The Bloomgberg Philanthropies American Cities Climate Challenge is a major new effort to expedite progress in reducing greenhouse gas (GHG) emissions while growing local economies during a time of inaction from the federal government. Bloomberg Philanthropies will select the 20 mayors demonstrating the strongest leadership and commitment to move America forward on delivering the goals of the Paris Agreement – a 26% reduction in emissions from 2005 levels. Selected cities will participate in a two-year program designed to significantly deepen the impact of their efforts to tackle climate change. The $70 million investment includes funding from a philanthropic partner and additional charitable partners may join the effort in the future.
