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.

This is the second time Trump has confirmed he will be withdrawing from the Paris agreement — the first was during his first term in 2017. When Biden became president in 2021, he rejoined the agreement.

Trump signed an executive order that begins the process of withdrawing from the Paris Climate Agreement, which he also did during his first term.
