February 4 , 2026 14 hrs 0 min 20 0
  • The United States is officially out of the Paris Agreement under the administration of President Donald Trump.
  • It was making it the only country to quit the historic climate pact twice.
  • It makes the U.S. the only country to abandon the global pact, having previously rejoined in 2021 under President Biden after an initial 2017 withdrawal.
  • The United States is the world's second biggest greenhouse gas emitter after China.
  • The only other UN member states outside the Paris agreement are Iran, Libya and Yemen.
  • The Paris Agreement is a legally binding international treaty adopted in 2015 (COP21) by 195 parties to limit global warming to well below 2C —ideally 1.5C —above pre-industrial levels.
  • It requires countries to submit increasingly ambitious, voluntary climate plans known as Nationally Determined Contributions (NDCs) every five years.
  • The 1.5 °C target is generally accepted to refer to a 20-year average, rather than a single year.
