China considers nationwide carbon trading from 2017

The country is responsible for around 30% of the world's total carbon emissions. 

"From 2017, China intends to introduce nationwide trading of carbon allowances. At 10.33 trillion tons of carbon per year, emissions there are around twice as high as the 5.3 trillion tons generated by the US - the second-largest polluter country", notes Commerzbank. 

In the long term, the initiatives aimed at limiting carbon emissions are likely to have serious implications for the energy sector. One obvious consequence for example would be reduced growth in global coal demand.
