The American Cities Climate Challenge is an opportunity for 25 cities to significantly deepen and accelerate their efforts to tackle climate change and promote a sustainable future for their residents. 25 cities have been accepted into a two-year acceleration program with powerful resources and access to cutting-edge support to help them meet – or beat – their near-term carbon reduction goals. These resources include a philanthropy-funded team member to facilitate the development and passage of high impact policies, training for senior leadership to assist with implementation of their proposed climate plans, and citizen engagement support to maximize community buy-in.
