Assessment of Deutsche Telekom’s sustainability portfolio

Deutsche Telekom’s integrated climate strategy comprises four pillars, or main areas. One of the pillars consists of actions aimed at increasing the share of sustainable products and services in our product portfolio. A product can be classified as part of the company’s “sustainable product portfolio” if it most likely, or definitely, does not involve risks, and if it offers at least one sustainability advantage.

The assessment of our sustainable-product portfolio, including the relevant verifying documentation, was completed in Q2023. The results showed that 42 percent of our total revenue (2022 fiscal year, excluding USA) was generated with sustainability-related products and services. In the year under review, our analysis also included review of selected products in light of EU taxonomy img criteria.

The T-Systems product portfolio is constantly updated, as was also the case in 2022. Compared to 2020 there were several adjustments to the portfolio that were taken into account in examining the share of sustained revenue. As a result of these portfolio adjustments, the number of reviewed product/service categories increased from 33 to 35 overall.

Adjustments were also made to the assessment methods. Now, intensified use of renewable energies (benefit 2) no longer counts as a benefit that would lead to the relevant portfolio element’s being assessed as “sustainable.” This change reflects the fact that the entire Group is now using renewable energies. As in previous years, potential cost savings (benefit 7) function only as additional information; they do not automatically lead to assessment as “sustainable.”
