Climate Policy Engagement Analysis
Formerly an Exelon business, Constellation launched as a standalone company in February 2022. Any climate policy engagement from Constellation prior to February 2022 can be found in Exelon’s profile.
Climate Policy Engagement Overview: Constellation demonstrates policy engagement that is partially aligned with policy pathways aiming to deliver the temperature goals of the Paris Agreement. The company engages on climate policy with a mix of positive and negative positions, with evidence of advocacy at the federal level and across several states, including Maine, Massachusetts, and New York. Although Constellation demonstrates some positive top-line messaging, it advocates for the long-term role for fossil gas and weak implementation measures around hydrogen production. Constellation is a member of industry groups that strategically advocate for fossil fuels, including the Business Roundtable.
Top-line Messaging on Climate Policy: Constellation demonstrates positive top-line messaging on climate policy. The company suggested support for government policy to address climate change in its latest Sustainability Report published in June 2025, and CEO Joseph Dominguez previously articulated his support for a climate-neutral economy by 2050 in an August 2023 interview with the Washington Post. Constellation’s Climate Change Policy document, which has not been updated since August 2022, stated support for the goals of the Paris Agreement.
Engagement with Climate-Related Policy: Constellation appears to engage with mostly positive positions on climate-related policy, although with seemingly less activity in recent years. At the federal level, the company pushed for greater ambition in February 2023 comments on the Environmental Protection Agency (EPA)’s supplemental methane proposal. At the state level, Constellation broadly supported New York’s renewable energy goals in July 2022 comments on the state’s climate plan and, as reported by a July 2022 S&P Global article, advocated for Pennsylvania’s participation in the Regional Greenhouse Gas Initiative.
Positioning on Energy Transition: Constellation demonstrates inconsistent positions on the energy mix, occasionally urging ambitious action to transition the energy mix while advocating for new fossil fuel infrastructure. Constellation’s strategic engagement on the Biden administration’s power plant carbon standards highlights this pattern: although the company’s CEO — in contrast to the utility sector’s mostly obstructive positions — strongly supported the ambition of the proposal in May 2023 and expressed disappointment with Edison Electric Institute’s opposition to the proposed use of hydrogen and carbon capture technologies to reduce emissions, the company submitted August 2023 comments that advocated for the EPA to recognize a prominent role for gas. However, in response to the Trump administration’s proposed repeal of these standards, Constellation submitted August 2025 comments that questioned the EPA’s rationale for removing the carbon capture and gas co-firing compliance pathways, but still offering broad support for the repeal. In an August 2023 earnings call, Constellation’s CEO characterized fossil gas an “an important bridge fuel.” Positively, Constellation participated in the Ceres LEAD 2025 advocacy event in March 2025 to directly advocate for policymakers to maintain the Inflation Reduction Act’s federal clean energy tax credits.
Constellation also actively engaged on hydrogen-related policy, with repeated opposition to the Inflation Reduction Act’s “three pillars” requirements for its clean hydrogen tax credit. The company specifically criticized the additionality requirement, a mechanism that ensures hydrogen is produced from new clean energy projects only, in multiple engagements: the company submitted February 2024 comments, a May 2023 joint letter organized by the Fuel Cell and Hydrogen Energy Association, and another May 2023 joint letter that challenged the legality of the proposed requirements and advocated for the tax credit to allow hydrogen produced from existing nuclear resources. Upon the release of the finalized guidance in January 2025, Constellation’s CEO celebrated the final rule’s allowance for existing nuclear but did not comment on the ambition of the other requirements.
Industry Association Governance: Constellation discloses its industry association memberships on its corporate website, but does not provide details on each group’s climate policy positions. The company does not appear to have published a review of its industry association memberships and climate policy engagement. Constellation is a member of the Business Roundtable, which advocates for policies toward fossil gas infrastructure buildout. While Constellation was listed as a member of American Gas Association in 2023, it is unclear if it remains a member in 2025. Similarly, although Constellation is no longer listed as a member for the Tennessee Chamber of Commerce & Industry in 2025, it still appears on the “Money-Saving Programs” webpage as an energy partner.
