The Paris Agreement is an international treaty signed by 196 nations in 2015. It somewhat reflects a previous global climate agreement from the Clinton Administration known as the Kyoto Protocol, which sought to reduce greenhouse gas emissions. It was a commitment by these countries to limit global warming through specific domestic actions. The Paris Agreement works on a five-year cycle of increasingly ambitious climate actions from each of the 196 signatories. At the end of each five-year cycle, each country submits an updated national climate action plan known as Nationally Determined Contribution. In 2017, President Trump withdrew the United States from the Accords, citing potential costs and job losses. President Biden officially rejoined the Paris Agreement in 2021.
