Key Message
Cities are becoming indispensable players in climate governance, both as implementers of local climate policies and as political actors capable of generating substantial upward pressure on national governments. To maximize their impact, cities must harness their unique advantages, such as proximity to climate impacts and ability to mobilize local political will. By participating in transnational networks, cities can amplify their efforts, share best practices, and drive national and global climate commitments. These actions, while not a complete solution, represent a crucial component of the broader strategy needed to address climate change effectively and sustainably.
