We designed our integrated climate strategy following our Group strategy "Leading European Telco". This is how we ensure that our climate protection measures are closely connected with our core business. Our integrated climate strategy includes four aspects of climate protection: CO2 emissions, renewable energy, energy efficiency, and sustainable products. For each one of these aspects, we have defined goals and key figures.
To help us achieve this goal, we record all direct and indirect emissions using the globally recognized 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). We uphold this ambitious climate goal despite the challenges arising from fast growing data traffic and the consequent ongoing network expansion. In order to achieve this, we are focusing on areas with especially high energy consumption, such as our networks and data centers. We have already achieved a moderate reduction in emissions (excluding TMUS) over the past few years. To achieve our goal, we also want to increase the share of renewable energy.
We are evaluating various options to increase our share in green energy. This includes purchasing energy certificates from renewable sources, generating our own renewable energy such as through the use of cogeneration (“CHP”) plants. 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 2017. We have introduced parameters throughout the Group that can be used to assess electricity procurement in terms of sustainability. These parameters help us make our energy mix more transparent and increase the share of energy obtained from renewable sources at our company.
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 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. 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.
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. Since 2016 we have been measuring the amount of CO2 emissions that our customers can reduce by using our products and services. With our Enablement Factor ESG KPI, we set our emissions in relation to potential savings for our customers in order to evaluate our overall performance in climate protection. Moreover, we use the Sustainable Revenue Share ESG KPI to measure the share of sustainable products. These are products that provide sustainability advantages and that do not entail any significant sustainability risks.
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 a number of German initiatives, such as the 2° Foundation, and international associations. One of these is the Global e-Sustainability Initiative (GeSI ). As an industry association, GeSI's vision is to help make society greener and more climate-friendly with the help of ICT solutions.
