The World Bank estimates that in 2005 the market for voluntary carbon offsets made up less than 10 million tonnes (Mt) of CO2e, or less than 1 percent of global carbon market transactions and less than 1 percent of the total market value of US$11 million.
The International Emissions Trading Association and World Bank estimate that the market for carbon credits has increased to US$ 2.3 billion in the first nine months of 2006 and that the overall carbon market is now worth more than US$21.5 billion…

What are the problems? Credibility (including standards and verification), fragmentation, and overlap with the mandatory carbon emissions market.
What will happen to this market if they find out that global warming wasn’t really caused by CO2, it was methane all along?
