Global Carbon Dioxide Emissions Hit a New Record

Two years after 200 or so nations forged a new United Nations deal to protect the climate, output of the gases blamed for global warming surged to a record. Carbon dioxide emissions from energy use climbed 1.6 percent in 2017, with both emerging and developed economies contributing to the increase, according to BP Plc data published Wednesday. In the U.S., which intends to withdraw from the UN’s Paris accord, greenhouse-gas output fell for a third year.
