There are no strong indications that mixing FAME (Fatty Acid Methyl Ester) biodiesel up to 7 vol%2 and HVO (Hydrotreated Vegetable Oil) biodiesel up to 30 vol% will result in significant increase in harmful emissions by road traffic. This conclusion is based on the limited toxicological data suggesting low or negligible changes in the hazard profiles upon blending biodiesel.
