WHere We Started

In August 2016, we inaugurated this remarkable gathering, the first of its kind, the Climate Leadership Summit. Our founding mayors, Jim Brainard and Joe Stahura, along with Earth Charter Indiana, convened mayors, their delegations, experts, and advocates from across the state for a day of intensive learning. The purpose was simple: to inspire action to create climate resilient communities across the Hoosier State.
