This decision became official on January 27, coinciding with the one-year anniversary of the notification sent by the Donald Trump administration to the UN.
The order to withdraw from the agreement was signed by Trump on the day of his inauguration in January 2025.
The goal of the Paris Agreement is to limit global warming and minimize the risks from the most severe consequences of climate change.
Thus, the United States is no longer obligated to meet greenhouse gas emission reduction requirements and is ceasing its participation in international climate summits. This may also negatively impact the funding of programs designed to assist the least developed countries in adapting to climate change and protecting against its effects.
The U.S. ranks second in the world for greenhouse gas emissions, surpassed only by China. According to UN forecasts, if current climate policies remain unchanged, by the end of the 21st century, the average temperature on the planet could increase by 2.8 degrees compared to pre-industrial levels. The U.S. withdrawal from the agreement could raise this figure by an additional 0.1 degrees.
This is not the first instance of the U.S. withdrawing from the Paris Agreement under Donald Trump; during his first presidential term, the United States already left it, but under Joe Biden, it returned to the agreement.
Additionally, Trump previously signed a bill that ends U.S. funding and participation in 66 international organizations.
The United States has also officially withdrawn from the World Health Organization (WHO).
