Werner Among First Group Of Carriers To Test RNG Through Cummins Engines

Werner Enterprises (Werner), a transportation and logistics provider, enhanced its sustainability efforts through testing and validating the 2023 X15N Cummins natural gas engine in its fleet. Werner is one of the few carriers that have started testing the newest engine technology with natural gas, with a goal to achieve a 55% reduction in carbon emissions by 2035. “As a top five truckload carrier in North America, we are committed to implementing sustainability initiatives creating long-lasting and industry-wide impacts,” said Werner’s Chair, President, and CEO Derek Leathers. “These vehicles can greatly reduce emissions when running on renewable natural gas [RNG] and we are eager and willing to help validate this new technology.”

RNG is a biogas that comes from a variety of sources, including municipal landfills, water purification facilities, and livestock farms and can be up to seven times cleaner toward carbon emissions than diesel. This technology is built on a global internal combustion engine (ICE) platform by Cummins and will be tested in the market through the Peterbilt Model 579. Cummins anticipates production of the X15N in 2024. “Testing the new X15N with Werner Enterprises is a natural step in our ever-evolving relationship with one of the nation’s largest truckload fleets as we continue to work together on new technologies,” said Puneet Jhawar, general manager of the Global Spark Ignited and Fuel Delivery System Business. “We are excited to put Cummins next generation natural gas-powertrain through the rigor of Werner’s structured testing and validation process to deliver a world-class product for our full production start in early 2024.”

“Werner Enterprises is an excellent business partner of Peterbilt, and this is an excellent example of working together on our joint commitment to environmental stewardship and sustainability,” said Jason Skoog, PACCAR Vice President and Peterbilt General Manager.
