27Steps to calculate net abatement amount

27  Steps to calculate net abatement amount

 (1) BlueCAM must be used to make the calculations in this Part for a reporting period for each CEA in a project area for the project.

 (2) Subsection (3) applies if:

 (a) a reporting period is the first reporting period for the project; or

 (b) a CEA includes land that has not previously been included in a CEA for a reporting period for the project.

 (3) The project proponent for the project must calculate the following for a CEA and for the land type for land in the CEA that existed at the end of the baseline period:

 (a) CH4 emissions for the end of the baseline period;

 (b) CO2 and N2O emissions for the end of the baseline period;

 (c) aboveground live biomass and belowground live biomass carbon stock for the end of the baseline period;

 (d) soil carbon stock for the end of the baseline period.

 (4) Subsection (5) applies to a CEA if:

 (a) a reporting period is not the first reporting period; and

 (b) the CEA only includes land that has been included in a CEA for a previous reporting period for the project.

 (5) The project proponent for the project must calculate the following for a CEA and for the land type for land in the CEA that existed at the end of the previous reporting period:

 (a) CH4 emissions for the previous reporting period;

 (b) CO2 and N2O emissions for the previous reporting period;

 (c) aboveground live biomass and belowground live biomass carbon stock for the previous reporting period;

 (d) soil carbon stock for the previous reporting period.

 (6) The project proponent for the project must calculate the following for a CEA and for the land type for land in the CEA that existed at the end of the reporting period:

 (a) CH4 emissions for the reporting period;

 (b) CO2 and N2O emissions for the reporting period;

 (c) aboveground live biomass and belowground live biomass carbon stock for the reporting period;

 (d) soil carbon stock for the reporting period;

 (e) CO2 emissions associated with live biomass loss from ecosystem transition (ETR) that occurred during the reporting period;

 (f) CO2 emissions associated with loss of soil carbon stocks due to excavation activities that occurred during the reporting period (Ed);

 (g) emissions from fuel use to conduct the eligible project activities for the project during the reporting period (Efk).

 (7) The project proponent must use the following information for each CEA, in the units, manner and form specified by the BlueCAM Guidelines or Supplement, as input data for BlueCAM when using it to make calculations for the CEA:

 (a) the area of the CEA;

 (b) the project area as a proportion of impacted land;

 (c) land type;

 (d) for coastal wetland ecosystems covered by this determination and established following the eligible project activities for the project, the age of the vegetation in the coastal wetland ecosystems;

 (e) mean elevation relative to the relevant Australian Height Datum published by Geoscience Australia (or any of its successors);

 (f) the reporting period duration;

 (g) the permanence period for the project;

 (h) the area of the CEA where excavation activities occurred during the reporting period.
