On the second anniversary of M&S’s Plan A launch, the retailer this week upped the green ante with the launch of the Plan A Way to Save.

M&S said it could save its customers a “green grand” if they followed money-saving tips advertised instore and online, and on new clothing labels.

The advice includes reducing food waste by keeping fruit in the fridge and washing clothes at lower temperatures. “Becoming greener needn’t be difficult, expensive, or time-consuming and in fact our green advice could save households a thousand pounds,” said chairman Sir Stuart Rose.

M&S said it had worked with the Energy Saving Trust and Wrap to create The Plan A Way to Save, which builds on other M&S initiatives such as Wash at 30ºC and The Oxfam Clothes Exchange.

“We know some businesses are wondering if they can still afford to focus on the environment and ethical issues,” said Sir Stuart. “From a business perspective we can’t afford not to, while climate change won’t wait for the economy. Plan A was developed to address important environmental and social issues but in many areas of our business it’s driving efficiency savings.

“We’re pleased to be sharing some of what we have learnt so customers can benefit, too.”
