IGES List of Grid Emission Factors | IGES Publication Database

A "grid emission factor" refers to a CO2 emission factor (tCO2/MWh) which will be associated with each unit of electricity provided by an electricity system. It is a parameter to determine the baseline emissions for CDM projects in the renewable energy sector (hydro, wind, solar PV, and geothermal power, etc.) and waste heat/gas recovery sector.

However, it is preferred if you have data from a site-specific stack test to develop an emission factor for the source. HAPs: Usually you will have either SDS information or an AP-42 emission factor available to determine the HAP emissions. Sometimes only trade associations have emissions data and make it available only to members.

Emission intensity - Wikipedia

In general, the use of country-specific emission factors would provide more accurate estimates of emissions than the use of the default emission factors. According to the IPCC, if an activity is a major source of emissions for a country ('key source'), it is 'good practice' to develop a country-specific emission factor for that activity.
