My move from South Africa to the United Kingdom to begin a new phase of my career really began in August 2002, at the World Summit on Sustainable Development (WSSD, or Rio+5) in Johannesburg. I used the event as a climax for launching my new book: Beyond Reasonable Greed: Why Sustainable Business is a Much Better Idea! It was also where I officially told my team at KPMG that I would be leaving to do a PhD. And it was, by chance, where I met Polly Courtice, Director of the Cambridge Programme for Sustainability Leadership, who became (and remains) such a significant catalyst for my work in sustainable business.
