CR reporting has been common practice at Deutsche Telekom for over 25 years. In addition to our CR report, we have been publishing a non-financial statement in our Annual Report annually since the 2017 reporting year, thus meeting the requirements of Sections 289c to 289e of the German Commercial Code (HGB), Sections 315c in conjunction with 289c to 289e of the German Commercial Code (HGB) and the EU Taxonomy Regulation. In the reporting year, we prepared the non-financial statement for the second time in a row as a Sustainability statement in full application of the European Sustainability Reporting Standards (ESRS).
In 2024, for the first time, we conducted a double materiality analysis in accordance with the requirements of the Corporate Sustainability Reporting Directive (CSRD) to identify impacts on society and the environment as well as risks and opportunities for our business activities in connection with sustainability issues. In the reporting year, we updated this materiality analysis. Further information on the materiality process and its results can be found in our Sustainability statement.
In addition to the material impacts, risks and opportunities addressed in the Sustainability statement, there are other sustainability aspects that concern our stakeholders. The aim of this CR report is to provide them with additional relevant sustainability information from Deutsche Telekom in the areas of environmental, social and governance (ESG). Within the CR report, we link to our other publications (Sustainability statement in the Annual Report and HR Factbook) in numerous places. This report is supplemented by further sustainability-related reports from the national companies, as well as up-to-date information in the area of corporate responsibility on our website and in other publications (see below).
The CR report 2025 is a publication of Deutsche Telekom AG and is also available in English. In case of doubt, the German version is authoritative.
Structure of the online report
The homepage provides an overview of the highlights from the reporting period. From there, you can access the four central areas of our CR report: CR Strategy, Environment, Social and Governance. There we provide information on our sustainability strategy as well as topic-related goals and progress made in the reporting year – from the perspective of our Group and our four operating segments Germany, the USA, Europe and Systems Solutions.
Our four central areas are supplemented by an interactive KPI Tool. There, users can view the most important sustainability-related key figures individually. The key figures are presented at group, segment and unit level with a four-year trend.
In addition to the report, there is the CR Facts. There, individual Deutsche Telekom departments provide direct information about their sustainability-related projects and measures. The CR Facts can be opened at any time via the footer of the report and is also updated during the year.
In the footer of the report, there are also links to the Download center, the glossary and other relevant websites.
Some figures in this report were generated with the support of artificial intelligence (AI) and have been labelled accordingly. All models and content used are properly licensed. In line with our digital responsibility, we ensure a respectful and responsible approach when depicting people.
Scope, reporting period and target groups
The CR report 2025 and the interactive KPI tool relate to the Deutsche Telekom Group with its 326 fully consolidated companies and thus to the segments and national companies; deviations are marked accordingly.
Like the Annual Report, this CR report covers the period from January 1 to December 31, 2025. CR reporting is carried out annually. The CR report 2025 thus follows on from the report 2024. The release date is May 19, 2025.
With this CR report, we are specifically addressing the following stakeholders of Deutsche Telekom:
business partners
analysts and investors
CR ranking and rating agencies
employees

Consideration of international reporting standards
The CR report 2025 and the KPI tool were prepared taking into account various international reporting standards and frameworks. Selected content is assigned with reference to the guidelines of the Global Reporting Initiative (GRI) and criteria of the Sustainability Accounting Standards Board (SASB). In addition, we report selected Principal Adverse Impacts (PAI) disclosures in accordance with the Sustainable Finance Disclosure Regulation (SFDR) as well as industry indicators from the GSM Association (GSMA) for the telecommunications industry.
On a separate page of the report, we present how our business activities relate to selected Sustainable Development Goals (SDGs) of the United Nations (UN).
The CR report 2025 also serves as a Communication on Progress (CoP) report for the UN Global Compact.
