Leading in Sustainable Energy

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 March 2020, we became the first independent U.S. refiner to establish a companywide greenhouse gas 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. This is a positive step for our company and our industry, and we expect others will follow.

Methane Reduction

We established a 2025 goal to reduce methane emissions intensity from our natural gas business to 50% below 2016 levels. 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 2021, 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. Marathon Petroleum is the only company with fuels manufacturing as its primary business to earn the award, which 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 over 10% since 2015, and we have plans for additional reductions. In 2020, we adopted a formal “Focus on Water” program for our refineries to optimize our existing operations to further reduce water usage over time. Through the implementation of this program, we expect to reduce our freshwater withdrawal intensity by an additional 10% by 2030.
