In November 2020, 194 states and the European Union signed the agreement. 188 states and the EU, which account for about 79% of global greenhouse gas emissions, have ratified or acceded to the agreement, including China and India, the first and third largest CO2 emitting countries among UNFCCC members.

He adds: “The ability to import international goals into achievable national laws and policies and to implement those goals will have a big influence on the success of the Paris Agreement.” On June 1, 2017, U.S. President Donald Trump announced that the United States would withdraw from the agreement.  In accordance with Article 28, on the 4th If it had decided to withdraw from the UNFCCC by leaving the UNFCCC, it could be immediately denounced (the UNFCCC entered into force for the United States in 1994) and enter into force a year later.

The invitation to resign could only be presented after the agreement entered into force for the United States for three years in 2019.   The report “Global trends in climate change legislation and litigation: snapshot: 2018 snapshot” also highlights that more than 1500 national climate change laws and policies are now in place worldwide, 106 of which have been created since the arrival of the Paris Agreement at the end of 2015. Iran (1.66%), Turkey (1.04%) and Iraq (0.48%) are currently the top emitters among the 10 nations that have not yet ratified. The others account for a much smaller share of global emissions: Eritrea (0.01%), Libya (0.14%), South Sudan (0.24% with Sudan) and Yemen (0.07%). The Paris Agreement is an agreement within the UNFCCC (UNFCCC), which deals with the reduction, adaptation and financing of greenhouse gas emissions from 2020 on.
The agreement aims to address the global threat of climate change by maintaining a global temperature increase well below 2 degrees Celsius this century and continuing efforts to further limit the temperature increase to 1.5 degrees Celsius.  Turkey is now the only G20 member not to have formally approved the agreement after it was ratified by Russia in October 2019.
