ABSTRACT. This paper analyzes the eco-efficiency of a set of eighteen companies from several economic sectors, listed in the Brazilian Green House Gas Program (GHG). The central objective was to respond to the environmental impact caused by the economic activities of these sectors by calculating their eco-efficiency. This is a highly relevant subject for comparing the sectors that most affect the environment in the generation of its wealth. As for the objectives, it is considered an exploratory study; And with regard to procedures, a documentary and ex-post facto work. In order to calculate the eco-efficiency of each company, the Additional Values Statements (VAS) and environmental impacts were used, which were extracted from the inventories of greenhouse effect gases, equivalent to carbon dioxide, in tons. For a comparison of very disparate results, these ecoefficiencies were changed in logarithms in the base 10. The results show that the petroleum, chemical, civil construction and mining sectors were the ones that presented the smallest ecoefficiencies, already expected. Companies that generate products with higher aggregated values produce less environmental impacts.
