RNG is biogas formed by the decomposition of organic matter, such as methane, that has been processed to pipeline-quality standards. It’s fully interchangeable with conventional natural gas, and can be used in natural gas-fuelled industries and vehicles as compressed natural gas (CNG) or liquified natural gas (LNG). When used as a vehicle fuel, RNG provides a substantial environmental benefit; 85% reduction of C02 emissions relative to diesel fuel.
