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. For the first time, the market- and location-based emissions for 2017 and 2018 are indicated in CO2 equivalents.
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, PPA) at our national companies in Germany and Greece.
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).
