UK retail giant Marks and Spencer (M&S) has launched its 2014 ‘Plan A’ report detailing its proposals for a sustainable business plan over the next six years.

Called Plan A 2020, the 100-commitment plan includes new commitments that M&S operations worldwide will be carbon neutral. In addition, the plan includes an energy efficiency target increased from 35% to 50% per square foot by 2023.

Highlights of the plan include a commitment to ensuring that 50% of the energy used in UK and Ireland stores comes from small-scale renewable sources by 2020.

Marc Bolland, Chief Executive of M&S, said: ‘Plan A is at the heart of our plans to become a sustainable, international, multi-channel retailer. It’s become a vital part of how we run our business and represents a better way of working that materially improves our customers’ and partners’ experience of M&S.’

M&S became the first retailer to receive the triple award of certification for achievements in carbon, water and waste reduction from the Carbon Trust.
