As with every other energy source, biofuels entail some risks and should be assessed over their entire lifecycle. This graphic, From seed and soil to end use, tracks the lifecycle of liquid biofuels for use in the transport sector – most of the available analysis has focused on this part of the sector, but it is increasingly recognised that biofuels are more than just transport fuels – from the moment land is converted for the purpose of growing biofuel crops, to the end use of the biofuel product in a vehicle. The graphic shows how various inputs to the production process create outputs with environmental and social impacts. Environmental and social issues related to the use of crops grown as biofuel feedstocks are similar to such issues raised in the agricultural sector as a whole, and are applicable to crops used for biomaterials, bioplastics and other products, too.
