For One Planet City Challenge Participants
Getting started, going deeper

Thank you for joining our One Planet City Challenge. As a participant we provide you with a wealth of tools and resources if your city is ready to commit to the challenge of keeping global temperature rise at a maximum of 1.5 °C.  

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 recognition, and contribute to the cooperative effort for science-based climate action. 

Below you find some important dates. In this round we also welcome you to a webinar series where we will launch new guidelines and resources on a variety of topics. We further offer you to the opportunity to join a cutting-edge software platform where you can craft your climate action plan supported by both peers and experts.  

Our aim is to boost your capacity to the respond to the climate crisis.
