China, the world’s largest source of planet-warming carbon emissions, may have hit the peak it promised in the Paris climate accord well before its 2030 timetable.
That’s the conclusion reached by scientists who looked at the country’s estimated carbon output between 2007 and 2016, as the country’s rapid industrialization slowed and its consumption of coal declined.
Guan and his colleagues estimate Chinese emissions of carbon dioxide and other greenhouse gases topped out in 2013 at about 9.5 billion tons.
The numbers declined to about 9.2 billion tons in 2016, the last year of the study.
After nearly three decades of rapid growth, China passed the United States to become the world’s largest source of carbon emissions in 2006.
The Chinese experience can show those large, still-developing nations that they too can bring prosperity to their people without an outsized carbon footprint. “
Even if China hasn’t hit its peak emissions already, it’s still expected to hit that goal and most likely hit it early, Li said. »
