A new report says U.S. airlines are increasing their emissions of climate-changing gases much faster than they are boosting fuel efficiency.
The International Council on Clean Transportation said Thursday that carbon dioxide emissions and fuel burning rose 7% from 2016 to 2018, overshadowing a 3% gain in fuel efficiency.
The report’s authors say airlines could reduce emissions and fuel consumption more than 25% by buying newer planes and filling them with more passengers.
Airlines have been buying new planes, but they usually keep planes for many years to hold down costs. New airliners can carry sticker prices of more than $100 million.
The report ranks Frontier the most efficient among the 11 largest U.S. airlines because of new Airbus jets. JetBlue ranks last.
