Emission Reduction Credits


Emission Reduction Credits (ERCs) are created when certain operating facilities shut down or voluntarily curtail their emissions. In general and as part of the permitting process, certain new or expanding facilities must obtain ERCs to offset the new or increased emissions prior to constructing or modifying the air pollution sources at the facility. Thus, ERCs created by the shut down or voluntary curtailment of one facility can be sold to another new or expanding facility.
