  • Thirteen jurisdictions have goals that include both: (1) at least 75% reductions in greenhouse gas emissions, and (2) at least 75% of electricity production from renewable or combined renewable and clean energy production, by not later than 2050. Those states are designated with green shading plus green squares or circles on the map.
  • States with renewable or clean energy portfolio standards but not greenhouse gas standards are indicated on the map with yellow shading. Four of those, indicated by blue squares, have the goal of achieving 100% renewable or combined renewable and clean electricity by 2050 or sooner.
  • Many of the state goals address not only electricity production and use, but also include transportation fuels and heating fuels.
  • Climate Watch, managed by the World Resources Institute, tracks up-to-date information about countries that have adopted net-zero emissions goals, by “law, policy, or high-level political pledge such as head of state commitment.” By April 2021, Climate Watch reports 59 countries, representing 54% of global GHG emissions, have communicated net-zero emissions goals. 
  • In addition, hundreds of cities and dozens of the world’s largest corporations, including fossil fuel companies and major U.S. utility companies, have made similar GHG and renewable energy commitments.

Minnesota (May 2021)

80% below 2005 levels by 2050

~30% by 2020 (for IOUs, differs by utility)

Minnesota Governor Tim Walz, in Executive Directive 19-37, established a Climate Change Subcabinet and Governor’s Advisory Council on Climate Change.

In March 2019, Governor Tim Walz and Lieutenant Governor Peggy Flanagan announced their One Minnesota Path to Clean Energy policy proposals intended to achieve 100% clean energy in the state’s electricity sector by 2050.

The Minnesota House Climate Action Caucus (58 of 134 representatives) introduced its Minnesota Climate Action Plan in October 2020. That plan calls for “a 45% reduction in GHG emissions by 2030 . . . [and] a carbon free future by 2050.” It also includes proposals for “supporting communities statewide with resources to adapt to climate change and build local resilience.”  

In the 2021 legislative session, two new Minnesota laws were passed, which require GHG emissions analysis. The Energy Conservation and Optimization (ECO) Act requires GHG analysis and net reductions in state GHG emissions for utility energy efficiency measures that include fuel-switching. An, and Act amending Minnesota agricultural law requires that cellulosic biomass sourcing plans include detailed explanations of how greenhouse gas emissions will be reduced.

North Dakota Governor Doug Burgum has issued a call for North Dakota to be carbon neutral by the end of this decade. He included that goal in his statements to the Williston Basin Petroleum Conference in May, and touted not “federal mandates or state regulations” but instead called for innovation. 

Governor Burgum continued and expanded on these themes in public reports of meetings in May and June with representatives of companies planning to build a clean hydrogen hub in North Dakota and with U.S. DOE Secretary Granholm and EPA Administrator Regan.

In the 2021 legislative session, North Dakota passed a series of bills with CCUS implications:

·     House Bill 1452 allocates $25 million to create a Clean Sustainable Energy Fund to support low-emission technology projects;

·     Senate Bill 2328 grants a tax credit of $0.75 per million BTUs of flared gas captured by an oil well flare mitigation system;

·     Senate Bill 2152 adds geologic storage of carbon dioxide to the sales and use tax exemption; and,

·     Senate Bill 2206 allows utilities to recover R&D costs for CCUS including “a reasonable rate of return on capital expenditures” and authorizes rate recovery plus reasonable financial incentive for PPAs for “a dispatchable on-demand generating unit, plant, or facility deemed to protect grid reliability.”



8.5% by year-end 2026 for both IOUs and competitive suppliers

Ohio law describes the Commission’s responsibilities for both electric and natural gas services, including directives related to achieving environmental mandates. The state policy calls for utility regulations that, “facilitate” the state’s effectiveness or competitiveness “in the global economy.” PUCO hears Economic Development Project (EDP) cases for both electric and natural gas utilities.

The Oregon PUC is working to meet the directives in Governor Brown’s March 2020 Executive Order (EO) 20-04. See the PUC’s March 2021 Update. The EO required the PUC and many other state agencies to consider efforts to reduce GHG emissions and their effects on impacted communities. Among many directives, the PUC is focusing on: (1) Whether utility portfolios and customer programs that factor in GHG emissions and costs will reduce risks and costs to utility customers; and (2) Prioritizing proceedings and activities that advance decarbonizing the utility sector using the PUC’s broad statutory authority.

100% by 2050


Rhode Island (April 2021)

Net-zero by 2050

38.5% by 2030; 100% by 2030 (goal)

2021 Act on Climate Law was signed April 10 and takes immediate effect. “The state will develop a plan to incrementally reduce climate emissions to net-zero by 2050. The plan will be updated every 5 years and will address areas such as environmental injustices, public health inequities and a fair employment transition as fossil-fuel jobs are replaced by green energy jobs.”

A report issued by the Rhode Island Office of Energy Resources (OER) details pathways and policies for meeting 100% of R.I. electricity demand with renewables by 2030.

South Dakota


A voluntary electric utility objective, with no penalty or sanction for not meeting it, was set at 10% of retail sales for 2015, “obtained from renewable, recycled, and conserved energy sources.”



80-95% below 1990 levels by 2050

55% tier one renewables by 2017; 75% by 2032




100% carbon-free by 2050


(May 2021)

Washington law (RCW 70A.45.020, 2020) requires the state to reduce GHG emissions to 1990 levels by 2020, then reduce by another 45% by 2030, 70% by 2040, and 95% and achieving “net zero” GHG emissions by 2050.

This goal is economy-wide, and includes the transportation sector. Washington’s Utilities and Transportation Commission (UTC) has several responsibilities for electric utility participation in electric vehicles..  

The state’s RPS is set at 15% of electric load by 2020 and thereafter. Washington policy (RCW 19.285.040) calls for qualifying electric utilities to “pursue all available conservation that is cost-effective, reliable, and feasible.” And, Washington’s Clean Energy Transformation Act of 2019 (RCW 19.405) sets goals to “eliminate coal-fired electricity, transition the state's electricity supply to one hundred percent carbon-neutral by 2030, and one hundred percent carbon-free by 2045.”

Washington law also defines and includes provisions for renewable natural gas and renewable hydrogen (RCW 54.04.190). Washington natural gas companies may propose, and the Commission may approve, retail renewable natural gas programs. (RCW 80.28l.385), and all natural gas companies must offer voluntary RNG tariffs (RCW 80.28.390).

Washington Governor Jay Inslee signed a climate change legislation package on May 17, 2021. The package includes “the Climate Commitment Act, environmental justice legislation, a clean fuels standard and bills related to reducing Washington’s single-use plastic waste and hydrofluorocarbon pollution.” SB1526, establishes a cap-and-invest program. A Seattle Times article explains, the new laws call for net-zero emissions, economy-wide, by 2050, and establishes emissions caps for the state’s 100 largest emitters, covering about 75% of total state GHG emissions. 

Washington’s Energy Independence Act (RCW 19.285, 2007 as amended) declares that “Increasing energy conservation and the use of appropriately sited renewable energy facilities… will promote energy independence… stabilize electricity prices for Washington residents, provide economic benefits for Washington counties and farmers, [and] create high-quality jobs in Washington… .”

Washington law also directs the Commission to establish a “social cost of carbon” and use it in regulatory impact analyses (RCW 80.29.405). Gas utilities must apply the social cost of carbon “including the effect of emissions occurring in the gathering, transmission, and distribution of natural gas to the end user,” when modeling conservation program benefits. (RCW 80.28.380 and RCW 80.28.395).


Governor Tony Evers’  Executive Directive #38 of 2019 sets a goal for 100% zero-carbon by 2050 for all electricity consumed in Wisconsin, and directs the state’s new Office of Sustainability and Clean Energy to “fulfill[] the carbon reduction goals of the 2015 Paris Climate Accord.”

RPS of 10% by 2015 has been achieved and continues. 

The Commission’s mission statement includes “environmentally responsible utility services and equitable access to telecommunications and broadband services.”

In his 2021-23 budget proposal, Wisconsin Governor Tony Evers “recommends” the commission establish the social cost of carbon, update it biennially, and “consider the social cost of carbon when evaluating construction certifications.”
