Efeitos tecnológicos e estruturais nas emissões brasileiras de CO2 para o período 2000 a 2005: uma abordagem de análise de decomposição estrutural (SDA)

Abstract

The aim of this paper is the measurement of the changes in productive structure upon carbon dioxide emissions in Brazil. The method used was the Structural Decomposition Analysis. This is a method derived from Input-Output allowing more detail in the decomposition of technological change and demand of the production process. Thus using a database of emissions from the balance of emissions, equivalent and final energy and IBGE input-output matrices, both for 2000 and 2005 and adapted for 15 Brazilians economic sectors. The main results indicate that the sectors of transport, steel and food and beverages are those that were more likely to increase emissions, when considered variation in final demand, and industry sectors of cement, non-metallic minerals and pulp and paper stand out for reduction of emissions due to technological change.
