subsection (5).
 (4) For subsection (3), an ineligible Renewable Energy Certificate is:
 (a) an LGC surrendered to meet a liable entity's obligations for that compliance year under the Renewable Energy (Electricity) Act 2000; or
 (b) an incorrectly created or cancelled LGC; or
 (c) an LGC that is voluntarily surrendered and has a generation date of more than 36 months prior to the end of the reporting year.
 (5) For subsection (3), the evidence required to support the attribution of an eligible Renewable Energy Certificate to a facility's estimate of scope 2 emissions under this method is:
 (a) for a voluntarily surrendered LGC—the serial number of the LGC, as recorded on the Renewable Energy Certificate Registry;
 (b) for a purchase of GreenPower electricity from an accredited GreenPower Provider—a receipt for the purchase or a statement confirming the purchase from an accredited GreenPower Provider.
 (6) If more eligible Renewable Energy Certificates are attributed to a facility's estimate of scope 2 emissions under this method than the total required to reach zero emissions (calculated in accordance with subsection (1)), then Y is equal to zero.

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.
 (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  Required method
 (1) Uncertainty of estimates of scope 1 emissions must be assessed in accordance with Part 8.3 or with the
