According to Bart Chilton, a commissioner at the U.S. Commodity Futures Trading Commission, carbon emissions trading could become the world’s leading derivatives product as businesses in the U.S. and Asia take steps to decrease their greenhouse gas emissions and competition heats up between exchanges. Mr. Chilton further went on to say that he “can certainly see carbon becoming the biggest of any derivatives product in the next four to five years. And that would of course mean overtaking T-bills [Treasury] and any contract that is out there right now.”
