The Paris Agreement is an international treaty that was adopted in December 2015 at the United Nations Climate Change Conference (COP21) in Paris, France. The agreement aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels, with a target of 1.5 degrees Celsius. It also includes commitments from countries to reduce their greenhouse gas emissions and to enhance their climate change adaptation efforts.
As of 2021, 197 countries have signed the Paris Agreement, including the United States, China, and the European Union. The agreement is seen as a landmark achievement in the global fight against climate change, as it represents a collective effort to address the urgent need to reduce greenhouse gas emissions and mitigate the impacts of climate change.
