The largest US companies’ climate lobbying records

New InfluenceMap research reveals that a majority of the largest companies headquartered in US states are not actively supporting climate policy, including in their home states. With federal progress stalled, advocates frequently look to state or city-level action; however, this analysis indicates that many powerful corporate actors are not engaging in support of subnational progress. Using the 2025 Fortune 500 list, InfluenceMap identified the largest company by revenue in each of the 50 states. Seven states were excluded from the final analysis as they do not host a Fortune 500 company.

Of the 43 largest companies assessed, 29 (67%) appear unengaged on climate policy, while only 14 companies (roughly one third) are actively engaged. The 29 low-engaging companies have negligible “Engagement Intensity” (EI) scores of 5% or lower. InfluenceMap could not find sufficient public evidence of their climate policy advocacy to determine an Organisation Score. The 14 engaged companies hold EI scores between 6% and 36%. These unengaged companies primarily belong to the healthcare, pharmacy, and health insurance sectors, including major entities such as CVS Health in Rhode Island, UnitedHealth Group in Minnesota, and Cigna in Connecticut. Other unengaged firms are largely in financial services, insurance, national retail, and grocery chains, such as Northwestern Mutual, Home Depot, and Publix. Less common on this list are pipeline companies like Oneok and forest product firms like Domtar.

The low-engaged companies span a wide revenue range, from Knife River ($2,899 million) to CVS Health ($372,809 million). Conversely, the 14 engaged companies typically come from more active sectors like energy (ExxonMobil), transportation (FedEx and General Motors), and information technology (Amazon and Apple). DuPont is the only chemical company on the list, showing an EI of 15% with a mix of positive and negative positions. While most banking firms are low-engaged, exceptions include JPMorgan Chase (23% EI) and Bank of America (12% EI). Revenue in the engaged group ranges from Hawaiian Electric Industries ($3,638 million) to Walmart ($680,985 million).

Walmart also emerges as the largest private employer in nearly half of the 50 states, yet it has a relatively low EI of 14%. Despite advocating for the federal Inflation Reduction Act in 2022, InfluenceMap has found little recent evidence of positive advocacy for climate policy or state-level engagement from the company.

The state climate lobbying landscape

InfluenceMap analysis consistently shows that vested interests—including industry associations, energy utilities, and oil and gas companies—dedicate massive lobbying efforts to subnational climate policy. This landscape has become more complicated following the rollback of the Inflation Reduction Act’s clean energy incentives. Some states now claim their own climate targets have fallen out of reach. For instance, New York recently rolled back its climate law following years of lobbying from the state’s business league and oil and gas interests.

In New York

In New York, neither JPMorgan Chase nor Walmart advocated on the state’s climate plan or building electrification law. In contrast, the largest utility, Consolidated Edison (ConEd), frequently advocates on New York climate policy. ConEd sought to weaken provisions of the 2022 Scoping Plan, although it appeared to support the law more actively in 2023 and 2024. However, in 2025, ConEd advocated to weaken New York’s building electrification law. The state’s primary trade association, the Business Council of New York State (BCNYS), has also advocated heavily against the state’s climate law, endorsing its rollback in 2026 and opposing building electrification. BCNYS has also opposed legislation mandating that large businesses disclose greenhouse gas emissions.

State-level industry associations

State-level industry associations demonstrate highly active and negative engagement on climate and energy regulations. InfluenceMap has assessed seven state Chambers of Commerce, including those in California, New York, and Texas. All seven actively engage in opposition to climate policy and the energy transition in their respective states.

Energy utilities

Energy utilities tend to lobby actively in the states they serve, with many continuing to advocate in favour of fossil fuels. None of the 27 US utilities currently assessed by InfluenceMap lobby on climate policy in full alignment with scientific recommendations.

In California

In California, neither Amazon nor Apple has actively supported recent state climate policies, despite holding generally positive positions. Meanwhile, the California Chamber of Commerce (CalChamber) advocates heavily against the state’s energy transition. In September 2025, CalChamber opposed California SB 57, and in February 2026, it joined a lawsuit arguing that California’s greenhouse gas disclosure law is unconstitutional. While Amazon supported power sector decarbonisation under California SB-410 in July 2024, it has not engaged since. Similarly, Apple supported disclosure legislation in 2023 but has shown no public evidence of recent advocacy.
