Since 2019, Marathon Petroleum's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have decreased by 23.17%, reflecting a declining long-term trend in Scope 2 emissions over time.ab
Compared to the previous year (2023), Marathon Petroleum's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Marathon Petroleum's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2024, Marathon Petroleum reported its Scope 2 emissions using the location-based method.a
In 2024, Marathon Petroleum reported 405,000,000 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2024 disclosure of Marathon Petroleum includes a breakdown across 1 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2023, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2024, Marathon Petroleum reported total Scope 3 emissions of 405,000,000 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 0% of these emissions originated from upstream activities such as purchased goods and capital goods, while 100% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Marathon Petroleum's Scope 3 emissionshave remained relatively stable, indicating that Marathon Petroleum's emissions have plateaued with no significant change in its value chain footprint.ab
Compared to the previous year (2023), Marathon Petroleum's Scope 3 emissions remained relatively stable, indicating that Marathon Petroleum's emissions have plateaued with no significant change in its value chain footprint.a
In 2024, Marathon Petroleum reported emissions for 1 out of the 15 Scope 3 categories defined by the GHG Protocol.a
The limited disclosure restricts visibility into specific emission sources across the company's value chain.
In 2024, the largest contributors to Marathon Petroleum's Scope 3 emissions were:a
In 2024, Marathon Petroleum reported Scope 1 greenhouse gas (GHG) emissions of 34,600,000 tCO₂e and total revenues of USD 138,864 millions. This translates into an emissions intensity of 249.16 tCO₂e per millions USD.a
In 2024, Marathon Petroleum reported a Scope 1 emissions intensity of 249.16 tCO₂e per millions USD. Compared to the peer group median of 228.43, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2024, Marathon Petroleum ranked 15 out of 23 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Marathon Petroleum is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2024, Marathon Petroleum reported a total carbon footprint of 445,900,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 1.39% increase compared to 2023, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Marathon Petroleum's total carbon footprint was Scope 3 emissions, accounting for 90.83% of the company's total carbon footprint, followed by Scope 1 emissions at 7.76%.a
