Air Quality

Our mission is to improve air quality by ensuring that all CDOT projects and operations comply with federal, state, and local air quality laws and regulations, and by promoting strategies that reduce emissions of motor vehicle pollutants. In order to ensure legal compliance, CDOT evaluates the air quality impacts of its transportation projects to determine if the project will cause or contribute to a violation of National Ambient Air Quality Standards.


Guidance Manuals

The CDOT air quality procedure document is currently under review. Please see guidance available in Chapter 9 and Appendix F of the CDOT NEPA Manual.

Interested in Electric Vehicles?

CDOT is a partner in Project FEVER—Fostering Electric Vehicle Expansion in the Rockies. The objective of this project is to create a community-based electric vehicle infrastructure readiness plan and implement activities in anticipation of larger electric vehicle deployment efforts in the future.

The Electric Ride is the public education and outreach portion of this program. This interactive website is a portal of information that will help drivers get ready, get set, and go with electric vehicles as we work toward an electrified transportation future.

Learn more about how you, your business, and your community can help to reduce exhaust emissions from idling cars and trucks by visiting the Engines Off! Colorado website. There, you'll find strategies, tools, and templates to help create idling policies, active idling-reduction programs at schools and businesses, and ways to help fleets save fuel while reducing the non-operational idling.
