M&S is now carbon neutral, becoming the first major UK retailer to reach this mark. The company said it now recycles 100 per cent of its waste, and has made all its offices, warehouses and delivery fleets carbon neutral.
M&S have reduced their energy usage by 28 per cent by using more efficient fridges, offsetting their carbon footprint, and recycling all their waste, using anaerobic digestors and composting.
Despite this progress, the company said it has failed to meet six of its targets, due to a decline in sales of organic food, and difficulties in supply chains, inhibiting their plan to convert 20m items of cloting to Fairtrade cotton and to convert all turkey, geese, duck and pork products to free range.
Marc Bolland, M&S chief executive, said: "I am proud of what we've achieved. We now have a better, greener and more ethical Marks & Spencer.
"Moving forward we will continue to engage customers in sustainable consumption, as we have with our Shwopping initiative, the first cradle to cradle clothes retailing business model.
"We remain as committed to Plan A as we have ever been. It is an essential part of our DNA and fundamental to our plans to become an international, multi-channel retailer."
