Are the determinants of CO2 emissions converging among OECD countries?

This paper studies convergence in CO2emission intensity (CO2 emissions over GDP) among OECD countries over the period 1960-2008 based on its determinants, namely, energy intensity (energy consumption over GDP) and the so-called carbonisation index (CO2 emissions over energy consumption). We apply th...

Description
Summary:This paper studies convergence in CO2emission intensity (CO2 emissions over GDP) among OECD countries over the period 1960-2008 based on its determinants, namely, energy intensity (energy consumption over GDP) and the so-called carbonisation index (CO2 emissions over energy consumption). We apply the Phillips and Sul (2007) methodology, which tests for the existence of convergence clubs. Our results highlight that differences in emission intensity convergence are more determined by differences in convergence of the carbonisation index rather than by differences in the dynamic convergence of energy intensity. ► We study convergence in CO2emission intensity and its determinants. ► The Phillips and Sul (2007) approach is used to test for convergence clubs. ► We find greater convergence within clubs in the energy intensity ratio. ► More regulation is required to foster convergence in the carbonisation index.
