They may not be popular with Tescopoly, but Tescos are doing some interesting things on the environmental front. They have started selling petrol with 5% bioethanol at their petrol stations.

According to the renewable transport fuels obligation, the details of which are to be described in this year’s budget expected in March, 5% of all motor fuel must come from renewable sources by 2010. Government figures suggest that if bioethanol replaced 5% of petrol in the UK, it would have the environmental impact of taking a million cars off the road.

Of course, we could take a million or so cars off the roads as well.
