En este trabajo se analiza la desigualdad en la distribución mundial de emisiones de CO2 por sectores, para las regiones del PNUD en el año 2009, mediante el índice de Theil-Bourguignon, que permite descomponer la desigual¬dad total en la distribución por grupos de población. Cabe destacar que la mayor desigualdad en las emisiones de CO2 por sectores se produce en regiones que están formadas por países pobres o en vías de desarrollo. Asimismo, los resultados proporcionan una mayor importancia relativa al componente de desigualdad intragrupos. Posteriormente, se completa el estudio anterior mediante un análisis de sensibilidad de los componentes de desigualdad, utilizando la familia de índices de entropía generalizada. Dichos resultados señalan de nuevo el importante peso del componente intragrupos. In this paper, inequality of global distribution of CO2 emissions by sector is studied across the regions considered by the UNDP in the year 2009. Firstly, the research is carried out using the Theil-Bourguignon inequality index which can be decomposed into the within-group and the between-group inequality components. The greatest inequality in CO2 emissions by sector occurs in regions that are formed by poor or developing countries. The results show also that the within-group inequality component is the main contributor to the whole inequality value. Secondly, the study is completed using the family of Generalized Entropy indexes, where the within-group inequality component is the main contributor to the whole inequality value too.
