U.S.-based airlines are getting more fuel-efficient, but Americans are traveling more and erasing potential gains, according to a study out Thursday.

By the numbers: Fuel efficiency of airplanes has increased by 3% between 2016 and 2018, but the miles passengers have traveled increased 10%. Thus, fuel use and carbon dioxide emissions rose by 7%, according to the report by the International Council on Clean Transportation (ICCT), a nonprofit environmental group.

With 2 crashes in less than 6 months, President Trump and the Federal Aviation Administration's decision to ground Boeing 737 MAX jets had swift and significant impacts on airlines and travelers.

What they're saying: Trump told reporters that the decision was "precautionary," and "fact-based." Three major airlines have 737 in their fleets.
