For One Planet City Challenge Participants

Getting started, going deeper

WWF provides a wealth of tools and resources for cities ready to commit to the challenge of keeping global temperature rise to under 1.5C. 

We think the benefits are big: cities join an exceptional group of global actors, enjoy expert feedback of commitments and actions, receive increased local and international awareness, and contribute to the cooperative effort for science-based climate action.
