Tony Greenham trained as a Chartered Accountant at PricewaterhouseCoopers before joining Barclays, and later Credit Suisse, as a corporate stockbroker. Disillusionment with investment banking during the dot com boom of the late 1990's, combined with a growing interest in sustainability, led him to an MSc in Environmental Assessment and Evaluation at London School of Economics. He joined the New Economics Foundation in 2010 to lead the Finance and Business research programme and also works with the Transition Towns movement - a network of community organisations pursuing practical sustainability projects on the ground. Tony is a sustainability advisor for Alliance Trust Investments and the Institute of Chartered Accountants in England and Wales. He is a regular media commentator and public speaker on sustainability and economic reform. Ben Lewis worked in the financial services sector for a decade with JLT Risk Solutions, R. J. Carvill and Hyperion Insurance Group. During this time he observed that companies often working in their specialist commercial niche had little opportunity to explore sustainable development in a meaningful way. He realised that too often the focus was on making existing practice 'right' rather than exploring new commercial practices that inherently address sustainability issues.
