Contribution of manufacturing subsectors in the variation of CO2 emissions from the use of fuel in San Luis Potosí, México

Abstract

The analysis of the variation of carbon dioxide (CO₂) provides useful information for reduction alternatives. In the present study, a decomposition of the factors that determine the annual variation of CO₂ emissions was performed, identifying the effect of each of the manufacturing subsectors of San Luis Potosí, Mexico, during the period 2000-2012. The Log Mean Divisia Index (LMDI) approach was used to identify the disaggregated contribution of manufacturing subsectors in the variation of emissions, according to the Kaya equation. Energy intensity and the manufacturing Gross Domestic Product (GDP) were the factors with a greater effect on the variation of CO₂, with contributions of 53.85% and 37.32% respectively. The subsectors of manufacturing products based on non-metallic minerals, primary metals industry, and food industry are mainly affecting the dynamics of the factors identified.
