Tesco, the UK's largest supermarket chain, has announced plans to run three quarters of its delivery fleet on biodiesel from January next year.

The retailer is the latest to look at ways of reducing the impact its business has on the UK environment. Tesco said it will run its 2,000 trucks and vans on a 50% biodiesel mix to cut the greenhouse gases they produce. Biofuels are gaining in popularity and are made from crops like wheat, and are often blended with petrol or diesel.

Ordinary cars can run on blends of 5% biofuel and 95% petrol, a blend that is becoming more widespread at service stations across the UK. Specially enabled biofuel cars, like the Ford Focus flex-fuel or the Saab Biopower, can run on a mix of 85% bioethanol and 15% petrol.
