Abstract

This study revisits whether CO2 emissions converge in G18 countries over the period of 1950–2013. To work on this empirical analysis, we employ a more powerful quantile unit root test with per capita CO2 emissions. While conventional unit root tests fail to reject convergence in CO2 emissions in these G18 countries, quantile unit root test results demonstrate CO2 emissions converged in 5 of these G18 countries (i.e., Australia, Brazil, Canada, Germany, and India). Our empirical results have important policy implications for the governments of G18 countries to direct efficient and effective energy policies to reduce the CO2 emissions.
