Our energy strategy centres around 3 basic principles:
1) Reduce the amount of energy we use within our global built environment
2) Source as much energy as possible from renewable, small-scale sources
3) Work with credible, innovative and world leading partners to offset any remaining carbon emissions we haven't already been able to nullify.
Since the initial launch of Plan A in 2007, we have been on a journey to transform our business to reduce our greenhouse gas emissions. We have achieved this through monitoring our energy use, giving each of our stores individual targets to achieve, pioneering new low carbon technologies and investing in energy efficient equipment.
We operate in accordance with an M&S Group wide Energy Policy and our energy management systems and processes in the UK and the Republic of Ireland are certified to ISO 50001: 2011 the international Energy Management Systems standard.
We source all our electricity in the UK and the Republic of Ireland from renewable sources. We are also making good progress generating renewable energy in our own estate - in 2015, M&S launched the largest single roof mounted solar panel array at our Castle Donnington warehouse; and in 2017 we launched M&S Energy Society, a community benefit society that generates renewable electricity from solar panels installed on 8 M&S stores. We continue to look for opportunities to build on our existing 16 solar PV sites and are developing a pipeline of opportunities for future development.
We try to make sure store retrofits and construction are as energy efficient as possible. We also aim to procure fixtures, fittings and equipment that meet best practice energy efficiency standards.
We believe we can make significant savings and improve performance through smarter staff engagement.
In the UK and the ROI we achieved a 47% improvement in energy efficiency between 2020/21 and 2007.
