Introduction

Acknowledging the exponential growth and global dimension of climate litigation, this introductory piece to this Special Section starts by situating this phenomenon in the context of the scholarly debate on polycentric and multi-level climate governance. It highlights both the strategic use of climate litigation as a tool to establish responsibilities and push for a more ambitious mitigation and adaptation agenda, but also as an opportunity to better understand the role of courts in public policy governance. The second part of the article then proceeds to discuss the main findings arising from the various contributions grouped in this section, and concludes by arguing that further research is needed in order to properly understand the role and contribution of climate change litigation to transnational climate governance.
