EIA Topics

EIA shows that the third runway can be built and operated sustainably

The Environmental Impact Assessment (EIA) was submitted to the authorities by Vienna International Airport with the application for approval. Twenty teams of experts have written a total of thirty-nine opinions on topics such as aircraft noise, air pollution and ecology. Each opinion gives a detailed assessment of the impact that the construction of a third runway will have and also contains recommendations for reducing this impact.


A landscape management plan will be implemented to improve the biosphere and minimise the effect of human intervention during the project. It takes account of the natural surroundings and ensures that the environment and biotope will be protected during the construction of the third runway. The terrain will be modelled and plans for its cultivation drawn up (creation of natural habitats, guide systems for wild animals, etc.). Landscaping and environmental measures will be implemented on an area of around five million square metres. The wooded areas to be cleared during preparations for construction of the runway will be replaced by new plantings in a ratio of 1:3. This means that for every square metre of woodland cleared, three will be planted.

Air pollution

The construction of the third runway will not cause any appreciable increase in emissions. The additional pollution during the building phase will be minimal. In spite of the forecast increase in traffic by 2020 and 2025, the NOx, CO, SO2, benzene and PM10 emissions will be even lower than the 2003 levels on account of the stricter waste gas standards and reduced specific fuel consumption by the fleets.

Aircraft noise

Experts have made detailed forecasts in the Environmental Impact Assessment that show where there is likely to be more noise for the people living close to the airport and where there will be less. Additional noise in excess of 10 dB will occur only in uninhabited areas. The third runway will make it possible to manage take-offs and landings more efficiently than with the current system of two intersecting runways.
