Expired, Repealed, and Archived Colorado Incentives and Laws

The following is a list of expired, repealed, and archived incentives, laws, regulations, funding opportunities, or other initiatives related to alternative fuels and vehicles, advanced technologies, or air quality.

Low Emission Vehicle (LEV) Standards Requirement

Archived: 11/01/2018

The Governor has directed the Colorado Department of Public Health and Environment (CDPHE) to develop a rule to establish a Colorado LEV program. The LEV program will incorporate the California motor vehicle emissions and compliance requirements specified in Title 13 of the California Code of Regulations. The Colorado Air Quality Control Commission must vote on CDPHE's proposed rule for adoption into the Colorado Code of Regulations by December 30, 2018. For more information, including the proposed rule, see the CDPHE LEV Standards website. (Reference Executive Order B 2018-006, 2018)

Ethanol Infrastructure Grants

Archived: 06/01/2018

The Colorado Corn Blender Pump Program provides funding assistance for each qualified station dispensing mid-level ethanol blends. Projects must meet the application requirements and receive approval from Colorado Corn and the Colorado Department of Oil and Public Safety.

Diesel-Electric Hybrid Vehicle Tax Credit

Expired: 01/01/2017

Diesel-electric hybrid vehicles that are titled and registered in Colorado are eligible for a tax credit. Light-duty diesel electric hybrid passenger vehicles with a minimum fuel economy of 70 miles per gallon are eligible for a credit of 15% of the difference of the actual cost of purchasing or leasing the vehicle and purchasing or leasing the same or most similar traditional fuel vehicle.

Light-duty passenger vehicles, light-duty trucks, or medium-duty diesel-electric truck conversions that increases the original fuel economy by at least 40% are eligible for a tax credit equal to 25% of the actual cost of the conversion.

These tax credits expire January 1, 2017.

(Reference House Bill 16-1332, 2016, and Colorado Revised Statutes 39-22-516.5, 39-22-516.7, and 39-22-516.8)

Natural Gas Vehicle (NGV) Production Support and Procurement

Archived: 04/01/2016

In 2011, Colorado joined Arkansas, Kentucky, Louisiana, Maine, Mississippi, New Mexico, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Utah, Virginia, West Virginia, and Wyoming in signing a memorandum of understanding (MOU) to stimulate the production and demand for original equipment manufacturer (OEM) NGVs. The MOU aims to encourage OEMs to offer functional and affordable light- and medium-duty NGVs, aggregate state vehicle procurement through a joint request for proposals (RFP), boost private investment in natural gas fueling infrastructure, and encourage greater coordination between state and local agencies. In 2012, National Association of State Procurement Officials coordinated the solicitation of a joint RFP, which the Oklahoma Department of Central Services (DCS) issued on behalf of the MOU signatories and additional states. As a result, state fleets have access to more affordable NGVs through dealerships now included in state vehicle purchasing bids. For more information, including awarded vehicles by state and vehicle purchase information for state fleets, see the DCS Statewide Contract for NGVs solicitation page.

Biofuels Research Grants

Archived: 06/01/2015

The Colorado Office of Economic Development and International Trade administers the Bioscience Discovery Evaluation Grant Program (BDEGP), which provides grants to help research institutions commercialize biofuels and other qualified bioscience technologies. BDEGP includes three distinct grant programs: Proof of Concept, Early Stage Company, and Commercialization Infrastructure. For the purpose of this program, biofuel is defined as a biologically based fuel product developed from plant matter or other biological material, including renewable agricultural sources. Grant limits, matching funds, and other eligibility requirements apply. As of January 1, 2015, the BDEGP is part of the Advanced Industry Accelerator Program. On an interim basis, the BDEGP will operate in its former format along with the Advanced Industry Accelerator Program. For more information, see the BDEGP website. (Reference Colorado Revised Statutes 24-48.5-108)

Electric Vehicle Charging Incentive - Xcel Energy

Archived: 10/01/2014

Qualified Xcel Energy customers can participate in a pilot program and earn a $100 credit for allowing Xcel Energy to interrupt their vehicle charging for a limited number of hours throughout the year. Xcel Energy will communicate wirelessly through a control module that interrupts power to the customer's Level 2 electric vehicle supply equipment. The pilot will run through September 2014. For more information, including the pilot program application, see Xcel Energy's Electric Vehicle Charging Station Pilot Program website

Alternative Fuel Infrastructure Tax Credit

Expired: 01/01/2011

For tax years beginning before January 1, 2011, the Colorado Department of Revenue offers an income tax credit of 20% of the cost of construction, reconstruction, or acquisition of an alternative fueling facility that is directly attributable to the storage, compression, charging, or dispensing of alternative fuels to motor vehicles. For an alternative fueling facility that will be generally accessible for public use in addition to the person claiming the credit, the credit is multiplied by 1.25. If at least 70% of the alternative fuel dispensed annually is derived from a renewable energy source for a period of 10 years, the credit is multiplied by 1.25. Certification for the percentage of renewable energy must be presented to the Department of Revenue upon request. The credit has a maximum value of $400,000 in any consecutive five-year period for each fueling facility. Excess credit may be carried forward for up to five years. For additional information, see the Department of Revenue's Income 9 FYI publication. (Reference Colorado Revised Statutes 39-22-516)

Beginning July 1, 2000, the Alternative Fuel Vehicle Credit is available from the Colorado Department of Revenue for a motor vehicle titled and registered in Colorado that uses or is converted to use an alternative fuel or is a hybrid electric vehicle. Alternative fuels include electricity, compressed natural gas, propane, ethanol, or any mixture of ethanol containing 85% or more ethanol by volume with gasoline or other fuels. The credit is a percentage of the incremental cost of the vehicle or the vehicle conversion as follows:

Category Credit Amount
Low-emitting vehicle (LEV) 50%

Greenhouse Gas (GHG) Emissions Reductions

Archived: 08/01/2010

The State of Colorado has set goals to reduce GHG emissions by 20% below 2005 values by 2020 and by 80% below 2005 values by 2050. The Colorado Department of Public Health and Environment (CDPHE) is directed to develop regulations to submit to its Air Quality Control Commission that mandate reporting of GHG emissions from all major sources. CDPHE must plan for performing updates to the state's GHG inventory and identify and evaluate the benefits and impediments to measures designed to reduce tailpipe emissions from light-duty vehicles, including the utility and availability of alternative fuel vehicles. Additionally, CDPHE must develop a proposal for reducing net GHG emissions from the state's transportation sector. (Reference Executive Order D004 08 (PDF 24 KB)) Download Adobe Reader
