Aldi is to install fridge doors as standard across its new stores and refurbishments in a bid to reduce emissions.
The discounter said the move would save the equivalent of over 2,000 tonnes of carbon emissions a year.
It follows a trial of the doors in which energy consumption across participating stores fell by around 20%. That equated to each store saving up to 20 tonnes of carbon emissions annually, according to Aldi.
It is the latest Aldi climate change initiative. Aldi says it has been carbon neutral since January 2019 and has reduced its carbon footprint by more than 55% since 2012 through a number of sustainability initiatives, including the use of solar panels, switching to 100% green electricity and investing in a greener fleet.
“We are always looking for new ways to minimise our carbon footprint, which is why all our stores already use 100% renewable electricity, and our new stores also utilise natural refrigerants and feature efficient LED lighting,” said Mary Dunn, Aldi UK MD of corporate responsibility.
“Introducing fridge doors is another step on that journey to reduce our energy consumption and we hope that customers enjoy the new, more sustainable shopping experience.”
