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 2026.

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 2025, the average PUE value of our existing data centres is 1.54, 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. With the efficient halls we have recently commissioned, we anticipate that this value will approach 1.5 within 2026.

Ümitköy Data Centre - Artificial Intelligence Cooling Optimisation Project

In addition, by dynamically controlling our cooling capacity with artificial intelligence, we set out to achieve a 25% energy saving and reduce our carbon footprint in the data centre. By the end of 2025, efficiency was calculated at 28.4%, without taking into account the effect of outside ambient temperature. The annual average efficiency for 2026 is expected to be 20% higher.

Electric Vehicle Charging Network Project

We are steadfastly continuing our investments in electric vehicle charging infrastructure to support environmental sustainability and contribute to reducing carbon emissions. As the global shift towards reducing fossil fuel use and protecting the environment gains momentum, Türk Telekom has taken a strategic step towards contributing to the development of a sustainable transportation ecosystem by obtaining an Electric Vehicle Charging Network Operation licence through TT Ventures.

Recognising that electric vehicles play a critical role in reducing dependence on fossil fuels and promoting low-carbon transportation, we aim to support clean energy use by offering nature-sensitive and environmentally friendly charging solutions. With the investments we have made in this direction, we aim to meet the changing needs of electric vehicle users with safe, sustainable, and eco-friendly solutions. As part of the financial implications of this strategic approach, we generated 3.5 million TL in revenue from electric vehicle activities in 2025.

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.
