Marathon Petroleum Achievements in ENERGY STAR® Program

As a five-time EPA ENERGY STAR Partner of the Year – Sustained Excellence Award recipient, we are an active participant in the program, sharing our strategies and successes with other industrial companies.

The Partner of the Year – Sustained Excellence Award is the highest level of recognition in the EPA’s ENERGY STAR program. To earn the award, companies must go above and beyond the criteria for Partner of the Year recognition by showing continuous improvement over time in organization-wide energy savings and environmental performance, demonstrating best practices and actively promoting the ENERGY STAR program.

MPC’s award recognizes its performance throughout 2023, which includes these achievements:

• Companywide greenhouse gas intensity decreased for the ninth consecutive year.

• The St. Paul Park, Minnesota, refinery completed a three-year project to reinforce insulation across the entire site, which is lowering energy consumption and anticipated to reduce carbon dioxide-equivalent emissions by nearly 16,000 metric tonnes per year.

• MPLX's Bluestone natural gas plant in Pennsylvania reduced its energy intensity by approximately 10% within just one year of establishing a baseline as part of the ENERGY STAR Challenge for Industry.

• Five MPC refineries received 2023 ENERGY STAR certifications, meaning their energy efficiency performance was in the top 25% of peer facilities across the country. Since the certification program began, MPC has earned more certifications than all other U.S. refining companies combined.

ENERGY STAR® Challenge for Industry 

The ENERGY STAR Challenge for Industry is a national call to action to improve the energy efficiency of America’s manufacturers by 10% or more. By taking the ENERGY STAR Challenge, manufacturing sites set a goal to reduce their energy intensity by 10% within five years.

MPLX’s Bluestone natural gas plant in Pennsylvania entered the ENERGY STAR Challenge for Industry and has reduced its energy intensity by approximately 12% within 24 months, with aspirations to reduce this energy intensity further. This reduction has avoided an estimated 50,000 tonnes of CO₂e emissions during the 24 months. Additionally, we have 10 MPLX terminals that have previously achieved the challenge.

To build on the success of Bluestone, additional MPLX gas processing facilities have been recently entered into the ENERGY STAR Challenge, namely the Houston, Pennsylvania, facility, which is the largest gas processing facility in Pennsylvania, and the Sherwood, West Virginia, facility, which is the largest gas processing facility in the United States. As the ENERGY STAR program becomes more established within our midstream operations, the intention is to expand it to additional facilities, which will further reduce company energy use.
