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

Pacala, Princeton University; James J. Chameides, Duke University; and Steven P. Hamburg, EDF—assessed the climate-forcing implications of three US-specific fuel-switching scenarios: from gasoline, diesel fuel, and coal to natural gas. CNG vehicles fare even worse in comparison to heavy-duty diesel vehicles.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

For comparison, they team estimated the RFS goal for cellulosic fuels to be equivalent to 1289 PJ. The climate-targeted scenarios included cellulosic biofuel substitution to reduce GHG from light duty transportation to 20% of the reference GHG. Renewable and nuclear electricity supply technologies are available today.
