强利益相关者参与机制相结合，对于取得可持续成果至关重要。此外，赋予桥梁行为者权力和使参与性论坛正式化可以加强合作，促进社会对水治理战略的长期接受。

Media play a pivotal role in shaping public perceptions of climate change, influencing policy debates and societal responses to environmental challenges. This study investigates the evolution of climate change reporting in China, the UK, and the US from 2014 to 2023, focusing on its impact on public understanding during major global events. Employing Usage Fluctuation Analysis (UFA) and Discourse-Historical Approach (DHA), it provides a quantitative and qualitative examination of variations in the collocational patterns of “climate change”. Our findings reveal that, despite cultural and political differences, climate change reporting in the Chinese, British, and American press shows notable points of convergence, with observable shifts in discourse presentation and public engagement over time. Specifically, Chinese media emphasizes international cooperation and national climate policy, highlighting active engagement and responsibility. The UK media narrative reflects a leadership approach centered on institutional frameworks and international collaboration, while significant events such as Brexit contribute to thematic fragmentation. In contrast, US media discourse is characterized by polarization and sensitivity to political leadership, with shifts between fragmentation and renewed consensus accompanying changes in administration. These insights underscore the complex interplay between socio-political factors and media portrayal of climate change, highlighting the strategic role of media in both mirroring and shaping public discourse and policy. The implications of these findings are significant for stakeholders in environmental communication, policy formulation, and climate governance, emphasizing the need for strategic media engagement to foster a globally informed and proactive response.

媒体在塑造公众对气候变化的看法、影响政策辩论和社会对环境挑战的反应方面发挥着关键作用。本研究调查了2014年至2023年中国、英国和美国气候变化报道的演变，重点关注其在重大全球事件期间对公众理解的影响。采用用法波动分析（UFA）和话语历史方法（DHA），对“气候变化”搭配模式的变化进行了定量和定性的检查。我们的研究结果表明，尽管文化和政治上存在差异，但中国、英国和美国媒体的气候变化报道显示出显著的趋同点，随着时间的推移，话语呈现和公众参与的变化可以观察到。具体而言，中国媒体强调国际合作和国家气候政策，强调积极参与和责任。英国媒体的叙事反映了一种以制度框架和国际合作为中心的领导方式，而英国脱欧等重大事件则助长了主题碎片化。相比之下，美国媒体话语的特点是两极分化和对政治领导的敏感，伴随着政府更迭，分裂和重新达成共识之间的转变。这些见解强调了社会政治因素与媒体对气候变化的描述之间复杂的相互作用，突出了媒体在反映和塑造公共话语和政策方面的战略作用。这些研究结果对环境沟通、政策制定和气候治理的利益相关者具有重要意义，强调了战略性媒体参与的必要性，以促进全球知情和积极的应对。

While the engagement of large corporations in sustainability policy has been widely studied, the potential role of small and medium-sized enterprises (SMEs) in this area remains underexplored. This qualitative study aims to clarify how SMEs can participate in sustainability-related policymaking within the context of political corporate social responsibility (CSR). To that end, interviews were conducted with 14 pioneering Japanese SMEs that had received recognition through one of two government-sponsored award programs for their implementation of the Sustainable Development Goals (SDGs). To analyze the political activities of these firms, this study adopts the framework proposed by Westman et al. (2020), which conceptualizes SME political engagement through formal political participation, activism, civic engagement, and involvement. Based on this framework, the collected data were classified and analyzed to identify how SMEs engage in political processes. The findings reveal that SMEs influence both sustainability policymaking and informal rule-setting within sectors such as production and healthcare, often through participation in advocacy groups and other collective actions. These results suggest that SMEs are not merely passive recipients of policy but have the capacity to shape it through diverse forms of engagement, acting as policy actors. By positioning SMEs as a previously underexamined unit of analysis, the study contributes to the literature on political CSR and sustainability governance, offering a new perspective on the ways in which smaller firms can participate in and help shape public policy, particularly within the sustainability domain.

虽然大公司参与可持续政策的问题已得到广泛研究，但中小型企业在这一领域的潜在作用仍未得到充分探讨。本定性研究旨在阐明中小企业如何在政治企业社会责任（CSR）的背景下参与与可持续发展相关的政策制定。为此，我们采访了14家开创性的日本中小企业，这些企业因实施可持续发展目标（sdg）而获得了两个政府资助的奖励计划之一的认可。为了分析这些企业的政治活动，本研究采用了Westman等人（2020）提出的框架，该框架将中小企业的政治参与概念化为正式的政治参与、行动主义、公民参与和参与。基于这一框架，收集的数据被分类和分析，以确定中小企业如何参与政治进程。研究结果表明，中小企业通常通过参与倡导团体和其他集体行动，影响生产和医疗保健等部门的可持续性政策制定和非正式规则制定。这些结果表明，中小企业不仅是政策的被动接受者，而且有能力通过各种形式的参与，作为政策行动者来塑造政策。通过将中小企业定位为以前未被充分研究的分析单元，该研究为政治企业社会责任和可持续性治理的文献做出了贡献，为小型企业参与和帮助制定公共政策的方式提供了新的视角，特别是在可持续性领域。

Sustainable agriculture depends on effective water management in arid and semi-arid regions facing water scarcity and salinity challenges. This study develops a multi-scale system dynamics model to evaluate the interactions between irrigation policy scenarios and regional economic balances across the Shapour River Basin, comparing infrastructure-oriented, demand management, and hybrid scenarios. The model simulates salinity accumulation and soil-water dynamics at the district level, while capturing basin-wide crop yields, agricultural economics, and water use. Computational results reveal that while demand management alone (scenario 4) outperforms the first three irrigation technology-focused scenarios (scenarios 1–3) with 10 % more enhancements in net economic profit and water economic value and reflects rebound effect of these infrastructure-only policies, the hybrid scenario (scenario 5) that combines both demand management and technology improvement proves most effective, delivering the highest economic returns with 77 % improvements and achieving significant reductions in water use up to 56 % compared to the status quo. These findings showcase the diminishing effectiveness of infrastructure-focused approaches while highlighting the superior performance of the integrated strategies. This demonstrates that the combination of demand management, irrigation technology, and regional economic equity leads to sustainable outcomes. They offer not only actionable guidance for policymakers in the study region, but also a valuable contribution to the global discourse on moving beyond infrastructure-centric approaches in arid and semi-arid agriculture.

可持续农业依赖于干旱和半干旱地区面临缺水和盐度挑战的有效水资源管理。本研究建立了一个多尺度系统动力学模型来评估沙普尔河流域灌溉政策情景与区域经济平衡之间的相互作用，并对基础设施导向、需求管理和混合情景进行了比较。该模型在区域一级模拟盐度积累和土壤-水动态，同时捕获整个流域的作物产量、农业经济和水利用。计算结果表明，虽然单独进行需求管理（情景4）比前三种以灌溉技术为重点的情景（情景1-3）在净经济利润和水经济价值方面的提高高出10%，并反映了这些仅基于基础设施的政策的反弹效应，但将需求管理和技术改进结合起来的混合情景（情景5）被证明是最有效的。与现状相比，提供最高的经济回报，改善了77%，并显著减少了56%的用水量。这些发现表明，以基础设施为重点的方法的有效性正在下降，同时强调了综合战略的卓越表现。这表明需求管理、灌溉技术和区域经济公平相结合可以产生可持续的结果。它们不仅为研究区域的政策制定者提供了可操作的指导，而且还为在干旱和半干旱农业中超越以基础设施为中心的方法的全球论述做出了宝贵贡献。

In high-income countries, pig production predominantly occurs in conventional indoor systems, but interest in alternative systems is growing. This research applied social science frameworks to understand barriers and facilitators influencing adoption of alternative pig farming practices. Using the COM-B model (Capability-Opportunity-Motivation = Behaviour) and Theoretical Domains Framework, semi-structured interviews and focus groups were conducted with stakeholders from conventional indoor and alternative (free-range and organic) systems. Eighteen interviews (Conventional: n = 9; Alternative: n = 9) and two focus groups (Conventional: n = 5; Alternative: n = 4) explored individual- and industry-level factors affecting the adoption of alternative systems, with pig farming stakeholders. Participants were recruited through purposive sampling, and data were analysed using a deductive Framework approach. Barriers to adoption related to Capability (e.g., shortage of skilled staff, lack of knowledge of alternative farming methods), Motivation (e.g., alternative farming perceived as a hobby), and Opportunity (e.g., power dynamics in the industry, profitability). Facilitators included Capability (e.g., diversification of activities) and Opportunity (e.g., availability of woodlands, support from family and community). The majority of the identified barriers related to lack of opportunity, highlighting the need for a physical and social environment that facilitates the development of alternative pig farming systems. A supportive regulatory and physical environment are essential in progressing alternative pig farming systems.

在高收入国家，生猪生产主要发生在传统的室内系统中，但对替代系统的兴趣正在增长。本研究应用社会科学框架来了解影响采用替代养猪方法的障碍和促进因素。使用COM-B模型（能力-机会-动机=行为）和理论领域框架，对来自传统室内和替代（自由放养和有机）系统的利益相关者进行了半结构化访谈和焦点小组。18个访谈（传统：n = 9；替代：n = 9）和两个焦点小组（传统：n = 5；替代：n = 4）与养猪业利益相关者探讨了影响采用替代系统的个人和行业层面的因素。参与者通过有目的的抽样招募，并使用演绎框架方法分析数据。采用的障碍与能力（例如，缺乏熟练的员工，缺乏对替代农业方法的知识），动机（例如，将替代农业视为一种爱好）和机会（例如，行业中的权力动态，盈利能力）有关。促进因素包括能力（例如，活动的多样化）和机会（例如，林地的可用性，家庭和社区的支持）。所确定的大多数障碍与缺乏机会有关，强调需要一个促进发展替代养猪系统的物质和社会环境。支持性的监管和自然环境对于发展替代性养猪系统至关重要。

Daylighting urban waterways is one form of nature-based solution (NBS) gaining attention amongst cities internationally. Urban daylighting – which involves removing historically buried waterways from underground pipes and bringing them back to the surface – is an intensive form of NBS which can address urban stormwater management, reduce combined-sewage overflow issues, improve riparian habitat, and increase biodiversity. The process of reinserting a waterway in an urban environment makes daylighting an important context for analyzing urban NBS trade-offs and their associated justice implications. We use a typology of trade-offs – rigid, governance, and functional trade-offs – intersected with a socio-ecological justice lens to critically approach and understand the implications of trade-offs in urban daylighting projects. We apply this framework to the contemporary case study of daylighting Tibbetts Brook in The Bronx, New York City. Data was collected through interviews with stakeholders involved in the project, and street interviews, to capture the perceptions of trade-offs related to daylighting. We find governance trade-offs related to the inclusion of local community, and choices between accessibility and ecological functioning. Additionally, we identify functional trade-offs related to daylighting as infrastructural upgrades or maximized ecological benefits, considerations of future use and impacts, and the trade-off between novel and landscaped ecosystems. We examine the differentiated socio-ecological justice dilemmas associated with the trade-offs for diverse groups, including non-human nature. Moreover, we indicate how wider policy and social drivers interconnect and shape the trade-offs in daylighting Tibbetts Brook. Overall, we highlight the socio-ecological benefits that daylighting can provide, as well as the complexity of daylighting in cities and the interconnected infrastructural, social, and ecological factors which create justice dilemmas.

采光城市水道是一种基于自然的解决方案（NBS），受到国际城市的关注。城市采光——包括从地下管道中移除历史上埋在地下的水道，并将其恢复到地面——是一种密集的NBS形式，可以解决城市雨水管理问题，减少综合污水溢出问题，改善河岸栖息地，增加生物多样性。在城市环境中重新插入水道的过程使得采光成为分析城市NBS权衡及其相关司法影响的重要背景。我们使用一种权衡的类型——刚性、治理和功能权衡——与社会生态正义的视角相交叉，批判性地看待和理解城市采光项目中权衡的影响。我们将这一框架应用于纽约市布朗克斯区Tibbetts Brook的采光当代案例研究。通过与项目利益相关者的访谈和街头访谈收集数据，以捕捉与采光相关的权衡的看法。我们发现治理的权衡关系到当地社区的包容，以及可达性和生态功能之间的选择。此外，我们确定了与采光相关的功能权衡，如基础设施升级或最大化生态效益，未来使用和影响的考虑，以及新生态系统和景观生态系统之间的权衡。我们研究了与不同群体（包括非人类）的权衡相关的不同社会生态正义困境。此外，我们指出了更广泛的政策和社会驱动因素是如何相互联系并形成采光Tibbetts Brook的权衡的。总体而言，我们强调了采光可以提供的社会生态效益，以及城市采光的复杂性和相互关联的基础设施、社会和生态因素，这些因素造成了正义困境。

Saline-alkali land is a major global issue in soil degradation, particularly in typical coastal areas like the Yellow River Delta, hindering sustainable development in agriculture and the environment. The management of saline-alkali land requires a comprehensive, long-term, multi-disciplinary approach, with the improvement of saline-alkali land partition being a crucial prerequisite. To propose a comprehensive management plan for coastal saline-alkali land, this study conducted an analysis of 23 ecological and environmental factors, including climate, topography, soil, vegetation, and groundwater. Based on this analysis, the study suggested a zoning and classification approach for governance. Within the first layer of influencing factors, groundwater and soil factors hold the highest weights, followed by climate, while vegetation and topographical influences carry the lowest weights. Among the second layer of influencing factors, weights for the current status of saline-alkaline land, groundwater depth, and groundwater mineralization are relatively higher. According to the zoning model, the saline-alkaline land in the Yellow River Delta is categorized into five zones based on the degree of difficulty: Easy governance area, Mild saline-alkali governance area, Moderate saline-alkali governance area, Severe saline-alkali governance area, and Wetland ecological protection area, respectively accounting for 8.98 %, 12.78 %, 19.49 %, 20.89 %, and 28.56 % of the total coastal saline-alkaline land area in the Yellow River Delta. Corresponding control schemes are proposed for different saline-alkaline land management zones, involving the rational allocation of water conservancy projects, chemical improvement, vegetation restoration and bioremediation, field management, and other measures. This study is intended to provide a scientific reference for coastal saline-alkali land improvement and regional agricultural development.

盐碱地是全球土壤退化的主要问题，特别是在黄河三角洲等典型沿海地区，阻碍了农业和环境的可持续发展。盐碱地治理需要综合、长期、多学科的综合治理，改善盐碱地分区是盐碱地治理的重要前提。为提出滨海盐碱地综合治理方案，本研究对气候、地形、土壤、植被、地下水等23个生态环境因子进行了分析。在此基础上，提出了分区分类治理的思路。在第一层影响因素中，地下水和土壤因素的权重最高，其次是气候，而植被和地形影响的权重最低。第二层影响因素中，盐碱地现状、地下水深度和地下水矿化度权重较高。根据分区模型，将黄河三角洲盐碱地按难易程度划分为易治理区、轻度盐碱地治理区、中度盐碱地治理区、重度盐碱地治理区和湿地生态保护区5个区，分别占黄河三角洲沿海盐碱地总面积的8.98%、12.78%、19.49%、20.89%和28.56%。针对不同盐碱地管理区提出了相应的治理方案，包括合理配置水利工程、化学改良、植被恢复与生物修复、田间管理等措施。本研究旨在为沿海盐碱地改良和区域农业发展提供科学参考。

Amphibian populations face unprecedented declines globally, with pollution identified as a critical threat. We conducted the first screening-level ecological risk assessment of heavy metal (HM) and microplastic (MP) contamination in permanent amphibian breeding marshes across the Hyrcanian Forest biodiversity hotspot of northern Iran, employing Failure Mode and Effects Analysis (FMEA) framework for systematic risk prioritization. Twenty-one breeding marshes spanning elevational gradients from sea level to 2368 m were surveyed for five priority HMs (As, Cd, Cu, Pb, Zn) and MPs during February–May 2024. Results revealed widespread contamination affecting eleven native amphibian species: Cu, Pb, and Zn were detected at 100 %, 90.5 %, and 100 % of stations respectively, with concentrations exceeding established toxicity thresholds for amphibians and/or aquatic invertebrates at most stations. Cd and As showed localized contamination at 14.3 % and 9.5 % of stations. MPs ranged from 0.5 to 5.5 particles L⁻¹, remaining below amphibian toxicity thresholds. The FMEA-based Weighted Risk Priority Number (WRPN) classification identified one station at critical risk, ten at extreme risk, and four at very high risk, with over 80 % of breeding habitats requiring priority management intervention. Contamination sources included mining operations, livestock manure, and long-range atmospheric transport, with unexpected elevation of pollution levels at remote, low-accessibility stations challenging conventional conservation assumptions. This study provides the first comprehensive baseline assessment and quantitative risk prioritization framework for amphibian breeding habitat protection in this globally significant ecoregion, with direct implications for conservation resource allocation and protected area management strategies.

全球两栖动物数量面临前所未有的下降，污染被认为是一个严重的威胁。采用失效模式和效应分析（FMEA）框架对伊朗北部海卡尼亚森林生物多样性热点地区永久性两栖动物繁殖地重金属和微塑料污染进行了首次筛选级生态风险评估。在2024年2月至5月期间，对21个海拔高度从海平面到2368 m的繁殖沼泽进行了5种优先HMs （As, Cd, Cu, Pb, Zn）和MPs的调查。结果显示，11种本地两栖动物受到了广泛的污染：Cu、Pb和Zn分别在100%、90.5%和100%的监测站被检测到，大多数监测站的浓度超过了两栖动物和/或水生无脊椎动物的既定毒性阈值。Cd和As在14.3%和9.5%的站点显示局部污染。MPs范围为0.5至5.5颗粒L−1，仍低于两栖动物毒性阈值。基于fmea的加权风险优先数（WRPN）分类确定了1个站点处于临界风险，10个站点处于极端风险，4个站点处于极高风险，超过80%的繁殖栖息地需要优先管理干预。污染源包括采矿作业、牲畜粪便和远距离大气运输，在偏远、低可达性的站点，污染水平意外上升，挑战了传统的保护假设。本研究为这一全球重要生态区域的两栖动物繁殖栖息地保护提供了第一个全面的基线评估和定量风险优先级框架，对保护资源分配和保护区管理策略具有直接意义。

Homestay tourism in hilly areas has arisen as a sustainable alternative to conventional tourist, prioritizing cultural immersion and the enhancement of local economies. This study assesses the viability of Homestay tourist locations in the Himalayan region, namely the Kalimpong district in India, employing the CRITIC-PROMETHEE-GAIA methodology. The research employs multi-criteria decision-making methodologies to evaluate essential elements including physical accessibility, infrastructure, social dynamics, and environmental sustainability at twelve homestay locations. The research identified 15 indicators affecting tourism potential in Kalimpong, classified into advantageous and disadvantageous attributes. Kolakham obtained the highest score among homestays owing to its exceptional performance in accessibility, accommodation, and resource availability, whereas Rocky Island received the lowest grade. PROMETHEE I and II investigations identified clusters of sites with middling performance, including Kaffergaon, Charkhole, and Ramdhura. Environmental factors (P1–P3) and infrastructure (I1–I6) significantly influenced rankings. Sensitivity and GAIA analysis indicated trade-offs among criteria, with Kolakham exhibiting alignment with important utilities. Poor economic indicators inhibited sites like Rocky Island and Durpindara, underlining the need for focused infrastructure, social services, and sustainable economic development measures. Management strategies should focus on building infrastructure, boosting social entrepreneurship, and expanding market access to support sustainable livelihoods (SDG 8). Enhancing community resilience via social services (SDG 11), mitigating pollution (SDG 13), and conserving natural landscapes (SDG 15) are imperative. Site-specific interventions targeting economic, social, and environmental dimensions can ensure inclusive and balanced growth aligned with SDG goals.

山区的民宿旅游已经成为传统旅游的可持续选择，优先考虑文化沉浸和促进当地经济。本研究采用critical - promehee - gaia方法，评估了喜马拉雅地区（即印度噶伦蓬地区）民宿旅游地点的可行性。该研究采用多标准决策方法来评估12个寄宿家庭的基本要素，包括物理可达性、基础设施、社会动态和环境可持续性。研究确定了影响噶伦堡旅游潜力的15个指标，并将其分为有利属性和不利属性。Kolakham由于在可达性、住宿和资源可用性方面的出色表现，在寄宿家庭中获得了最高分，而Rocky Island则获得了最低分。PROMETHEE I和II的调查确定了表现中等的地点群，包括Kaffergaon、Charkhole和Ramdhura。环境因素（P1-P3）和基础设施（I1-I6）对排名影响显著。敏感性和GAIA分析表明了标准之间的权衡，Kolakham表现出与重要公用事业的一致性。糟糕的经济指标抑制了像Rocky Island和Durpindara这样的地方，强调了重点基础设施、社会服务和可持续经济发展措施的必要性。管理战略应侧重于建设基础设施、促进社会创业和扩大市场准入，以支持可持续生计（可持续发展目标8）。通过社会服务（可持续发展目标11）、减轻污染（可持续发展目标13）和保护自然景观（可持续发展目标15）增强社区复原力势在必行。针对经济、社会和环境层面的具体地点干预措施可以确保与可持续发展目标相一致的包容性和平衡增长。

Greenhouse gas emission abatement is a primary objective of the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change (UNFCCC) under the Kyoto Protocol. In this study, three criteria were developed and ascribed to CDM projects under sectoral scope 13, “waste handling and disposal”: 1) project performance; 2) specific costs for issued certified emission reductions (CERs); and 3) transition status to the Paris Agreement Crediting Mechanism (PACM) or a voluntary carbon offsetting program. Using the criteria and a success threshold, an aggregate scoring system was devised to rate the overarching “success” of each individual project. Finally, the projects were grouped by geographic subregion, project subtype, and size classification to observe success rate differences.

Of 280 projects evaluated, only 114 were assessed as being successful under this model (40.7 %). Projects in “Latin America and the Caribbean” were more than 1.5 times more likely to be evaluated as successful as projects in “Southeast Asia” and “Mainland Asia”. Projects classified as “large” were 1.8 times more likely to be evaluated as successful compared to projects classified as “small”. Projects managing “manure”, “landfill power”, and “landfill flaring” were more likely to be evaluated as successful as “waste water” projects.

The evaluation also showed that amongst the chosen criteria, cost-effectiveness is the least critical criterion for the success and longevity of the CDM projects. The developed novel scoring method provides a useful tool to assess the general project performance of CDM projects and could also be applied to other sectoral scopes.

减少温室气体排放是《京都议定书》下的《联合国气候变化框架公约》（UNFCCC）清洁发展机制（CDM）的首要目标。在这项研究中，在行业范围13“废物处理和处置”下，为清洁发展机制项目制定了三个标准：1)项目绩效；2)核发经认证的减排量（CERs）的具体成本；3)向《巴黎协定》信用机制（PACM）或自愿碳抵消计划过渡。使用标准和成功阈值，设计了一个综合评分系统来评估每个单独项目的总体“成功”。最后，根据地理分区、项目子类型和规模分类对项目进行分组，观察成功率差异。在评估的280个项目中，只有114个在该模式下被评估为成功（40.7%）。“拉丁美洲和加勒比”项目获得成功评价的可能性是“东南亚”和“亚洲大陆”项目的1.5倍以上。被归类为“大型”的项目被评估为成功的可能性是被归类为“小型”项目的1.8倍。管理“粪便”、“垃圾填埋发电”和“垃圾填埋燃烧”的项目更有可能被评估为与“废水”项目一样成功。评估还表明，在选择的标准中，成本效益是清洁发展机制项目成功和寿命的最不关键的标准。所开发的新的评分方法为评估清洁发展机制项目的总体项目绩效提供了一个有用的工具，也可应用于其他部门范围。
