The US and the Paris Agreement: A Tumultuous History
- The Paris Agreement (2015): The accord was adopted by 196 parties in 2015, aiming to limit global warming to well below 2°C above pre-industrial levels. The US, under President Obama, was a key architect and signatory.
- First Withdrawal (2017–2020): In 2017, President Donald Trump announced the US intention to exit, citing economic disadvantages. The formal withdrawal took effect on November 4, 2020.
- Rejoining and Second Withdrawal: President Joe Biden rejoined the agreement on his first day in office in 2021. However, when Trump returned to power in 2025, he immediately signed an executive order to withdraw the United States again, making it the only major emitter to leave the pact twice.
- Global Implications: The US is the world's second-largest greenhouse gas emitter. Its departure significantly undermines global climate efforts and places greater responsibility on the remaining signatories, including China and the European Union.
Therefore, the country that left the Paris Agreement according to the 2025 report was the USA.
