What is a Nonattainment Area in Air Quality Standards?

In United States environmental law, a non-attainment area is an area considered to have air quality worse than the National Ambient Air Quality Standards as defined in the Clean Air Act Amendments of 1970 (P.L. 91-604, Sec. 109).

Non attainment areas must have and implement a plan to meet the standard, or risk losing some forms of federal financial assistance.

 An area may be a nonattainment area for one pollutant and an attainment area for others.

The Rest @ Wikipedia

While this may have nothing to do with Green House Gases yet, I suspect that in Nonattainment areas, thresholds for reporting ghg emissions may be modified in the future
