Our guest this week is John Elkington, Chairman and Chief Pollinator of Volans. John was a very early pioneer of corporate responsibility and sustainable development; he was the creator of the 'triple bottom line' concept - people, planet, profit. He talks with Mel about how to nurture a new generation of leaders who want to do the right thing, the role of business in a sustainable future for the planet, and how a paradigm shift will be necessary, but painful.
