A biofuel is a gas, liquid, or solid from natural sources such as plants that is used as a fuel. Biofuels can be mixed with conventional fuels. COBUILD Advanced English Dictionary.
Most biofuel is derived from plants, either crops grown specifically for fuel use or material left over from plants harvested for other uses. Burning biofuel releases carbon dioxide to the atmosphere, just as burning any other fuel does.However, unlike fossil fuel, biofuel can be renewable and low in carbon intensity -- if it is derived from plants that are grown sustainably (with new growth continuously replacing harvested material). Biofuels can be low in carbon intensity (the net amount of carbon released to the atmosphere) - as long as uptake by other growing plants balances the carbon that is released in biofuel production and use.
