Environmental concerns during the renovation
Swedavia is at the international forefront when it comes to running climate-smart airports. Environmental issues have long had priority, and at Stockholm Arlanda we work in a number of different areas to reduce the environmental impact of aviation.
Stockholm Arlanda’s climate efforts are certified today at the highest level of a European programme that assesses how airports work to reduce their climate impact. One area in focus is reduced carbon dioxide emissions.
Always a focus on increased energy efficiency
As biofuels replace fossil fuels in the airport’s buildings and vehicles, other measures to increase energy efficiency are continuously being carried out. The airport also implements measures to ensure that as few people as possible are disturbed by aviation noise, water that runs off the airport runways is cleaned, glycol used to de-ice aircraft before take-off is collected, and all waste is sorted and recycled.
But what will it be like now in terms of noise and emissions given the large increase in passenger volume? There will certainly be more aircraft, but the number of aircraft movements – that is, take-offs and landings – will not increase as much as passenger volume. This is partly because airlines are getting better at filling planes and partly because the trend is toward airlines using larger aircraft that carry more passengers instead of adding more departures. The new generation of aircraft are also quieter and more fuel-efficient than older ones, which also helps to keep down increases in noise and emissions.
The environment and Stockholm Arlanda’s development plan projects
What are we doing at Stockholm Arlanda in terms of our development plans? The new buildings being constructed are subject to stringent environmental requirements. The buildings at the airport are heated by district heating produced from biofuel. Swedavia also buys green (renewable energy) certificates to prove that all electricity used at the airport is renewable.
These are Swedavia’s environmental requirements for buildings:
- The energy performance of buildings must be at least 25% better than current regulatory requirements for construction.
- Building materials must have a limited environmental impact and be easy to separate to facilitate recycling.
- Building materials must be approved by the Swedish building materials assessment programme
- Byggvarubedömningen, which assesses their environmental impact.
- Wood products must come from certified forests; no wood products from rainforests are allowed.
- Waste in the production of building materials must be prevented.
- Preventive measures are to be taken to minimise the impact on surface water and groundwater.
- Buildings must have water-saving fixtures to reduce water use.
Environmental certification further reduces environmental impact
Stockholm Arlanda’s aim is to environmentally certify a number of new buildings, which will further reduce their environmental impact. This will result in better indoor environments, more efficient energy use, reduced use of materials containing toxic substances, and reduced water use and waste. Certification entails a third party examining and approving the suggested rating.
