Biodiesel is derived from vegetable or animal oils, which are also used for a variety of other purposes, and is also available for import as a blend with conventional diesel fuel. The Department does not hold information on the volume of biodiesel feedstocks imported into the UK in each of the last five years, nor does the Department have estimates of quantities likely to be imported in each of the next five years.
When the Renewable Transport Fuel Obligation (RTFO) comes into effect in April 2008, transport fuel suppliers will be required to report on a monthly basis the feedstock from which their biofuels were produced and its country of origin.
