Our approach for more renewable energy
In order to specify our integrated climate strategy, we are currently working on suitable goals and strategies in the field of renewable energy. One thing is clear - we want to increase the share of renewable energy across the Group and thus reduce our carbon emissions. For this, we want to procure more power from renewable sources, but also buy corresponding power certificates. Where it is possible and sensible, we are already investing in our own power generating systems, such as the construction of cogeneration plants or the installation of solar systems.
Since 2016, we have been capturing the ESG Renewable Energy KPI .The KPI is calculated based on the share of renewable energy in total electricity consumption. This is how it makes our progress in the area transparent. In 2017, the figure was at 41 percent across the Group (33 percent in 2016).
In addition, we have also introduced parameters throughout the Group that can be used to assess electricity procurement at our national companies in terms of sustainability. These parameters help us make our current energy mix transparent and increase the future share of energy obtained from renewable sources.
Clean energy generation: New solar power systems installed
At our technology sites in Germany, we are increasingly relying on solar energy. By the end of the year 2017, we were already operating a total of over 300 of our own solar photovoltaic plants. Two new plants were added in the reporting year. In total, the plants have a capacity of 4,000 kWp (kilowatt peak). In this way, we are reducing our ecological footprint by more than 1,700 metric tons of CO2.In 2017, only two additionalsolar plants (with a total of 16 kW) were installed.
With the additional expansion, we are approaching our goal to equip a total of 600 sites with solar photovoltaic systems in the coming years. In 2017, we drew up a concept specifying how we can render more roof space usable for photovoltaic systems. Our internal energy service provider, Power & Air Solutions, is responsible for installing the systems.
More green energy at European national companies
In our European national companies, we want to increase the share of renewable energy in overall energy consumption to a level of at least 10 percent above that of the respective national energy mix on an annual basis. In the reporting period, we were able to further increase the share of renewable energy in the European national companies. On average, the share of renewable energy was registered over 11 percentage points above the respective country mix*. To this end the national companies can also purchase renewable energy certificates (proof of origin) if needed.
Our national companies in Greece (OTE), Hungary, Albania, Austria and in the Netherlands are already pioneers in this field and cover 100 percent of their electricity needs with renewable energies. T-Mobile US is planning on procuring its electricity entirely from renewables by 2021 - predominantly from wind power.
We are making the share of renewable energy transparent on a national company level:
* In the calculation of the share of renewable energy in electricity procurement, the provider mix, the residual mix or the country mix is used as available, according to the IEA factor (in this order). The share of renewable energy in the residual mix is typically lower than the share in the country mix. For Germany, the EEG surcharge paid is taken into account when calculating the share of renewable energy.
