Overview

In 2023, the CDPHE Air Pollution Control Division began operating the credit trading system for gas distribution utilities under Air Quality Control Commission Regulation 22: Colorado Greenhouse Gas Reporting and Emission Reduction Requirements. In November 2024, the division released another branch of the system for eligible industrial and manufacturing sector companies under Air Quality Control Commission Regulation 27: Greenhouse Gas Emissions and Energy Management for the Manufacturing Sector, also known as the GEMM 2 rule.

On Dec. 20, 2024, the Colorado Air Quality Control Commission adopted Regulation 7 to reduce greenhouse gas emissions from the state’s oil and gas industry. In 2028 the credit trading market will expand to include companies with midstream oil and gas fuel combustion equipment.
