As of 2021, there are only two countries in the world that have not signed the Paris Climate Agreement. These countries are Iran and Eritrea.
The Paris Climate Agreement is a global agreement signed by countries that aims to keep global warming below two degrees Celsius above pre-industrial levels while pursuing efforts to limit it to 1.5 degrees. The agreement also aims to strengthen the ability of countries to deal with the impacts of climate change and to mobilize resources to support climate action.
Iran and Eritrea have not signed the agreement for different reasons. Iran, a major oil-producing country, has cited concerns over how the agreement would impact its economy, which heavily relies on the export of oil. Eritrea, on the other hand, has not given any reasons for its decision not to sign but is a small and impoverished country with limited resources to address climate change.
The decision by these two countries not to sign the Paris Climate Agreement has been criticized by many environmental activists who argue that tackling climate change requires collective action from all countries. The non-participation of these countries makes it more challenging to meet the goals set out by the Paris Agreement.
It is worth noting that while the two countries have not signed the agreement, they are still eligible to do so in the future. The Paris Climate Agreement is an ongoing process, and countries can join as signatories at any time.
In conclusion, while the majority of the world`s countries have signed the Paris Climate Agreement, Iran and Eritrea have not. However, it is hoped that these countries will reconsider their position in the future and join other nations in the fight against climate change.
