Biofuels come from organic products and are considered to be renewable fuels. Renewable fuels have the characteristic of lower CO2 emissions over their life cycle than conventional fossil fuels, a factor that depends directly on their origin, use, and how they are produced and distributed. During their combustion, these fuels emit approximately equal amounts of CO2 with their respective petroleum products.
Biofuels include bioethanol, biodiesel, biogas, biomethanol, oxydimethyl ether, synthetic biofuels, bio-hydrogen and pure vegetable oils.
