Part 1—Preliminary 1 Name This is the Carbon Credits (Carbon Farming Initiative—Savanna Fire and Emissions Avoidance) Methodology Determination 2018. 2 Commencement This determination commences on the day after it is registered. 3 Authority This determination is made under subsection 106(1) of the Carbon Credits (Carbon Farming Initiative) Act 2011. 4 Duration This determination remains in force for the period that: (a) begins when this instrument commences; and (b) ends on the day before this instrument would otherwise be repealed under subsection 50(1) of the Legislation Act 2003. 5 Definitions In this determination: Act the Carbon Credits (Carbon Farming Initiative) Act 2011. baseline period, for a project area or a part of a project area—see section 8 and (for land within a transferring project area) section 26. calendar year a period of 12 months starting on 1 January. CFI Rule means the Carbon Credits (Carbon Farming Initiative) Rule 2015. CO2-e means carbon dioxide equivalent. continuing transferring project—see section 24. early dry season—see section 7. fire season—see section 7. former determination, for a transferring project area—see section 24. fuel size class means the following: (a) shrub fuel; (b) fine fuel; (c) coarse fuel; (d) fuel. GIS means geographic information system.
FRIv is the mean fire return interval for vegetation of vegetation fuel type v for the project area and for the relevant calculation period, as calculated using equation 9, in years. BEf,s is the burning efficiency for fuel of fuel size class f in fire season s, from the National Inventory Report. FFv,s is the average fire frequency in vegetation of vegetation fuel type v in fire season s for the project area and for the relevant calculation period, in from equation 8. Ps is the patchiness for fire season s, from the National Inventory Report. (6) For paragraph (2)(d), the equation is the following: equation 11 where: Lf,v is the annual rate of accumulation of fuel of fuel size class f that is of vegetation fuel type v, as given by the National Inventory Report, in tonnes of biomass per hectare per year. Df,v is the amount of vegetation of fuel of fuel size class f that is of vegetation fuel type v that decomposes each year in a given area, as given by the National Inventory Report, in years–1. is the mean proportion of fuel of fuel size class f that is of vegetation fuel type v that remains after a fire for the project area and for the relevant calculation period, as calculated using equation 10. FRIv is the mean fire return interval for vegetation of vegetation fuel type v for the project area and for the relevant calculation period, as calculated using equation 9, in years. (7) For paragraph (2)(e), the equation is the following: equation 12 is the amount for the project area calculated in accordance with equation 11 over the baseline period (paragraph (a) of the definition of relevant calculation period in section 5), in tonnes of biomass per hectare. is the amount for the project area calculated in accordance with equation 11 over the relevant calculation period (paragraph (b) of the definition of that term in section 5), in tonnes of biomass per hectare. LEA, for a particular calendar year, is equal to: (a) for a year of the baseline period—zero; and
(2) For that calendar year, is taken to be equal to . 12 Adjustments resulting from subdivided project If a project area is divided into 2 or more subdivided project areas, then BU,Prev for each subdivided project area immediately after the subdivision takes effect is equal to the amount BU,Prev,Subdiv given by the following equation: equation 13 where: is the average annual baseline fire emissions for the subdivided project area, , in tonnes CO2-e, as calculated in accordance with section 6 of this Schedule for the subdivided project area. is the average annual baseline fire emissions for the original project area, , in tonnes CO2-e, as calculated in accordance with section 6 of this Schedule, for the original project area. BU,Prev,Orig is the previous year’s uncertainty buffer for the original project area, BU,Prev, as given by subsection 3(1) of this Schedule as if the project area had not been divided.
