AIB

Association of Issuing Bodies (AIB) publishes three types of emissions factors for 34 European countries annually:

Residual mix (Table 2 in the source file: Residual Mixes, CO2 (gCO2/kWh) column): The purpose of a Guarantee of Origin (GO) system is to enable consumers to decide how the electricity they purchase is generated by selecting a supplier and a power product. GOs provide a way to reliably track the origin of energy from production to consumption within the context of the international and complex power markets. A country’s residual mix represents the shares of electricity generation attributes available for disclosure, after the use of explicit tracking systems, such as GO, have been accounted for. Residual emission factors are used for Scope 2 reporting, market-based approach. For further information, please see the Climatiq guide on Scope 2 reporting: https://www.climatiq.io/docs/guides/understanding/selecting-electricity-efs

Total supplier mix (Table 4 in the source file: Total Supplier Mix, CO2 (gCO2/kWh) column): The total supplier mix (TSM) represents the total consumption mix of a country, i.e. it is the sum of attributes of 1) cancelled GOs as well as 2) the final residual mix. Thus, both explicitly tracked and available remaining electricity attributes are included in the TSM, which equals in physical volume with the country’s total electricity consumption. For understanding, it might help to consider that without the international transferability of GOs and electricity, the TSM would equal the production mix of the country.

Production mix (Table 5 in the source file: Production Mix, CO2 (gCO2/kWh) column): The production mix of the country is equal to the total supplier mix minus the international transferability of GOs and electricity.
