40  Historic abatement
  The historic abatement from the conversion of the methane component of coal mine waste gas from the mine, in tonnes CO2‑e, is worked out using the formula (equation 35):
where:
AH means the historic abatement from the conversion of the methane component of coal mine waste gas from the mine, in tonnes CO2‑e.
γ means the factor for converting a quantity of methane from cubic metres to tonnes CO2‑e in section 3.21 of the NGER (Measurement) Determination.
ECCMWG means the energy content factor of coal mine waste gas, in gigajoules per cubic metre, worked out in accordance with the monitoring requirements.
mean the emission factors for carbon dioxide, methane and nitrous oxide (respectively) released due to the combustion of coal mine waste gas in item 19 of Schedule 1 to the NGER (Measurement) Determination, in kilograms of CO2‑e per gigajoule.
DE means the factor for OFif in section 3.14 of the NGER (Measurement) Determination.
EH means the greater of:
 (a) the highest total emissions resulting from the combustion of the methane component of coal mine waste gas from the mine as reported in any NGER report relating to the mine covering an NGER reporting year before the application time, in tonnes CO2‑e (adjusted for any differences in CO2‑e between the NGER report and the end of the reporting period or the application time); and
 (b) the total emissions released as a result of the combustion of the methane component of coal mine waste gas from the mine, in tonnes CO2‑e (adjusted for any differences in CO2‑e between the NGER reporting year and the end of the reporting period or the application time), and determined in accordance with reporting requirements under the National Greenhouse and Energy Reporting Act 2007 in the period between:
 (i) the start of the NGER reporting year during which the application for the declaration of the project as an eligible offsets project is made; and
 (ii) the application time.
Note 1: If two or more collocated mines are part of the project, the NGER reports or calculation of emissions must include the emissions from all mines that are part of the project.
Note 2: If the result of equation 35 is greater than 5 000 tonnes CO2‑e, there has been material abatement (see section 7) and the project cannot be a new flaring or flameless oxidation project or a new electricity production project.
