Greenhouse gas emissions

Tieto continuously examine ways to reduce the greenhouse gas emissions of our activities. Emissions are mainly generated by indirect energy consumption in data centres and offices and by employee travel.

Tieto’s climate initiative focuses on how to increase energy efficiency in offices and data centres, and how to reduce business travel. The reporting of CO2 emissions caused by indirect energy consumption has been expanded to cover both location and market based CO2 emissions 2015-2016.

During 2016, total reported location based CO2 emissions decreased by 4% to 28 ktons CO2 (29). Scope 1 CO2 emissions, generated by diesel consumption in data centres, increased by 12% to 0.1 ktons CO2 (0.1).  At the same time, Scope 2 CO2 emissions generated by electricity consumption, cooling and heating, decreased by 11% from 20 to 17 ktons CO2. The Scope 2 calculations include energy fed back to district heating. Scope 3 CO2 emissions increased by 12% to 11 ktons CO2 (10) due to increased business travel during 2016.

Total reported market based CO2 emissions also decreased by 4% to 34 ktons CO2 (35). Market based Scope 2 emissions decreased from 26 to 23 ktons CO2, also representing a decrease of 11%.

As a whole, approximately 62% (70%) of reported CO2 emissions in 2016 derived from energy consumption in business operations. While business travel represents only a small part of the company’s purchases, it is still recognized as one of the key emission sources. In 2016, 38% (32%) 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. Activities related to energy consumption are presented in more detail in the Energy consumption text. Regarding travel costs, Tieto’s goal was to keep travel costs flat in 2016. However, during the year travel costs increased by 6% (0.7%), mainly due to the increased number of employees, and increased business travel related to the introduction of a new corporate strategy and reorganization in 2016.

Tieto’s Travel Rule requires a pre-approval step for employee travels, which helps to eliminate unnecessary travel. The company also encourages employees to use internal online conferencing options. These consist of a social and commercial media inspired workplace with digital communication and collaboration tools, such as integrated teleconferences, video conferences, chat, and functionalities to share digital content with others.
