Our league table names greenest supermarkets

Published: 9 November 2009

Some UK supermarkets are greening up their act and doing more to help customers shop green but others are lagging well behind according to new mystery shopping exercise by Consumer Focus.

It found that the gap between the best and worst performing supermarkets has got wider since the first survey in 2006. Sainsbury’s and M&S made the biggest leap by achieving the first ever overall ‘A’ (excellent) score. They were followed by Waitrose, which retained a ‘B’ grade. Other supermarkets such as Morrisons showed improvement over the course of the surveys; Tesco showed no progress since 2007 and Asda moved down the ratings.

The survey also found some good green practices among the high street chains. The discounters Aldi and Lidl, surveyed for the first time, were the only two supermarkets to have closed doors on all freezers, thereby helping to conserve energy. The co-op was found to be selling the highest proportion of fairly traded products among its own brand products than any of its rivals.

The UK’s top nine supermarket chains were ranked on sustainability measures such as their offerings of UK in-season fruit and vegetables, organics, higher welfare meat and eggs and sustainably sourced fish. The survey looked not just at availability in the store but also how clearly these products were displayed and promoted to consumers in-store. The supermarkets were also rated on how much they encourage recycling.

Lucy Yates, sustainability expert at Consumer Focus, said: ‘We challenge all supermarkets to follow in the footsteps of their better rivals and help their customers – whatever their budget, to shop green. This means, helping consumers, for example, spot and buy UK seasonal produce such as spinach and courgettes through money off promotions or recipe ideas.

‘Shopping green should not be hard. Our survey shows that when a grocer has the will to respond to consumer pressure on green issues, this works through to the shop floor. Saying you have a sustainable fish sourcing policy is not enough – consumers must be able to find sustainable fish on the shelves’.

Consumer Focus is calling on all supermarkets to respond to consumer pressure and make their sustainable policies visible in the store. If supermarkets are serious about sustainability, they should stock a high proportion of green products and signpost sustainable issues at all points of customer contact, whether in the store, their website or through their helpline to help customers make green choices.
