Vladimir Putin may have grabbed headlines for lending China’s first lady his coat, but President Obama and President Xi Jinping made news of more substance at the APEC Summit, announcing a joint plan Wednesday to curb carbon emissions. Under the deal between the world’s No. 1 and 2 polluters, seen as essential to negotiating a new global climate agreement by 2015, the United States would emit 26 percent to 28 percent less carbon in 2025 than it did in 2005, and China would reach peak carbon emissions by 2030.
