As a result, the share of OECD countries in global C02 emissions declined from 55% in 1990 to 43% in 2010 (Figure 4.2). On the other hand, the share of Developing Asia jumped from 17% to 37% during the same period, and China alone more than doubled its share to 25% in 2010. While the respective contribution of India, ASEAN and other Asian countries to the global emission increase remains relatively modest, their collective contribution surpassed that of OECD countries as a whole.
