Lord Browne – Chief Executive BP (1995 – 2007)

He made his name and fortune in the oil industry and in the process became one of Britain's best known business leaders. John Browne was BP's boss for 12 years. He expanded and diversified one of the world’s fossil fuel giants. Now he's back in the thick of the energy debate backing a company eager to develop shale gas production in the UK. His career has been defined by the search for fossil fuels and economic sustainability. Can we have both?
