To quote Jeff Immelt, the CEO of GE, "We think green means green." And we ain't the only ones. Venture capitalists are quickly embracing this mantra as they adapt to a new market in which environmental responsibility is increasingly a valued commodity. Investments in North American companies developing green technologies rose 35% in 2005, says a new report by the Cleantech Venture Network. Of the $1.6 billion year-end total, $502 million was invested in the 4th quarter, comprising 10% of all North American venture capital investment during that three month time period.
