2010 greentech investment numbers are out, and it was a good year — compared to 2009’s disappointing one. Global venture investment into green technologies stood at $7.77 billion last year,up 28 percent from 2009’s $6.1 billion, according to figures from the Cleantech Group this morning. North America led the world with $5.28 billion raised — more than 2009’s $3.65 billion, though less than the $6.25 billion raised in the go-go year of 2008. European green VC kept sliding, however, with only $1.62 billion raised in 2010, down from $1.75 billion in 2009 and $1.84 billion in 2008. Asia’s VC investment grew to $771 million last year, up from $655 million in 2009 and $620 million in 2008 — not impressive in its own right. But in terms of green IPOs, it was China that dominated in 2010, with eight of the 10 biggest public offerings for the year garnering $9.79 billion, or two-thirds of global capital raised. Most of those companies weren’t venture-backed firms, as compared to many U.S. greentech IPOs of the year, which drew a combined $4.06 billion. I’ll have more details from this and other 2010 greentech reports for you in next week’s weekly update — stay tuned.
