Policy Overview

For the first time in US history, carbon emissions from certain power plants are now regulated. In April 2024, the Biden Administration’s Environmental Protection Agency (EPA) finalized carbon standards for existing coal- and new gas-fired power plants, following several years of public comment. The structure of the standards was likely influenced by the June 2022 Supreme Court decision in the West Virginia v. EPA case, which limited the power of the EPA to regulate power sector emissions by ruling that the agency does not have the authority to direct power plants to shift from one generation source to another, such as from fossil fuels to renewable energy.

As a result, the standards do not explicitly authorize generation shifting and instead set staggered compliance pathways based on several factors. For example, coal plants planning to operate beyond 2039 and new gas plants that run 40% of the time both need to meet a 90% carbon capture rate by 2032. Coal plants that retire before 2039 need to meet a 40% gas co-firing requirement by the start of the decade, whereas coal plants slated to retire before 2032 are exempt.

The Trump administration has proposed a repeal of these standards. Carbon emissions from the existing gas fleet remain unregulated.

Policy Status

The Biden Administration finalized the carbon standards for existing coal- and new gas-fired power plants in April 2024, following comments on the official proposal announced in May 2023. Previously, in February 2024, the agency announced that it would remove the existing gas rule from the original proposal and re-introduce a more comprehensive rule later in the year that would address the entire fleet of gas-fired turbines and cover more pollutants. Although there was a non-regulatory docket to receive input on the design and scope of such a rule, the EPA failed to propose a formal regulation on existing gas emissions before the Trump Administration took office.

In March 2025, the Trump Administration’s EPA announced its intention to repeal the finalized carbon standards, which it officially initiated months later in June 2025. The public comment period closed on August 7, 2025.

Policy Engagement Overview

InfluenceMap's database covers roughly 1,000 companies and 300 industry associations globally, with the most engaged entities scanned on a weekly basis and all entities assessed at least every other quarter. The current state of corporate engagement on this regulation is summarized below. The graph to the right indicates InfluenceMap's capture of corporate positions on the regulation, ranging from strong opposition to strong support. Both this page and the graph were last updated on August 15, 2025.

As cautioned by InfluenceMap’s April 2023 briefing, many of the same utilities that opposed the Obama administration’s Clean Power Plan strongly opposed the Biden administration’s power plant carbon standards. InfluenceMap evidence shows particularly strong opposition from certain utilities and their industry groups, with a notable absence of advocacy from generally positive companies. This positioning has continued into the Trump administration, which has proposed a repeal of “all greenhouse gas (GHG) emissions standards for fossil fuel-fired power plants.”


Engagement on the Trump Administration's Proposed Repeal

InfluenceMap observed the following engagement trends during the Trump Administration’s proposed repeal comment period:

  • The utility sector maintained negative positioning on power sector regulation. Edison Electric Institute (EEI) and members including FirstEnergy and PPL Corp advocated for the proposed repeal of the carbon capture compliance pathways, supporting Trump EPA’s proposed finding that they were neither ”adequately demonstrated” nor “achievable.” EEI in particular questioned the legality of the compliance pathway as well as the staggered nature of the carbon standards, and called for the EPA to facilitate the buildout of new gas-fired generation.

  • The Midwest Ozone Group (MOG) endorsed the finding that regulation of fossil fuel power plants would not have a “significant” effect on GHG emissions. In its comments, MOG supported the Trump administration’s proposed finding that fossil fuel-fired power plants are not “significant contributors” of GHG emissions. Listed members in MOG’s comments include utilities Ameren, American Electric Power, Berkshire Hathaway, and Duke Energy as well as subsidiaries of FirstEnergy and PPL Corp; oil & gas companies including ExxonMobil and Marathon Petroleum; and industry groups including American Iron and Steel Institute and Steel Manufacturers Association.

  • Cross-sector industry groups advocated for deregulation. Several industry associations that continue to demonstrate misaligned positions on climate, including the US Chamber of Commerce and National Association of Manufacturers, advocated for the repeal of the standards.


Responses to the Biden Administration’s Finalized Standards for Existing Coal and New Gas Power Plants

  • In April 2024, Advanced Energy United CEO Heather O'Neill stated support for the rules while advocating for utilities to rapidly decarbonize, stating that “instead of looking to build new gas plants or prolong the life of old coal plants, utilities should be taking advantage of the cheaper, cleaner, and more trusty tools in the toolbox.”

  • Meanwhile, groups that continue to oppose science-aligned climate policy challenged the legality of the rules, with National Mining Association (NMA) and America’s Power filing a May 2024 joint petition for review and utilities American Electric Power (AEP), Duke Energy, and Vistra Corp filing a petition for review under the ad hoc coalition Electric Generators for a Sensible Transition; this coalition added more members – including Ameren, Evergy, PPL Corporation, Berkshire Hathaway, NRG, and Southern Company – when it filed an August 2024 emergency application for an immediate stay.


Engagement on the Biden Administration’s Existing Gas Plant Rule

Following the decision to separate the carbon standards for existing gas-fired power plants into a separate regulation, the Biden administration’s EPA opened a non-regulatory comment period from March 2024 to May 2024. EEI and major utilities – including American Electric Power, Ameren, Duke, PPL, and Southern -- submitted comments that strongly opposed an ambitious regulation and advocated for flexible compliance pathways.


Engagement on the Biden Administration’s Official Proposal

Positive Advocacy

  • Apple and Microsoft lone advocates from Big Tech: In August 2023, Apple submitted positive comments, advocating for the EPA to clearly define “low-GHG hydrogen” as hydrogen produced from new renewable resources. Microsoft signed one of the two joint letters organized by Ceres advocating for the EPA to expand the scope of coverage for affected power plants and move up compliance timelines. Dozens of other companies signed these letters, including Danone, Ikea, Salesforce, Starbucks, Trane Technologies, Unilever, and VF Corp. Alphabet, Amazon, and Meta appeared absent on these proposed rules.

  • Support from clean energy industry groups: Industry groups Advanced Energy United and Solar Energy Industries Association supported the ambition of the proposal.

No Public Engagement

  • Surprising utility silence: Higher scoring US utilities tracked by InfluenceMap, including Consolidated Edison, Exelon, Pacific Gas & Electric (PG&E), and Public Service Enterprise Group, appeared absent on the proposed rules by not submitting any individual comments. For example, although National Grid, NextEra, and PG&E advocated via the Energy Strategy Coalition – whose comments supported the use of CCS and low-GHG hydrogen while pushing for greater flexibility and other fuels such as renewable natural gas – they have not articulated their individual positions, aside from a May 2023 press release by PG&E in broad support. Similarly, Con Edison participated via the Clean Energy Group’s comments, which advocated for less stringent compliance timelines, while not offering any individual comments of its own.

Opposition

  • Main utility trade group spearheaded opposition: In August 2023 comments, EEI strongly opposed the ambition of the regulation and suggested that the EPA was acting beyond its legal boundary in proposing phased standards and the use of carbon capture and storage (CCS) and hydrogen, and emphasized that stringency of the proposed rules could delay the buildout of new fossil gas infrastructure. Several utilities seconded EEI’s negative position in their own comments, including Alliant, Berkshire Hathaway Energy, CMS Energy, Dominion Energy, DTE Energy, Entergy, and FirstEnergy. Subsequently, in December 2023 comments on the supplemental comment period, EEI repeated its concerns with the feasibility of the CCS and hydrogen compliance pathways and called for the EPA to extend compliance timelines and raise emissions thresholds. In February 2024, EEI appeared to link the EPA’s decision to remove the existing gas rule from the proposal with the industry group’s own negative engagement. Ameren, AEP, Duke, PPL Corp, Southern Company, and Xcel, in addition to the those listed above, emphasized the same narrative as EEI, namely that the uses of CCS and hydrogen were not feasible at the proposed timeline and scale. Many of these utilities signed the August 2023 comments submitted by the Class of ‘85 Regulatory Response Group and the Power Generators Air Coalition, both of which pushed back on the proposed rules and suggested that the EPA was acting beyond its legal boundary. (See InfluenceMap’s April 2023 briefing for more details on members of the Class of '85 and PGen). Several utilities maintained their oppositional positions in December 2023 comments submitted to the supplemental comment period, including Ameren, Duke, and Southern Company.

  • A shift by Edison International: Edison International CEO Pedro Pizarro, who at the time served as the EEI Chair, stated in an August 2023 interview with the Los Angeles Times that “there’s no daylight between Southern California Edison and Edison Electric Institute on this particular topic. I have my Edison hat and my EEI hat on at the same time, because they have the same view.” This statement marked a departure from the utility’s typically more positive engagements (e.g., supporting the Clean Power Plan and the EPA’s right to regulate carbon emissions).

  • Constellation disagreed with EEI’s negative position, but still advocated for weaker rules: In an August 2023 press release, CEO Joseph Dominguez stated that he was “disappointed to see many of my peers represented by the Edison Electric Institute and others working to block these very practical measures.” On the other hand, Constellation also strongly advocated against a clear definition of “low-GHG hydrogen” as well as the inclusion of any additionality criteria around the use of hydrogen.

  • Strong opposition from trade groups: Many industry groups opposed the proposed rules, including API, America’s Power, Business Roundtable, National Association of Manufacturers, National Federation of Independent Business, and NMA. In August 2023 joint comments, the US Chamber of Commerce, American Fuel & Petrochemical Manufacturers, and American Chemistry Council called for the EPA to withdraw the proposal. America’s Power CEO Michelle Bloodworth directly called for a withdrawal of the rules in a statement at the Federal Energy Regulatory Commission’s November 2023 Reliability Technical Conference.

US Chamber and National Association of Manufacturers advocate for repeal of power plant carbon standards

19/06/2025

In separate 11 June press releases, the US Chamber of Commerce and the National Association of Manufacturers (NAM) celebrated the Trump administration's proposal to repeal the power plant carbon standards, which were finalized by the Biden administration in April 2024. The US Chamber stated that it "supports terminating the unworkable Clean Power Plan 2.0", while NAM CEO Jay Timmons called the proposed repeal a "critical and welcome step toward rebalanced regulations and American energy dominance." The proposal is open for comment until 7 August 2025, and reflects the Trump administration's latest in a series of regulatory rollbacks.

Advanced Energy United CEO advocates against repeal of US power plant carbon standards

19/06/2025

In an 11 June press release, Advanced Energy United CEO Heather O'Neill opposed the Trump administration's proposed regulatory repeal of the finalized power plant carbon standards. O'Neill emphasized the need to transition away from fossil fuel power plants, stating that "continuing to invest in and depend on these plants into the future will lead to more stranded costs and price volatility for consumers."

The standards, which were finalized by the Biden administration in April 2024, will soon be open for public comment as the Trump administration proposes to rollback all GHG emissions standards for the power sector under the Clean Air Act; as stated in the Environmental Protection Agency's press release, the Trump administration is "proposing that greenhouse gas emissions from fossil fuel-fired power plants do not contribute significantly to dangerous air pollution within the meaning of the statute."

Industry groups call for regulatory rollback in the US

10/01/2025

Industry groups and state chambers of commerce, including the National Association of Manufacturers, the American Chemistry Council, the American Forest and Paper Association, the American Iron and Steel Institute, the American Wood Council, the National Mining Association, the National Propane Gas Association, the Steel Manufacturer's Association, and the Tennessee Chamber of Commerce and Industry, among others, released a joint letter on December 5th to incoming President Trump and his Cabinet selections advocating for the rollback of "restrictive regulations." The letter specifically requested for the new administration to repeal Biden's LNG export ban, replace the EPA's power plant rules for existing fossil fuel generators, pause updates to the Department of Energy's energy efficiency standards for appliances, and accelerate the permitting process for energy projects. The letter also criticized the US' position on the UN Global Plastics Treaty, emphasizing the need to advance "demand-side policies" to address plastic pollution rather than pursuing limitations on certain plastic uses.

Edison Electric Institute opposes Supreme Court decision on US EPA power plant rules

24/10/2024

As reported by a 16 October Politico article, Edison Electric Institute (EEI) stated "disappointment" with the US Supreme Court's decision to decline applications for a stay of the Environmental Protection Agency (EPA)'s finalized power plant carbon standards, which effectively allows the rules to remain in place. These rules establish emissions reductions targets for existing coal and new gas power plants, with compliance pathways that include carbon capture and sequestration (CCS). The article further described that EEI would continue to question the legality of these rules, and specifically the CCS pathway, before the District of Columbia Circuit. This legal action marks the latest in EEI's strategic opposition to these power plant rules over the past two years.

American Petroleum Institute does not support US EPA’s finalized GHG emissions standards for existing coal and new gas plants

02/05/2024

In a statement released on April 25th, the American Petroleum Institute (API) did not support the US Environmental Protection Agency (EPA)'s finalized emissions standards for existing coal and new gas plants, claiming that the rules would affect grid reliability.

Advanced Energy United CEO supports finalized power plant rules for existing coal and new gas plants in the US

02/05/2024

In an April 25th press release, Advanced Energy United President and CEO Heather O'Neill stated support for the finalized federal standards addressing GHG emissions from existing coal and new gas plants. O’Neill emphasized that utilities “need to do right by ratepayers” and transition rapidly away from fossil fuels, rather than building new gas plants or prolonging existing coal plants.

Edison Electric Institute links previous negative engagement on the US EPA’s power plant proposal with weakening of final regulation

07/03/2024

As reported by Reuters in a Feburary 29th article, Edison Electric Institute (EEI) celebrated the US Environmental Protection Agency (EPA)'s decision to remove the existing gas rule from its power plant proposal. EEI appeared to link this agency decision to the industry group’s own negative engagement on the rules, stating that “we appreciate that EPA has acknowledged our concerns with the proposed regulations for existing natural gas.” EEI did not appear to make any clear statements on the raised ambition of the EPA’s eventual re-proposal of the existing gas rule, which the agency has said will cover the entire gas-fired power plant fleet. The existing gas rule proposed to address only the largest gas plants in the country.

Edison Electric Institute continues to push back on US EPA’s power plant proposal

07/03/2024

As reported by E&ENews in a February 21st article, Edison Electric Instiute (EEI) made unsupportive statements on the Environmental Protection Agency (EPA)’s draft power plant rules. During the industry group’s Electric Power Industry Outlook presentation in Wall Street, EEI’s executive vice president for clean energy and general counsel appeared to suggest legal action against the proposed rules unless their compliance pathways were weakened, stating that if the current ambition of the proposal is finalized then it’s “likely to be a litigation issue.” EEI also appeared to support a prolonged role for fossil fuel plants, citing reliability concerns in light of increased demand for electricity.

National Mining Association continues to oppose the US EPA's power plant emissions standards

24/08/2023

In an August 2023 Twitter post from National Mining Association CEO Rich Nolan, the association continued to oppose the US Environmental Protection Agency (EPA)'s new power plant emissions standards on account of coal fired power plant closures, claiming that the nation's energy future "hangs in the balance".
