Strategic and organizational approach to sustainability

We see ourselves as a responsible company and have made that a core element of our Group strategy. We are committed to implementing sustainability along our entire value chain – and to playing an important role in meeting today’s environmental, economic, and social challenges. We are expressly committed to the principles of the United Nations Global Compact, the German Sustainability Code, and the Code of Responsible Conduct for Business. In addition, as already outlined, we support the United Nations Sustainable Development Goals (SDGs).

Our CR strategy focuses on four key areas in which we want to act as a role model:

  1. Our commitment to climate-neutral business practices
  2. Our determined efforts to ensure the circularity of our products and services
  3. Our commitment to diversity, equity, and inclusion (DE&I), and our investment in training for our employees
  4. Our determination to help shape a digital society that is based on fundamental democratic values and in which all people can participate safely, competently, and with autonomy

Good governance is the foundation of these strategic pillars. For us, this includes an internal control system and a risk management system, including a compliance management system which is aligned with the Company’s risk situation. Maintaining data protection and security, cyber security, engaging with the fundamental principles of digital responsibility, upholding human rights, shaping sustainable supply chains, investing capital based on ecological and social criteria, and ensuring communication about our environmental and social sustainability activities is transparent are additional meaningful aspects of good governance.

Our Board of Management bears overall responsibility for CR: it discusses and decides on the most important strategic guardrails and objectives. The Board of Management is advised and supervised in this task by the Supervisory Board. The Group Corporate Responsibility (GCR) unit develops the Group-wide CR strategy, including the associated policies and guidelines. Its aim is to further develop our corporate culture, particularly in terms of sustainable innovation, ecological business operations, and social responsibility. Since 2022, the Chair of the Board of Management has been responsible for GCR. The Supervisory Board and the Board of Management are thereby emphasizing how seriously Deutsche Telekom takes its social and environmental responsibility. The Board of Management is informed every quarter about the status of the most important sustainability indicators in the Group Performance Report. During the course of the year, the Supervisory Board is also regularly informed by GCR about the sustainability strategy and the progress made in implementing it. Furthermore, a training workshop on the role of the Supervisory Board as part of new sustainability requirements was held in 2023. Additionally, the former Global CR Board was realigned in the reporting year as a Group-wide steering committee and preparatory body for the Board of Management.

The different Group business units and segments are responsible for implementing the CR strategy. A governance structure based on the overall responsibility of the Board of Management was established in the operating segments in 2023: overarching CR responsibility for the segment lies with the relevant management. This delegates content adaptation and implementation of the Group sustainability strategy to CR segment leads. The CR segment controllers provide support to establish processes for capturing, consolidating, and analyzing ESG KPIs in their segment. Specific measures are driven by the CR managers of each unit, who work together within the international CR Manager Network.

Our values and basic principles are anchored in our Guiding Principles, the Code of Conduct, the Code of Human Rights, and other subject-specific policies. The cornerstones of our sustainability management activities are formally set out in our CR Policy, which is binding for all Group units. In order to continue driving forward implementation of our CR ambitions across the Group, the Board of Management adopted the refined and revised CR Policy in February 2023. We then introduced a process for implementing the revised version throughout the Group. At the end of 2023, the CR Policy had been enforced at 75 of 135 Group companies; the rollout will be continued in 2024.

We will publish detailed information on the CR Policy in our 2023 CR Report.

We record ESG data as part of our CR controlling and reporting activities. We use this data to calculate our ESG KPIs, which we use to measure and manage our CR performance. The non-financial performance indicators “energy consumption” and “CO2 emissions” (Scope 1 and 2) that are relevant for remuneration are essential elements of the Group’s higher-level controlling processes. This also applies to other ESG KPIs, such as the Energy Intensity ESG KPI and the Sustainable Packaging and Return of Devices circular economy KPIs. Alongside the ESG KPIs, we also report other metrics and data with the aim of meeting internal and external transparency requirements.

Growing numbers of investors are focusing on sustainability aspects in their investment decisions (Socially Responsible Investment, SRI). SRI investment products consist of securities from companies that have been reviewed based on environmental, social, and governance (ESG) criteria. The development of demand from socially responsible investors for the T-Share is an indicator we can use to assess our sustainability performance. The Socially Responsible Investment ESG KPI indicates the percentage of Deutsche Telekom AG shares held by such investors. To do this, we monitor sustainably managed shares at fund level. For better comparability with other companies, the total number of shares given pertains to the number of Deutsche Telekom shares in free float. Our Group-wide commitment to greater sustainability is paying off: as of December 31, 2023, around 32 % (prior year: 31.3 %) of all T-Shares were held by investors who show concern for environmental, social, and governance criteria in their investment choices.

As part of our CR strategy, we have taken part successfully for many years in ESG ratings, which we select based on reputation, relevance, and independence. When rating agencies give high marks to our social and ecological commitment, the T-Share is included in the financial market’s sustainability indexes. In 2023, the T-Share was once again listed in all sustainability indexes relevant for us as a company.

Sustainable Development Goals (SDGs)
Goals that form the core of the 2030 Agenda, which the member states of the United Nations adopted in 2015 to ensure sustainable global development. The aim is to enable economic development and prosperity – in line with social justice and taking account of the ecological limits of global growth. The Agenda applies equally to all nations of the world. The 17 SDGs define goals to reduce poverty and hunger, promote healthcare and education, enable equality, protect the environment and climate, and make consumption sustainable.
