Reducing greenhouse gas emissions from maritime transport is an urgent topic. Some regional emissions trading systems (ETSs), buoyed by the globalized market-based measures (MBMs) plan of the International maritime organization, have initially assessed the feasibility of including maritime emissions under compliance obligations. However, including maritime emissions (which are interjurisdictional) in the existing ETSs is controversial, and globalized maritime MBMs remain elusive. Therefore, this study designed a joint bilateral maritime carbon market (BMCM) model based on the European ETS (EU-ETS) and Quebec ETS (QC-ETS). The carbon costs, speed optimization, and marginal abatement costs of three container routes under BMCM were analyzed. The results show that this Euro-American linkage achieves adequate emission coverage on specific routes and generates acceptable carbon costs for charterers. This study yields a positive result for the equal division of ETSs' exercising competence in cross-regional maritime transport and provides evidence for sector-specific ETS links based on quantitative analysis.
减少海运温室气体排放是一个紧迫的议题。一些地区性排放交易体系（ETS）在国际海事组织（IMO）的全球化市场措施（MBMs）计划的推动下，初步评估了将海运排放纳入合规义务的可行性。然而，将具有跨国界性质的海运排放纳入现有 ETS 存在争议，而全球化的海事 MBMs 仍然难以实现。因此，本研究基于欧洲排放交易体系（EU-ETS）和魁北克排放交易体系（QC-ETS），设计了一个联合双边海运碳市场（BMCM）模型。分析了在 BMCM 下三条集装箱航线的碳成本、速度优化和边际减排成本。结果表明，这种欧美连接在特定航线上实现了充分的排放覆盖，并为租船人带来了可接受的碳成本。本研究在跨区域海运中平等划分 ETS 行使管辖权方面取得了积极成果，并为基于定量分析的特定部门 ETS 连接提供了证据。
