Environmental Sustainability

We strive to manage environmental impacts effectively and use natural resources efficiently. In this context, we focus on renewable energy, energy efficiency solutions, waste management, water conservation, meeting community needs, and enhancing societal welfare. Additionally, we strengthen our brand reputation and value by placing sustainability at the highest level through strategic collaborations. Environmental Training, offered as e-learning at Türk Telekom, was assigned to all our employees in 2025.

Data Centre Investments with Environmental Considerations

Data centres are inherently highenergy-consuming critical infrastructure facilities. As Türk Telekom, we are undertaking a comprehensive transformation process to make these energy-intensive structures more efficient and sustainable. Along with three commercial data centres in Ümitköy, Esenyurt, and Gayrettepe, we also operate Türk Telekom’s own data centres in Ümraniye and Ahlatlıbel.

In line with our energy efficiency goals, we aim to reduce the PUE (Power Usage Effectiveness) value of our existing data centres to 1.4, and for newly constructed data centres, to 1.2. As of 2024, the average PUE value of our existing data centres is 1.55, down from 1.8 in 2020. This value is in line with the global average and is below the levels typically seen in Türkiye, which range from 1.7 to 1.9.

In addition, we are implementing various measures to reduce our water consumption in our data centres. The rainwater recovery system used at our Esenyurt data centre helps optimise our use of natural resources, while the misting technology applied to the outdoor units of the DX cooling systems at our Ümitköy data centre minimises our water consumption and increases cooling efficiency.

Additionally, with the Artificial Intelligence-Supported Cooling Optimisation Project, which we plan to implement at our Ümitköy data centre, we aim to reduce cooling energy consumption by 20%. This project, which is planned to be completed by the end of 2025, aims to achieve energy savings by managing cooling systems in the most efficient way through artificial intelligence algorithms.

Electric Vehicle Charging Network Project

Türk Telekom Ventures launched the E4 Charge-Electric Vehicle Charging Network project, entering the Electric Vehicle Charging Operations market as a “Charging Network Operator.” This project aims to contribute to sustainable transportation solutions and promote the use of environmentally friendly vehicles. As electric vehicles become more widespread, this initiative will significantly contribute to our efforts to reduce environmental impacts and promote the use of clean energy.

Sustainable Innovation and Collaborations

Türk Telekom continues contributing to its sustainability goals through innovation and technology partnerships. For example, we collaborated with Erzurum Atatürk University on a five-year project, contributing to the development and improvement of new products and services. Students involved in the program, which began in the spring of 2022, had the opportunity to work on innovative technology projects such as blockchain, NFTs, artificial intelligence (AI), and IoT alongside Türk Telekom teams. This collaboration significantly contributed to the development and excellence of our company’s products and services.
