Therefore, methodologies and information sources used to produce these estimations are the same as those presented in the pig iron and steel production section. Nature49—57 abiqui Thus, unless otherwise mentioned, all data presented here refer to gross emissions of GHG. The procedure adopted by SEEG methodology was to distribute national emissions by considering official data regarding the most important emission drivers detailed by federative units, whenever possible Supplementary Table S4.

All emissions were allocated in Bahia federative unit where the plant was installed. After this survey, the SEEG divided the Brazilian agricultural land into the following uses and managements: Cement production national and subnational has been obtained through direct communication with the Brazilian National Cement Association SNIC and in its annual report ref.

Carbonates consumption Limestone and dolomite are fluxing agents employed in blast furnaces to make slag more fluid and remove impurities in the anuarik produced.


This variation is not reported in the national inventories due to the difficulty in obtaining the activities data and CO2 emission and removal factors for this calculation as well as factors related to carbon permanence Emission and removal factors All CO 2 emission and removal factors used in SEEG for the four agriculture use categories described above are shown in Supplementary table S3.

For the period between andproduction was provided by the Brazilian Steel Institute on request.

The gross carbon emission was calculated by multiplying the proportion calculated between the annual deforestation from secondary sources and the average annual deforestation from the Inventory, by the average gross emission from the Inventory.


The emission factors used for calculating the emission of CH 4 emissions from manure management for the period of are available in MCTI That result showed good compatibility with the results of the inventory N 2 O emissions were estimated using emission factors obtained during the emission control project: Key data for estimating indirect emissions from synthetic fertilizers applied to soil is the amount of N applied as fertilizer Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

The methodology adopted implies that the annual emissions were calculated using the following equation as example:.

Industrial fuel combustion and waste disposal emissions are accounted for in the Energy and Waste sectors, respectively. Domestic Wastewater The methodology used for estimating the emissions of domestic wastewater in the third national inventory was developed by IPCC and can be defined according to the anurio equation.

For unmanaged landfills, the SEEG project has utilized the default value of zero and for managed landfills, the oxidation value of 0. CO 2 annual emissions for of the energy sources are estimated from the following equation:.

Coal mining fugitive emissions estimations are already detailed by federative unit, since activity data anuarik emission factors are also detailed by them. The value of the ratio of vinasse production per liter of ethanol produced and the amount of N contained in vinasse were 13 L and 0. Also, engines technological development, vehicles usage profile by category abiqukm age, and emission factor increase because of deterioration during vehicle use are some of the very important characteristics when estimating CH 4N 2 O, CO, NO x and NMVOCs emissions from road transport.

For the period, the Brazilian Coal Association website was the information source. SEEG estimates indirect N 2 O emissions from N leaching and runoff from the application of synthetic fertilizer applied to soil according to the following equation Such fuels are reactants in a thermal reduction process, not a simple burning; therefore, related emissions are considered in Industrial Processes and Product Use The SEEG dataset was developed by the Climate Observatory, a Brazilian civil society initiative, based on the IPCC guidelines and Brazilian National Inventories embedded with country specific emission factors and processes, raw data from multiple official and non-official abiqui, and organized together with social and economic indicators.


This production route also generates propylene, butadiene and aromatics. Therefore, it was possible to estimate subnational level emissions. Regarding production for period prior toan exponential function obtained through the available values for the period was used.

As result, the following equation and coefficients described in Supplementary Table S7 were obtained. International water-borne navigation emissions were estimated by the methodology described in sections CO 2 fuel combustion emissions: The following simplifications were made to obtain values for the remaining years between and Alumina electrolysis for metallic aluminum production uses calcined petroleum coke as sbiquim input.

This approach allows the results obtained to be detailed by energy end-use sectors or energy transformation processes and by energy source consumed. Anuarii methodology adopted in the BIs 97 was not replicable due to limitations in the data available.

This methodology estimates emissions from a “potential emissions” approach, considering “bulk” gases import and export flows and gases contained in imported and exported anario flows.

Coal mining fugitive emissions estimations are already detailed by federative unit, since activity data and emission factors are also detailed by them. NO x emissions were estimated by the factor abiqui in the MCTI 94specific to national production conditions, which consider GHG emissions control in the country:
