Reducing Greenhouse Gas Emissions from Transportation

Colorado state government is seeking public input on an upcoming rule to reduce greenhouse gas (GHG) emissions and other air pollutants from transportation in Colorado as part of an ambitious effort to address climate change and meet the state’s science-based climate targets of 26% by 2025, 50% by 2030% and 90% by 2050 from 2005 levels, outlined in the state Greenhouse Gas Pollution Reduction Roadmap

Main Rule Components

Employee Traffic Reduction Program (ETRP)

Employee Traffic Reduction Program (ETRP) (Fact Sheet) (RAQC Resources)

The Employee Traffic Reduction Program is currently being considered by the Air Pollution Control Division as a potential greenhouse gas reduction strategy for employers within Colorado's Ozone Nonattainment Area with 100 or more employees at one worksite. Since fall 2020, the Regional Air Quality Council (RAQC) has worked with stakeholders to develop and refine a draft ETRP concept for consideration by the RAQC Board. The Division is evaluating these strategies and listening to stakeholder feedback.

Greenhouse Gas Pollution Standard

(CDOT resources)

One of the key recommendations stemming from the Governor’s Greenhouse Gas (GHG) Roadmap is the adoption of a new GHG Pollution Standard for the transportation sector. In addition to having an active role in the rule development, the Colorado Department of Transportation (CDOT) is also working to ensure this effort is fully informed by transportation stakeholders from around the state.

Vehicle Emission Inspection Program 

The Division is also exploring ways to make Colorado’s vehicle inspection program more effective. Changes to the inspection program would likely be considered as part of a broader GHG Transportation Rulemaking.  

Transportation Rulemaking Process

  • Stakeholder Engagement: ongoing
  • May 20-21, 2021: Request for Rulemaking Hearing before the Air Quality Control Commission
  • August 19-20, 2021: anticipated Rulemaking Hearing before the Air Quality Control Commission 

Engagement Opportunities

Greenhouse Gas Pollution Standard: Stakeholder meetings can be found at the CDOT website: www.codot.gov/programs/environmental/greenhouse-gas/ghg-transportation-policy-rulemaking-process

The Employee Traffic Reduction Program: The state held four listening sessions in March and is hosting more in April to hear input from employers on possible strategies. Note: all listening sessions will provide the same overview information. If you would like to participate in a listening session, please register here: APRIL LISTENING SESSION REGISTRATION
