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 contained in foam using equations 5 to 7.Equation 5PEF = EEXTF+ ETDF
Where:
PEF = GHG emissions in the project scenario attributable to the destruction of halocarbons contained in foam, in metric tonnes CO2 equivalent;
EEXTF = Total GHG emissions attributable to the extraction of halocarbons contained in foam from appliances, calculated using Equation 6, in metric tonnes CO2 equivalent;
ETDF = GHG emissions attributable to the transportation and destruction of halocarbons contained in foam, calculated using Equation 7, in metric tonnes CO2 equivalent.
Equation 6Where:
EEXTF = Total GHG emissions attributable to the extraction of halocarbons contained in foam removed from appliances, in metric tonnes CO2 equivalent;
i = Type of halocarbon;
n = Number of types of halocarbons;
QF init,i = Initial quantity of halocarbon of type i contained in foam before their removal from appliances, calculated using Equation 4 in section 24, in metric tonnes of halocarbon of type i;
EEF = Extraction efficiency of the extraction process for halocarbons contained in foam, 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 7ETDF = QF final × 7.5
Where:
ETDF = GHG emissions attributable to the transportation and destruction of halocarbons contained in foam, in metric tonnes CO2 equivalent;
QF final = Final quantity of halocarbons contained in extracted foam and sent for destruction, calculated using Equation 17 in Appendix E, in metric tonnes of halocarbons;
7.5 = Default emission fact for the transportation and destruction of halocarbons, in metric tonnes CO2 equivalent per metric tonne of halocarbon.
