Mitigation: Transportation


Climate Goals - Mitigation: Transportation


Transportation is the #1 source of Colorado’s Greenhouse Gas (GHG) emissions. The State is working to reduce transportation emissions by supporting electric vehicle adoption (including trucks and buses) and creating more clean transportation options, such as transit, walking, and biking. Along with the climate benefits, increasing electric transportation and clean transportation options also saves Colorado residents and businesses money, while reducing air and noise pollution and making our communities safer and healthier. 

Colorado is first in the region and third in the nation on Transportation Electrification, according to the American Council for an Energy Efficient Economy, and started a leading statewide e-bike rebate program.


State of Colorado Transportation – Goals & Actions

Colorado is working to reduce transportation-related GHG emissions by 41%, or 12.7 million metric tons, by 2030 from 2005 levels. To meet this goal, the state is:

  • Ensuring auto and truck manufacturers make a variety of zero-emission vehicle options available at Colorado dealerships.
  • Investing in electric vehicle charging and offering incentives for electric vehicle purchases.
  • Prioritizing GHG emissions reduction opportunities when developing and approving plans for new transportation projects.
  • Expanding public transportation and shared transportation options (e.g., electric car-shares).
  • Enabling adoption of zero-emission trucks, buses, and electric bikes.
  • Mitigating emissions from facilities that generate significant amounts of traffic.  

Key Priorities


The State has set electrification goals for light-, medium-, and heavy-duty vehicles including:

  • 940,000 light-duty EVs on Colorado roads by 2030, 2.1 million by 2035, and 100% of light-duty vehicles on the road by 2050.
  • 35,000 zero-emission medium- and heavy-duty vehicles on the road by 2030; 30% of new medium- and heavy-duty vehicle sales are zero-emission vehicles by 2030, and 100% by 2050. This includes 100% of transit vehicles by 2050 and 100% of school buses by 2035.
  • 1,700 Direct Current Fast Chargers (DCFC) and 5,800 Level 2 chargers in Colorado by 2025.


  • Ensuring auto dealerships in Colorado sell all low-emission vehicles, and a minimum percentage of zero-emission vehicles, by 2025. Rules for after 2025 are currently under development. Learn more: Colorado Clean Cars | Department of Public Health & Environment.
  • Ensuring manufacturers of medium- and heavy-duty vehicles sell an increasing percentage of zero-emission vehicles starting in model year 2027. Learn more: Advanced Clean Trucks and Low NOx rule.
  • Offering grant funding to install chargers for electric vehicles (charging infrastructure) across the state. This includes community charging, fast charging along major roadways, and fleet vehicle charging infrastructure.
  • Creating incentives to purchase or lease zero-emission vehicles, including tax credits and income-qualified rebates for recycling high-emitting vehicles. Grants are also available to school districts (including those operated by tribal governments, charter schools, and non-profit organizations applying on behalf of a school district or charter school) and transit agencies for purchasing zero-emission school buses and transit buses. Public, private, local government, and non-governmental organizations may also be eligible for grants for electric fleet vehicles.
  • Increasing Coloradans’ knowledge and awareness about electric vehicles and their benefits, EV charging, and incentives through the statewide EV CO campaign, which includes a website and social media engagement.
  • Promoting equity in electric vehicle access and adoption through focused outreach and stakeholder engagement, income-qualified electric vehicle purchase incentives, and additional funding for electric vehicle charging projects in disproportionately impacted communities. This is outlined in detail in the state’s EV Equity Study.
  • Growing the state’s electric vehicle workforce by creating opportunities to train new and veteran mechanics, vehicle technicians, electricians, and other workers in Colorado to service electric vehicles. This includes training courses through the Colorado Community College System, as well as a needs analysis to inform future workforce development.
  • Providing grants to fund innovative mobility and electrification solutions.
  • Leading by example while transitioning state-owned vehicles to electric vehicles.

In addition to electric vehicles, the State is working to increase the use of e-bikes, e-scooters, and shared electric transportation options to reduce emissions from cars. This includes increasing access to e-bikes through tax credits for all Coloradans, as well as financial incentives and community projects for low- and moderate-income Coloradans, with the target of at least 10,000 new e-bike owners by 2025.


  • E-bike purchase incentives: As of April 1, 2024, all Colorado residents purchasing an e-bike can receive a $450 tax credit deducted from the price of the e-bike at the time of purchase. In August 2023, low- and moderate-income Coloradans became eligible to apply for an e-bike rebate for an additional discount at the time of e-bike purchase.
  • Community-based programs: The state offers funding for local governments, non-profit organizations, and others to develop programs that increase access to e-bikes and other shared transportation options, especially for low- and moderate-income Coloradans. Key programs include the e-bike grant program and Community Accelerated Mobility Project (CAMP).


  • Widespread public transportation use prevents traffic, reduces emissions from cars, and improves air quality. The state aims to increase public transportation use in Colorado by ensuring transit systems are affordable, efficient, and easy to use, while providing local, regional, and interregional connectivity.
  • The state also has a goal to reduce emissions from transit vehicles by transitioning 1,000 public transit vehicles to zero-emission vehicles by 2030, and 100% by 2050.


  • Offering funding to transit agencies in Colorado to provide free public transportation during summer months when air quality is at its worst.
  • Providing affordable and reliable bus service connecting cities and towns across the state.
  • Supporting public transit electrification planning efforts, facility upgrades, fleet motor vehicle replacement, and construction of electric motor vehicle charging and fueling infrastructure through the Clean Transit Enterprise.
  • Colorado Department of Transportation’s Bustang program provides service along I-25 and the I-70 mountain corridor, as well as service to rural areas, mountain resorts, and other attractions.
  • Supporting a mix of projects that improve access to travel options beyond single-occupancy vehicles. Along with Bustang, this includes new mobility hubs that help commuters catch the bus or connect with a carpool, as well as strategic integration of transit elements into roadway projects.
  • Building the Bus Rapid Transit projects as the State set aside $170 million to develop projects on key Denver streets: Federal Boulevard, Colorado Boulevard, and East Colfax Avenue. Rapid transit projects and improvements are also in the works between Boulder and Longmont and along CO Highway 7.
  • The Front Range Passenger Rail District is working to fund a Front Range passenger rail system. This 180-mile corridor stretches between Fort Collins, Denver, and Pueblo.
