ASDA is the least environmentally friendly of all the major supermarkets, a new study has found.
The sustainability gap between the best and worst performing supermarkets is growing, according to Consumer Focus.
Sainsbury’s and Marks & Spencer made the biggest leaps by achieving the first ever overall “excellent” scores.
But Tesco showed no progress since 2007, while Asda moved down ratings to the foot of the table alongside Aldi and Lidl.
An Asda spokesman said: “In this report they have walked around one of our shops then made sweeping statements on our overall corporate policy.”
