Acid Rain Auction Project Homepage

Once a year, EPA auctions a certain number of SO2 and NOx allowances at the end of March. Utilities, environmental groups, allowance brokers, and anyone else interested in purchasing allowances can participate. Under both the Acid Rain Program and the Ozone Transport Commission NOx Budget Program, anyone can purchase allowances, including both regulated companies and members of the general public. Some individuals and groups purchase allowances as an environmental statement, because withholding allowances from the market prevents those allowances from being used by utilities.
