22/04/2008 (IcWales, UK) - TESCO service station green fuel could make climate change worse rather than better, according to an investigation by Greenpeace.
The environmental campaigners found the chain sold one of the most environmentally damaging biodiesels, with 30% of biofuel in Tesco diesel from palm oil.
New government regulations came into force last week, obliging fuel suppliers to ensure that at least 2.5% of the petrol and diesel sold in Britain comes from crops.
The new law, designed to reduce carbon dioxide emissions, allows companies to comply by buying cheap palm oil from plantations created by chopping down rain forest.
But some scientists say that, rather than being an effective solution to climate change, biofuels contribute more greenhouse gases, through deforestation and the use of fertilisers, than they save.
Greenpeace campaigner Belin- da Fletcher said: “Palm oil is the leading cause of rain forest destruction in countries like Indonesia and this is proof the Govern- ment’s biofuels policy could make climate change worse.”
A Tesco spokeswoman said the Greenpeace report was “highly misleading”. She said Tesco biofuel supplier Greenergy were members of the Roundtable of Sustainable Palm Oil, and by the end of this year a rigorous audit would ensure than all fuel came from sustainable sources.
