Natural gas vehicles powered with Renewable Natural Gas (RNG) are amongst the cleanest vehicles on our roads. RNG is produced through anaerobic digestion of manure and food, municipal, and solid waste. It is sourced from dairy farms, waste treatment facilities, and landfills. Waste that would normally decompose and produce fugitive methane emissions that are 25 times more potent than CO2, is instead processed into a carbon-negative fuel and delivered to vehicles as Compressed Natural Gas.
In the heavy-duty segment, CNG is a sure-thing alternative to diesel. Retail CNG has, on average for the past decade, been more than a dollar less per gallon than retail diesel, and because all RNG is produced domestically, has less of the volatility that diesel does.
