This book takes an innovative approach to studying international climate governance by providing a critical analysis of climate leadership, pioneership and followership across the globe.The volume assesses the interactions between climate leaders, pioneers and followers, across multilevel and/or polycentric climate governance contexts. Examining the state and sub-state levels in both the Global South and Global North, as well as regional, supranational EU and international climate governance levels, the authors explore 16 countries across Asia, Australasia, Europe, and Central and North America, plus the European Union. Each chapter employs a comprehensive and consistent framework for analyzing leadership and pioneership, as well as followership. The findings provide new insights into the strategies and actions of sub-state, state-level, and supranational leaders and pioneers.This book will be of key interest to scholars, students and practitioners in environmental politics and climate change governance, as well as those interested in political elites, EU studies and, more broadly, comparative politics and international relations.The Open Access version of this book, available at www.taylorfrancis.com, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives (CC-BY-NC-ND) 4.0 license.
