Climate change related businesses, like energy efficiency firms, saw worldwide revenues grow 75% in 2008, and could exceed $2,000,000,000,000 US by 2020. The Stern Review in 2006 expected such revenue to grow to $500,000,000,000 by 2050, so growth is proceeding well ahead of this estimate. Energy efficiency was the fastest-growing sector, according to a report from HSBC Global Research, with carbon finance following at 24%. (Sourc e: Reuters, September 18, 2009)
