25. For the purposes of the quantification of the GHG emission reductions attributable to the project, the promoter must calculate the GHG emissions in the project scenario attributable to the destruction of halocarbons using equations 5 to 7.Equation 5
PE = EEXT + ETD
Where:
PE = GHG emissions in the project scenario attributable to the destruction of halocarbons, in metric tonnes CO2 equivalent;
EEXT = Total GHG emissions attributable to the extraction of halocarbons, calculated using Equation 6, in metric tonnes CO2 equivalent;
ETD = GHG emissions attributable to the transportation and destruction of halocarbons, calculated using Equation 7, in metric tonnes CO2 equivalent.
Equation 6
Where:
EEXT = Total GHG emissions attributable to the extraction of halocarbons, in metric tonnes CO2 equivalent;
i = Type of halocarbon;
n = Number of types of halocarbons;
Q init, i = Initial quantity of halocarbon of type i contained in foam prior to removal from appliances, calculated using Equation 4 in section 24, in metric tonnes of halocarbon of type i;
EE = Extraction efficiency of the extraction process for halocarbons, determined in accordance with the method in Appendix E;
GWPi = Global warming potential factor for halocarbon of type i as indicated in section 22, in metric tonnes CO2 equivalent per metric tonne of halocarbon of type i;
Equation 7
ÉTD = Q final × 7.5
Where:
ETD = GHG emissions attributable to the transportation and destruction of halocarbons, in metric tonnes CO2 equivalent;
Q final = Final quantity of halocarbon extracted and sent for destruction, calculated using Equation 17 in Appendix E, in metric tonnes of halocarbon;
7.5 = Default emission factor for the transportation and destruction of halocarbons, in metric tonnes CO2 equivalent per metric tonne of halocarbon.
