The United States formally notified the United Nations that it was withdrawing from the Paris Agreement on climate change citing "unfair economic burden" on Americans.
United States President Donald Trump had announced plans to exit the Pairs climate agreement in June 2017.
In 2001, the then US President George W Bush announced that the US was withdrawing from the Kyoto Protocol, the first international climate agreement.
The Paris Agreement is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC), dealing with greenhouse-gas-emissions mitigation, adaptation, and finance.
It adapted in 2015 at CoP21 or 2015 United Nations Climate Change Conference held at Paris.
