Abstract

Recent regulatory changes have impacted the European Union (EU) maritime sector. This study evaluates the effect of carbon dioxide (CO₂) emissions on the production frontier and Technical Efficiency (TE) of cargo handling services in Spain's 23 largest ports. Using the Material Balance Theorem, we justify the inclusion of CO₂ in a stochastic frontier model. Results show that accounting for emissions increases the weight of quasi-fixed inputs and reduces average inefficiency. These findings suggest that the new EU Maritime regulation (FuelEU and ETS) could help to internalize environmental externalities in port operations.

西班牙港口效率分析内部化二氧化碳排放：具有政策见解的随机前沿方法

最近的法规变化影响了欧盟（EU）海事部门。本研究评估了二氧化碳（CO2）排放对西班牙23个最大港口货物处理服务的生产前沿和技术效率（TE）的影响。使用物质平衡定理，我们证明了在随机前沿模型中包含二氧化碳。结果表明，考虑排放增加了准固定投入的权重，降低了平均效率低下。这些发现表明，新的欧盟海事法规（FuelEU和ETS）可以帮助将港口运营中的环境外部性内部化。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
