GREEN RANKING FOR 2009
Ranking: 6
Worth: £14.4bn
Green investment: Natural energy

The mayor of New York City, Michael Bloomberg, made his fortune from the traders’ terminals and platforms that bear his name. As mayor he has promoted a green agenda for New York. He has enacted a plan called PlaNYC: A Greener, Greater New York to fight global warming, protect the environment and prepare the city for the extra 1m people who are expected to be living there by the year 2030. Bloomberg’s vision doesn’t stop there. He wants New York to start generating its own green power by using solar panels, harnessing river tides and even placing wind turbines on top of city bridges and skyscrapers. Forbes in its October 2008 list of the 400 richest Americans reckoned he is easily worth £14.4 billion.
