The United States has officially notified the Secretary-General of its withdrawal from the Paris Climate Agreement, effective 27 January 2026, UN Spokesperson Stéphane Dujarric said on Tuesday.

The 'historic accord' reached by 193 countries in December 2015 in a bid to keep temperature rises to below 1.5°C above pre-industrial levels, was signed by the US on 22 April 2016, read the UN website.

During the first Trump administration the US withdrew from the Agreement effective 4 November 2020, before his successor took the country back into the accord on 19 February 2021.

In a repeat of his 2017 stance, US president Donald Trump pulled out the nation from the climate agreement - dubbed as Paris Accord - in one of the major executive orders he took after swearing in at the Capitol One Arena in Washington on January 20.

Trump pulled the US out of the agreement in 2017 after assuming the office.

But it was undone by Trump's immediate predecessor Joe Biden, who departed from the White House on Monday, after taking charge in 2021.

The Paris Agreement, a non-binding treaty, was formed aiming at a global cooperation to minimise the causes of global warming.

The US will join countries like Iran, Yemen and Libya to opt out of the Paris Accord which was inked in the French capital Paris a decade ago.

Among other major decisions which he took on the day of his inauguration, Trump signed an order to opt the US out of the World Health Organisation (WHO).
