The (De-) carbonization of urbanization, 1960-2010

We investigate the potentially changing effect of urbanization on per capita and per unit of GDP carbon dioxide emissions for 69 nations from 1960 to 2010. We examine the effect of urbanization, measured as the percent of nation's population residing in urban areas, for the overall sample as well as for smaller regionally-defined samples of nations. The results of two-way fixed effects longitudinal models for both outcomes highlight that the changing effects of urbanization on national carbon emissions throughout the world regions are far from monolithic, and these differences are hidden by the analyses of emissions for the overall sample. We provide tentative explanations for our regionally-specific findings, and conclude by emphasizing the need for more nuanced urban data and future research to increase our collective understanding of the carbon emissions / urbanization relationship.
