CO<inf>2</inf> emissions convergence among 10 South American countries. A study of Kaya components (1980–2010)

Abstract:

This paper analyzes the convergence process in CO2 emissions per capita among 10 South American countries from 1980 to 2010 based on their Kaya components, namely, gross domestic product (GDP) per capita, energy intensity and CO2 intensity. This work tries to find out whether a set of countries of a given region share common convergence patterns in CO2 emission per capita and in its driving forces. First, a descriptive statistical analysis is carried out, and then Phillips and Sul methodology is applied to test the existence of convergence clubs in the pathway of evolution of each Kaya component. An analysis of inequality was also performed, considering three exogenous groups of countries. The results show that the region, as a whole, does not present a global convergence pattern regarding CO2 emissions per capita; however, the evidence suggests the formation of various convergence clubs for each Kaya component and even for the Kaya identity as a whole.
