27  Summary

      The net abatement amount for a project for a reporting period is calculated (equation 1) as:
             (1) the sum of the abatements for all sub-units of the project in the reporting period, adjusted for any negative abatements carried forward from previous years (equation 1).
      The abatement for a sub-unit is calculated (in the square brackets in equation 1) by:
             (2) taking the difference between its daily baseline emissions rate and its daily project emissions rate,
             (3) multiplying by the number of days of operation in the reporting period,
             (4) adjusting by a decay coefficient in cases where there is a reasonable probability of a decline in reliability over time of using the baseline and operating figures obtained at the beginning of the project because:
                               (a) the output is measured in the project measurement period and not in each reporting period, or
                               (b) the output in any reporting period does not satisfy the output representativeness criterion in section 23.
      Emissions factors for different types of fuel or energy are calculated by:
             (5) applying methods from the NGER (Measurement) Determination for calculating emissions from the mix of energy sources used during the baseline period and project measurement period.
      The daily baseline emission rate for a sub-unit is calculated (in equation 2) by:
             (6) measuring its output over its baseline period, using its output indicator,
             (7) measuring the energy that it uses in the baseline period,
             (8) converting the energy to emissions using the emissions factors,
             (9) converting this to a daily rate,
             (10) adjusting this rate if the rate of output during the project measurement period is lower than in the baseline period.
      The daily project emission rate for a sub-unit is calculated (in equation 4) by:
             (11) measuring its output over its project measurement period, using its output indicator,
             (12) measuring the energy that it uses in the project measurement period,
             (13) converting the energy to emissions using the emissions factors,
             (14) converting this to a daily rate.
