Did We Overestimate The CO2 Impact From China's Coal?
Researchers say previous trackers of China’s coal consumption might have overestimated how much CO2 the fuel released.By Evan Thomas | August 20, 2015
A recent study suggests China's coal-based carbon emissions are actually 40 percent lower than assumed.
Researchers analyzed coal specimens from 602 mines around China, and found more of China's coal is a lower-grade variety than what was used in previous emissions calculations. It produces more ash and has lower energy efficiency than purer coal, but also emits less carbon. (Video via BBC)
Lead researcher Dr. Zhu Liu said "The quality is not as good as developed countries, so if we use the same amount of coal, we overestimate the carbon content of the coal, and so we overestimate the carbon emissions.”
