We are mayors working together to demonstrate leadership on climate change.

Building a better future with a clear vision for protecting the environment.

Founded in 2014, Climate Mayors is a bipartisan network of nearly 350 mayors who demonstrate climate leadership through meaningful actions in their communities. Representing 46 states and nearly 60 million Americans, Climate Mayors reflects U.S. cities’ commitment to climate progress.

In addition to local climate leadership, Climate Mayors build political will for federal and global climate action. Hundreds of members have signed the Climate Mayors letters committing to the Paris Agreement and calling on Congress to invest in a green and equitable economic recovery.
