Biomethane/RNG is six times less pollutant than diesel, and Clean Energy knows it well. Pioneer in the use of RNG as a fuel for heavy transport in the USA, it currently has 600 refueling stations throughout the country and partnerships with major national distributors. The company has also invested in the agricultural sector, in projects for the production of biogas and biomethane/RNG to power agricultural vehicles. In addition, Amazon has asked Clean Energy to build 20 new gas stations to refuel its company fleet with biomethane/RNG.
