ESG Reporting 2025

Key indicators 2023–2025

We measure our ESG performance using key performance indicators (KPIs) in accordance with the European Sustainability Reporting Standards (ESRS). The KPIs apply to the Telefónica Deutschland Group and refer to the fiscal years 2023, 2024, and 2025. The KPIs marked with a symbol have been audited with limited assurance by an auditing firm. The full audit note can be viewed under Downloads.

The values in the key figure table are rounded up or down. Due to this rounding, it is possible that in some rows of the tables the rounded figures do not add up exactly to the specified total. For the 2023 reporting year, the key figures were collected in accordance with the GRI/GHG Protocol and not yet in accordance with CSRD/ESRS. These values have not been adjusted backwards.

Telefónica Deutschland Group sources its electricity via the electricity market. The acquired electricity mix is qualified as 100% electricity from renewable energy sources using Guarantee of Origin certificates. There are also sites already powered by self-generated solar electricity. The remaining emissions mainly relate to fleet consumption, backup power generators and district heating or natural gas purchases.

2

A similar level of reduction is expected in the future.

3

Since most of the base stations with active air conditioning systems had already been converted to free cooling systems in the previous year, the conversion measures and the resulting energy efficiency gains were lower in 2025.

Fuel consumption (in the form of diesel, natural gas and district heating) includes units supplied directly to Telefónica Deutschland Group facilities under direct contracts with energy providers. The consumption is derived from the actual billed and partially forecasted quantities per delivery point. The calculation of fuel consumption is conducted in accordance with Telefónica, S.A., using international conversion factors and verified by the Spanish standards and certification body AENOR INTERNACIONAL, S.A.U.

2

Consumption from purchased or acquired electricity, heat, steam or cooling from fossil sources only includes district heating in Telefónica Deutschland Group.

In 2025, Telefónica updated its Scope 3 calculation methodology following a Group wide screening in line with the GHG Protocol and SBTi. Key changes include: (i) expanded accounting of purchased goods and services (Categories 1 and 2), including full supplier emissions and purchases outside the Procurement Model; (ii) inclusion of transmission and distribution losses for renewable electricity (Category 3); (iii) addition of Well to Tank emissions and employee assigned vehicles (Category 6); (iv) reclassification of leased customer routers from Category 11 to Category 13; and (v) expanded accounting of leased equipment and third party electricity use within Telefónica’s infrastructure (Category 13). As the updates change total Scope 3 emissions by more than 5%, both the 2016 base year and 2024 have been recalculated. All recalculated 2024 category values are also provided and audited in the AENOR certificate.

2

The increase in purchased goods and services was due to methodological adjustments, but also to an increase in the volume of purchases from suppliers not included in the procurement model, typically small and medium-sized enterprises.

3

Emissions from business travel were significantly reduced compared to the previous year through a consistent reduction in business trips and the use of low-carbon modes of travel.

4

In terms of the use of products sold, emissions were reduced due to an increase in sales of lower-emission devices such as smartphones and computers and lower sales of high-emission devices such as TVs and video game consoles.

Due to increased reuse of network components in the course of 5G expansion and network modernization, as well as a methodological switch to detailed service provider reporting for office equipment, the reuse rate has increased compared to the previous year.

2

Other recovery actions include e.g. thermal recovery and chemical/physical/biological recovery.

3

The total amount of waste generated in 2024 also included the amount of reused equipment. Using the new methodology, non-hazardous waste would have amounted to 1,416 tons, and the total amount of waste generated would have been 1,510 tons. From 2025 onwards, reused products were reported separately from waste.

Due to a methodological adjustment, working students are no longer reported as non-guaranteed hourly workers but as temporary workers; contracts with longer terms of more than six months are considered permanent positions. According to the new methodology, there would have been 7,671 permanent employees, 210 employees with fixed-term contracts and 0 non-guaranteed hourly workers for the year 2024.

5

All Telefónica Germany employees are either permanent or temporary employees; Telefónica Germany does not employ any non-guaranteed hourly workers. In 2024, working students were classified both as temporary employees and as non-guaranteed hourly workers. This classification has been corrected for 2025, and all working students are now consistently classified as temporary employees. From 2025 onwards, employees with longer-term contracts (exceeding six months) are classified as permanent employees.

The figures here and in the report comprise the volume and number of orders placed by the Telefónica Deutschland Group that are processed via Telefónica Global Services GmbH (TGS) (MCT suppliers). The figures include all the orders up to 31 December of the financial year in question, irrespective of their processing date. All the latest ACM (ACM is a purchasing tool used to manage the purchasing processes) data is taken into account.

Concerns all the suppliers who were contracted in 2025.

3

As contractual partners, all new suppliers are obliged to accept the Supply Chain Sustainability Policy.

4

The increase results from a lower number of identified potential high‑risk suppliers due to the revised group‑wide methodology, which now relies exclusively on an inside‑out ESG analysis and no longer incorporates financial or reputational risk considerations.

In 2025, Telefónica updated its Scope 3 calculation methodology following a Group wide screening in line with the GHG Protocol and SBTi. Key changes include: (i) expanded accounting of purchased goods and services (Categories 1 and 2), including full supplier emissions and purchases outside the Procurement Model; (ii) inclusion of transmission and distribution losses for renewable electricity (Category 3); (iii) addition of Well to Tank emissions and employee assigned vehicles (Category 6); (iv) reclassification of leased customer routers from Category 11 to Category 13; and (v) expanded accounting of leased equipment and third party electricity use within Telefónica’s infrastructure (Category 13). As the updates change total Scope 3 emissions by more than 5%, both the 2016 base year and 2024 have been recalculated. All recalculated 2024 category values are also provided and audited in the AENOR certificate.

The selected population-based evaluation also includes commuter flows within the population, with the result that part of the population is counted both in their residences and in their workplaces (maximum population). In doing this, Telefónica Deutschland Group takes into account that demand for communication services arises both at home and on the move. This value indicates availability of mobile services outside buildings (outdoors). Rural population is defined according to Bundesinstitut für Bau-, Stadt- und Raumforschung (BBSR – Federal Institute for Research on Building, Urban Affairs and Spatial Development) within Bundesamt für Bauwesen und Raumordnung (BBR – Federal Office for Building and Regional Planning) and comprises all districts classified as “Dünn besiedelter ländlicher Kreis” (sparsely populated rural district) or “Ländlicher Kreis mit Verdichtungsansätzen” (Rural district with densification approaches).
