Colorado Adopts California’s Low Emission Vehicle Standards

Published: November 19, 2018

On November 16th, the Colorado Air Quality Control Commission made a unanimous decision to join 12 other states and the District of Columbia in adopting California’s rules for low-emissions vehicles (LEV). The decision will make new cars sold in this state have to meet a higher standard than the federal government requires, and it will put Colorado in place to reduce carbon-dioxide emission significantly in the next decade. It is estimated the proposal would lead to a $750 million cumulative annual increase in the cost of new vehicles, offset by $2.9 billion in fuel-cost savings over the life of the vehicle.

Colorado’s rules would start affecting new lightweight and medium-duty vehicles in 2022. The goal is to reduce pollutants by increasing the corporate average fuel economy (CAFE) standard. The CAFE standard is the average miles per gallon for cars produced in a single calendar year, and the new rules require 36 mpg by 2025.
