There is lots going on in China with cleantech, greentech, and other semantic manifestations of environmentally sustainable businesses. Wind and solar power are two that spring to mind as sectors in which I have met many people in recent months. Especially in the energy sector, China has lots of untapped potential for greener forms of fuel. But I'm stating the obvious.

Yesterday I finagled entry into the cocktail reception for the Investor Summit on Climate Risk being held at the United Nations in New York. Nobel's Al Gore, AFL-CIO's John Sweeney, and Ceres' Mindy Lubber presented at this one-day conference co-hosted by the UN Foundation and Ceres.

China is moving towards a cleantech/greentech investment bubble. It reminds me of 1999 when investors stormed through Asia more intent on hedging bets on dubious revenue models than doing good due diligence. But the great thing about bubbles is there is always a great need for information, so we are looking at ways to add some of these niche sectors onto some of our Chinese-language media brands in the coming months.
