Renault has unveiled a diesel 2.0-litre Trafic and a 2.5-litre diesel Master capable of running on fuel containing 30 per cent biodiesel. Environmentally friendly biodiesel can be made from a wide variety of sources of renewable energy, including vegetable oil.Renault sees biofuels as one of the most efficient and economic ways of controlling CO2 emissions in the medium term as it is easy to fit this technology on volume production models. An engine running on 30 per cent biodiesel emits up to 20 per cent fewer CO2 emissions than a conventional diesel, depending on the biological source.
