The European Commission’s Joint Research Center published a report September 21 finding that global man-made CO2 emissions rose 5.8 percent in 2010 to the highest level ever recorded, 33 billion metric tons. The report, Long-Term Trend in Global CO2 Emissions, said the increase, 45 percent above 1990 levels, was mainly an emerging economy phenomenon, and concluded that increased energy efficiency and renewable energy use were not compensating quickly enough to reflect the growing demand for power and transport.
