Climate protection from 2020 onward – new climate goal and revised climate protection strategy

Our contribution to the SDGs

In 2018, we revised our integrated climate strategy, devising a new Group-wide climate goal for the period beyond 2020, our current target year. The main difference between the new climate goal and the previous one is that the former takes into account emissions produced by T-Mobile US and arising from the upstream and downstream elements of the value-added chain (Scope 3 emissions img). We calculated this goal based on the methodology recommended by the Science Based Targets initiative.

In light of growing data traffic and the network build-out, we expect energy consumption to continue to rise over the coming years. To fulfill the requirements laid down by the Science Based Targets initiative, however, we are taking measures to boost efficiency and using electricity generated by renewable power sources. We have decided to switch to using 100 percent renewable energy for our entire power consumption by 2021. As things currently stand, we already derive 52 percent from renewable sources. We have set ourselves the additional goal of cutting our emissions by 90 percent (compared with 2017) in the period to 2030.

Our goal for emissions arising from the upstream and downstream elements of the value-added chain is to reduce the emissions generated per customer in the most important categories (purchased goods and services, capital goods, and product lifecycle) by 25 percent per customer. Among other things, we also plan to run workshops with our key suppliers in a bid to derive measures and agreements for reducing CO2 emissions.

In addition, we are examining how we can boost the potential of Deutsche Telekom’s products and solutions (“enablement”) to protect the climate even further – for instance by developing new sustainable products.

Climate protection at T-Mobile US

Our contribution to the SDGs

In the United States, T-Mobile US has set itself particularly ambitious climate protection goals and is looking to cut its CO2 emissions by 95 percent between 2016 and 2025. This will primarily be achieved by using Power Purchase Agreements (PPAs) to increase the share of renewable energy to 100 percent by 2021. In this connection, T-Mobile US signed up to the RE100 initiative in 2018. This initiative brings together companies who are endeavoring to obtain 100 percent of their energy requirements from renewable sources. T-Mobile US has also set itself the goal of cutting emissions in the upstream and downstream value chain (Scope 3 emissions). In the United States, the majority of Scope 3 emissions are generated in the upstream value chain. The aim is to reduce total Scope 3 emissions per customer by 15 percent compared with 2016.

Scope 3 emissions - a building block for a new climate target

Indirect emissions along our value chain, or Scope 3 emissions img, make up the majority of our total emissions. For climate protection to be credible, these emissions must be recorded so that targeted measures can be implemented at company and product level to reduce our carbon footprint.

  Data assured by PwC. For detailed assurance comments see „DT Group in Germany“ and „T-Mobile USA“. Values for 2016 have been adjusted retrospectively.

We have been disclosing the Scope 3 emissions generated throughout the Group since 2016. In 2018, these emissions amounted to around 14.4 million metric tons of CO2e, which is roughly equivalent to the level recorded for the previous year. At around 5.7 million metric tons of CO2e, emissions in Germany were also at the same level as the previous year. The majority of emissions can be attributed to procurement (in particular of devices and network technology) and the use of our products and services (for sold or rented) fixed-line and cell phones, routers, and media receivers, and for products such as laptops or television sets that our customers use so they can make the most of our services. Of equal importance are the emissions resulting from the manufacture and transportation of technology for establishing our networks.

In 2018, we modified the method for calculating Scope 3 emissions. To ensure comparisons can be made with the previous year’s values, we have recalculated the data for 2017 using this method.

1)Corrections for 2016 led to some changes being made compared to the previous year’s report.

2)The 2017 rise resulted from the national companies in Albania, Macedonia, and Montenegro, and T-Systems units being recorded for the first time, which contributed to the 27-percent increase of the Group value compared to 2016.

Due to the large proportion of emissions in our supply chain, we have a responsibility to reward our suppliers for eco-friendly activities and thus also to reduce our Scope 3 emissions. Since as early as 2016, we have been disclosing our activities to bring on board suppliers under the auspices of the supplier engagement rating of the CDP img (formerly the Carbon Disclosure Project). This rating assesses how well companies have been able to integrate the topic of climate protection into their supply chain. In 2018, we once again improved on the previous year and achieved an “A”, as we did in 2016. This has secured our place on the Supplier Engagement Leader Board. An important step in achieving this was calculating the supplier-specific emission intensities based on supplier responses to the CDP Supply Chain Program. This involves calculating the ratio between a supplier’s overall emissions (Scope 1 and 2 and Scope 3 from the upstream supply chain) in grams and the supplier’s overall sales. As we know the procurement volume attributable to a given supplier, we can also calculate our proportion of the supplier’s emissions based on emissions intensity. Our calculations do, however, depend on our suppliers providing complete and correct information.

Employee commuting
In the reporting year, we carried out a Group-wide survey on commuting and more than 71,000 employees took part. In the year under review, we recorded a reduction in emissions arising from commuter traffic, with levels dropping from 762,000 in 2017 to 538,000 metric tons of CO2e. A more detailed analysis and a comparison with other companies will help us in 2019 to understand how we can reduce these emissions in the future while taking into account the mobility needs of our workforce.

Recognition of leadership role in climate protection

Erneute Aufnahme in das CDP-Ranking In the CDP img ranking again
In 2018, we made it onto the CDP Climate A List for the third time in a row. The CDP ranking recognizes companies that don’t just exhibit transparency when it comes to climate change, but are also aware of how climate change affects their business, actively manage the opportunities and risks associated with climate change, and are pioneers and role models in their approach to climate protection. Under the CDP, we have reported Group-wide not only Scope 1 and Scope 2 emissions img but also Scope 3 emissions img from our business operations in Germany and almost all our international companies since 2014.

Our strategy for climate-friendly mobility

Our contribution to the SDGs

We pursue a three-pillar strategy to ensure a climate-friendly fleet management strategy:

  • Rightsize: selecting appropriately sized, energy-efficient, low-emissions cars. In addition, the Green Car Policy img creates incentives for drivers of company cars to increasingly select smaller, more efficient cars.
  • Economize: encouraging a fuel-efficient, low-emissions driving style with driver training courses.
  • Substitute: testing, piloting, and using alternative mobility concepts.

We plan to keep average CO2 emissions levels of all of the new cars we purchase (company and service vehicles) below 95 g CO2/km by the end of 2020 in Germany. With this in mind, we are looking to increase the number of vehicles with alternative drive concepts. For a while now, we have been using a certain number of vehicles powered by natural gas and electricity. We currently favor natural gas, especially for service vehicles. In addition, we are promoting the use of electric drive systems for service applications in specific pilot projects and usage scenarios. Efficient diesel vehicles will also continue to be used in the years ahead for economic reasons. Vehicles with gasoline engines generate higher CO2 emissions and higher costs than their diesel equivalents, so they only offer a viable alternative in low-mileage applications.

Natural gas as an alternative: new fuel card for natural gas filling stations
Our fleet management team checks whether natural gas filling stations are available at a particular location before offering vehicles powered by this fuel. In the year under review, a new compressed natural gas (CNG) fuel card was added to the portfolio with a view to using as many of Germany’s 860 or so natural gas filling stations as possible. The CNG fleet grew to 60 vehicles in 2018. Around 140 further such vehicles currently on order will soon join these. The focus is on service vehicles due to the models available at present on the market. Given the efficiency and environmental benefits of CNG, we will continue promoting the use of natural gas vehicles. We believe they offer significant further potential as an interim solution on the way to electric mobility.

Electric vehicles: pilot projects, vehicle tests, and expanding the charging infrastructure
To make the most of the benefits of electric mobility in the medium term, we have been supplying electric vehicles for pilot projects and specific usage scenarios since 2014. In addition, electric vehicles were tested with a number of service units throughout Germany in 2018 to ascertain their suitability for various applications. This revealed that it is possible to use electric vehicles for activities that can be planned, as long as the necessary charging infrastructure is in place and journeys are within a radius of 100 km.

On the basis of these findings, we will be joining a number of other prestigious companies from mid-2019 onward and participating in the “Renewably mobile” support project. In this connection, we have undertaken to purchase a total of 110 electric vehicles as well as charging points. These vehicles will be introduced throughout Germany – mostly service vehicles, but also electric rental cars and an e-shuttle.

The newly founded company Comfort Charge has been helping further expand the charging infrastructure for electric vehicles since the beginning of 2018 by upgrading the existing telecommunications infrastructure in Germany to create a nationwide e-charging network. For further information, please refer to the section on customers.

Extensive choice of mobility options
One of the ways we encourage our commuting employees to actively protect the climate is by enabling them to buy discount season tickets for local and regional public transportation. Regrettably, demand has been falling for around three years now and fewer of these tickets are being issued. We also rely on other modern forms of mobility including our shuttle service, which we have been offering for ten years, loaner bikes for getting around in the city, and rental cars. Midway through 2018, the first three Deutsche Telekom locations were equipped with a charging infrastructure for employees’ electric vehicles. Darmstadt, Frankfurt, Düsseldorf, Berlin, and Hamburg will follow early in 2019.

On the go and green: e-bikes, shuttles, and rental bikes
Since 2015, we have offered our employees in Germany the chance to purchase a bicycle or e-bike through deferred compensation schemes as a green and healthy alternative. With the support of Telekom MobilitySolutions, employees can lease a bicycle through their employer for three years. The monthly payments are subtracted from the employee’s gross salary. The new offer has met with a tremendous response right from the off. By the end of 2018, over 5,100 colleagues were already making use of this option – an increase of 100 percent compared to the previous year. Since 2018, employees have also had the option of obtaining a second bicycle through deferred compensation schemes.

We provide shuttle services between different locations, e.g., to the Cologne/Bonn airport or the Siegburg ICE train station to reduce the carbon footprint of business trips. Roughly 125,000 passengers used this service in 2018. Employees can use an app or visit the intranet to conveniently book a shuttle.

A total of 240 rental bicycles, including some e-bikes, are also available at more than 30 Deutsche Telekom locations in Germany for employees to get to their business appointments within the city. In addition, we have supplied a further 50 bicycles in five cities as a mobility solution for temporary student workers in the service team.
