Under the Montreal Protocol, the developed nations agreed to phase out production of freon for refrigerant use by 2010. We put in declining allocations: nobody can make more this year than last year. Canada's imports and manufacture of freon actually stopped in 2002, though they didn't need to stop until 2010.
Today 50% of the freon that's made in the world is made in the United States of America, and the United States, under its commitment to the Kyoto Protocol, has to shut down all of that production capacity by 2010.
For the three years leading up to when the CDM-JI board issued credits to the Asian manufacturers, in fact, the newer, long-term refrigerant substitutes had taken hold in the market, and world freon sales were diving. When the CDM-JI board--and I don't consider this a conspiracy--decided to issue credits to freon swing plant owners in Asia, the swing plant owners were making CFCs and were either going to shut down, make new refrigerants, sustainable ones, or switch over to freon.
You can look up the reports. The largest swing plant owners in Asia, since they started selling CERs, have tripled their profits. They make $2 on CER sales for every $1 they make on freon sales. The U.S. EPA says that greenhouse gas emissions will be three billion higher over the next ten years because of that decision.
