U.S. airlines are increasing their emissions of
climate-changing gases much faster than they
are boosting fuel efficiency, according to an
environmental group’s report.
The International Council on Clean Transportation
said 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.
The report ranked Frontier the most efficient
among the 11 largest U.S. airlines. The Denver-
based carrier has added more than 40 Airbus
jets with more efficient engines.
New York-based JetBlue ranked last.
