摘要 2016 年生效的《巴黎协定》设定了雄心勃勃的气候变化减缓目标，即将全球气温上升限制在 2°C 以下，最好是 1.5°C。这对剩余的全球温室气体排放预算造成了严重限制。虽然国际航运也是人为温室气体排放（尤其是二氧化碳）的一个贡献者，但它并未包含在《巴黎协定》中。本文讨论了二十一世纪全球二氧化碳预算的一部分如何分配给国际航运，并利用一系列未来贸易情景，探讨了航运二氧化碳强度的必要削减。结果表明，在各种假设下，必须紧急利用现有的短期效率杠杆，以实现与其他经济部门的要求相称的减排目标，并要求早在本世纪中叶之前就要求国际航运几乎完全脱碳。主要政策见解 监管行动是确保国际航运业长期可持续性的关键。航运业要根据《巴黎协定》实现减排，就需要实现几乎完全脱碳。短期内，立即、快速利用现有的缓解措施至关重要。过渡过程中的任何延误都会增加资产搁浅的风险，或降低实现《巴黎协定》温度承诺的机会。
ABSTRACT The Paris Agreement, which entered into force in 2016, sets the ambitious climate change mitigation goal of limiting the global temperature increase to below 2°C and ideally 1.5°C. This puts a severe constraint on the remaining global GHG emissions budget. While international shipping is also a contributor to anthropogenic GHG emissions, and CO2 in particular, it is not included in the Paris Agreement. This article discusses how a share of a global CO2 budget over the twenty-first century could be apportioned to international shipping, and, using a range of future trade scenarios, explores the requisite cuts to the CO2 intensity of shipping. The results demonstrate that, under a wide range of assumptions, existing short-term levers of efficiency must be urgently exploited to achieve mitigation commensurate with that required from the rest of the economy, with virtually full decarbonization of international shipping required as early as before mid-century. Key policy insights Regulatory action is key to ensuring the international shipping sector’s long-term sustainability. For the shipping industry to deliver mitigation in line with the Paris Agreement, virtually full decarbonization needs to be achieved. In the near term, immediate and rapid exploitation of available mitigation measures is of critical importance. Any delay in the transition will increase the risk of stranded assets, or diminish the chances of meeting the Paris Agreement's temperature commitments.
