Colorado’s GHG Emission Reduction Goals

According to House Bill 19-1261 Climate Action Plan to Reduce Pollution, Colorado shall have statewide goals to reduce 2025 greenhouse gas emissions by at least 26%, 2030 greenhouse gas emissions by at least 50%, and 2050 greenhouse gas emissions by at least 90% of the levels of statewide greenhouse gas emissions that existed in 2005.

Steps to Achieving 2030 Targets

  • Continue transition of utilities away from coal to renewable electricity
  • Increase building efficiency and electrification
  • Accelerate the shift to electric cars, trucks and buses
  • Make changes to transportation planning and investment and land use planning to encourage alternatives to driving
  • Make deep reductions in methane pollution from oil and gas development
  • Reduce methane waste from landfills, waste water and other sources

Benchmarking Requirements

The “Energy Performance for Buildings” Statute (House Bill 21-1286) passed the Colorado General Assembly on June 8, 2021 and went into effect on September 6, 2021. This law requires owners of large commercial, multifamily, and public buildings 50,000 square feet or more to annually benchmark their whole-building energy use to the Colorado Energy Office (CEO).  

On or before December 1, 2022 and on or before June 1 of each following year, the owner of a covered building is required to submit a report that includes a full 12-months of whole-building energy usage (electric, natural gas, district steam, district hot and chilled water, solar, wind, etc.) for the previous year.

If a building is benchmarked within the City of Denver, the City will pass along the submitted benchmarking report, but the building owner must go to to pay the $100 annual filing fee to be considered compliant at the state level.

Building Performance Standards

House Bill 21-1286, the ‘Energy Performance for Buildings’ statute, directed the Colorado Energy Office to convene a Task Force to develop Building Performance Standards (BPS) to meet sector-wide greenhouse gas (GHG) reduction targets of 7% by 2026 and 20% by 2030. The BPS recommendations, which must be approved by two-thirds of the Task Force members, will be reviewed and decided on by the Air Quality Control Commission (AQCC) in 2023.

Building Performance Standards (BPS) will drive sector-wide greenhouse gas (GHG) reduction targets of 7% by 2026 and 20% by 2030 for all buildings over 50,000 ft2 in the State of Colorado.

Colorado Building Codes

Colorado legislature has passed House Bill 22-1362 Building Greenhouse Gas Emissions.  Once signed, the bill will require local governments and certain state agencies to adopt and enforce codes that are consistent with two of the model codes, encouraging local governments and certain state agencies to 3 sets of model code language:

  • Electric and solar ready code language;
  • Low energy and carbon code language; and
  • Green code language.

The bill will also create:

  • Building electrification for public buildings grant program,
  • High-efficiency electric heating and appliances grant program, and,
  • The clean air building investments fund.
