Greenhouse gas emissions

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

Our climate initiative focuses on how to increase energy efficiency in offices and data centres, and how to reduce business travel. In 2015, Tieto's Scope 1 CO2 emissions decreased by 26%. Despite increased energy efficiency, the related Scope 2 CO2 emissions increased by 2% due to changes in calculation methods and emission factors. Scope 3 CO2 emissions decreased by 11%  due to reduced business travel. Total reported CO2 emissions decreased by 3% to 31 ktons CO2 (32).  

In 2015, base year emissions for Scope 2 were updated using three year average factors for all years. The resulting quality improvement is that the Scope 2 CO2 emissions follow the changes in related Scope 2 energy consumption and thus are more indicative of the effect of energy management on CO2 performance.

As a whole, approximately 70% (65%) of our reported CO2 emissions in 2015 derived from energy consumption in business operations. While travel represents only a small part of our purchases, it is still recognized as one of our key emission sources. In 2015, 32% (35%) of our reported CO2 emissions related to employee travel. 

To reduce greenhouse gas emissions caused by business operations, we have set energy consumption targets, as well as travel cost targets. Activities relating to energy consumption are presented in more detail in the Energy consumption text.  In 2015, travel spend was reduced by 0.7% (3.9% in 2014). Our goal was to reduce travel costs by 4.0% (4.3% in 2014). During the year, the businesses did concentrate more on putting effort on growing the business than cost savings which was somewhat not anticipated when the goal was set. Also the travel from India to Europe was increasing heavily due to the offshoring, which increased the travel costs. However the increase of total travel spend was avoided by closely monitoring the compliance to our Travel Rule and reporting to the Service Lines and Industry Groups to give a notification about the travel spend development.

Our Travel Rule requires a pre-approval step for employee travels, which helps to eliminate unnecessary travel. We also encourage employees to use our 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 functionality to share digital content with others.
