24 Oil Prophets Washington, D.C. – A new study published today said that switching from diesel to natural gas in heavy- duty trucks could worsen and accelerate negative climate impacts unless methane leakage can be lowered. The study also outlined the need for increased data and new policies to lower methane leakage in order for natural gas heavy duty trucks to have a possible environmental advantage over new and future clean diesel trucks. 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. The report concludes: "Our results show that under our reference case assumptions, reductions in CH4 (methane) losses to the atmosphere are needed to ensure net New Environmental Study Urges "Caution" for Policymakers Considering Replacing Clean Diesel Trucks With Natural Gas Vehicles Uncertainty Over Amount of Methane Emissions & Diesel Technology Efficiency Warrant Further Examination May 19, 2015 // Diesel Technology Forum
