Spatial inequalities in territorial-based greenhouse emissions matter in terms of regulation, both at the international and subnational levels. This column decomposes these inequalities worldwide for the two major greenhouse gases over the period 1970–2008. Within-country inequalities are larger, and rising, while between-country inequalities are smaller and falling. Moreover, social tensions arising from the discrepancy between the distribution of emissions and the distribution of damages appear to be larger within than between countries, and larger for carbon dioxide than for methane.
