Under those new standards, car companies will have to start designing vehicles that get an average of 54.5 miles-per-gallon, and they'll have to meet those new standards by 2025. So what does that mean at the pump for drivers locally?
Luke Metzger with the advocacy group Environment Texas says Texans should save a total of over $6 billion starting in 2030.
"Which is the year that we'll see the full impact of these new standards. And the White House estimates that means the purchaser of a new vehicle will save about $8000 over the lifetime of that vehicle."
And as for the air quality in Texas, Metzger says the new rules mean a dramatic cut in emissions, and that means less smog in big cities like Houston.
"In terms of carbon pollution, we estimate that it's gonig to reduce the pollution from vehicles by 28.2 million metric tons."
The Houston-Galveston Area Council cites figures showing the transportation sector is responsible for about 35 percent of emissions for the region.
