The GAO is soon to publish a report faulting the credibility of the carbon offset market. It suggests that Congress think carefully before letting companies use offsets to comply with climate change legislation. Everyone has known that offsets can be sketchy for a long time, but my article in the July/August issue of Mother Jones was the first to explore how leading offset companies have partnered with oil companies and anti-regulatory lobbying firms in an effort to carve out a huge new market for themselves through climate legislation. These are the same guys to whom well-intentioned enviros have paid millions to offset car trips and airline flights. The financial meltdown has been bad enough. Let's hope it won't take a polar meltdown for Congress to realize that a laissez-faire carbon market won't save us.
