Decomposing Energy-Related CO2 Emissions in Tunisia Using the LMDI Approach

Abstract

AbstractThis paper aims to identify the factors that contribute the most to the change in Tunisian energy-induced carbon emissions during the 1990–2012 period. To that end, an LMDI decomposition analysis is applied on five final energy-use sectors: industry, agriculture, transport, tertiary, and the residential sector. The results indicate that GDP growth is the main factor driving the growth of CO2 emissions, while the reduction in energy intensity and structure effects contributes to reducing CO2 emissions in the economic sectors (industry, transport, agriculture, and tertiary). For the residential sector, a change in energy intensity is the main driving force behind the change in CO2 emissions. A better understanding of energy-induced CO2 emissions by all sectors, how they change, and the sources of these changes would have important policy implications in reducing CO2 emissions and reaching the country's targeted 1.5–2 °C global levels. To the author, no study has undertaken a decomposition analysis of energy-induced carbon emissions of both the economic and residential sectors by examining detailed sector-specific raw data.KeywordsCarbon dioxide emissionsInfluencing factorsDecomposition analysisLMDITunisia
