Second, the reported CO 2 emissions in class 1A1a do not include CO 2 emissions from autoproducers.

Gross heat production - Main Activity Producer Combined Heat and Power nrg_bal_c GHP_MAPCHP.

Gross heat production - Main Activity Producer Heat Only nrg_bal_c GHP_MAPH.

To calculate derived heat, the sum of gross heat production from public power plants (GHP_MAPH) and combined heat plants (GHP_MAPCHP) was used. This approach was used since the energy transition losses are unknown. To calculate (electrical energy + energy losses), it was assumed this equals to (electrical energy + derived heat + energy losses)–(derived heat), which in turn equals to (energy input – derived heat).

Transformation input - Main Activity Producer Heat Only nrg_bal_c GHP_MAPH.

Transformation input - Main Activity Producer Combined Heat and Power nrg_bal_c TI_EHG_MAPH.

Transformation input - Main Activity Producer Electricity Only nrg_bal_c TI_EHG_MAPE.

To calculate (electrical energy + derived heat + energy losses), which is the total output from public conventional power plants, the sum of energy input of public power plants (ESTAT:TI_EHG_MAPE_E, TI_EHG_MAPCHP and TI_EHG_MAPH) from combustion fuels (C0000X0350-0370, O4000XBIO, G3000, C0350-0370, P1000, S2000, R5110-5150, R5300, W6100_6220) was taken as approach. The ratio for calculating the share of CO 2 emissions of electricity production was calculated as (electrical energy + energy losses)/(electrical energy + derived heat + energy losses). This was done by multiplying total CO 2 emissions (1A1a), with the ratio of electricity production (plus energy losses) from public conventional thermal power stations (ESTAT:TI_EHG_MAPE_E, TI_EHG_MAPCHP, TI_EHG_MAPH and GHP were used together with ‘SIEC’ C0000X0350-0370, O4000XBIO, G3000, C0350-0370, P1000, S2000, R5110-5150, R5300, W6100_6220) versus all electrical energy production from public power stations (ESTAT: GEP_MAPE) and combined heat power station (GEP_MAPCHP). First, the CO 2 emissions of gross electricity production were calculated. As the 1A1a category shows CO 2 emissions for all energy production from Public Electricity Generation, Public Combined Heat and Power and Public Heat Plants, the following estimations were performed:

The CO 2 intensity of total electricity generation is taken as the ratio of CO 2 emissions from all electricity production, both from public main activity producers and autoproducers, against total electricity generation including electricity from nuclear plants and renewable sources. The CO 2 emissions used in this indicator (the numerator, expressed in TgCO 2) were derived from the reported total CO 2 emissions from public electricity and heat generation from the EEA greenhouse gas data viewer (code: 1A1a).
