HB 23-1272, Tax Policy That Advances Decarbonization

Concerning tax policy that advances decarbonization, and, in connection therewith, extending tax credits for the purchase or lease of electric vehicles; creating tax credits for industrial facilities to implement greenhouse gas emissions reduction improvements, for expenditures made in connection with geothermal energy projects, for production of geothermal electricity generation, for the deployment of heat pump technology, for retail sales of electric bicycles, and for construction of sustainable aviation fuel production facilities; creating a temporary specific ownership tax rate reduction on a portion of the sale of electric medium- and heavy-duty trucks; temporarily decreasing the severance tax credit for oil and gas production, requiring the revenue that is attributable to the decrease be deposited in the decarbonization tax credits administration cash fund, and creating the cash fund; and making an appropriation.

The State of Colorado passed HB23-1272 Tax Policy That Advances Decarbonization. This bill creates a new, refundable income tax credit for tax years 2024 through 2032 for costs incurred to construct or reconstruct a sustainable aviation fuel production facility. This tax credit is called the Aviation Emission Reduction Offering (AERO). To remain eligible for the full credit, sustainable aviation fuel (SAF) must make up at least 60 percent of total fuel production at the facility or in distribution. Such facilities or distribution projects will provide airline carriers, who have demonstrated a strong demand for such fuels, with a steady supply of SAF for utilization at Denver International and other airports throughout the region.


Aviation Emission Reduction Offering

The Colorado Energy Office (CEO) will provide refundable, merit-based tax credits to support eligible geothermal projects in Colorado,  including developing and producing geothermal electricity, installing a thermal energy network, or conducting a thermal energy network study. CEO will award the Geothermal Energy Tax Credit Offering (GETCO) through a competitive process, providing a total of $35 million in state investment tax credits (ITC). A production tax credit (PTC) is also available for electricity production.

Geothermal Energy Tax Credit Offering

The Colorado Industrial Tax Credit Offering (CITCO) is a competitive, refundable tax refund administered through Colorado Energy OFfice. A total of $168 million in tax credits will be available over the program’s nine-year duration, through December 31, 2032.

Industrial facilities may apply for this refundable tax credit to conduct industrial studies, such as energy and emissions audits, feasibility studies, or front-end engineering and design studies; or implement improvements that reduce emissions, such as electrification, carbon management, hydrogen utilization, and waste heat recovery. CEO will award up to 30% of approved costs for selected projects, not to exceed $1 million for studies or $5 million for improvements.

Regulation 31: Control of Methane Emissions from Municipal Solid Waste Landfills (Proposed)

The Air Pollution Control Division proposed a rule to reduce methane pollution from municipal solid waste landfills, which would address one percent of total state GHG emissions. The commission has scheduled the final rulemaking hearing for August 2025.

Regulation 7: Control of Emissions from Oil and Gas Emissions Operations (2025 Amendment)

Colorado adopted new rule amendments that set a phase-out schedule for natural gas-driven pneumatic devices at oil and gas facilities statewide. Oil and gas operators in Colorado must achieve a phase out of 25 percent by May 2026, 50 percent by May 2027, 75 percent by May 2028, and 100 percent by March 2029. Further, operators that do not meet federal health standards for ground-level ozone pollution must phase out the use of these devices more quickly.

State health department seeks input on reducing greenhouse gas emissions from Colorado landfills

The CDPHE Air Pollution Control Division is starting public meetings focused on reducing greenhouse gas emissions from municipal solid waste landfills. These landfills are significant sources of methane, a powerful greenhouse gas that contributes to climate change. Addressing emissions from municipal solid waste landfills will help Colorado achieve its ambitious climate goals.
