Chapter 8    Assessment of uncertainty

Part 8.1              Preliminary

  

8.1           Outline of Chapter

         (1)   This Chapter sets out rules about how uncertainty is to be assessed in working out estimates of scope 1 emissions for a source, a facility and a registered corporation.

         (2)   Part 8.2 sets out general rules for assessing uncertainty of scope 1 emissions estimates.

         (3)   Part 8.3 sets out how to assess the uncertainty of estimates of scope 1 emissions that have been estimated using method 1.

         (4)   Part 8.4 sets out how to assess the uncertainty of estimates of scope 1 emissions that have been estimated using method 2, 3 or 4.

         (5)   Emissions estimates for a source that are calculated using method 1, 2 or 3 are a function of a number of parameters. The uncertainty of the emissions estimates consists of the uncertainty associated with each of these parameters, which may include one or more of the following parameters:

                (a)    energy content factor;

               (b)    emissions factor;

                (c)    activity data.

Note   In the case of fuel combustion, activity data refers to the quantity of fuel combusted. In the case of industrial processes, activity data refers to the quantity of product consumed or produced, as appropriate.

         (6)   Estimates of emissions need only provide for statistical uncertainty.

Note   The uncertainty protocol provides information about the assessment of uncertainty.

Part 8.2              General rules for assessing uncertainty

  

8.2           Range for emission estimates

                Uncertainty must be assessed so that the range for an emissions estimate encompasses the actual amount of the emissions with 95% confidence.

8.3           Uncertainty to be assessed having regard to all facilities

         (1)   Uncertainty of estimates of scope 1 emissions for a registered corporation must be assessed in accordance with Part 8.3 or with the uncertainty protocol, as appropriate, having regard to all of the facilities under the operational control of the corporation.

         (2)   For corporations that have multiple sources of scope 1 emissions that are estimated using a variety of method 1, 2, 3 or 4, the uncertainty associated with the emissions must be aggregated in accordance with section 8 of the uncertainty protocol.

Part 8.3              How to assess uncertainty when using method 1

  

8.4           Purpose of Part

                This Part sets out how to assess uncertainty of scope 1 emissions if method 1 is used to estimate:

                (a)    scope 1 emissions for a source; and

               (b)    scope 1 emissions for a facility; and

                (c)    scope 1 emissions for a registered corporation.

8.5           General rules about uncertainty estimates for emissions estimates using method 1

         (1)   The total uncertainty of scope 1 emissions estimates for a source in relation to a registered corporation is to be worked out by aggregating, as applicable, the uncertainty of the emissions factor, the energy content factor and the activity data for the source in accordance with the formula in section 8.11.

Note   This is generally referred to as the aggregated uncertainty for the source.

         (2)   The total uncertainty of scope 1 emissions estimates for a facility is to be worked out by aggregating the total uncertainty for each source associated with the facility in accordance with the formula in section 8.12.

Note   This is generally referred to as the subtotal uncertainty for the facility.

         (3)   The total uncertainty of scope 1 emissions estimates for a registered corporation is to be worked out by aggregating the total uncertainty for each facility under the operational control of the corporation in accordance with the formula in section 8.13.

Note   This is generally referred to as the total uncertainty for the corporation.

8.6           Assessment of uncertainty for estimates of carbon dioxide emissions from combustion of fuels

         (1)   In assessing uncertainty of the estimates of carbon dioxide emissions estimated using method 1 for a source that involves the combustion of a fuel, the assessment must include the statistical uncertainty associated with the following parameters:

                (a)    the energy content factor of the fuel (as specified in column 3 of the following table or as worked out in accordance with item 1, 2 or 3 of section 7 of the uncertainty protocol);

               (b)    the carbon dioxide emission factor of the fuel (as specified in column 4 of the following table or as worked out in accordance with item 1, 2 or 3 of section 7 of the uncertainty protocol);

                (c)    the quantity of fuel combusted (as worked out in accordance with subsection (2) or as worked out in accordance with item 1, 2 or 3 of section 7 of the uncertainty protocol).

8.11        Assessing uncertainty of emissions estimates for a source by aggregating parameter uncertainties

         (1)   For subsection 8.5 (1) 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

8.12        Assessing uncertainty of emissions estimates for a facility

                For subsection 8.5 (2), in assessing uncertainty of estimates of scope 1 emissions for a facility that are estimated using method 1, the following formula must be used to aggregate the uncertainty of emissions estimates for all the sources associated with the facility:

where:

Usubtotal is the percentage uncertainty for the subtotal of emissions for the facility.

D1 → Dn are the percentage uncertainties associated with each emission estimate (E1 → En) for the facility.

E1 → En are the estimated emissions from each facility under the operational control of the corporation measured in CO2-e tonnes.

8.13        Assessing uncertainty of emissions estimates for a registered corporation

                For subsection 8.5 (3), in assessing uncertainty of estimates of scope 1 emissions for a registered corporation that are estimated using method 1, the following formula must be used to aggregate the uncertainty of emissions estimates for all the facilities under the operational control of the corporation:

where:

Utotal is the percentage uncertainty for the total emissions for the registered corporation.

D1 → Dn are the percentage uncertainties associated with each emission estimate (E1 → En) for the facility.

E1 → En are the estimated emissions from each facility under the operational control of the corporation measured in CO2-e tonnes.

Example

A landfill in a State is licensed only to receive commercial and industrial waste. A condition of the licence is that the landfill is restricted to receiving no more than 5% (Wmtrmax = 5%) food waste in its deliveries. The landfill operator accounts for this restriction by using the formula for each unrestricted waste type (Wmtu) in the table above. So, for paper and paper board waste, the calculation is:

The operator would continue to use the formula for each unrestricted waste mix type. For the restricted waste mix type the percentage used is Wmtrmax.
