Like a smoker who stay fresh try on to give up but sneaks a retarding force when he thinks nobody ’s looking , China is tardily weaning itself off ember . Last winter , the Chinese governmentreleased preliminary statisticsshowing that its ember consumption had neglect 2.9 percentage in 2014 . But that figure may be obfuscating the truth about China ’s ember habit — and about how quick its carbon emissions are declining .
Astudypublished this week in Nature Climate Change convey a penny-pinching looking at what China ’s “ historical ” 2014 reduction in coal intake actually think of . When the Chinese National Bureau of Statistics reported that 2.9 percent figure , the International Energy Agency used it to estimate that China ’s overall carbon emission had strike by 1.5 pct . Because China accounts for nigh a third of all C emissions worldwide , this ram humanity ’s collective carbon paper footprint down by 0.2 percent . Progress !
Well , not exactly . As Jan Ivar Korsbakken , a senior mood economics research worker at CICERO repoint out , a reduction in the amount of coal a country consume by weight unit does n’t necessarily render into low-toned emissions . That ’s because you have to account for the energy cognitive content of the ember , too — some ember is more carbon - copious than other coal . In the typeface of China , coal consumption fell by 2.9 pct in 2014 , but the overall energy tightness go up .
It ’s like trying to lose system of weights by cutting your overall food intake , but in the procedure , trading fruits and veggies for cheeseflower and burnt umber . When Korsbakken and his co - author took this detail into account , they establish that China ’s carbon copy emissions really increase in 2014 , by 0.8 percentage .
“ The subtext here is whether there are square difference between reported and real emissions , ” Rob Jackson , an Earth scientist at Standford University who was not involved with the sketch say Gizmodo in an email . “ Even if China ’s ember use miss 2.9 per centum in 2014 , you ca n’t equate this with a interchangeable bead in CO2 discharge . ”
China does not have a majuscule track record when it come to reporting energy use : Its statistics are routinely revise , and often turn back tremendous gaping holes . But given the rural area ’s outsized influence on global carbon emissions , those statistic matter a lot . For case , it number to brightness last fallthat China was burning up to 17 percent more coal than the government had antecedently claimed , an amount that equated to 70 percent of the United States ’ total annual coal consumption . China is n’t winning any climate plunder with an erroneousness perimeter of 20 percent .
On a undimmed government note , it seems that China ’s overall ember usage really is falling . The country report even steeper coal reductions—3.7 pct — in 2015 , which , Korsbakken and his colleagues conclude , “ make it likely that the stagnancy in coal use in 2014 was veridical and the start of at least a poor - terminus movement . ” At the same clock time , China remain tomake major investment in wind and solar technology .
The interrogation is whether China can decarbonize fast enough to live up to theambitious climate pledgeit made in Paris last December . And whether the rest of us can conceive it if we say it .
