Has the green tech recovery stalled?
Global venture capital investment in green technology companies fell 30 percent, to $1.53 billion, in the third quarter of 2010, according to a preliminary report issued Friday by the Cleantech Group, a San Francisco-based research and consulting firm.
The amount invested in North America, Europe, China, India and Israel in the third quarter was also 11 percent below the year-ago quarter, when investment tanked amid the recession.
The numbers are striking, given that investment in green-tech start-ups soared in the first half of this year, surpassing records set in 2008 at the height of the clean technology boom.
“Much like we see globally, I think businesses and investors are grappling a little bit with a recovery that hasn’t yet taken off, and I think people are trying to figure out how quickly will the growth occur,” Sheeraz Haji, president of the Cleantech Group, said during a conference call Friday. “I think we’re seeing a little bit of the same in clean tech.”
California, an epicenter of green technology innovation, suffered a precipitous decline, with investment falling 61 percent.
Mr. Haji questioned whether uncertainty over the fate of California’s global warming law, known as A.B. 32, played a role in the falloff in investment. A measure on the November ballot, Proposition 23, would suspend A.B. 32 until the state unemployment rate falls to 5.5 percent for four consecutive quarters.
