Abstract
This Chapter explores private international law (PIL) issues arising in transnational climate change cases based on private law. It adopts a broad comparative perspective, going beyond European Union PIL to also consider other legal traditions, though it acknowledges that most relevant litigation has occurred in Continental Europe. The analysis centres on how PIL facilitates or restricts access to remedy by shaping the questions of jurisdiction, applicable law, and recognition and enforcement of foreign judgments. While academic debates in this field are lively, actual climate change litigation raising PIL issues remainslimited. This Chapter aims to provide conceptual insights into the interaction between PIL and climate change, contributing to broader debates on sustainability, global governance, and the regulatory potential of the field.
