Clean Air Interstate Rule (CAIR)

On March 10, 2005, EPA issued the Clean Air Interstate Rule (CAIR). CAIR covers 27 eastern states and the District of Columbia. The rule uses a cap and trade system to reduce sulfur dioxide (SO2) and nitrogen oxides (NOx) by 70 percent.

 

Affected states must achieve the required emission reductions using one of two compliance options:

    1. meet the state's emission budget by requiring power plants to participate in an interstate cap and trade program that caps emissions in two stages, or
    2. Meet an individual state emissions budget through measures of the state's choosing
