In the roughly two years since the Alliance was launched, the coalition has grown to twenty-five governors — both Democrats and Republicans — representing 55% of the U.S. population and 60% of U.S. GDP. 

Through thoughtful, coordinated state action, these governors are filling the federal leadership void, aiming to reduce their collective greenhouse gas (GHG) emissions by at least 26 to 28% below 2005 levels by 2025, with many adopting substantially more ambitious emission reduction targets. Generating 40% of U.S. GHG emissions, this coalition is equivalent to the world’s sixth largest emitter. 

Today the Alliance has become an entity of global importance, capable of making a genuine impact on global emissions through its leadership and action.
