54 CO2 Emission / By solid fossil combustibles<br />

Unit<br />

1000 t<br />

Concept<br />

Estimated volume of carbon dioxide emission (CO2) originating from metallurgic<br />

charcoal, vapour charcoal, tar and coke.<br />

Comments<br />

According to the Report on Carbon Emission of the Climate Changes Convention/<br />

MCT, a calculation of CO2 emission of solid fossil combustibles was made based<br />

on the “top-down” methodology, developed by IPCC (Intergovernmental Panel<br />

on Climate Change), which considers that, once introduced into the national<br />

economy, the carbon contained in the combustible is either released into the<br />

atmosphere or is retained in a specific manner (i.e., through combustible supply<br />

increase, by absorption of certain non energetic products or by its own retention<br />

partially inoxidated). In calculating the CO2 emission, a balance is made involving<br />

primary combustible domestic production, the liquid import of primary and<br />

secondary combustibles internal variation of such combustible supplies.<br />

55 CO2 emission / By cement production<br />

Unit<br />

1000 t<br />

Concept<br />

Estimated volume on carbon dioxide emission (CO2) originating from cement<br />

production, related to the production of clinker (a mixture of calcareous rocks<br />

and silicate ), cement’s main component.<br />

Comments<br />

According to the Report on Carbon Emission of the Climate Changes Convention/<br />

CCC of the Ministry of Science and Technology - MCT, the conversion EF factor<br />

was used, clinker = 0.5071 which correlates the clinker production to the CO2<br />

emission.<br />

56 Sulfur dioxide emission (SO2)<br />

Unit<br />

Gg<br />

Concept<br />

Estimated volume of sulfur dioxide emission (SO2) originating from industrial,<br />

chemical and petrochemical processes.<br />

Comments<br />

According to the Report on Carbon Emission of the Climate Changes Convention/<br />

CCC, the method of calculating SO2 emission correlates, through emission<br />

coefficients, the gases emanating from the production processes with the<br />

quantities produced.<br />

57 Emission of nitrogen oxides (NOx)<br />

Unit<br />

Gg<br />

Concept<br />

Estimated volume of nitrogen oxide emission (NOx) originating from chemical,<br />

industrial and petrochemical processes.<br />

Comments<br />

According to the Report on Carbon Emission of the Climate Changes Convention/<br />

CCC, the method used to calculate NOx emission correlates, through emission<br />

coefficients, the gases emanating from the production processes with the<br />

quantities produced.<br />
