This scorecard provides a detailed breakdown of InfluenceMap's assessment of Marathon Petroleum's disclosures on climate policy engagement. This does not include an assessment of the company's real-world climate policy engagement, which can be found on InfluenceMap's online profile of Marathon Petroleum, accessible via the buttons on the right hand side of the page.
The disclosure assessments are directly integrated into the CA100+ Net Zero Company Benchmark as part of InfluenceMap's Climate Policy Engagement Alignment’ assessment, under two distinct indicators:
In 2023, InfluenceMap’s methodology to assess corporate disclosures on climate policy engagement was formally updated in line with the Global Standard on Responsible Climate Lobbying and stakeholder input. The detailed methodology - as well as additional resources including best practice guidance and Marathon Petroleum's company profile - is accessible via the buttons on the right hand side of the page.
A summary of Marathon Petroleum's performance under this assessment is shown below, using the traffic-light assessment framework shown in the key. A more detailed breakdown is available below.
| Indicator | Score |
|---|---|
| Accuracy of Climate Policy Engagement Disclosure | No, does not meet criteria |
| Sub-Indicator | Score |
|---|---|
| Accuracy of Direct Climate Policy Engagement Disclosure | No, does not meet criteria |
| Accuracy of Indirect Climate Policy Engagement Disclosure | No, does not meet criteria |
A summary of Marathon Petroleum's performance under this assessment is shown below, using the traffic-light assessment framework shown in the key. A more detailed breakdown is available below.
The Review Score (0-100) assesses corporate performance against seven indicators, using the same traffic-light framework. A ‘Green’ scores 2 points, a ‘Yellow’ scores 1 point, and a ‘Red’ scores 0 points. This total is converted into a percentage from 0 to 100, calculated using the total number of points available (14). As such, only certain scores within the 0 to 100 range are possible under this methodology. A Review Score of 100 would indicate that a company has met all of the assessment criteria related to the review process.

This is an assessment of the accuracy of a company's reporting on its direct and indirect (via industry associations) climate policy engagement activities.
InfluenceMap utilizes its proprietary database to assess how corporate disclosures on climate policy positions and engagement activities compare to InfluenceMap's independent assessment of the companies' and industry associations' real-world climate policy engagement. In short, it assesses the extent to which the company has disclosed on all climate policy engagement identified by InfluenceMap's database.
The tables below provide: (1) a breakdown of Marathon Petroleum's performance under each sub-indicator, using the traffic-light assessment framework shown in the key; and (2) examples of leading practice by companies.
Has the company published an accurate account of its corporate climate policy positions and engagement activities (as compared to InfluenceMap’s database)?
Marathon's disclosure of its positions and engagement activities on climate policies is limited to top-line statements without reference to specific climate-related policies.
The company's website links to the US federal and state lobbyist registries, which include recent lobbying registrations on key legislation including the IRA's Nationwide Permitting Improvement Act. However, these disclosures offer limited details of company positions or policy outcomes sought in engagement activities. As a result, Marathon appears to have excluded key instances of engagement with specific climate proposals.
For example in its May 2024 comments to the Environmental Protection Agency (EPA), Marathon advocated against a stringent federal regulation of carbon emissions from existing gas power plants, and suggested that the EPA is acting beyond its legal boundary.
Additionally, in its February 2024 comments to the EPA on the Advanced Clean Cars II Regulation, it advocated for EPA to deny the California Air Resources Board's request for a waiver of preemption to implement the ACC II policy, which would phase-out internal combustion engines by 2035 in California and other participating states.
Enel has published a complete and accurate account of its positions and engagement activities on specific climate-related policies, and this is aligned with InfluenceMap's assessment of the company using its LobbyMap database. Enel included its climate advocacy activities, positions, and links to the company’s government consultation responses to specific climate-related policies from 2022-2024 in its 2023 Climate Policy Advocacy report, published April 2024. It also covered a range of regions in its disclosure, including Global, Europe, North & South America, Africa, and the Asia Pacific.
BP partially met the assessment criteria under this indicator, as it excluded material evidence of climate policy engagement. However, BP’s ‘Advocacy Activities’ webpage provides a clear and detailed disclosure of the company’s climate policy engagement, with filters for jurisdiction; date; and topic, including links to relevant consultation responses. It also contains sorting options for most recent, and most relevant.
Has the company published an accurate account of the climate policy positions and engagement activities of the industry associations of which it is a member (as compared to InfluenceMap’s database)?
Marathon has provided a near-complete list of its trade association memberships, but has limited the disclosure to top-line climate statements without reference to specific climate policies. Marathon has therefore excluded key instances of engagement with specific climate-related policies by its industry associations.
For example, in a June 2025 letter to Senate Majority Leader Mike Johnson, the National Association of Manufacturers advocated for the passage of the 2025 budget reconciliation bill, which proposes to repeal or rapidly phase out many of the Inflation Reduction Act's climate incentives and facilitates the buildout of fossil fuel infrastructure.
The company also does not disclose its membership to the International Air Transport Association (IATA) and the Consumer Energy Alliance. Marathon has added a new '2024' disclosure under the 'Trade Association Participation' section of the 'Political Engagement' webpage on its corporate website, but the link appears to be broken. InfluenceMap’s assessment was therefore based on its most recent trade association disclosure from 2024. As this disclosure is over a year out of date, one point has been deducted from its score.
See Appendix A below for details of the company's industry association memberships.
Unilever has published a complete and accurate account of its industry associations' positions and engagement activities on specific climate-related policies. In its March 2024 industry association review, the company attached LobbyMap profile links to each association’s assessment. Iberdrola published a largely complete and accurate of its industry associations' positions and engagement activities on specific climate-related policies.
Iberdrola and its North American subsidiary Avangrid both disclosed the climate policy engagement activities of their industry associations in their respective industry association climate lobbying reviews.
Marathon has published one review to date in 2021.
However, company reviews published more than two years prior to the end of InfluenceMap’s data collection period for the Climate Action 100+ Net Zero Company Benchmark 2024 assessments - i.e. August 1st 2024 - will not be included in the updated review assessments.
As such, Marathon's 2021 disclosure is not included in the review assessments.
Yes, meets criteria
Partial, meets some criteria
No, does not meet criteria
The table below provides a ranking of Marathon Petroleum's industry associations currently covered by InfluenceMap’s database by Performance Band, i.e. a full measure of a company’s climate policy engagement, accounting for both its own engagement and that of its industry associations. Detailed profiles for all industry associations can be explored via the links in the table.
Industry associations are categorized by InfluenceMap as having climate policy engagement that is aligned, partially misaligned or misaligned with delivering the 1.5°C goal of the Paris Agreement by Performance Band:
The ranking table below is updated automatically on a continual basis as: (1) new evidence is collected for the industry associations; (2) new industry associations are added to the company profile; (3) industry associations are removed from the company profile, e.g. if the company leaves the association.
As such, the industry associations and/or scores in the ranking table below may differ from the findings in Identify & Assess (Indirect) above, which was written on the date of assessment. See the top of this page for the date of assessment.
| Industry Association | InfluenceMap Performance Band | InfluenceMap Assessment |
|---|---|---|
| International Air Transport Association (IATA) | D | Misaligned |
| Western States Petroleum Association (WSPA) | E | Misaligned |
| Consumer Energy Alliance | E- | Misaligned |
| American Petroleum Institute (API) | E- | Misaligned |
| American Fuel & Petrochemical Manufacturers (AFPM) | E- | Misaligned |
| Texas Oil & Gas Association (TXOGA) | F | Misaligned |
