- Global warming is a tangible reality. Green House Gases (GHGs) are the main cause of this world-wide phenomenon. Since the middle of last century there has been an abrupt increase in GHG emission because of high anthropogenic pressure and fast economic growth in many parts of the world. Because of environmental concern all over the world there have been concerted efforts to cope up with this problem. Myriads of empirical studies were carried out and policy decisions were taken to contain CO2 emission. This study is also undertaken to examine that which of the factors out of population growth, economic development and technological advancements cause more damage in terms of CO2 emission. Then behavior of the most harmful factor is analyzed in Environmental- Kuznets ？ Curve to search a solution to this problem. This is accomplished through widely used models viz. IPAT model and Environmental ？Kuznets ？Curve (EKC). The impact on environment in terms of CO2 emission is measured in 21 economies of the world comprising of seven in each three categories viz. developing, developed and least developed economies. The decompositionidentity of IPAT model is used in this study to identify the most harmful factor. It is found that the economic growth i.e.GDP per capita iscausing more damage to the environment in terms of CO2emission than population growth in
