Achieving universal access to safe sanitation is a challenge that requires the integration of public policies, investment, technology, and efficient sewage waste treatment. This study examines sewage waste management in Brazil from a sustainable development perspective, assessing the availability of resources, actions, treatment types, disposal methods, treatment efficiency, and potential reuse opportunities. Historical data from 5570 Brazilian municipalities were compiled from key national sanitation databases. The analysis combines descriptive statistics, exploratory factor analysis, and qualitative assessments of the Sustainable Development Goal (SDG) 6 targets. The findings reveal that Brazilian sewage programs primarily emphasize population coverage while neglecting technical and qualitative aspects of sewage treatment. Water potability remains below SDG target 6.1, and if current investment patterns persist, Brazil will not meet target 6.2 by 2030, leaving only 42 % of the population with access to sewage services. Analysis of target 6.a highlights issues with insufficient local policies and limited financial investment. The development of the Sewage Treatment Index (STI) enabled a comprehensive assessment of treatment efficiency across all 5570 municipalities, highlighting areas for improvement and opportunities for sustainable practices. The results showed that only 33 % of municipalities met satisfactory sewage treatment efficiency (target 6.3). Although still in its early stages, incipient efforts toward sustainable sewage management are emerging through the regulated reuse of sewage waste in 1 % of municipalities, offering promising environmental, social, and economic potential benefits. However, the lack of regular census and sanitation survey data hinders transparent monitoring of progress toward SDG goals and national requirements. These findings raise questions about the accuracy of SDG 6 monitoring globally, suggesting that other countries may also be further from achieving the targets than current reports suggest.

实现普遍获得安全卫生设施是一项挑战，需要将公共政策、投资、技术和有效的污水处理结合起来。本研究从可持续发展的角度考察了巴西的污水废物管理，评估了资源的可用性、行动、处理类型、处置方法、处理效率和潜在的再利用机会。来自5570个巴西城市的历史数据是从主要的国家卫生数据库中汇编的。该分析结合了描述性统计、探索性因素分析和可持续发展目标6具体目标的定性评估。研究结果表明，巴西的污水处理项目主要强调人口覆盖率，而忽视了污水处理的技术和质量方面。饮用水仍然低于可持续发展目标6.1，如果目前的投资模式持续下去，到2030年，巴西将无法实现目标6.2，届时只有42%的人口能够获得污水处理服务。6.目标分析A突出了地方政策不足、财政投入有限的问题。污水处理指数（STI）的开发能够对所有5570个城市的处理效率进行全面评估，突出了需要改进的领域和可持续实践的机会。结果表明，只有33%的城市达到了令人满意的污水处理效率（目标6.3）。尽管仍处于早期阶段，但通过1%的城市对污水废物的规范再利用，可持续污水管理的初步努力正在出现，提供了有希望的环境，社会和经济潜在效益。然而，缺乏定期人口普查和卫生调查数据阻碍了对可持续发展目标和国家要求进展情况的透明监测。这些发现对全球可持续发展目标6监测的准确性提出了质疑，表明其他国家也可能比目前报告所显示的距离实现目标更远。

The interfacing with digital transformation and smart grid requirements necessitates a standardized Enterprise Architecture (EA) in Distribution System Operators (DSOs). Based on a review of process models from 39 Iranian DSOs, this study examines two frameworks: the general-domain American Productivity and Quality Center (APQC) and the domain-specific IEC 61968–1:2020, to assess their adaptation across the business, information, software, and technology layers of EA. The findings show that while APQC provides the classification of business processes, it does not model data flows, software systems, and technologies, thus requiring extensive customization for adaptation in DSOs. In contrast, IEC, which presents a software architecture for DSOs, offers a precise model for the flow of data and tasks, facilitating minimal customization for implementation.

数字化转型和智能电网需求的对接要求配电系统运营商（dso）必须采用标准化的企业架构（EA）。基于对39个伊朗dso过程模型的回顾，本研究考察了两个框架：通用领域的美国生产力和质量中心（APQC）和特定领域的IEC 61968-1:2020，以评估它们在EA的业务、信息、软件和技术层上的适应性。研究结果表明，虽然APQC提供了业务流程的分类，但它没有为数据流、软件系统和技术建模，因此需要在dso中进行广泛的定制以适应。相比之下，IEC为dso提供了一个软件架构，为数据和任务流提供了一个精确的模型，为实现提供了最小的定制。

This study examines the drivers of community engagement in sustainable energy transitions in Northern Ghana, with a focus on the concept of energy citizenship. Through a survey of 678 residents across selected rural communities, the study examines how awareness, motivation, and perceived benefits influence active participation in renewable energy initiatives, employing the Structural Equation Modeling approach. Key constructs were validated through Confirmatory Factor Analysis, and the relationships were tested using path analysis. Results indicate that community members are motivated by affordability, local economic benefits, and a sense of ownership over energy systems. However, policy awareness showed limited influence on engagement, and infrastructural gaps persist. The study recommends enhanced local engagement strategies and targeted education campaigns to strengthen energy citizenship and promote inclusive energy governance.

本研究考察了加纳北部社区参与可持续能源转型的驱动因素，重点关注能源公民的概念。通过对选定农村社区的678名居民的调查，本研究采用结构方程建模方法，考察了意识、动机和感知利益如何影响可再生能源倡议的积极参与。通过验证性因子分析对关键构念进行验证，并使用通径分析对关系进行检验。结果表明，社区成员的动机是可负担性、当地经济效益和对能源系统的主人翁意识。然而，政策意识对参与的影响有限，基础设施差距仍然存在。该研究建议加强地方参与战略和有针对性的教育活动，以加强能源公民意识，促进包容性能源治理。

During the extreme heatwaves of 2016, the South Korean government temporarily modified the increasing-block rate (IBR) pricing structure by expanding the usage thresholds for each pricing tier to reduce the burden of electricity bills. This study examines the effects of this adjustment on residential electricity consumption. Using a quasi-experimental approach with household survey data, the analysis reveals that households increase their electricity consumption after receiving bills with reduced charges, undermining the energy conservation goals of the original IBR structure. Specifically, middle-income households show a statistically significant increase in electricity usage, whereas the other groups exhibit negligible changes. The summer IBR relaxation primarily benefits middle-income households, leaving low-income households largely unaffected in terms of affordability. These findings highlight the policy challenges of trying to target and protect vulnerable households during periods of extreme heat.

在2016年的极端热浪中，韩国政府通过扩大每个定价层的使用门槛，临时修改了IBR定价结构，以减轻电费负担。本研究考察了这一调整对居民用电量的影响。通过对住户调查数据的准实验方法分析，发现住户在收到费用降低的账单后增加了他们的用电量，破坏了原始IBR结构的节能目标。具体来说，中等收入家庭的用电量在统计上显著增加，而其他群体的变化可以忽略不计。夏季IBR的放松主要使中等收入家庭受益，而低收入家庭在负担能力方面基本不受影响。这些发现突出了在极端高温期间试图瞄准和保护脆弱家庭的政策挑战。

Colombia's Just Energy Transition faces significant hurdles, including renewable energy deployment delays, social conflicts, economic constraints, and escalating electricity demand. During periods of low hydropower availability, coal remains a critical energy source, complicating efforts to phase it out. This study employs a system dynamics model to evaluate three distinct policies—phased coal reduction, complete phase-out, and a higher emissions tax—and their effectiveness under various future scenarios. Our results reveal that external factors such as fuel prices, demand shifts, and hydrological conditions significantly influence the feasibility of these policies. While a gradual transition may not drastically alter the long-term trajectory, it can effectively curb future coal dependence. The findings underscore that effective planning is crucial for mitigating potential price spikes and adverse social impacts. This research offers policymakers actionable strategies to navigate Colombia's complex energy transition towards a secure, sustainable, and affordable electricity generation mix.

哥伦比亚的公平能源转型面临重大障碍，包括可再生能源部署延迟、社会冲突、经济制约和不断上升的电力需求。在水电供应不足的时期，煤炭仍然是一种重要的能源，这使逐步淘汰煤炭的努力复杂化。本研究采用系统动力学模型来评估三种不同的政策——分阶段减少煤炭、完全淘汰煤炭和提高排放税——以及它们在不同未来情景下的有效性。研究结果表明，燃料价格、需求变化和水文条件等外部因素显著影响了这些政策的可行性。虽然逐步过渡可能不会彻底改变长期轨迹，但它可以有效地遏制未来对煤炭的依赖。研究结果强调，有效的规划对于减轻潜在的价格飙升和不利的社会影响至关重要。这项研究为政策制定者提供了可行的策略，以引导哥伦比亚复杂的能源转型向安全、可持续和负担得起的发电组合发展。

Traditional bioenergy, used in many African nations, is not recognized as a renewable or sustainable energy source. Some countries on the continent are officially leading the way in achieving SDG7, thanks to this type of energy. As of 2020, some African nations had a relatively high proportion of renewable energy (RE) in their primary energy supply, contributing to their enhanced energy self-sufficiency. In this study, 15 low- and lower-middle-income African countries are selected, and the elements that statistically significantly affect high shares of RE supply from 2000 to 2022 are scrutinized. For this purpose, second-generation panel data methods, CS-ARDL, are used to assess the effects of sustainability, economic growth, and energy equity indicators on the share of renewables in primary energy supply. The study shows that in the short term, RE supply is significantly but adversely affected by the total primary energy use. Energy intensity and access to renewable fuels contribute to an increased supply of RE. Moreover, RE supply experiences a strong and favourable influence from both economic expansion and lower interest rates. This study contributes to the body of knowledge on renewable-based energy systems in African countries by underlining the impact of interest rates and other factors that influence RE share in the entire primary energy supply, going beyond the power sector. The findings could serve as an evidence base for decision-makers in drafting evidence-based investment, sustainable development, and development assistance strategies.

许多非洲国家使用的传统生物能源不被认为是可再生或可持续的能源。由于这种能源，非洲大陆上的一些国家正式在实现可持续发展七国集团方面处于领先地位。截至2020年，一些非洲国家的可再生能源在一次能源供应中所占比例较高，有助于提高能源自给率。在本研究中，选择了15个低收入和中低收入非洲国家，并对2000年至2022年在统计上显著影响可再生能源供应高份额的因素进行了仔细研究。为此，使用第二代面板数据方法CS-ARDL来评估可持续性、经济增长和能源公平指标对可再生能源在一次能源供应中所占份额的影响。研究表明，在短期内，可再生能源供应受到一次能源使用总量的显著不利影响。能源强度和可再生燃料的获取有助于可再生能源供应的增加。此外，可再生能源供应受到经济扩张和较低利率的强烈和有利影响。这项研究通过强调利率和其他影响可再生能源在整个初级能源供应中所占份额的因素的影响，对非洲国家可再生能源系统的知识体系作出了贡献，超出了电力部门。研究结果可作为决策者制定循证投资、可持续发展和发展援助战略的证据基础。

Mandatory Domestic Waste Classification (MDWC) is an effective strategy for alleviating the urban waste crisis. This paper integrates public online petition text data and urban panel data, employing the synthetic control method to evaluate the impact of MDWC policy on government response to Public Complaints about Solid Waste Sorting (PCSWS) from the perspective of policy pressure. By analyzing data from the Mayor's Message Boards of 11 Chinese cities between 2015 and 2022, the research results indicate that the MDWC policy significantly improved both the speed and quality of government responses to PCSWS. However, the sustainability of these effects has diminished over time. Assessing the impact of the MDWC policy on government responses to PCSWS not only enhances government responsiveness but also promotes positive interaction between the government and the public. Furthermore, enhancing governmental environmental regulation and governance capacity can play a positive role. Therefore, the government should maintain policy oversight following the policy implementation by continuously mobilizing various resources and regulatory measures to ensure policy sustainability and stability. This paper provides an empirical basis for improving the long-term regulatory mechanism of public waste sorting. It holds a significant reference value for promoting the scientific evaluation of government response capabilities in urban environmental governance.

强制性生活垃圾分类是缓解城市垃圾危机的有效策略。本文结合公众网上信访文本数据和城市面板数据，采用综合控制方法，从政策压力的角度，评估了垃圾分类处理政策对政府回应固体废物分类投诉的影响。通过分析2015年至2022年中国11个城市的市长留言板数据，研究结果表明，MDWC政策显著提高了政府对PCSWS的响应速度和质量。然而，随着时间的推移，这些影响的可持续性已经减弱。评估委员会的政策对政府应对公共服务社会的影响，不仅能提高政府的应对能力，还能促进政府与公众的良性互动。此外，提高政府环境监管和治理能力可以发挥积极作用。因此，政府应在政策实施后保持政策监督，不断调动各种资源和监管措施，确保政策的可持续性和稳定性。本文为完善公共垃圾分类的长效监管机制提供了实证依据。对于促进城市环境治理中政府应对能力的科学评价具有重要的参考价值。

Amid Indonesia's push to expand renewable energy, this study evaluates the long-term impact of the depletion premium—a revenue-neutral policy that reallocates 25 % of fossil fuel tax revenue to support solar photovoltaic (PV) development—using 15 years of national data. An optimization model, calibrated with World Bank (2017) parameters, compares two strategies: raising subsidies and improving PV efficiency. Results indicate that a 5 % subsidy increase enhances capital efficiency and solar generation but dampens new investment. By contrast, a 5 % improvement in PV efficiency delivers greater overall economic returns. The findings suggest that combining targeted early subsidies with efficiency improvements can accelerate solar expansion, reduce dependence on fossil fuels, and advance Indonesia's renewable energy goals while maintaining fiscal sustainability.

在印尼推动扩大可再生能源的过程中，本研究利用15年的国家数据评估了枯竭补贴的长期影响。枯竭补贴是一项收入中性政策，将25%的化石燃料税收收入重新分配给太阳能光伏（PV）的发展。使用世界银行（2017）的参数校准的优化模型比较了两种策略：提高补贴和提高光伏发电效率。结果表明，5%的补贴增加提高了资本效率和太阳能发电，但抑制了新的投资。相比之下，光伏发电效率提高5%就能带来更大的整体经济回报。研究结果表明，将有针对性的早期补贴与提高效率相结合，可以加速太阳能的发展，减少对化石燃料的依赖，并在保持财政可持续性的同时推进印尼的可再生能源目标。

The potential benefits of retail electricity market liberalization have been the subject of intense debate. Taking stock of both the academic work and the current state of retail markets in Europe, this article seeks to assess whether opening competition has led to an increase in consumer welfare. We conclude that the benefits of retail competition remain unclear and controversial while the costs are substantial. In light of these findings and given the growing importance of decarbonization and inequality issues, policy-driven changes should be considered to build stable regulatory frameworks that prioritize consumer protection over unfettered competition.

零售电力市场自由化的潜在好处一直是激烈辩论的主题。通过对学术工作和欧洲零售市场现状的评估，本文试图评估开放竞争是否导致了消费者福利的增加。我们得出的结论是，零售竞争的好处仍然不清楚和有争议，而成本是巨大的。鉴于这些发现，并考虑到脱碳和不平等问题日益重要，应考虑政策驱动的变革，以建立稳定的监管框架，优先考虑保护消费者，而不是不受约束的竞争。

Impact of ESG performance on the cost of capital in the energy, utilities, and basic materials sectors ESG绩效对能源、公用事业和基础材料行业资本成本的影响

This paper explores the presence of an environmental, social, and governance (ESG) premium for firms operating in the energy, utilities, and basic materials sectors. Specifically, we examine the influence of ESG performance on firms’ cost of capital in both debt and equity markets. We apply a measure of the ex ante implied cost of equity and the cost of debt to a global sample of over 24,000 firm-year observations spanning the period from 2010 to 2021. We also investigate the financial impact of each component of the aggregated ESG score. We employ a pooled ordinary least squares with robust standard errors, controlling for firm-specific and macroeconomic factors.

Contrary to the prevailing view in recent literature, our results indicate no evidence supporting an ESG premium for energy, utilities, and basic materials firms. However, we find an inverse relationship between environmental performance and the cost of capital. This finding supports the existence of a “green premium,” which can be attributed to green investor preferences and sustainable operations, reducing regulatory and other environmental risks. In contrast, the social score is positively related to the cost of debt, suggesting that lenders view investments in social efforts as risk-enhancing or a waste of resources. We argue that the aggregated ESG score is too broad, but its components adequately capture investors’ risk-return preferences. Firms can benefit from reduced financing costs by improving their environmental efforts, although social investments may result in higher borrowing costs.

本文探讨了在能源、公用事业和基础材料行业经营的公司存在的环境、社会和治理（ESG）溢价。具体而言，我们考察了ESG绩效对债务市场和股票市场公司资本成本的影响。我们对2010年至2021年期间超过24,000家公司的全球样本进行了事前隐含股权成本和债务成本的测量。我们还研究了ESG总得分的每个组成部分的财务影响。我们采用具有稳健标准误差的汇总普通最小二乘，控制了企业特定因素和宏观经济因素。与最近文献中的流行观点相反，我们的研究结果表明，没有证据支持能源、公用事业和基础材料公司的ESG溢价。然而，我们发现环境绩效与资本成本之间呈反比关系。这一发现支持了“绿色溢价”的存在，这可以归因于绿色投资者的偏好和可持续运营，减少了监管和其他环境风险。相反，社会得分与债务成本呈正相关，这表明贷款人认为社会努力的投资增加了风险或浪费了资源。我们认为，综合ESG评分过于宽泛，但其组成部分充分反映了投资者的风险回报偏好。虽然社会投资可能导致借贷成本上升，但企业可以通过改善其环境努力来降低融资成本。

Specifically, we examine the influence of ESG performance on firms’ cost of capital in both debt and equity markets. We apply a measure of the ex ante implied cost of equity and the cost of debt to a global sample of over 24,000 firm-year observations spanning the period from 2010 to 2021. We also investigate the financial impact of each component of the aggregated ESG score. We employ a pooled ordinary least squares with robust standard errors, controlling for firm-specific and macroeconomic factors.</div><div>Contrary to the prevailing view in recent literature, our results indicate no evidence supporting an ESG premium for energy, utilities, and basic materials firms. However, we find an inverse relationship between environmental performance and the cost of capital. This finding supports the existence of a “green premium,” which can be attributed to green investor preferences and sustainable operations, reducing regulatory and other environmental risks. In contrast, the social score is positively related to the cost of debt, suggesting that lenders view investments in social efforts as risk-enhancing or a waste of resources. We argue that the aggregated ESG score is too broad, but its components adequately capture investors’ risk-return preferences. Firms can benefit from reduced financing costs by improving their environmental efforts, although social investments may result in higher borrowing costs.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"97 ","pages":"Article 102016"},"PeriodicalIF":4.4,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
