A decomposition analysis of energy related CO2 emissions is carried out for 33 world countries. The data pertain to the period 1995-2007. The methodology used is the Index Decomposition Analysis that allows to investigate the contribution of the following factors: (i) changes in abatement technologies, fuel quality and fuel switching; (ii) changes in the structure and efficiency of the energy system; (iii) relative ranking of a country in terms of the total Gross Domestic Product (GDP) generation and (iv) changes of the country specific total economic activity. The World Input Output Database (WIOD) has been used together with OECD data on GDP. Results show that economic growth has been the main driving factor of energy related CO2 emissions increase. However, in fast developing countries like India and China, an important contribution has also been the increasing role that these economies are playing in the global economic panorama. Improvements on energy efficiency have been the main element contributing to reduce the overall CO2 emission increase in all the countries considered in this study.
