摘要

China may struggle to cut carbon dioxide emissions to levels that prevent the worst effects of global warming, a United Nations study of 15 major emitters showed. The UN said per-capita emissions from burning fossil fuels need to fall to 1.6 tons in 2050 from 5.4 tons now across the 15 nations in order to stand even half a chance of capping the global average temperature rise at a safe level. It tasked research teams in each of the countries, including Germany, India, Japan and the U.S., to devise "deep decarbonization pathways" through to 2050. The Chinese team produced one that leads to 3.5 tons per capita, and the sum total of the 15 nations' efforts totaled 2.4 tons, according to the study by the UN's Sustainable Development Solutions Network.
