Global Automakers provided a letter to the Colorado Department of Public Health and Environment on considerations as the staff works on development of a ZEV mandate. In Colorado, the process is to develop regulations to present to the Air Quality Control Commission in a public format. The Commission then decides whether to proceed with the formal rulemaking. Global Automakers input was targetted at the regulatory constraints, the need for legislative input, the associated programmatic costs, ad the need for complementary electric vehicle market development.
