Analyses of international inequality in environmental factors, such as the well-known CO2 per capita or the Kaya factors (that is, carbon intensity, energy intensity and affluence), have overlooked the effect that weighting vectors of distance functions and their time variations can have on the...

This paper analyzes the role of the energy transformation index and of final energy consumption per GDP unit in the disparities in energy intensity across countries. In that vein, we use a Theil decomposition approach to analyze global primary energy intensity inequality as well as inequality...
