DENVER — Colorado’s governor on Tuesday ordered his state to adopt vehicle pollution rules enforced in California, joining other states in resisting the Trump administration’s plans to ease emission standards.
Democratic Gov. John Hickenlooper told state regulators to begin writing rules that incorporate California’s low-emission standards with a goal of putting them in place by the end of the year.
Hickenlooper said the strict standards are important to Colorado, citing climate change and noting the state’s elevation makes pollution worse.
“Our communities, farms and wilderness areas are susceptible to air pollution and a changing climate,” his order said. “It’s critical for Coloradans’ health and Colorado’s future that we meet these challenges head-on.”
Hickenlooper’s order came about three months after the U.S. Environmental Protection Agency announced it would not implement stricter emissions rules adopted by the Obama administration. Those rules would have started with the 2022 model year.
California has a waiver under federal Clean Air Act allowing it to impose tougher standards than the U.S. rules. Currently, California’s standards are the same as the federal standards. But if the Trump administration foregoes the stricter Obama-era rules, California could still impose them or others.
