Members of a major automotive trade group are reportedly set to meet with Transportation Secretary Elaine Chao and Environmental Protection Agency Administrator Scott Pruitt this week regarding Obama-era fuel efficiency standards.

The meeting reported by Reuters on Wednesday comes as both agencies begin a review of federal fuel efficiency rules ordered by President Trump as part of a broad rollback of climate change policies enacted by former President Obama.

The Obama rules aimed to double average fuel efficiency among an automaker’s fleet to 54.5 miles per gallon by 2025. In 2011, Obama said the rules would save drivers $1.7 trillion in fuel costs but would cost the auto industry $200 billion over 13 years.

Both California and New York have threatened to set fuel efficiency standards on their own if Trump weakens the standards set under Obama, which could hamper Trump’s efforts to negotiate a federal standards deal that would apply to all 50 states.

Automakers want a nationwide standard to reduce costs for complying with the measure.

This week’s meeting between Trump officials and automakers is the first since Trump announced that his administration would re-open a review of the standards in March.
