| Methodology description | A grid emission factor is a CO₂ emission factor (tCO₂/MWh) associated with each unit of electricity provided by an electricity system. It is used to determine baseline emissions for Clean Development Mechanism (CDM) projects in the renewable energy sector (hydro, wind, solar PV, geothermal, etc.) and the waste heat/gas recovery sector. The IGES Grid Emission Factor Database provides two types of grid emission factor: CDM-based grid emission factors, calculated and used by individual registered CDM projects. Data is extracted from the UNFCCC website and provided in the IGES CDM Project Database. For further information on individual project activities, refer to the CDM Project Database. Official grid emission factors, published either by host country governments or as CDM standardised baselines approved by the CDM Executive Board. Factors from host country governments are taken from publicly available sources; CDM standardised baselines are taken from the CDM website. Climatiq has extracted Operating Margin (OM) and Build Margin (BM) data from the "EFfromCountriesOrSB" sheet, which contains official grid emission factors from host country governments ("National publication") and CDM standardised baselines ("CDM SB"): OM (Operating Margin) is the emission factor representing the group of existing power plants whose current electricity generation would be affected by the proposed CDM project activity. BM (Build Margin) is the emission factor representing the group of prospective power plants whose construction and future operation would be affected by the proposed CDM project activity.
