Supermarket giant Morrisons has come under fire for failing to do enough to help shoppers make "greener" choices.

The Bradford-based chain got the joint lowest rating out of eight top food chains surveyed in the National Consumer Council's Greening Supermarkets report. The study pinpointed Morrisons as the only company which does not offer reusable "bags for life".

Meanwhile Somerfield got a "poor" rating for its organic food range and its approach to recycling. None of the eight chains scored highly in the NCC's five survey areas: food transport, waste, nature-fish, nature-trees and sustainable farming.

The survey has prompted shoppers and councillors in Bradford to call for Morrisons and other chains to take green issues more seriously. Councillor Hawarun Hussain (Green, Shipley) said: "Its quite disappointing to hear that Morrisons, our local supermarket, is the only one not to offer bags for life."

She said that in Bangladesh carrier bags had been banned completely to help the environment. "If they can do it there, why not here?" she asked.

Coun Martin Love, leader of Bradford's Green group, said: "There is an awful lot that all supermarkets could be doing. Now Morrisons has been highlighted as the only one not offering reusable bags, they may decide it's a good marketing ploy to introduce them."

Coun Love added that supermarkets should source more goods locally to reduce food transport and cut costs.

A Morrisons spokesman said: "We have an ongoing programme to address sustainable behaviour and we are making positive progress in the areas covered by this report, as well as in others. We recognise the challenge ahead and are working hard to meet our environmental objectives and targets."

Waitrose came top of the pack with an overall B grade and Marks & Spencer and Sainsbury's came joint second with C scores.

Morrisons shopper Sarah Leach, of Cullingworth, said: "If other supermarkets can do it, why can't Morrisons?"

Jim Gledhill, of Great Horton, said: "We shop at Tesco where they have started using bags and packaging that are degradable."
