Sad news: SO2 is dead

Tim Haab reports from the Heartland that the teetering SO2 cap and trade market is "Elvis dead."
The story goes something like this: The SO2 market was designed as if SO2 was a uniformly mixed pollutant. This made trading easier. One ton of SO2 in Ohio could be traded for one ton in Illinois. But, the impacts of each of those tons is different. Those states who absorbed a disproportionate impact from SO2 trading sued the EPA. Congress issued the Clear Air Interstate Rules limiting interstate trades of SO2. SO2 prices crashed. EPA lost the lawsuit: Must scrap the SO2 market and start over. SO2 market dies quietly.
Leaving us without a textbook example of market-based environmental policy... and that is the least of it.
