Marks & Spencer (M&S) has bagged a “triple” award for cutting carbon, water use and waste.
It is the first retailer to notch up all three awards from the certification group Carbon Trust.
M&S said it has sent zero waste to landfill and become carbon neutral since launching its Plan A green programme.
The supermarket said it has cut energy use in stores, offices and warehouses by 31% and slashed store refrigerant’s carbon emissions by 60% (compared to 2006/7 levels).
It used two billion fewer single-use carrier bags in its food halls and has tackled water-use in its stores and supply chain.
Clem Constantine, Director of Property at M&S said: “There’s a clear business case for managing and reducing our own impact on the environment. It saves money, helps us become more efficient and better prepares M&S for the future.”
