The use of biomethane as a transportation fuel has increased by 291% in the US since 2015, according to recent figures.

Natural Gas Vehicles for America (NGVAmerica) and the Coalition for Renewable Natural Gas (RNG Coalition) said RNG, which is captured above ground from organic material in agricultural, wastewater, landfill or food waste, produces carbon-neutral and even carbon-negative results when fuelling on-road vehicles such as short-haul and long haul trucks, transit buses and refuse and recycling collection vehicles. 39% of all on-road fuel used in natural gas vehicles in 2019 was renewable natural gas (RNG).

The organisations say RNG fuel has the lowest energy economy ratio (EER)-adjusted carbon intensity of any on-road motor fuel, as low as -400.1. Over the last five years, RNG (biomethane) use as a transportation fuel has increased by 291%, displacing around 7.5 million tonnes of carbon dioxide equivalent (CO2e). NGVAmerica and the RNG Coalition report that in 2019, a total of 717 million gallons of natural gas were used as a motor fuel. Of that, 277 million gallons were renewable.

Dan Gage, president of NGVAmerica, said: "RNG-fuelled vehicles are the most immediate and cost-effective heavy-duty option when seeking to combat climate change and clean our air. Respiratory health depends on clean air, and natural gas-fuelled vehicles provide a proven, affordable, and easily scalable zero-emission equivalent solution for commercial deployment today."

"RNG supply is growing," commented Johannes Escudero, CEO of the RNG Coalition. "With 110 RNG production facilities transforming waste into fuel, and another 100 facilities on the way, we are increasingly able to offer consumers the opportunity to decarbonise with RNG - the cleanest of any fuel available today."
