In June 2018, Colorado Governor John Hickenlooper announced that his state would join 13 states and the District of Columbia in adopting California’s clean car emissions standards.

The governor’s first Executive Order directed the Colorado Air Quality Control Commission (AQCC) to consider a proposed rule adopting a California Low Emission Vehicle (LEV) Standard. The AQCC passed Regulation 20 – The Colorado Low Emission Automobile Regulation (CLEAR) – on November 16, 2018. 

The public comment period included extensive public comment in support of both Low and Zero Emission Vehicle Rules. In January 2019, Governor Hickenlooper responded to these comments with another Executive Order, directing agencies to develop a rule to establish a Zero Emission Vehicle (ZEV) program to boost sales of electric vehicles.

In August 2019, the Colorado Air Quality Control Commission (AQCC) voted to adopt a ZEV rule.

Throughout both rulemaking processes, the proposals faced pushback from oil industry defenders, auto dealers, and free market organizations tied to the Koch network.
