In that case, why are Chinas emissions hoing up, when its population is shrinking?

Population growth matters, but the real issue is consumption. Intresstingly people have fewer children in urbaized socitied, when they have all basic material needs meet and womens rights are improved. So we just have to meet everybodies needs to a reasonable level and have to reduce emissions. Population is solving itsrlf at that point. If we did that global population would peak before 2050 and fall to about 6billion by the end of the century.
