United States and the Paris Agreement

In April 2016, the United States became a signatory to the Paris Agreement on climate change mitigation, and accepted it by executive order in September 2016. President Barack Obama committed the United States to contributing US$3 billion to the Green Climate Fund. On June 1, 2017, U.S. president Donald Trump announced that the United States would cease all participation in the 2015 Paris Agreement on climate change mitigation, contending that the agreement would "undermine" the U.S. economy, and put the U.S. "at a permanent disadvantage".
