Who They Are

Marathon Petroleum Corporation. The largest petroleum refiner in the United States ($150+ billion revenue, 2024), operating 13 refineries with a combined crude oil throughput capacity of approximately 3 million barrels per day. Marathon was formed in 2011 as a spinoff from Marathon Oil; in 2018 acquired Andeavor ($23 billion) to become the nation’s dominant refiner; in 2021 divested Speedway ($21 billion) to 7-Eleven.

Marathon’s refining operations are concentrated in the Midwest and Gulf Coast — including facilities in Detroit (adjacent to the 48217 zip code, the most polluted zip code in Michigan) and Louisiana’s Cancer Alley. The company operates one of the most documented covert anti-EV campaigns in fossil fuel dark money history (2018–2019), extensively investigated by the New York Times, HuffPost, and The Intercept.

Marathon is the most Republican-aligned major oil company, directing 91–98% of PAC contributions to Republican candidates (consistent across all measured cycles 2012–2024). Marathon’s political operation: $892K–$1.89M per cycle in PAC contributions, $2–10 million annually in federal lobbying (peak $4.96M in 2018 during CAFE rollback and Andeavor acquisition). Political spending focused on opposing EPA emissions regulations, refinery safety requirements, environmental justice enforcement, EV incentives, and RFS (Renewable Fuel Standard) compliance mandates. Marathon’s refineries disproportionately impact communities of color — a pattern that environmental justice advocates have documented extensively.


What They Want

Opposition to EPA refinery emissions standards, reduced Clean Air Act enforcement, favorable renewable fuel standard compliance rules (RFS compliance costs are significant for refiners), opposition to carbon pricing, elimination of electric vehicle tax credits and incentives, and liability protection against environmental justice lawsuits.

FEC Enforcement Action (2022): The Federal Election Commission fined Marathon Petroleum $85,000 for illegally contributing $1 million to federal contractor-prohibited outside spending groups in summer 2020. Federal contractors are barred from making political contributions while negotiating or performing federal contracts. Marathon sent $500,000 each to Senate Leadership Fund and Congressional Leadership Fund. The FEC described it as “the largest federal contractor contributions to an outside spending group that the Commission has considered in an enforcement matter.” The Campaign Legal Center filed the complaint; the FEC unanimously accepted a conciliation agreement.


The Covert Anti-EV Campaign (2018–2019): Dark Money Documented

Marathon Petroleum ran one of the most extensively documented covert fossil fuel dark money campaigns in recent history, investigated and reported by the New York Times, HuffPost, and The Intercept. The campaign demonstrates the complete architecture of oil industry opposition to clean energy policy: congressional letter drafting, ALEC model bills, dark money digital campaigns, EPA Administrator access, and tax credit opposition lobbying.

Contradiction

Marathon’s official stance: We support free market principles and are not opposed to electric vehicles. Internally and through dark money: We will use every available lever to block EV adoption, fuel economy standards, and state-level EV incentives — via congressional letter orchestration, ALEC bills, dark money Facebook campaigns generating 25% of DOT comments, and EPA access.

The Campaign Architecture:

1. Congressional Letter Campaign & Draft Coordination:

Marathon drafted a letter opposing CAFE (Corporate Average Fuel Economy) standards and circulated it among members of Congress. Nineteen lawmakers from Indiana, West Virginia, and Pennsylvania subsequently sent letters to the Transportation Department containing phrases quoted verbatim from Marathon’s industry letter. The talking points reframed fuel efficiency as a consumer freedom issue (“choice in vehicles that best fit their needs”) rather than federal energy policy, directly contradicting decades of U.S. energy law. The copied language appeared in official congressional correspondence, creating the appearance of independent legislative opposition masking Marathon’s orchestration.

2. ALEC Model Legislation Strategy:

Marathon coordinated with the American Legislative Exchange Council (ALEC) to draft model legislation blocking state-level EV incentive programs. ALEC’s guide described current fuel-efficiency rules as “a relic of a disproven narrative of resource scarcity.” ALEC’s corporate members and affiliated state legislators then circulated the template legislation in state legislatures — a turnkey operation for replicating anti-EV policy across states. Specific model bills included the Asphalt Industry Alliance Act and gas tax preservation measures designed to protect liquid fuel revenue streams.

3. Dark Money Facebook Campaign (25% of DOT Comments):

A Facebook dark money campaign covertly run by Transportation Energy Partners LLC (an oil industry front group representing ExxonMobil, Chevron, Phillips 66, and other majors) generated extraordinary comment volume on fuel economy standards. A New York Times analysis found that 25% of the 12,000 public comments received by the Department of Transportation could be traced to this single petition — meaning one astroturf campaign generated one-quarter of all public input. The ads linked to a website using a photo of Obama with the question “Would YOU buy a used car from this man?” — negative framing designed to mobilize opposition. This demonstrates how digital dark money can manufacture the appearance of grassroots opposition while being entirely funded and directed by corporate interests.

4. ALEC Event Strategy:

Marathon sponsored a major event in New Orleans attended by 1,500 state legislators and officials. Transportation Secretary Elaine Chao attended and praised the administration’s “regulatory reforms.” The event served as a coordination mechanism for state legislatures to align on anti-EV policy — a nationwide campaign orchestrated through a private corporate-sponsored event.

5. EPA Administrator Direct Access:

Marathon CEO Gary Heminger met multiple times with EPA Administrator Scott Pruitt after Pruitt’s appointment. Marathon had been a major donor to Pruitt’s earlier campaigns in Oklahoma. EPA FOIA records show sustained email coordination between Marathon lobbyist Michael Birsic and EPA scheduling staff to arrange CEO-to-Administrator meetings focused on “RFS and air regulations.” The pattern demonstrates how corporate donations create direct regulatory access.

6. EV Tax Credit Opposition & Barrasso Bill:

Marathon representatives spoke at an ALEC meeting in Washington (November 2018, attended by ~1,500 state legislators) against the federal EV tax credit. The oil refiners voted through a resolution calling for Congress to scrap the $7,500 subsidy. Marathon lobbied on Senator John Barrasso’s bill (who received $15,000 from Marathon and $15,400 from Koch Industries) to eliminate the EV tax credit entirely and add a new user fee on EV owners. Marathon reported spending $910,000 on lobbying in the final three months of 2018 that included the Barrasso EV bill.

7. AFPM Collective Campaign (2023–2024):

Marathon is a lead member of the American Fuel and Petrochemical Manufacturers (AFPM), which collectively spent a record $7 million on federal lobbying in 2023. AFPM ran a seven-figure swing-state ad campaign in Ohio, Pennsylvania, Michigan, Wisconsin, Arizona, Nevada, and Georgia portraying EPA’s tailpipe emissions standards as a “car ban.” The framing successfully influenced policy discourse — the 2025 One Big Beautiful Bill Act incorporated the “car ban” language, and EV tax credits were entirely eliminated.

Company Response:

When confronted by E&E News about the covert campaign, Marathon spokesman Chuck Rice stated: “Consistent with our free market principles, Marathon Petroleum supports efforts to remove or limit subsidies for electric vehicles,” describing the EV tax credit lobbying as “minimal.”


What They’ve Gotten

EV Tax Credit Elimination (2025): The covert anti-EV campaign (2018–2019) directly produced the 2025 One Big Beautiful Bill Act, which eliminated EV tax credits entirely. This represents a complete policy victory: Marathon’s dark money campaign and legislative lobbying transformed into law eliminating a major driver of EV adoption.

EV Mandate Opposition Victory (2022–2025): Marathon is a lead member of the American Fuel and Petrochemical Manufacturers (AFPM), which collectively (with Chevron, Valero, Occidental) spent a record $7 million on lobbying in 2023. AFPM ran a seven-figure ad campaign in seven swing states calling emissions rules a “car ban.” The framing succeeded — the 2025 One Big Beautiful Bill Act incorporated the “car ban” language, and EV tax credits were eliminated.

PAC Contributions: Marathon PAC gave $649,000 to federal candidates in 2023–2024, with 91% to Republicans. This concentrated giving aligns with Marathon’s strategy of supporting the most anti-regulatory candidates and parties.

Environmental Justice Exemptions: Marathon’s Detroit refinery operates within a mile of residential neighborhoods in the 48217 zip code — a majority-Black community with asthma rates 3x the national average and cancer rates significantly above state averages. Despite decades of community complaints and documented health impacts, Marathon has successfully resisted regulatory action that would require significant emissions reductions. The refinery’s location — in a politically marginalized community — insulates it from the political pressure that would force closure or major investment in a wealthier, whiter neighborhood.

RFS Compliance Flexibility: Marathon has lobbied successfully for EPA to provide compliance flexibility under the Renewable Fuel Standard — the requirement that refiners blend ethanol into gasoline or purchase Renewable Identification Numbers (RINs). The compliance cost ($1-3 billion annually for the largest refiners) is Marathon’s biggest political priority, and the company has secured regulatory accommodations that reduce this cost.

Money

Marathon Petroleum’s $5-10 million annual lobbying investment protects a $150+ billion revenue stream by opposing the environmental regulations that would internalize the health costs its refineries impose on surrounding communities. The 48217 zip code in Detroit — where Marathon’s refinery produces pollution linked to elevated cancer and asthma rates — demonstrates the environmental justice dimension: the communities most affected by Marathon’s operations are the communities with the least political power to demand remediation. Marathon’s lobbying ensures that the health costs of refining ($2-4 billion annually in estimated health impacts from refinery pollution nationally) are borne by communities rather than by shareholders.
