Mass Emissions Cap and Trade Program
The MECT Program is a market-based cap-and-trade program that implements an annual nitrogen oxides emission cap for applicable facilities in the Houston-Galveston-Brazoria ozone nonattainment area.
Program participants are required to use allowances or discrete emission credits to cover NOX emissions on an annual basis. The allowances available for use each year are capped at a level necessary to attain the National Ambient Air Quality Standards for ozone. Participation from applicable facilities is mandatory.
For more information, including applicability requirements, refer to 30 TAC Chapter 101, Subchapter H, Division 3
Chapter 117, Subchapter B, Division 3
Chapter 117, Subchapter C, Division 3
and Chapter 117, Subchapter D, Division 1. ![]()
