DTAG becomes the first telecommunications company to achieve group-wide net-zero emissions
Greenhouse gas emissions reduced by more than 94% compared to 2017
Total emissions reduction amounts to approximately 28 million tonnes of CO₂
Deutsche Telekom is implementing energy-efficient measures, electric mobility, and energy-saving buildings. However, the Group’s environmental ambition does not end with this milestone – by 2040, Deutsche Telekom aims to achieve carbon neutrality across its entire value chain.
“We are proud to announce that we have achieved carbon neutrality across the Group’s operations. Since 2017, we have reduced emissions by more than 94% – exceeding our target by 4 percentage points. The remaining emissions are offset through CO₂ removal projects. As a result, we are part of the first telecommunications group to be truly carbon-neutral in its operations. Together with Slovak Telekom, we are actively contributing to mitigating climate change,” says Melinda Szabó, CEO of Slovak Telekom and T-Mobile Czech Republic.
The key tools include:
Green electricity: Since 2021, Slovak Telekom has been using 100% green electricity across its network. It has also signed long-term power purchase agreements (PPAs), ensuring price stability while enabling the construction of new solar and wind parks. Large-scale battery storage systems at multiple sites help stabilize the network and serve as backup storage for renewable energy when wind or solar conditions are not sufficient.
Energy efficiency: Telekom is making significant investments in energy efficiency, including intelligent network management and modern technologies. Despite increasing energy demands driven by digitalization, Slovak Telekom reduced its energy consumption by 13.9% between 2021 and 2025. These investments not only lower energy costs but also significantly reduce the company’s carbon footprint.
E-mobility and building modernization: The ongoing transition of the Group’s fleet to electric vehicles reduces operational and maintenance costs. In administrative buildings, costs and emissions are lowered through flexible space usage, intelligent management systems, and modernized heating technologies.
In 2024, Slovak Telekom received the prestigious Via Bona award in the Responsible Large Company category, confirming its long-term and consistent approach toward achieving carbon neutrality.
“Digitalisation and decarbonisation are not only investments in technology, but above all in a sustainable future. Success is only possible if it is both environmentally and socially responsible. That is why we set our goals in line with the needs of the planet and work together with partners across the Group and in Slovakia to achieve them,” says Pavel Hadrbolec, Chief Financial Officer of Slovak Telekom and T-Mobile Czech Republic.
Achieving carbon neutrality in own operations is only the beginning. By 2030, the Group aims to reduce emissions by 55% across all three scopes – including production, delivery, storage, and distribution of equipment, as well as its use by customers. By 2040, the entire value chain is set to become net-zero.
