Study suggests current levels of methane leakage would result in numerous decades of more rapid climate change from a shift to natural gas vehicles

Green Car Congress

After 150 years, a CNG fleet would have produced about 10% less cumulative radiative forcing than a gasoline fleet: a benefit equivalent to a fuel economy improvement of 3 mpg in a 30 mpg fleet. CNG vehicles fare even worse in comparison to heavy-duty diesel vehicles. Alvarez, Stephen W. Pacala, James J. Winebrake, William L.
