Direct Lobbying Transparency

Overall Assessment	Comment	Score
Comprehensive	Marathon Petroleum Corporation has demonstrated a comprehensive level of transparency in disclosing its climate lobbying activities. The company explicitly names specific climate policies it has engaged with, such as advocating for Sustainable Aviation Fuel (SAF) incentives, requesting the EPA to "correctly categorize renewable diesel," and supporting the recognition of canola oil as an approved renewable diesel feedstock under the Renewable Fuel Standard. It also highlights its involvement in the Renewable Fuel Standard Set process, advocating for GHG reductions and the recognition of regenerative farming and carbon capture practices. Regarding lobbying mechanisms, Marathon Petroleum provides detailed information, including direct engagement with policymakers like the EPA and Congress, participation in trade associations such as the American Petroleum Institute and the Advanced Biofuels Association, and grassroots activities that mobilize stakeholders to contact officials. The company also discloses its collaboration with alliances like the Leading in Gulf Coast Hydrogen Transition (LIGH2T) Hub and Appalachian Regional Clean Hydrogen Hub. Furthermore, Marathon Petroleum is explicit about the policy outcomes it seeks, such as advocating for "an economy-wide price on carbon" to drive emissions reductions, promoting incentives for SAF production, and supporting government investment in innovation through grants and tax incentives for Carbon Capture Utilization and Storage (CCUS) and hydrogen energy projects. These disclosures clearly articulate the specific legislative and regulatory changes the company aims to achieve, demonstrating a high level of transparency in its climate lobbying efforts.	4

Lobbying Governance

Overall Assessment	Comment	Score
Strong	Marathon Petroleum Corporation's disclosures present a mixed picture of its climate lobbying governance. While several pieces of evidence indicate only limited details – for example, noting that the company is "committed to conducting climate-related lobbying activities in alignment with the ambition of the Paris Agreement" without elaborating on specific mechanisms or naming responsible individuals – a more detailed account provides a clearer view of its processes. This stronger disclosure explains that the company has engaged with its trade associations to "communicate our lobbying expectations and our plans for ongoing evaluation and disclosure," and highlights that "on an annual basis, our senior management undertakes a review of trade association memberships" with oversight provided by its Board and Sustainability and Public Policy Committee. These elements suggest that, despite some gaps in explicit detail across various reports, Marathon Petroleum has established a defined structure for aligning both direct and indirect lobbying efforts with its climate objectives, indicating strong governance practices overall.	3
