Westport Commends Study by West Virginia University


Westport Fuel Systems commended the publication of a study by West Virginia University scientists at the Center for Alternative Fuels, Engines and Emissions (CAFEE) quantifying methane emissions from heavy-duty natural gas-powered vehicles and refueling stations.

CAFEE scientists collaborated on the study with the Environmental Defense Fund and a group of global natural gas industry leaders including the American Gas Association, Chart Industries, Clean Energy, Cummins, Cummins Westport, International Council on Clean Transportation, PepsiCo, Shell, Volvo Group, Waste Management, and Westport Fuel Systems. The study was published online by the journal Environmental Science & Technology and the results greatly expand on the very limited data on methane emissions from natural gas vehicles.

“This study offers a critical baseline by which ongoing product and technology enhancements can be measured, as it represents the first significant effort to quantify actual in-use methane emissions from natural gas filling stations and heavy-duty vehicles”, said Karen Hamberg, Vice-President of Natural Gas Industry and Government Relations. “Natural gas-fueled vehicles are expected to play a greater role in future transportation to meet the global regulatory trend for more stringent greenhouse gas emission (GHG) reductions.”
