Supermarket giant Tesco has confirmed it will run three-quarters of its distribution fleet on ‘greener’ biodiesel from next month.
It estimates that by using the B50 blend – 50 per cent ordinary diesel mixed with biofuel – it will cut its greenhouse gas emissions by more than 70,000 tonnes a year, equivalent to filling 15,000 swimming pools or 400 Royal Albert Halls.
Biofuels are renewable fuels made from agricultural crops and blended with standard diesel or petrol to deliver a reduction in emissions.
Tesco said it had already ensured biofuel blends were stocked on its petrol forecourts, resulting in the reduction of a similar level of carbon dioxide emissions to the distribution initiative.
The retailer has 2,000 lorries responsible for transporting goods to 754 stores and 716 smaller Express outlets.
Tesco Chief Executive Sir Terry Leahy described the move as an ‘extraordinary change’ for the supermarket giant.
The retail giant also recently opened a new supermarket featuring wind turbines to power the checkouts and rainwater to wash the home delivery vans.
The 50,000 sq ft store in Wick, north Scotland, is expected to cut by 50 per cent the carbon footprint left by other supermarkets of a similar size.
