Colorado

Colorado has over two decades of climate action that includes establishing a renewable portfolio standard in 2004 and emissions reductions goals in 2008. Net emissions decreased 9% from 2005-2021, compared to their mandatory emissions reduction target of 26% below 2005 levels by 2025. Ranking 5th in the country for crude oil production and 8th for natural gas production, over half of in-state electricity generation comes from coal and natural gas, complemented by almost 40% from renewables, which has more than quadrupled since 2010 and is dominated by wind.
