The Consumer Focus Report “Green to the Core” says Asda’s green credentials have fallen to the same level as discount supermarkets Lidl and Aldi.
The supermarkets were judged on climate change, waste, recycling, sustainable fish and sustainable farming and given A, B, C, D, or E grade rating.
Asda was criticised for the low availability of seasonal UK produce, which the report says dropped 10% to 59% from 2007.
The government watchdog says that Sainsbury’s and Marks & Spencer have made the most improvement since the last report in 2007 and awarded both retailers “A-grades”, the first time the top score has been given.
The research claims that Tesco and Waitrose have made no progress since 2007 but Morrisons has improved each year since the report was first published in 2006.
The Co-Operative Group, Morrisons and Tesco were all awarded a C grade. Asda, Aldi and Lidl were awarded D grades, Waitrose maintained a B grade and M&S and Sainsbury’s were awarded A grades.
Sainsbury’s is set to reveal it plans to stop using F-gases to cool its fridges but will instead use carbon dioxide, which is less polluting.
