No 鈥楶lan B鈥 for high street store which says it will power all 500 stores using renewable energy within five years

Britain鈥檚 favourite high street store, Marks & Spencer, has announced a 拢200m plan to make the company carbon neutral within five years.

Chief executive Stuart Rose said the company would become 25% more energy efficient and all 500-plus M&S stores would be powered with 鈥済reen鈥 renewable energy.

This will include trialling the use of 鈥渁naerobic digestion鈥 - to create renewable energy generated by waste from our food halls, farms and factories

Rose said the proposals were called 鈥淧lan A鈥 because there is no 鈥淧lan B鈥. He said: 鈥淭his is a deliberately ambitious and, in some areas, difficult plan. We don't have all the answers but we are determined to work with our suppliers, partners and Government to make this happen. Doing anything less is not an option.鈥

The plan was produced with the help of Jonathan Porritt, chair of the Sustainable Development Commission. He said M&S had set a new benchmark for others to follow. He said: 鈥淚t raises the bar for everyone else - not just retailers, but businesses in every sector.鈥
