According to the methodology used in this report, emissions for the period between and were estimated through linear regression of emissions between and It was verified that during the period from tothere was a high correlation between the total area deforested and the total emissions of CO 2 equivalent Supplementary Figure S It was verified that during the period from tothere was a high correlation between the total area deforested and the total emissions of CO 2 equivalent Supplementary Figure S All other energy sector emission estimations at subnational level fuel combustion and oil and natural gas industry fugitive emissions resulted from the following equation: Emission Factor The emission factor of organic load per unit produced is available in the reference report, for each industrial sector, as well as data for the maximum CH 4 producing capacity, default from the IPCC 96and information on the methane recuperated for the period of Key data for estimating direct N 2 O emissions from animal manure deposited and left on pastures is the same used for calculating the N 2 O emissions from manure management The tables from the Inventories that contain the net emissions of each one of the Brazilian biomes were used as reference.
Therefore, long term datasets can provide meaningful data for evaluating the performance and trends of economic sectors of a given country and increase capacity to evaluate risk management strategies 3.
Magnesium production Brazilian metallic magnesium production is based on a thermal reduction process and uses dolomite as an input material.
Traditional nitric acid HNO 3 production is based on ammonia catalytic oxidation with air, followed by product oxidation with water Ostwald processthese reactions release NO x emissions during processing. During combustion, carbon C stored in the fuel is oxidized and released as carbon dioxide CO 2.
SEEG initiative estimates of Brazilian greenhouse gas emissions from 1970 to 2015
Emission Factor The emission factor of organic load per unit produced is available in the reference report, for each industrial sector, as well as data for the maximum CH 4 producing capacity, default from the IPCC 96and information on the methane recuperated for the period of Emission factors The emissions factors for the land use change sector are represented by increments or average losses of carbon stocks per abquim of area undergoing change. Energy sector emissions in SEEG database are also detailed by federative units.
Carbon stock tC ; EF residues: Emissions were estimated based on two data sets: Regarding production for period prior toan exponential function obtained through the available values for the period was used. anuaeio
Therefore, methodologies and information sources used to produce these estimations are the same as those presented in the pig iron and steel production section. Therefore, it was possible to estimate consumption exclusive in blast furnaces. For periods, coefficients were obtained from linear interpolation considering available data forand. Nitrous oxide emissions from animal manure applied to soil as fertilizer SEEG estimates N 2 O emissions from animal manure applied to soil as fertilizer, according to the following equation Dolomite consumption During the thermal reduction process, dolomite suffers a chemical reaction similar to calcination, generating CO 2 emissions.
According to MCTI 97beforemeasures of recovering and burning CH 4 in a flare or an energy device were not significant in Brazil. Ethylene oxide production In Brazil, ethylene oxide is produced by ethylene direct oxidation with air. Calculation of GHG emissions: Lime type chemical composition and consequent emission factors used are the same as in MCTI In this process, there are carbon dioxide and methane emissions.

Emission estimation methods defined a structure for results presentation in five levels: As shown in Supplementary Figure S5in blast furnaces at high temperatures, these minerals decarbonize, which generates CO 2 emissions. Default values to quantify ahiquim methane production capacity B 0 and national data to establish an average per capita degradable organic component D dom were used in anuarip BIs.
For the period, the Brazilian Coal Association website was the information source. As result, the following equation and coefficients described in Supplementary Table S7 were obtained.
SEEG methodology assumed that the ratio between petroleum coke consumption as the anode in aluminum production and aluminum production remained constant in the years for which this value is not known. To quantify emissions associated with treatment and discharge systems of abiquom effluents for the period ofthe SEEG initiative reproduced the methodology ankario by the MCTI, which in turn, is based on the methodology developed by the IPCC 12 Estimations of GHG emissions basically rely on the multiplication of an activity data and a respective emission factor That equation assumes that the emissions are proportional to the area annually deforested.
Fuel consumption estimated by the inventory is adjusted for each fuel type, based on road transport fuel consumption published in Anuatio 65through annual correction factors of the usage variable U. Steel production data for and were obtained from spreadsheets provided by the Ministry of Mines and Energy.
In the oil and natural gas industry, fugitive emissions occur in three activity sets as listed below Allocation criteria direct linked to the related emission factor. The average emissions factors were calculated based on all of the raw emissions generated in MCTI 9 Table 4according to the procedure described above.
The methodology adopted implies that the annual emissions were calculated using the following equation as example:. The methodological procedure of this inventory will not be described in detail in this article because of its extent; however, it is consistent with IPCC Guidelines Tier 2 methodology 12 and the two most important general equations applied will be shown below. These BIs are based on the IPCC Guidelines 1214but already embedded with several country specific data, which has enabled most estimations to have a Tier 2 level of precision 10 The following equation was utilized:.
