Analysis of selected sustainability-related products

Products that take environmental or social aspects into account at different stages of their life cycle are of strategic importance to Deutsche Telekom. However, there is still no industry-wide standard that provides comparable sustainability information on ICT products and services. We therefore consider corresponding aspects with the help of our own analysis method. Among other things, this examines aspects of product safety and recyclability. In this way, we want to create transparency at the portfolio level and supplement our impact measurement with a sales-related view.

Measuring progress 2025: analysis of selected products

We use the KPI “Share of revenue with sustainability relevance” to determine how much revenue we generate (excluding T‑Mobile US) from products that, based on our analysis, have no or low probability of environmental or social risks and can make a potential positive environmental or social contribution.

In the reporting year, the share was 43 %, as in the previous year. For the calculation of the KPI “Share of revenue with sustainability relevance”, a total of 37 products and solutions were examined in detail in 2025 (2024: 37).

The products and solutions examined are divided into four product clusters:

• Broadband (fixed)/wholesale: Revenues from fixed-line broadband services as well as from wholesale and wholesale business for residential and business customers.

• T‑Systems Services & Solutions: Revenues from infrastructure and cloud services as well as from selected industry-specific solutions for business customers.

• Mobile Broadband (data only): Revenues from mobile data services without voice components for private and business customers.

• Leased devices: Revenues from the rental of mobile and fixed-line terminals, as they are also taken into account in the context of the EU taxonomy.

The following criteria apply to the calculation of the KPI: A product can only be considered if, according to our analysis, it has a very low probability of having one of the seven risks defined by us in the production and application phase.

These risks include: pollution in the manufacture of ICT products; avoidable, non-recyclable e-waste; ethically unacceptable working conditions; use of conflict minerals in the production phase; social exclusion; radiation and health effects; Information security.

In addition, a product is only considered if at least one of five environmental or social characteristics can be assigned to it on the basis of our analysis: reduced energy consumption in the production and/or application phase; a potential reduction in CO₂ emissions; approaches to the circular economy; a reduction in the amount of time spent; as well as the support of social participation.

Economic aspects, such as cost savings, have no influence on the allocation of products in the context of the KPI survey.

In line with the logic of the EU taxonomy, we have also included revenue from the rental of terminal equipment in the fixed-network sector since 2023. These account for about two percent of the total value. In the case of mobile broadband revenues, data and voice revenues can only be separated to a limited extent. The crediting is therefore based on assumptions. The background to this consideration is that the EU Taxonomy Regulation still did not reflect significant parts of our service-based business model in the reporting year.
