Liebreich created what is now known as Bloomberg New Energy Finance in 2004 as a specialist provider of information on clean energy for the growing industrial interest in the area. As the FT’s 2011 profile describes, Liebreich built New Energy Finance from a small team largely made up of interns to a business sold to Bloomberg in 2009 for an estimated £45 million. Via physics and engineering at Cambridge, Harvard Business School, McKinsey and a stint on the British Ski Team, Liebreich has an impressive CV. There have been rumours recently that he might run as conservative Mayor of London. Whether he is well enough known outside of the climate bubble to bid for one of the most powerful political posts in Europe is to be seen, but he is widely respected for his imagination, drive and clarity by many on the political left as well as right. He is also active on Twitter @MLiebreich.
