The ongoing rapid industrialization of the world's advanced developing economies means global emissions of heat-trapping gases will by the end of the decade exceed safe levels by far more than previously expected, according to a report published Friday.
The report from PBL Netherlands Environmental Assessment Agency said global greenhouse gas output will be at least 50.9 billion tones of CO2 equivalent a year by 2020, 2.5 billion higher than it estimated in 2010, and some 7-11 billion tones beyond levels needed to prevent runaway climate change.
