Mike Barry


Mike is a leader in sustainable change. One of the pioneers of green business in the corporate world he helped to develop, launch and implement Marks and Spencer’s ground-breaking sustainability programme, Plan A (because there is no Plan B for the one world we have). In ten years, Plan A delivered £750m of net business benefit and over the years won 230 awards.

During his time at M&S he helped evolve Plan A to become a change management programme designed to make sustainability ‘how M&S did business’. The business achieved zero-waste-to-landfill status, moved to 100% renewable electricity and achieved carbon neutrality across its global estate of stores, offices and warehouses.

He helped the business engage in some of the world’s leading collaboration platforms for sustainability such as the World Economic Forum, the Consumer Goods Forum and Business in the Community. His external leadership ensured that Plan A leadership and learning was leveraged into wider change throughout the global economy, including:

  • Inaugural winner of the Guardian Sustainable Business Innovator of the year in 2011 after a public vote; 
  • Co-chair of the Consumer Goods Forum (CGF) Sustainability Steering Group; 
  • Chair of the World Environment Centre; 
  • Member of Business in the Community’s Environmental Leadership team; 
  • Business Fellow at the Smith Centre Oxford University; 
  • Senior Associate Cambridge Institute for Sustainable Leadership
  • Ethical Corporation Honouree 2019
  • Trustee at Blueprint for Better Business

Having worked at an international level of business, with charities, with think tanks, and with start-ups he has a broad array of experience. He has proven the necessity of dialogue, trust and the willingness to develop engagement into wide ranging mutually beneficial partnerships. This is vital for the interconnected world we live in.

During his career he has shown exceptional drive, integrity and personal resilience throughout periods of management change, takeover battles and challenging trading. He has developed excellent leadership skills and has demonstrated his ambition and passion to build a more sustainable future.

Upon leaving M&S he formed mikebarryeco ltd in order to support organisations across society and the economy to deliver sustainable change.
