"MONTREAL/CANCUN -- U.S. airlines on Tuesday affirmed their support for a plan to curb emissions from flights, under review by the administration of President Donald Trump who recently decided to take the country out of Paris climate change accord.

Several U.S. airlines and industry groups said they back the global aviation agreement approved by 70 countries, including the United States, to curb greenhouse gases from international flights.

Trump said on Thursday the United States would withdraw from the landmark 2015 Paris pact to fight climate change, raising questions about whether he would also seek to back out of the 2021 voluntary phase of the airlines agreement.

Air Transport Action Group told reporters at an industry gathering in Cancun, Mexico, on Tuesday that the deal was less costly for carriers than navigating around multiple regional or national rules."
