The 2013 California Green Innovation Index, the 5th edition of this index, was released on March 28 by the non-profit group, Next10. It reports that California’s per capita emissions have dropped 17% since 1990, and 2% between 2009 and 2010 alone. Between 2010 and 2011, clean tech patent registrations in California increased by 26% (more than double the rate of the U.S. as a whole, and more than 5 times the global rate). In the special feature section on Jobs in the Core Clean Economy, the report shows that job creation was four times greater in the clean economy than in the economy as a whole from 2001 to 2011. Regional data are provided.
