Asda is investing in two new bio-liquefied natural gas (bio-LNG) – a renewable fuel made from organic waste – refuelling stations in a bid to reduce its wider carbon emissions.

The supermarket giant is working with commercial vehicle fuel producer Gasrec on its new refuelling facilities in Warrington and Dartford, bringing its total number of operational bio-LNG stations to 13.

Asda currently operates over 780 vehicles, making it the owner of the largest fleet of LNG fuelled trucks in the UK.

The grocery retailer’s shift comes as it attempts to speed up its wider goal of decarbonising and achieving net zero operations, which it is currently on target to hit by 2040.

Asda central fleet operations manager John Rogerson said: “LNG trucks are currently the leading alternative fuel option for operators like ourselves and with over 780 LNG vehicles, we operate the largest fleet of LNG fuelled trucks in the UK.

“Our continued investment in a UK-wide LNG distribution network forms an essential part of our objective to reduce overall carbon emissions across our operations, and towards building a sustainable business for the future.”

Asda revealed earlier this year that it had reduced operational carbon emissions last year by 41% agaist 2015 levels, with a target to achieve a 50% reduction by 2025.

Last month, the supermarket launched a new sustainability-linked enhancement to its Supply Chain Finance scheme in partnership with HSBC UK.
