Natural gas is an immediately available alternative to oil, with lower greenhouse gas emissions than any other hydrocarbon fuel and practically none of the pollutants (particulate matter and nitrogen oxides or NOx) that increasingly contaminate the air we breathe in areas with dense traffic. Vehicles fuelled by natural gas are quieter and more economical than vehicles powered by traditional fuels. The technology used in natural gas vehicles is mature and safe.
Gas as a vehicle fuel is available as Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) for cars, vans, buses and trucks, with many different models on the market today from established manufactures. LNG is furthermore becoming the fuel of choice for the shipping industry due to its low sulphur emissions.
Natural gas is mainly composed of methane (CH4), which is found in large amounts in nature: the global reserves of natural gas considerably exceed those of oil (>200 years). New discoveries are made regularly. Natural gas is extracted from underground gas fields, located at various depths.
Natural gas also offers important synergies with biomethane from waste and biomass or synthetic gas produced from wind and solar energy. When mixed with biomethane the already lower CO2 emissions from natural gas compared to traditional fuels are reduced even further.
