UP, Progress Rail to use biodiesel fuel to cut GHG emissions

Union Pacific Railroad locomotives will be getting a boost of biodiesel fuel under an updated fuel recommendation by Progress Rail.

The company has approved the use of up to 20% biodiesel blend in specific EMD locomotive series operated by UP. Previously, the locomotives were approved to operate at 5%.

The updated fuel recommendation comes after testing high-horsepower locomotives, used for hauling freight long distances, and monitoring performance for things such as fuel consumption, as well as impact on engine oil and fuel filters. Progress Rail is currently undergoing additional testing and development, UP and Progress Rail officials said in a press release.

"Union Pacific is dedicated to reducing its carbon footprint, and this is another step toward achieving our long-term goal to reduce absolute scope 1 and 2 greenhouse gas (GHG) emissions 26% by 2030," said UP Executive Vice President and Chief Human Resource Officer Beth Whited, who oversees the railroad's environmental, social and governance-related efforts.

Progress Rail is "committed to offering sustainable solutions by providing products that facilitate fuel transition, increase operational efficiency, and reduce emissions," said Progress Rail President and Chief Executive Officer Marty Haycraft. “Through continually investing in new products, technologies, and services, we offer a wide range of fuel flexibility, making a meaningful, positive impact on the environment and supporting our customers in achieving their GHG reduction goals.”
