Introduction Other than the UPA, no formal decisions on expansion have Because of an expected increase in air travels, Swedavia is currently been made. currently planning an expansion of Stockholm-Arlanda Airport. Their aim is to have a capacity of 70 million yearly passengers by Economic growth, along with other external factors, have 2067, which is around three times the amount of passenger today. contributed to Swedavia’s realisation that the earlier Masterplan If this vision is to become reality, it is important to assess the from 2014 is outdated. Instead, a new (Draft) Masterplan has been impacts, effects and consequences of the expansion on the developed, which was presented in 2017. The Draft Masterplan environment. Consequently, this environmental impact presents strategies for Arlanda to become the leading assessment (EIA) aims to do so. It will focus on the two Scandinavian airport and regional transport node. alternatives for terminal expansion presented by Swedavia in Arlanda Airport is classified as a national interest and also their Draft Masterplan from 2017. Other than these two includes a relatively large area of land outside the central, alternatives, the EIA will also look at a zero alternative that operational area. As a national interest, Arlanda is protected explains what will happen to the environment if the project is not against change that would prevent or diminish the airport’s carried out. Lastly, we will present our recommendation for which operations. Future expansion will most likely require that the alternative is preferable in regard to the environment. boundaries for the national interest area are moved. Since

Arlanda officially opened in 1962, several expansions have taken Background place, and today the airport has four terminals: 2, 3, 4 and 5. Prior Air travel at Arlanda has increased with 40 per cent over the past to UPA, Arlanda had 350 000 m2 of terminal area. For a capacity six years, with 23 million passengers passing through the airport of 70 million yearly passengers, Swedavia has calculated that this in 2015. Because of this, a first step to expand Arlanda began in area will need to be doubled. The two alternatives proposed for 2014. This first step is a development programme called future expansion in the Draft Masterplan include developing the Utvecklingsprogram Arlanda (UPA), and it is expected to last until existing terminal structure (Alternative Central) or constructing a 2023, creating a total capacity of 35 million yearly passengers. new terminal building in an unexploited area (Alternative North).

Three additional alternatives have already been identified and
