Under the Renewable Transport Fuel Obligation (RTFO), which came into effect on 15 April, transport fuel suppliers are required to report on the sustainability of any biofuels in respect of which they wish to earn renewable transport fuel certificates. Details of the reporting requirements are available via the Renewable Fuels Agency's website at http://www.dft.gov.uk/rfa.
The Government have set various targets to encourage transport fuel suppliers to source sustainable, low carbon biofuels. The Renewable Fuels Agency will report regularly on the performance of different transport fuel suppliers against these targets.
In parallel, the Government are pressing for EU-wide mandatory sustainability standards for all biofuels: these could be in place by April 2010.
