\nwhere:
\nEjk<\/b> is the emissions of gas type (j), either hydrofluorocarbons or sulphur hexafluoride, summed over each equipment type (k) during a year measured in CO2 e tonnes.
\nStockjk<\/b> is the stock of gas type (j), either hydrofluorocarbons or sulphur hexafluoride, contained in equipment type (k) during a year measured in CO2 e tonnes.
\nLjk<\/b> is the default leakage rates for a year of gas type (j) mentioned in columns 3 or 4 of an item in the table in subsection (4) for the equipment type (k) mentioned in column 2 for that item.<\/p>\n
\n(b) estimates based on:<\/p>\n
\n(ii) transfers into the facility from additions of gas from purchases of new equipment and replenishments; and
\n(iii) transfers out of the facility from disposal of equipment or gas.<\/p>\n
\nwhere
\nQ = quantity of gas (with type j, as above)
\nUF = unit conversion factor (if quantity is not tonne, unit conversion factor to convert unit of capture to tonne e.g. kg to tonne = 1\/1000)
\nGWP = global warming potential for gas (with type j, as above) (t CO2-e \/ t)
\nL = default annual leakage rate for gas (with type j) in relation to equipment (with type k, as specified in the Eden Suite activity calculation configuration setting)<\/p>\n
