Market Activity

Emissions trading programs allow participants to independently determine their best compliance strategy. Participants that reduce their emissions below the number of allowances they hold may trade allowances, sell them, or bank them for use in future years. While the Acid Rain Program (ARP) and the Cross-State Air Pollution Rule (CSAPR)¹are emissions trading programs, Mercury and Air Toxics Standard (MATS) is not a market-based program; therefore, this section does not discuss MATS.

1. CSAPR refers to the CSAPR, the CSAPR Update, and the Revised CSAPR Update programs.
