《哥本哈根雅阁》（和《坎昆协定》）要求国际社会“将全球气温上升幅度控制在2°C以下，并采取符合科学和公平的行动实现这一目标”。本文探讨了这些承诺对航运业的影响。它概述了气候变化科学如何在全球范围内对该行业的排放进行严格限制，而公平方面则进一步收紧了附件1国家的行业排放空间。详细说明了拟议的全球范围措施的缓解潜力，并讨论了非附件1和附件1之间的排放分配。基于累积排放的科学框架，这篇文章得出结论，如果该行业不想推翻“将全球气温上升控制在2°C以下”的更广泛努力，那么除了立即“Scharnow转向”之外，没有任何必要。
The Copenhagen Accord (and Cancun Agreement) commits the international community to “hold the increase in global temperature below 2°C, and take action to meet this objective consistent with science and on the basis of equity.” This article explores the implications of these commitments for the shipping sector. It outlines how the science of climate change places stringent constraints on the sector’s emissions at the global level while the equity dimension tightens still further the industry’s emissions space for the Annex 1 nations. The mitigation potential of proposed global-scale measures are detailed and the apportionment of emissions between non-Annex 1 and Annex 1 discussed. Building on the scientific framing of cumulative emissions, the article concludes that nothing short of an immediate ‘Scharnow turn’ is necessary if the industry is not to capsize wider efforts to “hold the increase in global temperature below 2°C”.
