Trump's announcement doesn't guarantee the rollback of the Obama standards but opens the door for the request for review from carmakers.
In a speech after the meeting, Trump promised the government's final determination would "ensure that any regulations we have protect and defend your jobs, your factories". Trump's willingness to hit the brakes underscores his administration's aim to roll back environmental rules in order to boost economic growth.
A White House official briefing reporters said the Trump administration will spend the next year working on the review to determine if the 2022-2025 model-year rules are feasible.
"America can not be a wealthy country if special interests game the system to profit from the exodus of our companies and from the exodus of our jobs", Trump said.
"I'm sure you've all heard the big news that we're going to work on the café standards so you can make cars in America again", said Trump.
The backdrop and message underscored Mr Trump's efforts to lock down support in industrial states such as MI that put him in the White House. Despite their complaints, automakers have achieved mandated improvements in fuel efficiency in the past, and some vehicles meet the 2025 target already.

The official said the administration wanted to put the review "back on track" and that no decision had been made to loosen the standards.
Thirteen other states have adopted California rules that account for about 40 percent of USA vehicle sales.
The bottom line is that the Trump administration is going to war with our natural environment and we must stand together to stop him.
That review will reconsider the Obama administration's January determination that automakers should continue to abide by that standard. Instead, they have pitched their new review as one created to fulfill the government's agreement with auto manufacturers.
Young says, "We don't know how it would work and were very concerned that it might happen".
In the United States, which accounts for about 10 percent of global gasoline usage, demand hit a record in 2016, averaging 9.3 million barrels per day, surpassing 2007 levels, according to the U.S. Energy Information Administration. The auto industry has opposed that decision and considers the goal too expensive and hard to reach given Americans' vehicle buying habits.
In a February letter to Environmental Protection Agency (EPA) Administrator Scott Pruitt, US auto manufacturers had asked the new president to suspend the Obama administration's restrictions, saying they could threaten employment.
