Emissions factors
The emission factors are calculated from the carbon stock indicated in the following map:
File:
E:/dev/impact/IMPACT/DATA/congo_training/emissions/1_cartes de changements/Sangha_recentchangesCongo_eq_area.tif
For calculating the degradation emissions in option A, a proportion of 30.0% of the carbon stock is used. Option B is using another approach.

The reporting of areas affected by deforestation and forest degradation and their associated CO2 emissions is done based on the classification of the grid of minimum forest units (MFU). Only the MFUs classified as deforested or degraded are considered for the reporting. The area of deforested or degraded MFUs is available in the Excel version of the report.
Two options are available to the users. Option A considers the total forest cover of the MFUs while option B uses only the pixels that are detected as tree cover loss in deforested or degraded MFUs. The choice between option A and B is left to the user, according the requirements of the study and of the quality of the tree cover loss data at his/her disposal. In case of tree cover loss maps that are prone to miss small scale disturbances of tree cover, the user is advised to choose option A.Area of forest at the start of the analysis
Total area of forest (MFUs area are adjusted for non-forest presence) at the start of the period 1 (2011): 5579926.0 haOPTION A – Minimum Forest Unit
In option A, the areas and emissions are calculated according to the entire tree cover content of the MFU (the MFU area is adjusted for non-tree cover presence). For deforestation, the entire carbon content of the MFUs is converted in CO2 emissions. For forest degradation, a proportion of the carbon content of the MFUs is converted in CO2 emissions. The proportion is indicated by the user as the "Proportion (%) of carbon stock emitted by degradation". For option A, a proportion of 30.0% of the MFU carbon stock is used for calculating the forest degradation emission factors.

Option B – Pixels of tree cover loss
In option B, the areas and the emissions are calculated according to count of tree cover pixels loss in deforested or degraded MFUs. The emissions are calculated in the same way for deforestation and degradation. In both case, only the carbon content present in the pixels of tree cover loss is converted in CO2 emissions. | Total

Exceptions: area excluded from the analysis
The following table indicates the area chosen by the user to be excluded from the analysis above. The user has to indicate the period (1 or 2) to which each exception refers to. The total biomass in tC of the area is reported, not its value in equivalent CO2.| Exception code | Area (ha) | Carbon stock (tC/ha) |
