31  Calculating emissions avoidance abatement for a project area for a reporting period
 (1) The total emissions of greenhouse gases avoided for a project area in a reporting period r, Er, in tonnes CO2-e, are worked out using the following equation:
  equation 6

where:
 is the baseline emissions of CH4 for the baseline for the ith CEA in the project area, in tonnes CO2-e, worked out using equation 7.
 is the baseline emissions of N2O for the baseline for the ith CEA in the project area, in tonnes CO2-e, worked out using equation 8.
is the baseline emissions of CO2 for the baseline for the ith CEA in the project area, in tonnes CO2-e, worked out using equation 9.
 is the emissions of CH4 for the ith CEA in the project area in the reporting period, in tonnes CO2-e, worked out using equation 10.
 is the emissions of N2O for the ith CEA in the project area in the reporting period, in tonnes CO2-e, worked out using equation 11.
is the emissions of CO2 for the ith CEA in the project area in the reporting period, in tonnes CO2-e:
 (a) if the land type in the CEA has not changed since the baseline—has the same value as the value for worked out using equation 9;
 (b) otherwise—0.
 is the transition emissions of CO2 released from changes in live vegetation biomass for the ith CEA in the project area in the reporting period, in tonnes CO2-e, worked out using equation 12.
i is a CEA in the project area.
 (2) The emissions of CH4 for the ith CEA in a project area for the baseline, , in tonnes CO2-e, are worked out using the following equation:
  equation 7

where:
 is the global warming potential of methane, specified in the NGER Regulations.
i is a CEA in the project area.
 is the mass of CH4, in tonnes per hectare, emitted from the th CEA in the project area from baseline land types, determined using BlueCAM.
ACEAi,r is the area, in hectares, of the th CEA in the project area in the reporting period.
 (3) The emissions of N2O for the th CEA in a project area for the baseline, , in tonnes CO2-e, are worked out using the following equation:
  equation 8

where:
 is the global warming potential of nitrous oxide, specified in the NGER Regulations.
i is a CEA in the project area.
 is the mass of N2O, in tonnes per hectare, emitted from the th CEA in the project area from baseline land types, determined using BlueCAM.
ACEAi,r is the area, in hectares, of the th CEA in the project area in the reporting period.
 (4) The emissions of CO2
