UK supermarket chain Aldi is set to convert over 30% of its fleet of owned heavy goods vehicles (HGVs) to operate on hydrotreated vegetable oil (HVO) fuels, as part of its long-term sustainability goals.

The transition involves the conversion of more than 160 HGVs based at the retailer's distribution centres in Cardiff, Swindon, and Neston.

This move is expected to reduce the retailer’s carbon footprint by an estimated 15,432tpa of CO₂e.

HVO fuel is a renewable diesel alternative that can reduce greenhouse gas emissions against conventional diesel.

Once implemented in Aldi’s entire fleet, comprising more than 550 HGVs, the initiative could potentially eliminate an additional 55,130tpa of CO₂e.  

Aldi national sustainability director Liz Fox said: “Switching to HVO fuels on our lorry fleet aligns with our long-term sustainability goals and reflects our commitment to reducing our carbon emissions.

“We are always looking for ways to continue our efforts to drive positive change across the business and this move in particular is a significant milestone for Aldi.”

This environmental push follows Aldi's trial of an all-electric refrigerated trailer in April 2022, which is designed to convert kinetic energy into electricity for powering onboard batteries. 

Last week, a report from consumer group Which? recognised the retailer as the UK's cheapest supermarket chain for the second consecutive month in July 2024.

Reinforcing its commitment to affordability, Aldi pledged to continue cutting prices this year to maintain its status as one of the UK's most cost-effective grocers.
