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...

Recently, White (2007) analysed the international inequalities in ecological footprints per capita (EF hereafter) based on a two-factor decomposition of an index from the Atkinson family (Atkinson, 1970). Specifically, this paper evaluated the separate role of environment intensity (EF/GDP) and...
