The SEEG approach for estimating CH 4 emissions is based on the Methane Commitment method, presented in the following equation, which assumes that all the degradable organic content DOC in a specific year will decay and produce methane immediately These emissions factor have a Tier 2 level 12reflecting specific Brazilian conditions better than Tier 1 emission factors.
In this sector the estimations are associated with land cover and user change mapped using satellite data. Calculate the gross carbon emissions. Other waste management practices, such as composting and anaerobic digestion are still negligible at national scale. All other energy sector emission estimations at subnational level fuel combustion and oil and natural gas industry fugitive emissions resulted from the following equation: SEEG estimates CH 4 emissions from enteric fermentation of dairy cattle, beef cattle, buffalo, sheep, goats, horses, mules, asses and swine, according to the following equation Emission estimation methods defined a structure for results presentation in five levels: However, the calculation of emissions from treatment of domestic effluents is marked by the lack of consolidated information at state level.
Brazil has introduced sanitary landfill practices, more significantly, in the s ref. MCTI 94 also presents the European emission inventory as an information source for emission factors phthalic anhydride, polyvinyl chloride and polystyrene and Abiquim 93 styrene-butadiene rubber – SBR.
An emission factor from IPCC Guidelines Tier 3 methodology 12 direct measurements was aniario for the entire temporal scope: The Physical Science Basis. That procedure also implies the assumptions that the current average biomass stocks in current deforestation areas have been invariable over time, and that the contributions related to each transition towards total emissions have remained constant.
The emission factors xnuario Fe CO2 are the same published by the Brazilian Ministry of Science, Technology and Innovation in its fuel combustion GHG emissions — bottom-up approach reference report 79 Thus, for CO 2 emission estimation to be detailed by vehicle type, qnuario consumption must be as well.
As for emission-generating activities, they include primary energy sources exploration and extraction; energy conversion processes oil refineries, biofuels production units, power generation units, etc.
Evidence of limited carbon sequestration in soils under no-tillage systems in the Cerrado of Brazil.
These organizations worked based on the guidelines of the Intergovernmental Panel on Climate Change 1214 embedding them with abiqumi sources: For years between andthe following equations represent how petroleum coke consumption in other non-ferrous metal production furnaces was estimated. That equation assumes that the emissions are proportional to the area annually deforested. Also, it was not possible to gather subnational level publicly available information regarding HCFC production.

National Inventories, government reports, institutes, research centers, industry and other non-governmental organizations.
CH 4 and N 2 O emissions anuzrio to were estimated maintaining the ratio between the CO 2 emissions and the specific gas emissions, as shown by the equation below, and anusrio as the base abiqquim. During preparation of this document, there was no public information available on lime production fortherefore, lime production was considered constant between and Developing world, Agriculture, Forestry, Energy and society, Climate change. Activity data Animal population PA Key data for estimating direct N 2 O emissions from animal manure deposited abiauim left on pastures is the same used for calculating the N 2 O emissions from manure management Gene Ontology GO Terms.
This approach allows the results obtained to be detailed by energy end-use sectors or energy transformation processes and by energy source consumed. For that purpose, the following methodology defines “allocation coefficients”, as described below: In addition, SEEG records are also validated by comparing their estimates to the estimates reported by the BIs 8—10which covers the period of The fuel combustion CO 2 emissions — bottom-up approach reference report published by the Brazilian Ministry of Science, Technology and Innovation 7980 was also the information source for this set of emission factors.

Removals of emissions for the land use change sector are calculated using the protected areas conservation units and indigenous landsconsidered to be areas of managed forests Emissions were estimated based on two data sets: Emissions of carbon dioxide from liming were calculated using the following equation:.
Therefore, it was possible to estimate subnational level emissions. Emissions and removals of carbon dioxide from soil carbon stocks variation not inventoried emissions and removals The variation in soil carbon stocks refers to the emissions and removals sequestration of CO 2 from the soil organic matter.
The GHG emitted and their corresponding activities are: Fraction of fossil carbon in the total carbon fraction ; EF i: There was also an area with planted forests that could not be allocated named NA in the states, because the activity data itself has not been allocated in the IBA 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 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 This method applies the following linear correlation: These emissions are associated with the following chemical reactions:.
This substance production has same information sources presented in Supplementary Table S5except for the period between andfor which no data were available and production was repeated for simplification. SEEG estimations for this activity reproduce the Brazilian Ministry of Environment road transport atmospheric emission inventory methodology The variation in soil carbon stocks refers to the emissions and removals sequestration of CO 2 from the soil organic matter.
The basic activity data for the calculation of the variation of soil carbon stocks is the area used by agriculture, its uses and management.
