What's next in US withdrawal from Paris Climate Agreement

Trump announced his decision to withdraw on Thursday.

While Trump does have the power to pull the U.S. out of the agreement, it will not be able to happen overnight. Any member must wait three years before they are eligible to withdraw, which is stipulated under Article 28 of the accord.

If Trump follows through on his promise, experts agree that greenhouse gas emissions and global temperatures will increase more precipitously than they would have if the U.S. remained party to the accord.

However, the Sierra Club released an estimate that 60 percent of the emissions reductions promised under the Paris agreement could be met by local initiatives were they to replace coal with clean energy. This afternoon, 61 U.S. mayors released a statement reiterating their dedication to “adopt, honor, and uphold the commitments to the goals enshrined in the Paris Agreement.”

Advocacy organizations are also preparing to use lawsuits as a method to delay the dismantling of climate-related programs domestically. Michael Gerrard, director of the Sabin Center for Climate Change Law at Columbia University, tweeted that “the law will need to play a major role in pushing back against the attempted dismantling of our environmental and health protections.”
