"A new government report says gas mileage for new vehicles dropped and pollution increased in model year 2019 for the first time in five years.

The mileage increase comes as Americans continue to buy SUVs and trucks, and shift away from more efficient vehicles.

The Environmental Protection Agency says the changes show that few automakers could meet what it called unrealistic emissions and mileage standards set by the Obama administration through the 2020 model year.

But environmental groups say that automakers used loopholes and stopped marketing fuel-efficient cars and electric vehicles knowing that the Trump administration was about to roll back mileage and pollution standards."
