China burns more coal than previously reported

New York Times : China has released almost a billion tons more carbon dioxide into the atmosphere per year than previously reported, according to new data published by the country’s statistical agency. As a result, China, which is known for its extremely poor air quality, may have a much more difficult time meeting its goal of limiting coal consumption by 2030. The updated data are based on a 2013 economic census that revealed gaps in data collection, particularly from small companies and factories. Although China and many international agencies will have to adjust their databases, the new information does not change scientists’ estimates of the total CO₂ in the air because the estimates are based on direct measurement. Researchers will also need to figure out where the extra CO₂ is ending up—such as being absorbed by carbon sinks like forests and oceans. The revelation comes just before the 2015 United Nations Climate Change Conference , to be held in Paris 30 November to 11 December, during which delegates hope to reach a new international agreement on climate and set a limit on global warming.
