Carbon Intensity ESG KPI Deutsche Telekom Group KPI
Carbon Intensity ESG KPI DT Group in Germany KPI

Since 2016, we have reported on the Carbon Intensity ESG KPI . In contrast to the existing CO2 Emissions ESG KPI, the new ESG KPI shows the CO2e emissions in proportion to the transmitted data volumes. Using data volume as a reference parameter makes it possible to create a direct link to the performance of our networks.
Data assured by PwC. Data is partly based on estimates, assumptions and extrapolations. The calculation method was adjusted in 2017. Values cannot be directly compared to the previous year.
The ESG KPI figure also takes into account total CO2 emissions for all energy sources – fuel, gas, district heating and electricity, The data volume is composed of the transmitted IP data volumes (including Voice over IP , Internet, IP-TV).
The Carbon Intensity ESG 305-4 (Greenhouse Gas Emissions Intensity). This information is relevant for EFFAS KPI E02-01 (Greenhouse gas emissions Scope 1-3). It is furthermore relevant for criterion 13 (Climate-relevant emissions and objectives) of the German Sustainability Codex. It is also used for reporting on the Global Compact principles 7 (Precautionary approach) and 8 (Promoting environmental responsibility).
KPI is relevant for the GRI indicator GRITotal CO2e emissions (Scope 1 - 3) KPI

Since the 2016 CR Report, Deutsche Telekom has provided a general overview of all its CO2 emissions (Scope 1-3). To ensure comparability with the Scope 3 emissions presented in CO2 equivalents (CO2e), Scope 1 and Scope 2 emissions were converted into kilotons of CO2e. Emissions are presented along Deutsche Telekom’s supply chain. This allows for an overview of where most of the emissions are produced.
In 2019, market-based Scope 1 and 2 emissions totaled approx. 1.8 million metric tons of CO2e across the Group, marking a reduction of more than 20 percent compared to the previous year.
Scope 3 emissions were reduced by 11 percent to some 12.8 million metric tons of CO2e in 2019. The majority of emissions can be attributed to the procurement (in particular of devices and network technology) and 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.
The decline in CO2 emissions is primarily down to the conversion to green energy. We are now analyzing whether a reduction in energy consumption through all-IP will be offset by increases resulting from 5G, expanded network coverage, and higher quality fixed lines.

Total CO2e-Emissions (Scope 1 & 2 Emissions) KPI

Our CO2 emissions are largely driven by our electricity consumption. That’s why the table below contains very detailed information about the Group numbers for the Scope 2 emissions resulting from our electricity consumption. We differentiate between the market-based and location-based methods, thereby adhering to the GHG Protocol Scope 2 Guidance. Market- and location-based emissions are reported in CO2 equivalents (CO2e). This change was made in order to allow a transparent comparison between Scope 1 to 3 emissions and to be consistent with the requirements of the Science-Based Targets Initiative, to which the new target is also geared.
The leading reporting method is the market-based approach. This method is used to calculate emissions with a specific emissions factor (provider factor) per DT company. This factor depends on a company’s actual energy procurement (electricity mix); procuring renewable energy (direct purchase, certificates) reduces emissions.a)
In contrast to the market-based method, with the location-based method the emissions factors for the respective country are used (the country mix factor of the International Energy Agency (IEA)). A company’s actual energy procurement (electricity mix) is hence not taken into account, i.e., not even the procurement of renewable energy over and above the country mix.
Change compared to the previous year: The Scope 2 emissions calculated according to the market-based method are about 20 percent lower than in the previous year. The main reason for this is the direct purchase of renewable energy at T-Mobile US and the increased purchase of renewable energy certificates (RECS , GoO) at our national companies in Germany.

By reporting our direct and indirect CO2 emissions (Scope 1 & 2) in accordance with the Greenhouse Gas Protocol, we fully cover the GRI 305-1 (Direct GHG emissions) and GRI 305-2 (Energy indirect GHG emissions) and partially cover the E02-01 (Total Scope 1-3 greenhouse gas emissions) EFFAS indicator. This data is also relevant for criteria 11 and 12 (Usage of natural resources) and 13 (GHG emissions) of the German Sustainability Code. It is also used for reporting on the Global Compact principles 7 (Precautionary approach) and 8 (Promoting environmental responsibility).
Total CO2e-emissions (Scope 3) Deutsche Telekom in Europe* KPI

The majority of our total emissions can be classified as Scope 3 emissions . Scope 3 emissions are all emissions from the upstream and downstream value chain, which are generated in the supply chain, by business travel, commuter traffic ("upstream") or at the customer's premises by the use of products and services ("downstream"). Their recording is based on the globally recognized "Greenhouse Gas (GHG)" protocol.
The graph shows Scope 3 emissions from 2017-2019, classified by emission sources. Upstream emissions accounted for around 46% of Scope 3 emissions in 2019, while downstream emissions accounted for around 54%. The basic data used to calculate Scope 3 emissions are reported in the key figure tool. You will find more information on recording Scope 3 emissions along the value chain here.

By reporting this data, we fully cover the GRI 305-3 (Other indirect GHG emissions) and the E02-01 (Total Scope 1-3 greenhouse gas emissions) EFFAS indicator. This data is also relevant for criteria 11 and 12 (Usage of natural resources) and 13 (GHG emissions) of the German Sustainability Code. It is also used for reporting on the Global Compact principles 7 (Precautionary approach) and 8 (Promoting environmental responsibility).
CO2 compensation
Preventing greenhouse gas emissions is one of our top priorities. CO2 emissions that we are unable to prevent or reduce can be compensated by investing in certified climate protection projects in addition to devoting greater efforts to using renewable energy sources.
Telekom Deutschland compensated for just under 6,271 metric tons of CO2 in the 2019 reporting year.
These included emissions associated with our events (participants’ travel to and from the event, room usage, etc.) and certain products and services (e.g., conference calls or web conferences). Our Event Policy specifies the ways in which we compensate for emissions generated by events.
