Overview of Repower Group employees in full-time equivalents (FTEs)

Greenhouse gas emissions

The calculation of greenhouse gas emissions is based on the Greenhouse Gas (GHG) Protocol and the operational control approach. The base year is 2022; 2022 was chosen as the base year because that was the year greenhouse gas emissions for Scopes 1, 2 and 3 were systematically recorded for the first time.

Explanations of greenhouse gas emissions

Direct greenhouse gas emissions (Scope 1)

Scope 1 covers all direct greenhouse gas emissions (excluding biogenic emissions) of the Repower Group. These include emissions from stationary combustion sources and fuel consumption of vehicles, which are calculated based on the fuel used. Fugitive emissions comprise SF6 and refrigerants. These are calculated on the basis of weight. Direct emissions from electricity generation depend on the volume of electricity generated and are calculated on an activity basis. Direct emissions from natural gas combustion in Italian plants such as Teverola combined-cycle gas turbine power plant are modelled using the plant’s ETS data combined with national standard coefficients (M.A.S.E) and DEFRA conversion factors to increase accuracy. The T&D components are considered separately using the DEFRA conversion factors and the results of Repower’s ISO 14067 study. Biogenic emissions are not included because only very small amounts are involved.

Energy indirect greenhouse gas emissions (Scope 2)

Scope 2 covers the indirect emissions stemming from the Repower Group’s use of electricity and the transmission losses in its own power grid. The emissions are calculated on both a market basis and a location basis. The market-based figures are relevant for the climate targets. Emissions at Repower Switzerland are calculated on both a market basis in accordance with electricity labelling and on a location basis in accordance with the generation mix. Repower Switzerland uses the previous year’s electricity labelling for the calculation. Repower Italia uses the Association of Issuing Bodies (AIB) factors both for the market approach (residual mix) and for the location approach (generation mix).

Other indirect greenhouse gas emissions (Scope 3)

Scope 3 emissions relate to upstream and downstream activities along the value chain (excluding biogenic emissions). These are divided into 15 subcategories according to the GHG Protocol. Repower Switzerland and Repower Italy did a separate materiality analysis in which the relevant subcategories were defined. Given their low share of total emissions, subcategories 3.4, 3.8, 3.9, 3.10, 3.12, 3.13 and 3.14 were not considered relevant for the Repower Group. Subcategories 3.6 and 3.15 are only calculated for Repower Switzerland; for Repower Italia, these subcategories were not considered relevant given to their low share of Repower Italia’s total emissions. Biogenic emissions are not included because only very small amounts are involved.

3.1 Purchased goods and services: Repower does a low-accuracy, spend-based calculation. For 2022 and 2023, at Repower Switzerland only purchased goods and services at Repower AG were included. From 2024, data from all Repower companies have been included. The data for 2023 and 2022 have not been adjusted, because the change accounts for less than 0.1 per cent of subcategory 3.1 and is therefore negligible. Repower Italia also includes in subcategory 3.1 the upstream emissions of the gas it sells, applying an activity-based approach.

3.2 Capital goods: Repower does a low-accuracy, spend-based calculation. For 2022 and 2023, at Repower Switzerland only capital goods at Repower AG were included. From 2024, data from all Repower companies have been included. The data for 2023 and 2022 have not been adjusted, because the change accounts for less than 1 per cent of subcategory 3.2 and is therefore negligible.

3.3 Fuel and energy-related activities: Subcategory 3.3 includes, firstly, the upstream emissions of purchased fuels, which are calculated on a fuel basis; secondly, the upstream emissions of purchased electricity; and thirdly, the emissions of purchased electricity for end-consumers, which are calculated on a market basis. Repower Switzerland uses the previous year’s electricity labelling for each of these. Repower Italia uses the previous year’s AIB factors for the calculation. For 2022 and 2023, the upstream emissions from electricity generation at Repower Switzerland were also conservatively counted in subcategory 3.3. Since this led to double counting, from 2024 the upstream emissions from electricity generation have only been included in subcategory 3.1 or 3.2.

3.5 Waste: Emissions from waste are calculated on a weight basis. If no information on waste is available, Repower Italia uses average Italian recovery factors from the “Il riciclo in Italia” report.

3.6 Business travel: Repower Switzerland calculates the emissions stemming from business trips based on expenditure at a low level of accuracy. For 2022 and 2023, only business travel at Repower AG was included. From 2024, data from all Repower companies in Switzerland and Germany have been included. The data for 2023 and 2022 were not adjusted, because the change accounts for less than 1 per cent of subcategory 3.6 and is therefore negligible. Repower Italia does not take subcategory 3.6 into account because its share of total emissions is very low.

3.7 Employee commuting: Repower Switzerland calculates emissions using country-specific average data. Repower Italia uses data from an internal study of commuting habits among employees of the Milan office. The emissions for the employees of the Teverola gas-fired combined cycle power plant are estimated by applying an average factor.

3.11 Use of products sold: The subcategory primarily includes emissions from natural gas sold to and combusted by customers in Italy. The emissions are calculated on a location basis using the same methodology and sources and include in particular the gas sold and consumed in Italy as explained in Scope 1.

3.15 Investments: Repower Switzerland does an activity-based calculation. For power generation assets without operational control, only Repower’s interests are taken into account. Nuclear power plant purchase rights are not included, as Repower has no interest in them. Repower Italia does not include subcategory 3.15 as it has no generation assets without operational control.

Other: For the 2022 and 2023 reporting years, Repower Switzerland calculated the emissions for categories 3.4 (upstream transport and distribution), 3.8 (rented and leased tangible assets) and 3.12 (end-of-life treatment of sold products); these are summarised in the category Other. These subcategories are no longer be calculated for the 2024 reporting year because they are currently not considered relevant.
