SACRAMENTO, Calif. (AP) — The U.S. government is moving forward with requirements that states track vehicle emissions on federal highways after California and seven other states sued over what they called an unlawful delay.

But federal transportation authorities might end the new rules next year anyway.

The rules say states must track greenhouse gas emissions from vehicles, a major source of carbon emissions, and set targets for how much can be spewed into the air on federal highways.

The Trump administration has repeatedly delayed the rules beyond their February 2017 effective date, prompting the lawsuit. They're now moving ahead as of Thursday. But federal officials are also beginning a review on whether they should exist at all.

Federal Highway Administration spokesman Doug Hecox says the rules may not be effective or needed.
