Climate Policy Engagement Analysis
Climate Lobbying Overview: Exelon demonstrates policy engagement that is partially aligned with policy pathways aiming to deliver the temperature goals of the Paris Agreement. The company engages on US climate policy with a mix of positive and negative positions, with an advocacy presence at the federal level and across several states including Illinois, Maryland, and New Jersey. The company’s history of support for federal climate regulations contrasts with its active opposition to state and local decarbonization measures, particularly via its subsidiaries in Maryland. Exelon CEO Calvin Butler serves as Chair for Edison Electric Institute and the company is a board member of the American Gas Association, two industry groups which continue to advocate for fossil gas infrastructure.
Top-line Messaging on Climate Policy: Exelon appears to have positive top-line communications on climate policy. Its corporate website, last accessed in August 2025, recognizes the need for urgent action to address climate change by stating that “all nations must work to transform their energy use toward carbon neutrality.”
Engagement with Climate-Related Policy: Exelon appears to engage on climate-related policies with a mix of positions, including at the state level. In Maryland, subsidiaries submitted February 2025 comments against community solar legislation. The year prior, subsidiary BGE submitted March 2024 testimony and February 2024 testimony that emphasized concerns with the Brighter Tomorrow Act, which increased incentives for solar energy in the state. Meanwhile, in New Jersey, subsidiary Atlantic City Electric provided April 2025 testimony that appeared to express support for community solar.
Positioning on Energy Transition: Exelon demonstrates a mix of positions on the energy transition, supporting transport electrification measures while advocating for a long-term role for fossil gas. For example, in a September 2023 New York Times interview, CEO Butler appeared to support transport electrification while emphasizing the costs in transitioning toward a low-carbon economy. A year later, in a TIME interview, Butler stated that “gas is going to be part of this equation for the foreseeable future.”
At the state level, Exelon advocated for New Mexico to adopt the Advanced Clean Cars II and Advanced Clean Truck rules in an August 2023 comments with the Corporate Electric Vehicle Alliance. However, the company’s subsidiaries have consistently opposed building electrification measures in Maryland in recent years: for example, BGE submitted March 2025 testimony and March 2023 testimony opposing measures to rapidly electrify buildings, which followed February 2023 and January 2023 testimonies against Howard County’s all-electric building standard proposal. BGE also opposed Montgomery County Bill 13-22, which would require all-electric building standards for new construction and major renovations by 2024, in October 2022 and July 2022 testimonies. Exelon subsidiaries have also been active on regulatory investigations into the long-term role of gas, although with unclear positions on the transition of energy mix: Atlantic City Electric submitted September 2023 comments on the New Jersey gas proceeding and ComEd submitted July 2024 comments on the Illinois Future of Gas proceeding.
Industry Association Governance: Exelon discloses its contributions to industry associations on its corporate website, however without including an account of each group's climate positions and engagement activities. The company does not appear to have published a review of its industry association memberships and climate policy engagement. As of June 2025, CEO Calvin Butler serves as Chair for Edison Electric Institute, which continues to oppose the ambition of the power plant carbon standards finalized by the Biden administration. Exelon is a member of the US Chamber of Commerce and a board member to the American Gas Association, two industry groups that continue to obstruct US climate policy.
