CEO T-Systems International GmbH and
Board Member of Deutsche Telekom

The effects of environmental degradation and rising temperatures are exerting a significant and tangible impact. The current geopolitical tensions have also changed the awareness and behavior of consumers, companies, and investors all over the world. A new mindset in society is requiring companies to rethink and commit to a more sustainable present. This makes it our clear moral responsibility – and, following the German Constitutional Court’s ruling in April 2021, our legal obligation as well.

T-Systems announced its participation in the Climate Neutral Data Centre Pact (CNDCP) in May 2021. This involves us in a commitment to make datacenters climate neutral by 2030. The self-regulatory initiative includes an ambitious set of goals, which cover energy efficiency, recycling of surplus heat, and water conservation. Under the banner “The Green Deal needs green infrastructure,” the Pact affirms our commitment to the European Green Deal. We believe our services will play a central role in decoupling economic development from emissions growth.

But our infrastructure is not the only thing going green. Our services are making the entire economy greener. Our clients can decrease their energy use by migrating from their own IT infrastructure to the T-Systems Cloud Solutions. Technologies such as the Digital Twin take processes out of the physical world, help conserve our planet’s resources and decarbonize production. The Gaia-X initiative creates the basis for exchanging sustainability data along the entire supply chain, enabling informed environmental decisions. But as society generates ever-growing volumes of data, our datacenters need to be sustainable too in order to reap the full environmental benefits of digitalization. That’s why we have committed to this initiative, alongside some of our major partners.

This initiative is part of a more broadly-based drive at Deutsche Telekom. The entire Group has obtained energy exclusively from renewable sources since the beginning of the year under review. We are also developing innovative green technologies for Cloud computing img at our datacenter in Biere, in partnership with the Fraunhofer Institute. Sustainability is the key focus of our corporate responsibility. We are targeting climate neutrality across our entire value chain by 2040.

At T-Systems we are committed to offering services which drive sustainability with our clients and partners. Joining the CNDCP reflects this. Our subsidiary Detecon, for instance, makes an important contribution to T-Systems with its consulting offering and sustainability expertise. We are going to challenge ourselves to reach our sustainability goals and indeed surpass them. It is the morally responsible thing to do – for ourselves and for future generations.

CO2 App img from T-Systems MMS promotes environmentally friendly mobility behavior
The sustainability goals of many companies are often still limited to internal processes. But employees can also save emissions on their way to work, for example, by adopting more environmentally conscious behavior.

The Green Magenta solution EcoShift allows the mobility behavior of employees to be recorded in a CO2 App. This enables savings to made, and the company can be more environmentally friendly. The App was developed for Deutsche Telekom and is designed to help employees reduce their emissions. It is also being tested at Deutsche Telekom as a pilot. The App allows anonymized tracking of work routes and means of transport, and the employees’ data is forwarded directly to the company. This means that extrapolations can be made using the dashboard, for example in the area of the mobility budget. In addition, users are shown comparative values on their end device so that they can individually optimize their own route. The aim of the platform is to sensitize employees, i.e. encourage them to interrogate their own mobility behavior and in the best-case scenario, to foster an awareness of sustainability. The value added for companies lies in the real data anonymized under data protection regulations. Time-consuming surveys with inaccurate data are no longer necessary. This makes it possible for companies to achieve their sustainability goals in Scope 3.

Sustainability Awareness Game

Sustainability is a much-discussed topic and is becoming increasingly important for companies. How T-Systems is dealing with it, what initiatives are already underway and what everyone can do themselves: The susTain awareness game provides information.

The interactive training provides information about sustainability at T-Systems in a game-based approach. A tour of a five-room virtual office building shows initiatives already underway to improve T-Systems’ footprint and offerings that support customers in their sustainability goals.

The game provides insight into the UN Sustainable Development Goals (SDGs) and the activities of T-Systems and the Group contributing to this. Whether it’s green datacenters or product development with a view to the carbon footprint – there’s plenty to discover.

Employees can learn how everyone can make T-Systems’ offering greener, how T-Systems involves suppliers and how energy-intensive datacenters can still operate more sustainably.

Participants who complete all the rooms and answer the test questions correctly will receive a certificate verifying that they have achieved a high score in sustainability at T-Systems.

Health Insurance and ID Card on your Smartphone: BARMER Commissions T-Systems and VERIMI

Leading German health insurer Barmer has commissioned T-Systems and Verimi to supply and manage digital identities for its 8.7 million policyholders. 

Digital identities are provided through ID services. T-Systems relies on the Verimi ID Wallet for this purpose. As part of the approval procedure for interoperable user accounts of the Federal Ministry of the Interior and Community (BMI), the Federal Office for Information Security (BSI) evaluated the eID identification procedure and the Verimi App-based authentication using a PIN. Based on the documents submitted by Verimi, the BSI had confirmed in 2020 that the procedure is suitable for the trust level. T-Systems and Verimi use these procedures evaluated by the BSI when mapping digital identities for Barmer.

Legal obligation for insurers from 2023
The smartphone will become an electronic health insurance card. Policyholders will receive a digital twin of their chip cards on their smartphones: digital identities will enable access to data and applications. Like the card, they will also serve as proof of insurance. Health insurers will have to offer this service by 2023. The basis for this is the Digital Care and Nursing Modernization Act (DVPMG) which came into force last year.

Telekom and Verimi will integrate the wallet into the BARMER App img. The stored electronic ID card and biometric processes such as Face ID ensure unique identification. This will allow users to access the electronic patient file in a highly secure manner, for example, for electronic prescriptions. Telekom and Verimi want to offer their solution to other insurers. In principle, the technology is suitable for almost all areas of online social life.

Signal for the Federal Government and the European Union
Digital identities give citizens more sovereignty on the Internet. The Federal Government and the European Union are driving this development forward. The companies therefore hope that this deal with BARMER will also send a signal to the public sector. The Federal Government and the private sector want to work together to help digital identities achieve a breakthrough. This is a strategic issue for Telekom. The company has been a Verimi shareholder since 2017. 21 German companies have a stake in Verimi, including a raft of DAX companies.

Sustainability Consulting by Detecon

Detecon’s offering makes an important contribution to T-Systems’ sustainability expertise. Businesses have a key role to play as the largest contributors to greenhouse gas emissions and ecosystem loss. Collectively, they have the necessary robustness to enable an environmentally sustainable future.

Detecon has developed its own sustainability consulting approach for companies. It focuses on one of the most important levers for sustainable development: the use of digital technologies. Used correctly, they can develop their full potential to promote sustainability.

Detecon’s sustainability approach comprises six steps that enable clients to change the sustainability culture within their company. Firstly, the challenges and fields of action are defined and the sustainability goals are determined. The second step involves recording the initial situation. Existing methods and strategies are documented and the data situation is then analyzed for recording the initial values. The ambitions for sustainability are then determined on the basis of various influencing factors. In step four, the strategy on how to achieve the strategic goals is then determined, along with short and long-term measures. Step five then deals with long-term and company-wide anchoring of the goals and measures with a view to sustainability. Finally, change management is conceptualized to establish the new climate-neutral culture throughout the company.

Better Digital Offering through New School Network

Many schools are setting out to introduce new methods for imparting knowledge. Digital media play a key role for the new interactive formats. The new network of the Oberpleis School Center in Königswinter is a future-proof platform for rolling introduction of digital services that open up completely new educational opportunities for schools. In future, new media such as digital whiteboards and touch panels can be used in lessons and in organization of activities in schools. 

The expandable VoIP telephone system offers its users a wealth of potential additional functions. In addition, the telephone system has support from the manufacturer. Problems can be solved even faster by remote access. Travel times for technicians are significantly reduced.

The harmonized infrastructure with its new technical foundation can now be administered with much less effort – the console provides clear information about the status of the individual components: defective elements are identified and replaced more quickly. 

The new school network also offers a host of other options for the future development of services on the school campus. Clubs using the premises can also access network resources easily and securely. The simplified administration makes it all possible. And this is by no means the end of the road: “We have set a new standard with the network that can be scaled effortlessly with an increasing number of end devices and users,” said Frank Laska, the T-Systems Project Manager. Sales manager Gerald Renner adds “The rollout to other schools in Königswinter is already planned. They, too, should be given the opportunity to use new options for digitalization in education.” The central server room and the new, modern security architecture form the basis for this: step by step, the nine other school locations are going to link up with this central platform and benefit from the advances made.
