3.81  Method 1—natural gas distribution
 (1) Method 1 is
Ejp = Sp × %UAGp × 0.373 × Cjp
where:
Ejp is the fugitive emissions of gas type (j) that result from natural gas distribution through a system of pipelines with sales of gas in a State or Territory (p) during the year, measured in CO2‑e tonnes.
Sp is the total sales during the year from the pipeline system in a State or Territory (p), measured in terajoules.
%UAGp is the percentage of unaccounted for gas in the pipeline system in a State or Territory, relative to the amount of gas issued annually by gas utilities in that State or Territory.
Note: The value 0.373 following the variable %UAGp in method 1 represents the proportion of gas that is unaccounted for and released as emissions.
Cjp is the natural gas composition factor for gas type (j) for the natural gas supplied from the pipeline system in a State or Territory (p), measured in CO2‑e tonnes per terajoule.
 (2) For %UAGp in subsection (1), column 3 of an item in the following table specifies the percentage of unaccounted for gas in the pipeline system in a State or Territory specified in column 2 of that item.
 (3) For Cjp in subsection (1), columns 4 and 5 of an item in the following table specify the natural gas composition factor for carbon dioxide and methane for a pipeline system in a State or Territory specified in column 2.
