EU chief Ursula von der Leyen said the 27-nation bloc will stick to the landmark Paris climate accord, despite President Trump's decision to withdraw from the agreement.

The president on Monday announced his intention to withdraw the country, for the second time, from the global emissions reduction pact.

When Trump announced the U.S. withdrawal from the climate agreement in 2017, the move reverberated around the globe. Nearly 200 nations had committed to reducing greenhouse gas emissions under the pact when it was created in 2015, and they had set ambitious targets to keep global temperature rise well below 2°C, and ideally below 1.5°C.
