Indicator Specification
Greenhouse gas emission intensity of electricity generation in Europe
Go to latest version
Rationale
Justification for indicator selection
The EU aims to be climate-neutral (i.e. its economy will emit net-zero greenhouse gas emissions) by 2050. This objective is at the heart of the European Green Deal and in line with the EU's commitment to global climate action under the Paris Agreement. Decarbonising electricity supply, for instance by substantially accelerating the deployment of renewable energy sources to achieve a share of almost 70% in generation by 2030 and above 80% by 2050, is critical to achieving this objective.

Indicator definition

Methodology
Methodology for indicator calculation
The GHG intensity of total electricity generation is taken as the ratio of CO2 equivalent emissions from all electricity production (both from main activity producers and auto-producers) to total electricity generation, including electricity from nuclear plants and renewable sources.
For main activity producers, the CO2e emissions from electricity generation only (i.e. excluding emissions resulting from heat production), were estimated as follows:
a) Estimating the transformation input for gross heat production by multiplying gross heat production (ESTAT codes GHP_MAPCHP and GHP_MAPH) by 90% (the assumed efficiency for heat production);
b) Estimating the transformation input for electricity generation by subtracting the estimated transformation input for gross heat production from total transformation input for electricity and heat generation (ESTAT codes TI_EHG_MAPE_E, TI_EHG_MAPCHP_E, and TI_EHG_MAPH_E);
c) Multiplying the ratio of b) and the transformation input for electricity and heat generation (ESTAT codes TI_EHG_MAPE_E, TI_EHG_MAPCHP_E, and TI_EHG_MAPH_E) to total CO2e emissions from public electricity and heat production (1A1a from the EEA data viewer).
The reported CO2e emissions in class 1A1a do not include CO2e emissions from autoproducers. Emissions from electricity generated by autoproducers were estimated by multiplying the ratio of the energy input for autoproducers and the energy input for main activity producers by the CO2e emissions from main activity producers (as calculated in steps a-c above). The energy input for electricity generation by autoproducers was estimated using the same method as for main activity producers (a and b above) using the ESTAT codes GHP_APH and GHP_APCHP for gross heat production and TI_EHG_APE_E, TI_EHG_APCHP_E, and TI_EHG_APH_E for transformation input for electricity and heat production.
A zero CO2e emission factor was applied to nuclear power and to renewables (including the biodegradable fraction of municipal solid waste), as the method does not take into account life-cycle greenhouse gas emissions. This applies also to solid biofuels: in accordance with the United Framework Convention on Climate Change Reporting Guidelines, biofuel-related emissions have to be reported as a memorandum item in greenhouse gas emission inventories, with the assumption being that harvesting emissions would be shown as changes in carbon stocks in the land use, land use change and forestry sector, not in the energy sector. This should not be interpreted, however, as an endorsement of default carbon neutrality or the sustainability of biofuels.
The denominator of the GHG intensity of total electricity production is the sum of electricity produced from main activity producers (ESTAT: GEP_MAPE and GEP_MAPCHP) and autoproducers (ESTAT: GEP_APE and GEP_APCHP).
Calculation Formula: (CO2e * ((ei_MAP – dh_MAP/0.9) / ei_MAP)) * ((ei_AP - dh_AP/0.9) / (ei_MAP - dh_MAP / 0.9)) + CO2e * ((ei_MAP – dh_MAP/0.9) / ei_MAP))) / (GEP / 85.98), where:
- CO2e represents ‘CO2 equivalent emissions - Fuel combustion in public electricity and heat production (A1A1)’, from the EEA greenhouse gas data viewer. The values do not include CO2e emissions from the combustion of biomass; nor do they include upstream emissions (e.g. fugitive emissions due to methane leaks or construction emissions);
- ‘ei_MAP’ represents ‘energy input of Main Activity Producers’ and includes ‘TI_EHG_MAPE_E’, ‘TI_EHG_MAPCHP_E’ and ‘TI_EHG_MAPH_E’;
- ‘ei_AP’ represents ‘energy input of Autoproducers’ and includes ‘TI_EHG_APE’, ‘TI_EHG_APCHP_E’ and ‘TI_EHG_APH_E’;
- ‘dh_MAP’ represents ‘derived heat of Main Activity Producers’ and includes ‘GHP_MAPCHP’ and ‘GHP_MAPH’;
- ‘dh_AP’ represents ‘derived heat of Autoproducers’ and includes ‘GHP_APCHP’ and ‘CHP _APH’;
- ‘GEP’ represents ‘Gross electricity production’ and includes ‘GEP_MAPE’, ‘GEP_MAPCHP’, ‘GEP_APE’ and ‘GEP_APECHP’;
- 0.9 represents the assumed efficiency of heat production. A pro-rata split of CO2 between heat and electricity is assumed;
- 85.98 represents the conversion factor from kilotonnes oil equivalent to GWh.
