On January 20, 2025, the day of his inauguration, U.S. President Donald Trump signed an executive order announcing the United States’ withdrawal from the Paris Agreement. On January 28, 2025, the United Nations confirmed receipt of the U.S. notification to withdraw from the climate-focused accord, with the withdrawal set to take effect on January 27, 2026.

Regarding the U.S. exit from the Paris Agreement, Farhan Haq, Deputy Spokesperson for the UN Secretary-General, responded to a question from CCTV by stating that all nations must fulfill their obligations to address climate change and that the UN opposes any attempts to evade such commitments.

Farhan Haq, Deputy Spokesperson for the UN Secretary-General:

“We believe it is imperative for all countries to uphold their responsibilities in combating climate change. This is a critical issue demanding collective action from all nations. Therefore, we oppose any efforts to circumvent these commitments.”

On January 20, 2025, U.S. President Donald Trump signed an executive order on his inauguration day, announcing the United States’ withdrawal from the Paris Agreement. On January 28, 2025, the United Nations confirmed it had received formal notification of the U.S. withdrawal from the climate accord, which will take effect on January 27, 2026.

The Paris Agreement, adopted during the 2015 UN Climate Change Conference (COP21), marked a pivotal global achievement in addressing climate change. In June 2017, then-President Trump first declared the U.S. intention to exit the agreement, leading to its formal withdrawal on November 4, 2020. This move drew widespread criticism domestically and internationally.

On January 20, 2021, President Joe Biden reversed the decision by signing an executive order to rejoin the accord on his first day in office. The U.S. officially rejoined the agreement on February 19, 2021. However, on January 20, 2025, President Trump once again announced the U.S. withdrawal from the Paris Agreement upon taking office.
