Atmospheric emissions

Cemig calculates its GHG emissions according to emission factors as established by the Brazilian GHG Protocol Program, which is a management and quantification tool for GHG emissions that is adapted to the Brazilian reality. Cemig seeks to improve quantification of its inventory of Greenhouse Gas Emissions by doing thorough research in the Company for new sources of emission to be introduced and calculated.

In 2011 new sources were identifi ed and duly incorporated into the inventory, which for the fi rst time was audited by an independent third party and verified on NBR 14064 Norm. Click here to access the Cemig’s Greenhouse Gas Inventory.

The Company’s thermal plants are responsible for the sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions. Only one of Cemig’s thermal plants burns fossil fuel in its operations – the Igarapé Thermal Power Plant, which currently is not fully operational. The other two thermal plants utilize blast furnace gases, tar and other waste gases generated in industrial processes at steel mills – the Ipatinga Thermal Power Plant and the Barreiro Thermal Power Plant.

Em 2011, as emissões de NOx foram de 87,42 toneladas, o que representa um aumento de 55% em relação a 2010. Já em relação ao SO2, foram emitidas 405,9 toneladas, 15% a mais que em 2010. In 2011, NOx emissions totaled 87.4 t. With regard to SO2, emissions were 406 t.
