States with 100% Clean Energy Goals

wdt_ID State The Goal Comments
1 Arizona 100% carbon-free electricity by 2070 Adopted by order of the Arizona Commerce Commission in May 2021, extending and expanding the existing state RPS. Docket number RU-00000A-18-0284.
2 California 100% carbon-free electricity by 2045 2018 legislation (SB 100) extended and expanded the existing state RPS. State agencies are required to submit implementation plans by January 1, 2021. Also in 2018, Gov. Jerry Brown’s Executive Order B-55-18 set a goal of statewide carbon neutrality by no later than 2045, with net negative GHG emissions thereafter.
3 Colorado 100% carbon-free electricity by 2050 for Xcel Energy A 2019 law (SB 19-236) codified a pledge previously made by Xcel, whose service territory covers approximately 60% of the state’s load. It is mandatory “so long as it is technically and economically feasible.”
4 Connecticut 100% carbon-free electricity by 2040 Governor Ned Lamont’s 2019 Executive Order (Number 3) set a 2040 goal for carbon-free electricity and asked the Department of Energy and Environmental Protection to develop a decarbonization plan for the power sector, in line with previous legislation to cut economy-wide carbon emissions by 80% below 2001 levels by 2050.
5 District of Columbia 100% renewable energy by 2032 through the RPS The Clean Energy DC Omnibus Amendment Act of 2018 (DC Act 22-583) amended the existing RPS to mandate 100% renewable electricity by the year 2032.
6 Hawaii 100% renewable energy by 2045 through the RPS 2015 legislation (HB623) made Hawaii the first state to set a 100% RPS for the electricity sector.
7 Louisiana Net zero greenhouse gas emissions by 2050 Governor John Bel Edwards’ 2020 Executive Order (JBE 2020-18) established a Climate Initiatives Task Force to develop a roadmap and make recommendations.
8 Maine 100% clean energy by 2050 2019 legislation (LD 1494) increased Maine’s RPS to 80% by 2030, and set a goal of 100% by 2050. Also LD1679 sets an economy-wide goal of 80% cuts to greenhouse gases by 2050.
9 Massachusetts Net-zero greenhouse gas emissions by 2050 In 2020, the Secretary of Energy and Environmental Affairs set a 2050 net-zero GHG emissions goal under the authority of 2008 legislation. The same goal was then included in a March 2021 climate action law (Bill S.9). A decarbonization roadmap was released at the end of 2020.
10 Michigan Economy-wide carbon neutrality by 2050 Governor Gretchen Whitmer’s order in 2020 (Executive Directive 2020-10) set a goal “to achieve economy-wide carbon neutrality no later than 2050.” It directed the Department of Environment, Great Lakes, and Energy to develop a plan by the end of 2021.
