Donald Trump did not waste any time. As soon as he took office as the 47th President of the U.S., the Republican issued a flurry of executive orders remaking America’s policy. He announced the U.S.’s withdrawal from the Paris Agreement, which could be a blow to the global efforts to fight climate change. In 2016, when Mr. Trump won the election and had moved to withdraw the U.S. from the pact, the exit did not formally take place, thanks to the way the Paris Agreement rules were framed. However, this time, the U.S. can exit within a year of formally conveying this to the UN. The President has also swung America’s energy policy largely in favour of fossil fuels. He asked the Energy Department to resume allowing reviews of gas export facilities and instructed federal agencies to stop issuing leases and permits for all new wind projects pending a new environmental review.
