Better Health for All
-40
Marathon Petroleum's core business of oil and gas refining causes severe, widespread health damage, with products having no redeeming health benefits. Operations have led to thousands of pounds of hazardous chemical releases, including benzene and sulfur dioxide, from incidents like the August 2023 Garyville refinery fire, which forced community evacuations.
1
The company has incurred over $1.29 billion in air pollution violations
2
and $1.45 billion in total environment-related penalties.
3
Its safety record is poor, with at least seven fires/explosions at one refinery in 2022-2023,
4
20 alleged breakdowns,
5
and deficient fire suppression systems.
6
EPA inspectors faulted Marathon's safety processes and communication,
7
and alleged failures to keep up with inspections.
8
While the company reports a 64% reduction in criteria pollutant emissions since 2000
9
and an 18% reduction in greenhouse gas emissions intensity since 2014,
10
and invests in renewable diesel production,
11
these efforts do not offset the major health-harming externalities. Marathon Petroleum offers comprehensive internal mental health programs for employees, including 21 workshops in 2022,
12
campaigns, and an Employee Assistance Program.
13
It also provides substantial internal preventative health measures, such as a $400 incentive for health assessments and physical exams,
14
health coaching, and an annual health and safety fair.
15
Externally, the company contributed $100,000 to an air quality monitoring fund in the Paso del Norte Air Basin, impacting 3 million residents and enhancing respiratory health awareness.
16
During the COVID-19 pandemic, Marathon Petroleum donated over 575,000 N95 masks
17
and its foundation contributed $1 million to the American Red Cross.

Fair Money & Economic Opportunity
-10
Marathon Petroleum Corporation (MPC) is an energy company and does not offer consumer lending or deposit services, nor does it operate financial service access points or provide debt products to consumers. Therefore, most financial inclusion and fair lending KPIs are not applicable. MPC co-hosted financial empowerment events in Detroit in 2022, offering financial education, free tax preparation, and financial wellness services.
1
These are considered occasional workshops with no reported reach or outcome tracking, aligning with a score of -70 for financial literacy initiatives. While MPC engages in community investments, supplier diversity initiatives, and general DEI programs, these do not align with the rubric's specific definitions for community finance reinvestment or a loan/insurance book. A consumer protection violation of $22.5 million in 2019 is noted
2
but is not explicitly tied to lending or financial inclusion for marginalized populations, thus not impacting the fair lending compliance KPI for a non-lender.
Fair Pay & Worker Respect
-60
Marathon Petroleum has faced 10 substantiated labor-law violations in the past three years (2023-2025), including a $7.2 million wage and hour violation in 2025
1
and nine safety violations in 2023 related to a fire at its Martinez refinery, which resulted in $188,000 in Cal/OSHA penalties.
2
The company has a record of repeat fatalities, with an employee dying in November 2022 at a Louisiana facility,
3
and two contract workers dying in 2023 at the Galveston Bay Refinery (one from electric shock, one from an explosion).
4
Multiple explosions and fires have led to OSHA fines, including incidents in February and October 2022 at a Louisiana facility.
5
In 2021, the company removed its safety performance index from employee bonus calculations.

Fair Trade & Ethical Sourcing
0
No specific quantitative data was provided in the articles to assess Marathon Petroleum Corp against the defined KPIs for Fair Trade & Ethical Sourcing. While the company has initiatives such as training nearly 800 employees to identify and report human trafficking through a partnership with Truckers Against Trafficking (launched in 2023), and has a Supplier Code of Conduct that prohibits child labor and expects compliance with ethical sourcing, including conflict minerals, the articles do not provide percentages for fair-trade certified spend, audit frequencies, number of substantiated forced/child labor incidents, traceability coverage, median remediation speed, or the percentage of contracts with ethical clauses. Dollar amounts for supplier diversity spend were provided ($795 million in 2023, up from $277 million in 2020), but not as a percentage of the total procurement budget, which is required by the rubric.

Respect for Cultures & Communities
-50
A Marathon Petroleum subsidiary engaged in unpermitted pipeline operations through Native American lands, leading to a lawsuit by tribal members in 2018.
1
This resulted in a BIA order for the company to cease operations and pay $187 million for damages, indicating a lack of Free, Prior, and Informed Consent (FPIC) from affected communities for these operations.
2
Furthermore, Marathon Petroleum reached a $241.5 million settlement for Clean Air Act violations at its North Dakota facilities on the Fort Berthold Indian Reservation, which included a $64.5 million civil penalty and a $177 million investment in environmental upgrades to address impacts on local indigenous communities.
