Ex-ante Monitoring: Monitoring Ex-ante: Prior to the project validation, the following parameters must be collected for ex-ante emission reductions calculation. The following plant emission factors used for the calculation of the OM and BM emission factors should be obtained on the basis of the ranking of data sources given in ACM0002 (version 06): • Data required to recalculate the BM emission factor (if option 1 is chosen for the baseline emission factor calculation); • Data required to recalculate the OM emission factor (if option 2 is chosen for the baseline emission factor calculation); • CO 2 emission coefficient of fuels used by the identified baseline scenario by fuel type (if option 3 is chosen for the baseline emission factor calculation); • Energy efficiency of the technology used in the identified baseline scenario (if option 3 is chosen for the baseline emission factor calculation); and Gas Availability • Availability of natural gas in the project region. Ex-post monitoring Ex-post: After the project implementation, monitoring shall be conducted on the following items: • Data required to recalculate the OM emission factor (if ex-post calculation is chosen); • Data required to recalculate the BM emission factor (if ex-post calculation is chosen); • Power generation of the project; • Fuel consumption of the project by fuel type; • CO 2 emission coefficient of fuels used by the project by fuel type; • Emission factor for upstream fugitive CH 4 emissions of natural gas combusted by the project; • Emission factor for upstream fugitive CH 4 emissions occurring in the identified baseline scenario; and • Emission factor for upstream CO 2 emissions due to fossil fuel combustion/ power consumption associated with the liquefaction, transportation, regasification and compression into a natural gas transmission or distribution system (only if the project uses LNG). 62
Industrial Gas Methodologies 5.3 Decomposition of industrial gases HFC-23 and N 2 O 5.3.1 Methodologies analyzed Large Scale Large Scale Large Scale AM0001 (version 5) “Incineration of HFC waste streams” AM0021 (version 1) “Baseline methodology for decomposition of N2O emissions from existing adipic acid production plants” AM0034 (version 2) “Catalytic reduction of N2O inside the burner of nitric acid plants” 5.3.2 Basic concept Chemical Production releases strong Greenhouse Gases Emissions Reduction through thermal Decomposition All three methodologies deal with the “end-of-pipe” decomposition of industrial gases HFC-23 (Fluoroform) or N 2 O (Nitrous oxide). The gases are un-wanted by-products from production plants of the chemical industry and have a very high Global Warming Potential (1t N 2 O = 310 t CO 2 eq. and HFC- 23 = 11,700 t CO 2 eq.). This makes decomposition of such gases the most attractive CDM projects in the market with costs of CER generation ranging from 0.1 – 0.5 €/CER. All three methodologies assume that in the absence of the CDM project, HFC-23/ N 2 O emissions would have been released to the atmosphere via the stack of the plant. Therefore, the common and most important rationale of the methodologies is that emission reductions are the difference between the emissions of the gas from the plant before (baseline emissions) and after implementation of the decomposition facility (project emissions) and adjusted for potential indirect emissions due to the project. ER y = EF bl,y X Prod bl,y X GWP - PE y - Leakage Emission Reductions Basel Emission factor of baseline Baseline amount of industrial gas production Global warming potential of industrial gas Direct emissions of the project (e.g. fuel combustion or industrial gas still released) Indirect emissions due to the project Methodologies only applicable for existing Capacity Baseline emissions (expressed in HFC-23 or N 2 O) are determined by multiplying a historic emission factor (t HFC-23 or t N 2 O/ per t of HCFC-22 or adipic acid or nitric acid produced) with the amount of production of the chemical product after installation of the destruction facility. The plant output eligible for calculation of baseline emissions is capped at historic production levels to ensure the environmental integrity of such CDM projects. For the same reason, greenfield chemical production plants are not allowed to use the approved methodologies (see Box 21). 63
