International standards for guaranteeing that biofuels originate from environmentally sustainable sources moved a step closer yesterday after the Roundtable on Sustainable Biofuels (RSB) released draft guidelines.

The draft criteria, called Version Zero, set out 12 standards that biofuel producers must adhere to if they are to label their fuels as sustainable, including compliance with local laws, provision of evidence their fuel delivers reductions in carbon emissions compared with fossil fuels and does not adversely impact food supplies, and the adoption of measures to limit impacts on biodiversity, soil quality and water supplies.
