Another point of debate is the degree to which newly developed economies such as India and China should be expected to constrain their emissions. China's gross national CO2 emissions are expected to exceed those of the U.S. within the next few years, and may have already done so according to a 2006 report. China has contended that it has less of an obligation to reduce emissions since its per capita emissions are roughly one-fifth that of the United States. India, also exempt from Kyoto restrictions and another of the biggest sources of industrial emissions, has made similar assertions. However, the U.S. contends that if they must bear the cost of reducing emissions, then China should do the same.
