Natural Gas Vehicles for America (NGVAmerica) and the Coalition for Renewable Natural Gas (RNG Coalition) announced that 39% of all on-road fuel used in natural gas vehicles in calendar year 2019 was renewable natural gas (RNG).
Captured above ground from organic material in agricultural, wastewater, landfill or food waste, RNG produces carbon-neutral and even carbon-negative results when fueling on-road vehicles such as short- and long-haul trucks, transit buses, and refuse and recycling collection vehicles. RNG fuel has the lowest EER-adjusted carbon intensity of any on-road motor fuel—as low as -400.
Over the last five years, RNG use as a transportation fuel has increased 291%, displacing close to 7.5 million tons of carbon dioxide equivalent (CO2e). NGVAmerica and RNG Coalition report that in 2019 a total of 717 million gallons (GGE) of natural gas were used as motor fuel. Of that, 277 million gallons (GGE) were renewable.
