This paper reexamines the fundamental theory of Environmental Kuznets Curve (EKC) by an empirical study of per capita CO2 emission around the world. Here in this paper I have selected some developed and developing countries around the world and estimated the time series growth rate of per capita CO2 emission from 1950 to 2004 for each country. Results do not support the fundamental theory of pollution and economic development followed by EKC. I have compared at this juncture the share of total emission in global warming for both developed and developing countries. Result also shows that not only the growing poor developing nations, but also the rich developed countries have huge contribution in world CO2 emission and global warming.
