Aldi plans to introduce fridge doors across its stores to save the equivalent of more than 2,000 tonnes of carbon dioxide emissions a year.
The project, which follows a trial on a limited number of its shops, is forecast to reduce each store’s energy consumption by approximately 20%.
That translates to carbon emissions saving of up to 20 tonnes per store every year.
Mary Dunn, Managing Director of Corporate Responsibility at Aldi UK, said: “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.”
Aldi said it has reduced its carbon footprint by more than 55% since 2012 through a string of measures including solar panel installations, low carbon fleet and 100% green electricity.
