Those of us who drive modern cars with 'Common Rail' diesel engines (or the VW 'PD' engine) and Diesel Particulate Filters (DPFs) should be aware that using diesel fuel that contains more than 7% Biodiesel can cause very expensive damage to the engine. (7% Biodiesel is known as BS EN 590).
Having mandated DPFs for Euro V compliant vehicles, EU bureaucrats have also mandated the gradual increase of Biodiesel content over the coming years (Directive 2003/30/EC). B30 (30% Biodiesel) certainly isn't DPF compatible and obviously nor is 100% Biodiesel. Only the Soviet EU could dream up and implement two such incompatible mandates that are likely to cause problems for drivers and their wallets. I hope that the biofuel content of diesel (and petrol) is going to be labelled at the pumps so we know exactly what we are actually putting into our tanks!
