Emission Reduction Credit Program

The Emission Reduction Credit (ERC) program creates a consistent method for sources to generate ERCs for future use in offsetting emissions in nonattainment areas throughout Maricopa County.

The ERC program provides both new and expanding Arizona businesses added opportunity in meeting mandatory federal Clean Air Act requirements to improve air quality while still allowing industrial development. This program allows participants to generate credits by creating permanent emission reductions from stationary and area sources in nonattainment areas. Participation is completely voluntary.
