Our integrated climate strategy

Our contribution to the SDGs

We designed our integrated climate strategy in line with our Group strategy. This is how we ensure our climate protection measures are closely connected with our core business. We have defined objectives and/or key performance indicators for each of the four aspects of our climate strategy (CO2 emissions, renewable energy, energy efficiency, and sustainable products).

The four pillars of our integrated climate strategy

We record all direct and indirect emissions using the globally recognized Greenhouse Gas (GHG) Protocol. The goal is to reduce our emissions by 20 percent by the year 2020 compared to the base year 2008 (excluding T-Mobile US). As we implement our measures to reduce CO2 emissions, we are focusing on areas with especially high energy consumption, such as our networks and data centers. This has already allowed us to moderately reduce our emissions over the past few years (excluding T-Mobile US), despite rapidly growing data volumes and the necessary network build-out. At the same time, we are expanding our proportion of renewable energy. However, the majority of our overall emissions are accounted for by indirect emissions (Scope 3 emissions img). That is why we are including our suppliers in our climate protection measures and also helping our customers reduce their CO2 emissions with relevant products and services.

CO2 emissions

We are researching and evaluating various options to increase our proportion of green energy. Possibilities include purchasing energy certificates from renewable sources and using cogeneration (“CHP”) plants to generate our own renewable energy. Some national companies are setting a great example: T-Mobile Austria and OTE in Greece obtained 100 percent of their electricity from renewable sources in 2018. When purchasing electricity, we take a variety of sustainability factors into consideration on a Group-wide level. These include, for instance, the average emission factor of the electricity mix (i.e., the amount of emissions for every kilowatt hour of electricity used) and the proportion of renewable energy. These parameters help us make our energy mix more transparent and increase the share of energy obtained from renewable sources at our company.

Renewable energy

Because the operation of our network infrastructure calls for a considerable amount of energy, we are investing in modernization and energy-efficient technology. For instance, we are migrating our network infrastructure to IP img technology, which is not only more powerful, but also consumes less electricity than existing technologies. In addition, we are working to process data traffic from no more than a few, particularly efficient data centers. Higher energy efficiency also always brings a reduction in CO2 emissions. In order to measure our progress, we use two key performance indicators (KPIs). They show the relationship between our energy consumption or carbon footprint and transported data volume.

Energy efficiency

Many of our products and services provide sustainability advantages. They can help reduce energy consumption and CO2 emissions, improve healthcare, and make logistics more efficient. Using the “Sustainable Revenue Share” KPI img, we record the proportion of our overall sales accounted for by sustainable products. “Sustainable products” are products that provide sustainability advantages and that do not entail any significant sustainability risks. We also use our “Enablement Factor” ESG KPI to correlate our emissions with the potential savings for our customers. This helps us evaluate our overall performance in relation to climate protection.

Collaborating for climate protection
Effective climate protection calls for joint efforts on the part of business, politics, science, and society. That is why we are involved in numerous German initiatives, such as the 2° Foundation and the Federal Ministry for the Environment’s climate protection initiative for business, as well as a number of international associations. One of these is the Global e-Sustainability Initiative img (GeSI img). As an industry association, GeSI’s vision is to help make society greener and more climate-friendly with the help of ICT img solutions.
