Carbon leakage – the increase of greenhouse gas emissions in foreign jurisdictions following the introduction of domestic or regional climate mitigation measures – raises key questions in the climate change debate. This includes whether carbon leakage constitutes a threat to the environmental integrity of climate policies and, if so, how this could be mitigated. Through the use of four hypothetical models of international climate change regime, this article argues that international climate change law is a key factor in answering this two-part question. Firstly, the article demonstrates that the architecture of international climate change law affects whether carbon leakage can be considered as undermining the mitigation objective of climate policies. Secondly, it draws attention to the interaction – and potential tension – between carbon leakage prevention measures and international climate change law.

碳泄漏与国际气候变化法

碳泄漏——在引入国内或区域气候缓解措施后外国司法管辖区温室气体排放量的增加——在气候变化辩论中提出了关键问题。这包括碳泄漏是否对气候政策的环境完整性构成威胁，如果是，如何减轻这种威胁。本文通过使用国际气候变化制度的四种假设模型，认为国际气候变化法是回答这个由两部分组成的问题的关键因素。首先，文章表明，国际气候变化法的架构会影响碳泄漏是否可以被视为破坏气候政策的缓解目标。其次，它提请人们注意碳泄漏预防措施与国际气候变化法之间的相互作用和潜在的紧张关系。
