DNA signs up to Society's Commitment to Sustainable Development

DNA has signed up to Society’s Commitment to Sustainable Development, under which we undertake to reduce the climate impacts of our operations. As a Finnish telecommunications group, we want to assume responsibility for reducing emissions and improving energy efficiency.

Since 2012, DNA has reduced its greenhouse gas emissions in a number of ways. The results show that a large part of the greenhouse gas emissions originate in production, i.e. the power consumption of DNA’s radio network and transfer equipment and the maintenance of related equipment facilities.

Ever-increasing demand for high-speed connections, the resulting network expansion, and the explosive growth in mobile data pose challenges to the energy consumption of the radio network. In 2015, for example, the volume of data transmission in DNA’s 4G network tripled.

The constantly growing data transmission requires more equipment, which will, in turn, lead to an increase in energy consumption. On the other hand, the 4G network will reduce the energy consumption in proportion to data volumes through the outstanding technical performance of LTE. At present, as much as 67 per cent of all mobile data is transmitted in the 4G network. However, improving the energy efficiency of the radio network is still one of the key factors, when DNA is striving to reduce its emissions.

The various players signing up to Society’s Commitment to Sustainable Development, an initiative falling under the responsibility of the Prime Minister’s Office, undertake to promote sustainable development in their work and operations. Society’s Commitment to Sustainable Development is part of Finland’s efforts to implement the UN’s Sustainable Development Goals and is also a long-term objective for the future of Finland. 

DNA's climate targets

1. While the expansion of DNA’s networks continues, we will reduce our total emissions by 15 per cent by 2020 (from the level reported in 2014).

Key actions:

  • Buying emission-free renewable energy

  • Improving the energy efficiency of the radio network

  • Improving the energy efficiency of data centres and office premises

Indicator: Total emissions of the DNA Group, tCO2

2. By 2020, we will improve the energy-efficiency of our radio network and reduce the emissions from the radio network in proportion to our data volumes by 80 per cent (from the level reported in 2014).

Key actions:

  • Investing in energy efficiency functionalities in the radio network and in energy-efficient radio units

  • Investing in an energy-efficient 4G LTE network

  • Completing the modernisation of base stations

  • Relocating radio units from base station equipment shelters to masts during network upgrades to omit the need for mechanical cooling

Indicator: Emissions from the radio network in proportion to the data volumes of the network (tCO2/terabyte).
