The United States (US) became the first country in the world to officially withdraw from the 2015 Paris Climate Agreement.
US President Donald Trump announced the move in June 2017 but due to the terms and conditions of the agreement, the decision can only be enforced starting yesterday.
According to the terms of the agreement, no country is allowed to resign for three years after the agreement is signed.
Although the agreement was signed in December 2015 but its implementation is only effective on 4 November 2016.
However, the US is still allowed to rejoin the agreement in the future.
The agreement is designed to strengthen the global response to climate change threats.
Trump had previously claimed that the agreement placed an unfair financial and economic burden on the US.
He also claimed that the agreement gave undue advantage to other countries such as China and India which contributed more pollution to the world besides destroying employment opportunities in the US.
Trump explained that he refused to support the agreement that punishes the US alone but countries like China and India are not punished.
Since the 2016 Presidential election campaign, Trump has been determined to develop the US energy production sector, especially coal and oil.
The Trump administration has also regularly attended talks on the United Nations (UN) climate over the past three years to promote the use of fossil fuels.
