Delta is the first major U.S. airline to say it will not rollback its climate targets after Trump withdrew the U.S. from the Paris Agreement.

President Donald Trump ordered the U.S. to withdraw from the Paris climate agreement on Monday, once again placing the world's top historic emitter of greenhouse gases outside the global pact aimed at pushing nations to tackle climate change.

The president signed an executive order that raises questions about the timing of his planned exit from the global climate deal.
