Discrete Emissions Reduction Credit Program
The Discrete Emission Reduction Credit (DERC) Program provides a market-based framework for trading emission reductions of volatile organic compounds (VOC), nitrogen oxides (NOX), carbon monoxide (CO), sulfur dioxide (SO2), and particulate matter with an aerodynamic diameter of less than or equal to nominal ten microns (PM10) from stationary, area, and mobile sources.
This program was designed under 30 Texas Administrative Code (TAC) §§101.370–101.376, 101.378, and 101.379 to allow additional flexibility for complying with the Texas Clean Air Act while creating a net reduction in total air emissions with each transaction.
