The conversions of our Dickinson, North Dakota, and Martinez, California, refineries from petroleum processing to renewable diesel production are part of our broader commitment to Leading in Sustainable Energy – from lowering the carbon intensity of our operations and products, improving energy efficiency and conserving natural resources, to increasing renewable fuels production and deploying advanced technologies. Below are just a few examples of our sustainability practices focused on environmental stewardship.

Greenhouse Gas Reduction

In 2022, we were the first independent U.S. refiner to establish a 2030 target to reduce absolute Scope 3 - Category 11 greenhouse gas (GHG) emissions by 15% below 2019 levels. Our Scope 3 target covers “Category 11: Use of Sold Products,” for products manufactured at our refineries.

Since 2020, we have had a companywide Scope 1 and 2 GHG emissions intensity reduction target. Achieving this ambitious target would result in a 30% reduction in carbon emissions from our manufacturing processes below 2014 levels by 2030. We’ve linked achievement of the goal to our executive and employee compensation programs.

Methane Reduction

We expanded our target to reduce methane emissions intensity from our natural gas business to 75% below 2016 levels by 2030. This expanded target builds on our target of a 50% reduction by 2025. This is an important initiative to ensure that natural gas provides the most climate benefits as it displaces coal for electricity generation.

Energy Efficiency

In 2022, the U.S. Environmental Protection Agency (EPA) recognized Marathon Petroleum with the ENERGY STAR® Partner of the Year—Sustained Excellence Award, the highest honor among ENERGY STAR awards. The award recognizes us for sustained, top-tier energy efficiency and excellent environmental compliance. Since the ENERGY STAR program began recognizing petroleum refineries, our facilities have earned more of the ENERGY STAR awards than all other refineries in the nation combined.

Water-Use Reduction

Through a variety of innovations at our refineries, we have reduced our freshwater withdrawal intensity by 15% since 2016, and we have plans for additional reductions. We adopted a formal “Focus on Water” program for our refineries to optimize our existing operations to further reduce water usage over time. Each refinery has designated engineers who serve as water coordinators, each has established baselines for assessing their water use, and each maintains robust transparency on how water is used through the use of standardized water monitoring and reporting.
