State and Trends of the Carbon Market 2012
The total value of the carbon market grew by 11 percent in 2011, to $176 billion, and transaction volumes reached a new high of 10.3 billion tons of carbon dioxide equivalent (CO2e). This growth took place in the face of economic turbulence, growing long-term oversupply in the EU Emissions Trading Scheme (EU ETS) and plummeting carbon prices. By far, the largest segment of the carbon market was that of EU Allowances (EUAs), valued at $148 billion.
