     I first met Richard Sandor around 10 years ago when discussions about creating a global carbon

market began. He's been extremely important to the development of the emissions-trading (排污权交易

)industry since its beginnings. As chief economist for the Chicago Board of Trade in the 1970s, he had

helped develop the financial futures (期货) market, and in the late 1980s and early 1990s he all but

invented cap-and-trade programs for sulfur dioxide (SO?) emissions, the pollutant that causes acid rain.

The methodology was simple: the government puts a cap, or an upper limit on SO? emissions and then

the market takes over, with companies that can economically reduce SO? on their own allowed to sell

emissions fights to those that can't. Doing the same thing with greenhouse emissions was the logical next

step, and from the 1992 Earth Summit on, Sandor was at the forefront of those efforts, launching the

Chicago and the European Climate Exchanges, where companies could meet to trade carbon.

     Sandor is a creator and a great promoter of new markets, and he has the vision, to create something

out of nothing. He doesn't just work at the level of theory, but encourages others to get involved. And

he's always been good at making money. He realized that if we built enthusiasm in a market for actually

valuing the reduction of carbon emissions-and the global carbon market is already worth more than

$30 billion-we'd remember for decades to come as a true pioneer-a man who used the power of

financial incentives (激励)as a force for change.
