Greenhouse gas emissions
Tieto continuously examines ways to reduce the greenhouse gas emissions of its activities. Emissions are mainly generated by indirect energy consumption in data centres and offices as well as by employee travel. Tieto’s goal is to reduce global CO2 emissions of Tieto's indirect energy consumption by 50% by 2020.
Tieto's aim is to minimize the company's environmental impact throughout its value chain. Tieto supports the precautionary approach to environmental challenges, and applies the principles of continuous improvement. Tieto's environmental targets focus on increasing energy efficiency in offices and data centres as well as reducing CO2 impact of business travel.
Highlights of the year 2017 include the decision to shift all Tieto´s data centres in the Nordics to the use of green electricity, which contributes to the 2020 CO2 reduction targets significantly. In 2017 the indirect market based CO2 emissions from energy consumption decreased by 44 per cent.
Tieto’s intelligent head office was awarded the first in Finland with the highest Platinum certification for Leadership in Energy and Environmental Design (LEED).In addition, a sustainable office concept was created for Tieto´s head office in Espoo, Finland. Tieto has added roughly 6 000 sensors in the office to monitor the environment in real-time. One work desk is shared with 1.7 employees, resulting in a high usage rate of the office’s multifunctional space. Energy efficiency measures have been implemented, including optimizing heat and ventilation settings and installing hundreds of LED-lamps and occupancy sensors. Remote building automation control systems ensure continuous monitoring of the system. In addition, the building runs on electricity provided by wind power and the cooling system utilizes sea water. Roughly 40 per cent of the furniture is reused and all carpet material meets the highest indoor air quality requirements. Also energy efficient ICT equipment, environmentally solid new furniture and cleaning processes are in place.
During the year, the total reported location based CO2 emissions decreased by 4% to 28.6 ktons CO2 (29.9). Scope 1 CO2 emissions, generated by diesel consumption in data centres, increased by 5% to 117 tons CO2 (112). At the same time, our Scope 2 CO2 emissions generated by electricity consumption, cooling and heating slightly decreased by 85 tons CO2 reaching a level of 18.9 ktons CO2 (19.0). Scope 3 CO2 emissions decreased by 12% to 10 ktons CO2 (11) due to reduced business travel during the year.
The total reported market based CO2 emissions decreased significantly by 34% to 24 ktons CO2 (36). Market based scope 2 emissions decreased from 25 to 14 ktons CO2, representing a decrease of 44%.

As a whole, approximately 60% (62%) of reported CO2 emissions in 2017 derived from energy consumption in business operations. While business travel represents only a small part of the company’spurchases, it is still recognized as one of the key emission sources. In 2017, 40% (38%) of our reported CO2 emissions related to employee travel.
To reduce greenhouse gas emissions caused by business operations, Tieto has set energy consumption targets, as well as travel cost targets. The annual goal is to reduce indirect energy consumption in operations by 3.5% on the group level. In 2017, the indirect energy consumption decreased by 4% (4%) compared to the previous year, reaching 115 326 (120 618) MWh. Regarding travel costs, Tieto’s goal in 2017 was to keep travel costs flat. However, during the year travel costs decreased by 6% (+6 %), which indicates a change in employee travel habits with fewer trips, but longer stays. Additionally, there was a downhill trend in flight C02 emissions and own car usage. Tieto is constantly trying to find new and innovative ways to support smart travel and reduce the environmental impact of business commuting.
Tieto’s Travel Rule encourages eliminating unnecessary travel. The company also encourages employees to use internal online conferencing and various digital collaboration platforms.
Tieto's Environmental Rule defines the company's approach to managingTieto environmental impact. Tieto´s environmental management system (EMS) is ISO 14001 certified. In line with this rule, Tieto strives to reduce direct and indirect energy consumption in offices and data centres through energy-efficient measures and relocating to BREEAM or LEED certified buildings when upgrading facilities. In 2017 54% of Tieto employees were located in environmentally certified office buildings.
The amount of data transferred and stored is becoming increasingly immense, creating a growing demand for modern, secure and sustainable data centre environments. In its data centers, Tieto works continuously to improve energy efficiency in its operations, e.g. by optimizing cooling capacity, utilizing intelligent airflow management and deploying low energy computing solutions. Tieto also recycles the excess heat generated by its data centres back to society. Tieto has been recognized for its new-generation data centre in Espoo, Finland, where the excess heat is used in the local district heating network. In Stockholm, a similar solution is used to enable warming the facilities and thenearby housing area. Meanwhile, the data centre in Norway - located deep inside a mountain in Stavanger - is run with renewable energy and cooled by cold water from the adjacent fjord.
In 2017 the recycled heat energy from data centres was equal to roughly the annual energy consumption of 800 detached houses.
