Air, soil and water
The biggest source of carbon dioxide emissions at the airport are the aviation operations run by the different airlines. Aircraft emissions consist mostly of combustion gases. Other emissions are produced by ground transport to and from the airport. Altogether, fossil carbon dioxide emissions from Visby Airport constitute about 0.13% of Gotland’s total emissions. The Swedish aviation industry aims to be completely fossil-free by 2030 (domestic travel).
Surface water from aircraft parking stands and the runway is collected and reused. Residue from the urea used for runway anti-skid treatment is picked up in the flow of surface water, and the nitrogen contained in it fertilises a nearby golf course when it is watered. Reusing the airport’s surface water reduces the use of both groundwater and mineral fertiliser. Surplus glycol from the de-icing of aircraft is collected separately, excess water is removed, and the product is used as new de-icing fluid.
Firefighting exercises mainly use biogasol as a fuel and only water as an extinguishing agent. This prevents the emission of unburnt fuel into the atmosphere and the discharge of extinguishing agent residue into the soil.
Airport operations include the heating of properties. Heating is provided by heat pumps and green electricity. Swedavia’s own carbon dioxide emissions only from renewable forms of energy do not contribute to net carbon dioxide emissions in the atmosphere.
Sampling of run-off, groundwater and surface water is carried out in compliance with control programmes. Soil samples are also taken in conjunction with groundwork. There are residues of coal tar from older layers of asphalt.
The airport works very actively with residential planning. By changing approach and landing methods to the south of the airport and by holding meetings with pilots and air traffic controllers, efforts are made to limit noise exposure for residences and other operations that are sensitive to noise. The airport is located near the sea so only short flight paths over land are needed for current routes because most commercial traffic heads for the Swedish mainland.
Visby Airport has a rich variety of flora and fauna. Large parts of the airport area are managed as hay meadows, where many different species of plants and animals are found – a number of which are rare. Read more about biological diversity at Visby Airport.
