Not true ! Please Check the Institute for Energy |Research at www.instituteforenergyresearch.org/fossil-fuels/global-energy-demand-and-fossil-fuel-consumption-rose-in-2018 and note the China, India and Other Developing Asian Countries such as Pakistan and Indonesia account for almost 60% of the world total in 2018 !
so what? That's apples and oranges data. You said population growth but are citing development and economic growth.
Even at that both China and India are in the low category of population growth. High population growth countries are mostly in Africa. Even Pakistan is about in the middle. Russia (#4), Japan(#5) and Germany (#6), all countries in the top 10 for total carbon emissions, have negative population growth.
How about some other statistics. While the world population may have more than doubled since 1967, the number of automobiles registered for the road has increased over 6 times. The number of aircraft flights has increased over 10 times in the same period.
What is automobiles and aircraft flights symptomatic of? Affluence! Both China's and India's carbon emissions reflect the rapid growth of a middle class. What defines the middle class? Affluence!
