Climate strategy: Cut Co2 emissions and improve efficiency

Our integrated climate strategy is the cornerstone of our climate protection activities. We aim not only to reduce our own CO2 footprint, but also to help our customers reduce their CO2 emissions. To do so, we have set ourselves ambitious goals and established measurement systems to monitor them. Last year we again achieved substantial improvements in our climate protection activities. 13

Our networks represent the basis for our products and services. Running them consumes vast amounts of energy and generates a large proportion of our CO2 emissions. One vital element of our climate protection goal is therefore to save electricity by achieving greater energy efficiency in our network operations. For example, the Biere data center (near Magdeburg, Germany), which went into service in 2014, is one of the world's most efficient data centers. Due to the increased demand for cloud services, we are expanding the data center and, at the same time, minimizing its impact on the climate. The new facility will consume almost 30 percent less energy than comparable data centers based on an energy mix featuring a high proportion of renewable energy.

We fully support employee mobility patterns that cause as little harm as possible to the climate and the environment. In 2016 we launched a scheme whereby employees in Germany have the chance to convert part of their salary to purchase a bicycle or e-bike. This not only saves resources but also benefits their health. What is more, it reduces CO2 emissions during rush hours. The offer has met with a broad response among our staff and over 1,400 employees have already taken advantage of the salary conversion option to obtain bikes.

When procuring company and service vehicles, we opt for efficient, low-consumption drive systems and, where economically viable, alternative drives. We achieved our goal of reducing the average CO2 emissions generated by all newly procured company cars and service vehicles in Germany to 110 g CO2/km by the end of 2015. In 2016 we set ourselves a new goal: 95 g CO2/km by 2020.


According to the SMARTer2030 study published by GeSI (Global e-Sustainability Initiative), information and communications technology will make it possible to avoid 20 percent of the world's greenhouse gas emissions in the year 2030. To exploit this vast potential is one of the goals of our integrated climate strategy. Take, for instance, Deutsche Telekom's AutoApp. It enables car owners to drive economically and avoid traffic jams – and, in doing so, reduces CO2 emissions. 12

A large number of products and technical services we offer make a major contribution toward an improved healthcare service. We provide applications that communicate patients' vital data to physicians via a secure channel on a regular basis. This makes it possible to check on patients with critical health problems – even when they are miles from a health center – and thus to improve the quality of their lives. In this way, hospitalization can be reduced, freeing up funds for improved deployment in the healthcare system. Another example of telemedicine is our smart emergency call system. It allows the elderly to maintain their independence and stay put in their homes for as long as possible. 3

Our solutions can also help conserve valuable natural resources. In 2016, T-Systems South Africa developed a smart water meter, which measures how much water is taken from a well or discharged from a water treatment facility. It also monitors and documents consumption within the supply network up to the end user. The consumption data, which is stored in the cloud, can be accessed from anywhere and provides an overview of current water usage. The system also allows potential leaks to be pinpointed and eliminated faster. 6
