WHO would have thought that saving the planet could be such a lucrative business? Al Gore, the former US vice-president turned environmental campaigner, has made more than £50m in just seven years from his books, speeches and shrewd investments in technology and green ventures.
There seems to be a lot of loot in proclaiming the Apocalypse.
Today Gore commands between £50,000 and £85,000 a speech, holds stock options in Google worth £15m and has made as much as £4m from advances on his book deals. He is also advising a US venture capital company on how to invest a $600m green technology fund.
