This summer,UPS Inc.announced a historic,seven-year deal with Clean Energy Fuels Corp.The package delivery company said that through 2026,it will buy 170 million gallon equivalents of renewable natural gas(RNG).This is the biggest purchase of RNG in American history,and that makes sense,given the size of the UPS fleet and its commitment to reduce emissions-UPS has set a goal of alternative fuels constituting up to 40% of its ground fuel consumption by 2025.The company has 6,100 vehicles worldwide that now use either CNG or LNG.It also uses propane and has hybrid and electric vehicles.Bravo UPS;this is great news for the environment-experts say heavy-duty trucks and buses are the No.1 source of emissions in urban areas.But note that all of the gas fueling UPS trucks is not coming from wells drilled by the nation's natural gas producers.Instead,it is RNG,which is gas derived from methane emitted by landfills,dairy and hog farm waste and other renewable sources.Clean Energy Fuels,a company built on championing natural gas for vehicles,sells both gas from wells and from RNG.As of December 2018,the company served roughly 1,000 fleet customers operating some 47,000 natural gas vehicles(NGVs).To do this it owned,operated or supplied 530 natural gas fueling stations in 43 states and four provinces in Canada.
