China’s President Xi Jinping said Wednesday that his country plans to reduce its greenhouse gas emissions by at least 7% to 10% over the next decade. His landmark pledge, in a video address Wednesday to the U.N. General Assembly, came a day after President Trump called climate change “the greatest con job ever perpetrated on the world.”

President Xi Jinping: “Green and low-carbon transition is the trend of our time. While some country is acting against it, the international community should stay focused on the right direction, remain unwavering in confidence, unremitting in actions and unrelenting in intensity.”
