The only carbon cap trading in the U.S. is now done in the northeastern states, called the Regional Greenhouse Gas Initiative (RGGI). Using cap-and-trade market RGGI's collected $360 million through the auctioning of pollution permits in 10 states. This program would stop in 2012 if an overall federal program is instituted. That could happen if pending legislation in Congress becomes law. The winner is: World Energy Solutions of Worcester, Mass. They built the software that currently runs the RGGI and nobody involved has complained. That puts World Energy Solutions in good position to be a vendor if there is a national cap and trade program.
