Amendments adopting Low-Emission Vehicle and Zero-Emission Vehicle air pollution standards (Revisor’s ID R-4626)

Supplemental resources

Detailed overview of the concepts MPCA is considering for the Clean Cars Minnesota rulemaking. This document will help readers understand the potential rules being considered and their rationale.

Colorado is the most recent state to have adopted these standards. MPCA is considering using Colorado’s rule language and regulatory analysis as a model from which to develop our own. Several of the questions in our supplement document refer to Colorado’s materials.

During the RFC period, we held a series of public meetings around the state to share information and gather input from Minnesotans.
