So this is the Kyoto Protocol in action: A marginally-economical chemical factory in an industrial superpower finally installs 1970s-era technology to clean up its act, and as a result makes 30 times more money by selling “carbon credits” to fight global warming than it makes by selling chemicals. This isn’t a last-ditch effort to upgrade Outer Mongolia—this is a French factory in South Korea. From the WSJ today: The company, Rhodia SA, manufactures hundreds of tons a day of adipic acid, an ingredient in nylon, at its factory here. But the real money is in what it doesn’t make. The payday, which could amount to more than $1 billion over seven years, comes from destroying nitrous oxide, or laughing gas, an unwanted byproduct and potent greenhouse gas. It’s Rhodia’s single most profitable business world-wide. Last year, destroying nitrous oxide here and at a similar plant in Brazil generated €189 million ($300.5 million) in sales of pollution “credits.” […] The Rhodia factory in [South Korea] alone is slated to bring in more money, under the U.N.-administered program, than all the clean-air projects currently registered on the continent of Africa.
