8.11  Assessing uncertainty of emissions estimates for a source by aggregating parameter uncertainties
 (1) For section 8.5 and subject to subsections (2) and (3), in assessing uncertainty of the estimates of scope 1 emissions that are estimated using method 1 for a source, the aggregated uncertainty for emissions from the source is to be worked out in accordance with the following formula:

where:
D is the aggregated percentage uncertainty for the emission source.
A is the uncertainty associated with the emission factor for the source, expressed as a percentage.
B is the uncertainty associated with the energy content factor for the source, expressed as a percentage.
C is the uncertainty associated with the activity data for the source, expressed as a percentage.
 (2) If an assessment of uncertainty of emissions for the source does not require the use of emissions factor uncertainty, energy content factor uncertainty or activity data uncertainty, then A, B or C, as appropriate, in the formula in subsection (1) is taken to be zero.
Example: If energy content factor uncertainty is not required for an industrial process source, then B would be taken to be zero in the formula in subsection (1) when assessing the aggregated uncertainty for the source.
 (3) Subsection (1) does not apply to:
 (a) estimates of fugitive emissions that are assessed by using the aggregated uncertainty level in column 3 of the table in section 8.8; or
 (b) estimates of emissions from industrial processes that are assessed by using the aggregated uncertainty level in column 3 of the table in subsection 8.9(2); or
 (c) estimates of emissions from waste activities that are assessed by using the aggregated uncertainty level in column 3 of the table in section 8.10.

Part 8.4—How to assess uncertainty levels when using method 2, 3 or 4

8.14  Purpose of Part
  This Part sets out rules that apply in the assessment of uncertainty of scope 1 emissions for a source that are estimated using method 2, 3 or 4.

8.15  Rules for assessment of uncertainty using method 2, 3 or 4
 (1) Subject to this section:
 (a) the uncertainty of the following must be assessed in accordance with the uncertainty protocol:
 (i) scope 1 emissions estimates that are estimated using method 2, 3 or 4;
 (ii) scope 1 fugitive emissions estimates for open cut coal mines that are estimated using method 4; and
 (b) the uncertainty of scope 1 fugitive emissions estimates for open cut coal mines that are estimated using method 2 or 3 must be:
 (i) assessed in accordance with the uncertainty protocol; and
 (ii) estimated using the method included in section 5 of the ACARP Guidelines.
