A hipótese da curva de Kuznets ambiental global: uma perspectiva econométrico-espacial

With the aim of checking the relationship between income growth and global warming, the present study analyzes a global environmental Kuznets curve for a sample of 187 countries through a spatial econometric approach. An EKC for conventional per capita CO2 emissions was run on per capita income and its square value, controlling for per capita exports, per capita energy consumption, a dummy variable indicating the countries that ratified the Kyoto Protocol. The results suggested that there is evidence of an inverted U shaped EKC, that is, growth reduces the environmental impact of economic activity. However, the incorporation of a cubic term for per capita income shows that emissions eventually return to increase at a very high level of growth, leading the estimated EKC has an N shape. Furthermore, another finding was that there are evidences that countries that ratified the Kyoto Protocol reduced significantly their per capita CO2 emissions.

Avaliação da intensidade de emissões de CO2 setoriais e na estrutura de exportações: um modelo interregional de insumo-produto São Paulo/restante do Brasil

This paper quantifies CO2 emissions resulting from the consumption of energy fuels, assuming a hybrid interregional input-output analysis for the regions of Sao Paulo and rest of Brazil, using the matrix of 1996. We calculated the intensity of carbon dioxide emissions to 15 sectors, identifying the portion of total emissions due to the final demand and consumption intermediated. Moreover, the key-sectors emissions were calculated by elasticities, identifying the sectors of Agriculture, Steel, Food and Beverages, Other Sectors and Transport in the two regions analyzed. Finally, was also analyzed the amount of CO2 incorporated in exports, noting that the agenda of Brazilian exports is largely pollution intensive.
