In order to achieve our ambitious climate protection goals, we use resource-conserving information and communications technology in the products and services we offer to our customers. What is more, we are also systematically optimizing our operational processes and our network infrastructure in terms of climate protection. We work to reduce the relative energy consumption generated by our business activities in relation to revenues. We have been using the Energy Consumption CR key performance indicator (CR KPI) and the CO2 Emissions CR KPI to measure progress in this area since 2010. A detailed description of the CR KPIs can be found in the "Strategy and management" section.

Certificates for 3,000 GWh of renewable energy acquired.

Telekom in Germany has been using renewable energy sources to cover 100 percent of its electricity needs via RECS-certified (Renewable Energy Certificates System) Scandinavian water and wind power plants. We purchased certificates for roughly 3,000 GWh in 2011. These certificates are reviewed and reissued annually by the technical services provider TÜV-SÜD.

We test other technological options for generating renewable energy in various pilot projects. For example, we installed another photovoltaic system in Bonn to test the use of solar energy for mobile base stations during the reporting period. The results should be available in 2012. We also conducted a study to research conditions such as feed-in rates for electricity supplied to the grid and local grant requirements for using power from renewable energy sources at 14 international subsidiaries. This data will be used in the international subsidiaries' sustainability programs.

PASM develops Telekom 2020 energy concept.

Experts from Power and Air Condition Solution Management GmbH (PASM) reviewed energy use and procurement at Telekom for efficiency, environmental friendliness and supply reliability in the reporting period. The company looked at different factors and potential components of energy management from the all-IP  network's energy consumption patterns and the green power privilege under the German Renewable Energy Sources Act (EEG) to introducing a Group-wide smart grid. The review also took external factors such as legal requirements and technological developments into consideration. The initial results were presented in the Telekom 2020 Energy Concept in August 2011. We will be discussing the different energy concepts and their possible impacts on Telekom's CR strategy with the responsible corporate units in 2012.

Based on the results of the review, PASM and Deutsche Telekom teamed up with Deutsche Funkturm, Deutsche Telekom Technik GmbH and Group Facility Management to develop comprehensive measures to significantly reduce energy consumption from 2012 to 2014. These include:

  • Using energy-efficient technologies in the network infrastructure
  • Using highly efficient fresh air cooling systems for smaller network nodes
  • Using waste heat generated by telecommunications technology to heat buildings
  • Generating electricity, heat and cooling locally
  • Using low-energy lighting in offices

The energy concept indicates that it may take several years to successfully implement these measures. Generating electricity, cooling and heat, using waste heat generated by technical systems to heat buildings and increasing the energy efficiency of our equipment will positively impact costs and the environment. We will be installing additional systems to locally generate electricity and heat as early as 2012. However, the review also indicated that the direct procurement of energy from renewable sources as defined in the German Renewable Energy Sources Act is not possible on a cost-efficient scale under current legal conditions. That is why we may initially be targeting higher-grade certifications instead of the current RECS certificates.

PASM's managing board designated an energy manager in 2011 and approved targets, measures and implementation plans for the company's energy strategy. They also introduced an energy management system for the production area. PASM was certified in accordance with the DIN EN 16001 energy standard in November 2011. As in the previous year, PASM was also recognized as an energy-efficient company pursuant to § 41 of the German Renewable Energy Sources Act by the German Federal Office of Economics and Export Control.

Energy-efficient facility management.

Effective facility management is a key component in Telekom's efforts to achieve its ambitious climate protection goals. That is why we conduct an energy-related inspection of heating and ventilation systems as part of all facility renovation work and are constantly working to make our facility management practices even more energy- efficient. We increased the energy efficiency of our facilities during the reporting period by conducting various measures, including:

Energy analysis: We recorded the energy consumption of our largest buildings and conducted additional microanalyses for three properties on the basis of different consumption measurements for areas such as heat, water and electricity. We then came up with specific recommendations for further action. The purpose of these activities is to evaluate the facilities in terms of energy efficiency in accordance with the new energy performance certificate in Germany. We are planning to assess six additional buildings in 2012. We have also begun including investments for energy savings measures at buildings in our budget.

Efficiency KPI: Power and Air Condition Solution Management (PASM) developed an efficiency KPI for assessing energy consumption at office buildings. We commissioned the on-site analysis of ten properties based on the results. The analyses included heating and cooling equipment, lighting, ventilation systems and tools. The analyses also looked at how meters could be retrofitted to improve invoicing accuracy and positively influence user behavior. The microanalyses indicated savings potential for energy consumption of up to 15 percent. We have begun implementing the measures recommended by the analyses.

Introduction of LED lighting: We began switching over to LED lighting for general areas such as stairwells, corridors and basements at several office buildings in December 2011. We are planning to conduct these measures at other sites as well. In 2011 we also initiated the LED@Office project with the goal of equipping all Telekom offices in Germany with LED lighting. We already made the switch in some offices and assessed our experiences in cooperation with Group Facility Management, Procurement, Telekom Deutschland and T-Systems. We then commissioned the technical services provider TÜV Rheinland to analyze the results and switched over to LED lighting at other test sites. We plan to evaluate operations at those sites in late 2012.

In addition to six further microanalyses in 2012, we are also planning to conduct more waste heat projects. For example, we plan to generate heat from central cooling equipment and using large heat pump systems located in ventilation ducts. This will enable us to tap the energy used to operate the Telekom networks to heat our offices. A similar project in Frankfurt/Main is currently in the bid phase.

Croatia: Energy management at the company level.

T-HT Hrvatski Telekom is aiming for clear synergies and cost effects with the launch of an energy efficiency project at the company level that merges existing individual initiatives. The project was launched in June 2011. In total, more than 30 projects with excellent savings potentials have been identified. This includes more efficient use of cooling and heating systems as well as a migration to renewable energy resources. Today, 219 of the 1,684 vehicles in T-HT Hrvatski Telekom's fleet are operated with liquefied petroleum gas (LPG). To motivate its employees to engage in more efficient driving behavior in this vehicle class, the company held an internal ecological driving contest in 2011.

Savings in the Greek fixed and mobile communications segment.

The Greek subsidiary OTE completed the evaluation of its second largest and most energy-intensive administration building in 2011 as part of its program launched in 2008 to calculate the carbon footprint of buildings. An annual savings potential of around 2,500 MWh was calculated for the entire building—requiring an investment of EUR 700,000.

In addition, the company is planning to increase the highest permissible temperature in office buildings by 2°C to 26°C. This measure would enable some 750 MWh of power for air conditioning to be saved every year.

OTE also intends to improve its carbon footprint by switching to alternative energy production. An application was submitted in October 2011 to mount a 350 kW photovoltaic system on the roofs of commercial buildings in Attica. In April 2011, a program for evaluating the potential of wind energy, including a feasibility study for three wind turbines, was started in Crete.

Efficiency programs in mobile communications segment a success.
Cosmote, OTE's mobile communications arm, also achieved high savings potentials through energy efficiency measures during the reporting period. These include the installation of systems for outdoor cooling or wind turbines or the use of energy-efficient communications technology. Overall, the measures in 2011 meant that some 3,700 metric tons of CO2 (i.e., 2.8 percent of the previous total emission figures) were avoided. Furthermore, the energy consumption at the base stations was decreased by 3.7 percent.

In 2011, Cosmote covered 1.1 percent of its energy consumption with renewable energy sources.

Hungary: 51 GWh of energy from renewable sources.

Hungary's Magyar Telekom is increasingly using power from renewable resources for operating its facilities. In the 5-year strategy, the goal is to purchase 46 GWh of green energy by 2015. Already in 2011, 51GWh were achieved. This accounts for almost 23% of the total volume used by Magyar Telekom Plc.

In order to achieve its climate protection goals, Magyar Telekom also launched a research and development project during the reporting period at a base station in Iszkahegy. The plan is to power the station with wind and solar energy. The technical equipment should be installed by late March 2012.The generation of renewable energy should be continuously monitored and analyzed for potential of a possible extension.

CR Report from the previous year 

Free cooling in 40 branch offices at Slovak Telekom.

Slovak Telekom continued its installation (begun in 2008) of systems for the use of low external temperatures (free cooling), and outfitted 40 branch offices accordingly in 2011. Today, a total of 110 branch offices in Slovakia are using this state-of-the-art technology, thereby decreasing the energy consumption of their heating and cooling systems by 20 percent. Depending on the size of the branch office, this amounts to between 6 and 15 MWh per year. In addition, Slovak Telekom has been gradually replacing the environmentally harmful coolant chlordifluormethane in its air conditioning systems since 2009. 63 systems were retrofitted in 2011. The switch-over is scheduled for completion in 2014.

Higher energy efficiency saves 2 GWh in Poland.

The Polish subsidiary PTC took various measures to decrease its relative energy consumption by 2 GWh at its branch offices during the reporting period. One example is the use of energy-efficient air conditioning systems and dynamic voltage regulators that adapt the power supply voltage to current demand. Innovative meter reading technologies for electricity meters in turn reduce the number of trips made to the base station.

British subsidiaries support climate goals.

40 percent fewer CO2 emissions compared to the time period between 1995 and 2020—this ambitious reduction goal specified by Telekom in Germany has also been adopted by T-Systems UK. In order to achieve this, the subsidiary will set specific reduction goals for its local units for 2012. These measures will be accompanied by comprehensive employee information.

The company conducted several measures for reducing CO2 emissions during the reporting period. Two projects were launched in June to provide fresh-air cooling at the data centers in combination with integrated use of waste heat to drastically reduce energy consumption. The permissible temperature at the data centers was increased to save on air conditioning use. Both measures are still being fine-tuned, and the actual reduction results are not yet available. More energy savings were achieved by switching the lighting system at 30 locations over to LED lighting equipped with motion sensors.

Initial measurements indicate that the consumption was reduced by 75 percent, from 465.47 to 116.61 kWh. Due to the high costs involved, LED lighting will only be installed in new buildings or when renovations are being carried out.
