Assessment of Deutsche Telekom's sustainability portfolio

One of the four pillars of Deutsche Telekom’s integrated climate strategy is increasing the share of more sustainable products in our product portfolio. A product can be classified as part of the company’s “sustainability-related product portfolio” if it most likely or definitely does not involve risks and offers at least one sustainability advantage. 
The assessment of the more sustainable product portfolio and associated documentation of evidence was completed in Q2020. The results showed that around 43 percent of our total revenue (2019 fiscal year, excluding USA) was generated with sustainability-related products and services.

The T-Systems product portfolio is constantly updated, as was also the case in 2019. Compared to 2018, there were several adjustments to the portfolio that were taken into account in examining the share of sustainable revenue. Following the change to the portfolio, four product portfolios were combined in two modules. This change explains the reduction in the number of product and service categories analyzed – from 29 to 27.
