Adopted Clean Air Interstate Rules (CAIR)

CAIR is a Federal regional emissions trading program developed for states within the eastern region of the United States. It is designed to mitigate interstate transport of nitrogen oxides (NOx) and sulfur dioxide (SO2) to help reduce ozone and fine particulate matter (PM2.5) formation in CAIR states located in the eastern United States. The Department has adopted three Clean Air Interstate Rules (CAIR) that will establish New York State's portion of the cap-and-trade programs. These rules consist of Part 243, CAIR NOx Ozone Season Trading Program; Part 244, CAIR NOx Annual Trading Program; and Part 245, CAIR SO2 Trading Program.
