Trump's executive order called for an immediate withdrawal from the Paris Agreement. The Agreement requires one year notice, but there's room for interpretation.

President Donald Trump pulled the US out of the Paris Agreement. The stakes couldn’t be higher for the planet and our ability to adapt.

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.
