Sustainable IT

We are committed to developing enterprises and society with innovative IT solutions. We strongly believe that IT has the potential to support sustainable development from economical, environmental and social perspectives.

At Tieto, sustainable IT is an umbrella concept, which embraces all of our work and IT solutions. It can sometimes be called green IT, which is a casual term to describe the manufacturing, use and disposal of IT in a way that minimizes the environmental impact over the lifecycle. With sustainable IT, we mean concepts such as cloud, big data and green technologies used in data centres, such as virtualization and energy re-use, which all have a positive sustainability impact for our customers and ourselves.

The positive impacts of IT span over many sustainability areas, which are often interlinked. Mobile welfare solutions are one such example, which might lead to increased efficiency as well as reduced greenhouse gas emissions through less travel or less use of paper. At the same time, IT can temporarily lead to negative sustainability impacts, such as increased energy consumption, if not handled. However, with a holistic approach, where the risks and opportunities are all addressed properly, we are convinced the long-term impacts of IT overall lead to improved economical, social as well as environmental wellbeing. 

The cloud is one example where the positive sustainability impacts span over economical, social as well as environmental aspects. With payments based on actual server usage, cost-efficiency in production of IT services can be achieved. At the same time, as services can be accessed anytime on any device, cloud services enable increased flexibility and wellbeing for the user of IT services. Furthermore, with services delivered from new-generation data centres, where energy efficiency is inbuilt in the solution, for instance through smart server utilization with modern virtualization technologies, or efficient cooling solutions, energy consumption can be reduced. Another example of an IT trend supporting sustainable development is Big Data. Here, large quantities of anonymized data made available through usage of online services and social media can be analyzed. Through these analyses, new research can be undertaken, enabling development of unique applications to solve critical business or social problems. 

We have measured the sustainability impacts of IT since 2010 by calculating the reduction of our customers’ greenhouse gas emissions through our digital transaction services and other identified services replacing paper. Based on our calculations, we helped reduce 217 594 tons (183 226 in 2013) of our customers' CO2 emissions in 2014 with these services1.

Avoided emissions

As part of our strategy implementation, we are currently proactively strengthening our service portfolio and competences in order to be a preferred digitalization partner to our customers, and to develop society at large. At the same time, we strive to mitigate the potential negative environmental impacts of IT. Our new-generation data centre in Espoo, Finland, is equipped with energy-efficient equipment and has a Power Usage Effectiveness number of 1.2–1.3 compared to 1.8–3.0 in traditional data centres. In addition, this data centre re-uses excess heat from servers and distributes it to private households and offices. Similar energy recycling solution is in use in Stockholm as well. Altogether, this energy recycling reduced CO2 emissions by 1 711.1 tons in 2014.
