Abstract

Carbon emission allowance (CEA) allocation mechanisms balancing equity, efficiency, and sustainability principles are central to effective carbon emission trading markets. When national or regional carbon emission trading markets extend to the shipping industry, allocating suitable volumes of CEAs to different shipping companies plays a fundamental role in system effectiveness. The allocation practice of Shanghai Pilot Carbon Emissions Trading based on the single allocation rule of historical carbon intensity has shown limitations in balancing multiple allocation objectives. This study aims to address this limitation by proposing a new CEA allocation mechanism that incorporates multiple indicators and seeks to balance the principles of fairness, efficiency and sustainability. This mechanism consists of a composite-index method for initial CEA allocation and a zero-sum gains data envelopment analysis (ZSG-DEA) model with carbon efficiency optimization to adjust CEA allocation to shipping companies. The case study focusing on liner shipping companies in China suggests that the proposed allocation mechanism can encourage large companies with high-carbon emissions to bear more reduction pressure while supporting companies with superior carbon efficiency to receive proportionally higher allowances. The methodology demonstrates potential for adaptation to other shipping segments and can support governments in incorporating maritime shipping sectors into carbon emission trading systems while facilitating international coordination.

中国班轮运输企业碳排放限额多指标分配：基于复合指标和零和收益DEA的综合方法

平衡公平、效率和可持续性原则的碳排放配额分配机制是有效的碳排放交易市场的核心。当国家或区域碳排放交易市场扩展到航运业时，为不同的航运公司分配适当数量的cea对系统有效性起着根本性的作用。基于历史碳强度单一分配规则的上海碳排放权交易试点分配实践在平衡多个分配目标方面存在局限性。本研究旨在通过提出一种新的经济效益分配机制来解决这一限制，该机制包含多个指标，并寻求平衡公平、效率和可持续性原则。该机制包括初始CEA配置的复合指数法和零和收益数据包络分析（ZSG-DEA）模型，并结合碳效率优化来调整航运公司的CEA配置。以中国班轮公司为研究对象的案例研究表明，建议的配额机制可以鼓励高碳排放的大公司承担更大的减排压力，同时支持碳效率较高的公司按比例获得更高的配额。该方法显示了适用于其他航运部门的潜力，并可支持各国政府将海运部门纳入碳排放交易体系，同时促进国际协调。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
