Stockholm Arlanda uses energy produced without any net carbon dioxide emissions
Some 16,000 people work in about 250 different companies at Stockholm Arlanda Airport. The airport uses as much energy as a small Swedish city. Today essentially all heating, electricity and cooling used by the airport are generated from renewable sources that do not produce any net carbon dioxide emissions. Naturally, an important part of the airport’s energy efforts is to continuously work to improve energy efficiency and thus reduce its environmental impact as well as costs.
The buildings at Stockholm Arlanda are warmed up with district heating based on biofuel. Swedavia also purchases “green electricity certificates” equivalent to its entire electricity consumption at the airport. These certificates guarantee electricity production from exclusively renewable sources, that is, wind, solar, hydropower and/or biofuels.
In the summer of 2009, Stockholm Arlanda also inaugurated the world’s largest energy storage unit – a so-called aquifer – in the nearby boulder ridge known as Brunkebergsåsen. The airport is both heated and cooled efficiently using the aquifer and without any environmental impact during the summer or winter.

During the period 2005-2012, Swedavia’s energy use at Stockholm Arlanda was reduced by almost a third. Measures such as more efficient and better controlled lighting indoors and outdoors contributed significantly to this reduction. Thus far, 10,000 energy-efficient LED diodes have replaced conventional light bulbs at the airport, cutting electricity consumption by as much as that used to heat 140 single-family homes with electricity.
Other examples of measures implemented are heat recycling in the terminals, more efficient ventilation and RPM-regulated electric motors.
The aquifer, which stores and reuses cooling and heating, can save as much energy as that used by 2,000 single-family homes.
Arlanda Energy awarded the Swedish Energy Prize
Swedavia Arlanda has worked systematically with energy issues for a number of years, and in 2009 the airport was awarded the Swedish Energy Prize for its business model, which takes a comprehensive approach to the airport’s energy issues. The Swedish Energy Prize is handed out by the technology consultant Sweco for technological ideas and innovations that are tested in real life and proven to save energy.
