Shaping its business processes, offices, products and services around the principles of sustainability in order to leave a better world for future generations, Türk Telekom views the active participation of employees, their families, suppliers and customers in this process as an integral part of its strategy.

Sustainability in Business Processes 

Well aware of the social and environmental impact of its high level of energy consumption, Türk Telekom attach importance to undertake investments in energy efficiency and renewable energy in order to use natural resources efficiently, to extend the use of renewables, and to minimize adverse impacts on nature.

By using solar and wind energy, the company is able to make carbon savings.

Similarly, with central transformation/FiberkenTT project, central with low energy efficiency are replaced with next-generation centrals and outdoor equipment with high-energy efficiency.

Carbon Disclosure Project 

As a leading ICT company, Türk Telekom provides products and services which support the low-carbon economy, by spending efforts on decreasing its GHG emissions, as well as supporting different sectors with low-carbon product and service solutions. GHG management and combating climate change is one of the major issues for the company and those are already embedded into the company's overall strategy.

Türk Telekom became the first Turkish telecommunication company to report to CDP (Carbon Disclosure Project) in 2010. In 2011, Türk Telekom was awarded as one of the two best reporting companies in terms of methodology and transparency, among the companies that made CDP reporting within BIST100, while in 2012, Türk Telekom was among the top 5 companies in this issue.

As Türk Telekom, in 2016, we began to disclose to the Carbon Disclosure Project (CDP), which reflects our ability to combat climate change, which we had halted during to structural changes and corporate mergers. Our goal at this stage as Turkey's leading technology and communication company is to be an example in our own sector, and a facilitator to other sectors in combatting climate change.

In our 2016 disclosure to the CDP, we reduced our carbon emissions by 16% when compared with the base year of 2015 with efficiency and reduction projects that we implemented. Likewise, our total carbon emissions in Scope 1 and 2 have declined by 6.5% compared to the base year of 2015.

We are trying to improve our climate change performance each year in parallel with the new economic order to be established by the Paris Treaty and with the Sustainable Development Goals adopted by the United Nations in 2015. In this context, we have released 44 tons of carbon emissions for each million TL added value, and our goal is to reduce this amount every year.

Within the scope of the CDP, we share Scope 1-2 and 3 emissions with our investors.

Sustainability in Offices 

In the context of sustainability in offices, building/hall optimization projects provide significant savings in space savings and consequently in energy consumption for cooling. In addition, with the use of energy saving bulbs, heat insulation and jacketing, public transportation, building automation, an environmentally friendly vehicle fleet, paper recycling, electronic document and documentation system (EDITT), central printing systems, e-learning, telepresence and video conference usage, recycling, savings and reducing carbon emissions are ensured.

Türk Telekom is taking various steps not only to control its own activities but also to raise awareness. The implementation of e-billing within the scope of environmental products also offers the benefit of a reduction in customer carbon footprint.

DX Air Conditioning Transformation project: Air conditioning systems have been replaced with new generation energy efficient conditioning systems. As a result of this transformation, operation costs and energy consumption levels have decreased.

Türk Telekom is running efficiency and reduction activities and investing in newer technologies which could enable reduction in GHG emissions due to our operations.

Türk Telekom Technology Center and Türk Telekom Esentepe Campus received the "LEED Gold Certificate"

  • The lighting fixtures in the project have been designed to provide over 90% more sunlight than the installed power and operate with presence sensors.
  • Within the scope of the project, environmentally friendly refrigerants which do not damage the ozone layer have been preferred in the cooling systems.
  • For all building materials used in the building, those with sustainable and environmentally friendly properties have been preferred.
  • In the project, recycling points per floor have been created.
  • At least 50% by weight of waste materials occurring during construction have been reused or sent to recycling.
  • Within the scope of the project, materials with more than 10% recycled content were used.
  • During the building's construction, local materials that have positive characteristics in terms of cost, transportation and environmentalism were used at a rate of over 20%.
  • In this context, building chemicals (paint, primer, adhesive, putty etc.) to be used in the building were selected from those with VOC (volatile organic harmful compound) ratios in accordance with international limits.
  • The fresh air rates given in the buildings have been kept above the ASHRAE 62.1 standard, with the building users expected to live in a healthy and comfortable environment.
  • Emphasis is placed on individual control in heating and lighting systems, aiming to increase both energy savings and interior life quality
  • When the interior design of the building is made, care has been taken for residents of the building to be able to easily see the outside from where they are located.
