Tesco have previously admitted using Palm oil in their biofuels - as this blog has noted before this is associated with a number of serious problems including large scale deforestation, adding to climate change and human rights abuses in Indonesia.
Tesco have said they ask their suppliers to provide a sustainability statement however apparently despite requests for a copy of this it has never been forthcoming.
Kevin Lister, a Nailsworth campaigner has been seeking answers - can Tesco now demonstrate responsibly sourced biofuels? Will it remove it from other products? See his latest letter to Tesco here, a letter to The Times here and a link the recent documentary on the Community Channel, 'Lost in Palm Oil'.
