In June, US President Donald Trump, who repeatedly criticized the Paris accord during his election campaign as potentially dangerous for the US economy and employment, announced the country’s exit from the agreement, expressing readiness to renegotiate the agreement under new terms that would be more favorable for the United States.
The Paris climate agreement was adopted in December 2015. Signed by over 190 countries and ratified by nearly 150, the accord came into force in November 2016. According to the document, all parties to the agreement should reduce greenhouse gas emissions in order to maintain the increase in average global temperature at below 2 degrees Celsius above pre-industrial levels.
