The sociology of ecologically unequal exchange and carbon dioxide emissions, 1960-2005.

The author engages the sociological theory of ecologically unequal exchange to assess the extent to which levels of per capita anthropogenic carbon dioxide emissions are a function of the "vertical flow" of exports to high-income nations. Results of cross-national fixed effects panel model estimates indicate that levels of such emissions are positively associated with the vertical flow of exports, and the relationship is much more pronounced for lower-income countries than for high-income countries. Additional findings suggest that the observed relationship for lower-income nations has grown in magnitude through time, indicating that structural associations between high-income and lower-income countries have become increasingly ecologically unequal, at least in the context of greenhouse gas emissions. These results hold, net of various important controls.
