A new study indicates that switching from diesel to natural gas in heavy-duty trucks could worsen and accelerate negative climate impacts unless methane leakage can be lowered. According to a press release from the Diesel Technology Forum:
The study – “Influence of Methane Emissions and Vehicle Efficiency on the Climate Implications of Heavy-Duty Natural Gas Trucks” - was conducted by scientists at the Environmental Defense Fund (EDF) and Columbia University’s Lenfest Center for Renewable Energy and published today in the journal Environmental Science and Technology ... “This new report puts into perspective the complexity involved in evaluating alternative fuels in the transportation sector, and the importance in understanding the full picture before rushing to judgment about the merits of one technology over another,” said Allen Schaeffer, the Executive Director of the Diesel Technology Forum.
