Inequality of Carbon Intensities Across OECD Countries

This study recommends the use of Theil's second measure to investigate international carbon intensity disparities. This index permits disparities to be broken down within and between groups of countries in a reliable style. An analysis of OECD countries for 1980-2011 shows some basic points: first, drop in carbon intensities disparities is attributable both to within-group and between-group inequality components; second, between-group inequalities are presently the key contributor to the inequality; and, further investigation on within-group inequalities divulges the significant explanatory role played by North American, and Central and South American countries.
