Game-changing emissions from renewable natural gas: In the past five years, renewable natural gas (RNG) captured from landfills, dairy farms and wastewater plants has gone from a niche fuel to providing over 35% of NGV fueling nationally and over 60% of NGV fueling in California – and these figures are expected to continue to rise. Like other forms of renewable energy, RNG provides ultra-low lifecycle greenhouse emissions, with reductions of 70% to 130% compared with gasoline.
