BRUSSELS — Donald Trump blew up global efforts to cut emissions from shipping, and now the EU is terrified the U.S. president will do the same to any plans to tax carbon emissions from long-haul flights.

The European Commission is studying whether to expand its existing carbon pricing scheme that forces airlines to pay for emissions from short- and medium-haul flights within Europe into a more ambitious effort covering all flights departing the bloc.

If that happens, all international airlines flying out of Europe — including U.S. ones — would face higher costs, something that’s likely to stick in the craw of the Trump administration.
