Ken Livingstone has chosen Andrew Morrison, regional director at B&Q as retail champion in a new programme that will celebrate the role Londoners can play in creating a more sustainable city.
The 'London Leaders' programme was launched with the announcement of 15 individuals from all walks of London life.
It is hoped that these leaders will act as an inspiration to other Londoners and encourage them to take action in their own communities.
At the launch each of the leaders signed a pledge committing themselves to a key sustainability campaign over the coming year.
The appointees also include an urban regeneration champion who will be persuading city institutions to adopt 'living roofs', a vicar who is expanding a city farm programme and a director of a refugee support unit who wants to forge links between London refugee organisations.
Mr Morrison was selected following B&Q's climate change initiative, which gained a Big Tick in the Man Group International Climate Change Award category in June this year.
Mr Morrison said that it is B&Q's aim to get more sustainable products into the company's stores, raise the profile of sustainable products and practices and establish partnerships to generate more sustainable results in areas such as emission reductions.
"This will be done through a series of events in London B&Q stores promoting sustainable living, and developing partnerships with suppliers to source and develop more sustainable products," he added.
The London Leaders programme was developed by the London Sustainable Development Commission following an international research programme, which reviewed how other cities are embracing sustainability.
Over the next 12 months the 15 Leaders will undertake a variety of challenges that show 'sustainability in action' from grass roots through to the boardroom.
