Civil aviation’s environmental impact primarily comprises emissions from consumption of non-renewable fuels and noise. Aircraft operations often account for more than 95% of the total environmental impact of an airline.
SAS’ environmental responsibility is to comply with relevant legislation as well as to ensure as low as possible total long and short term emissions and other environmental impact.
“Polluter pays” principle
SAS fully endorses the “polluter pays” principle and is prepared to take responsibility for its share. This assumes that any charges imposed on it are based on scientific findings and that the total climate impact of competing modes of transport is taken into consideration.
CO2 vs. nitrogen oxides
To date, the climate impact of air transport has focused on CO2 emissions. However the focus is shifting to also include other climate effects, primarily nitrogen oxides and water vapor. SAS and the airline industry recommend the ECAC’s model of differentiated landing fees based on nitrogen oxide emissions.
Biological diversity is affected by airline operations in different ways. Flight in itself affects biological diversity to a limited extent through emissions, primarily of nitrogen oxides. Other aspects include facilities and the use of airports, which, depending on geographic location and by utilizing large areas, can affect water, flora, fauna and nearby residents.
Airlines purchase services from airports with private or public investors. Every new construction or other change in ground use requires authorization from local authorities. Biological diversity is normally an approval aspect.
Biodiversity, airport concessions and other environmental aspects regarding airport operations are reported in each respective airport’s own sustainability reports.
Aviation industry moving towards zero emissions
SAS fully supports IATA’s vision that, by 2050, it will be possible to fly commercially without climate impact. This vision is to be realized through a combination of new technology, more efficient air traffic management, new fuels and coordinated actions to improve the infrastructure and the conditions under which air transport operates.
To achieve this vision, IATA and other areas of the airline industry have agreed on a joint target, which will subsequently be adopted by the entire airline industry and is now set to be further developed by ICAO:
• Improvement of fuel efficiency by an average of 1.5% annually until 2020
• Carbon-neutral growth from 2020
• 50% reduction in greenhouse CO2 emissions by 2050, compared with 2005 levels
SAS Environmental Goals 2020
The environment goals up to 2020 will lay the foundation for ensuring that SAS operations will be sustainable in the long-term. The work on the necessary measures are a natural, integrated part of the SAS Environmental Programs conducted within the SAS environmental management system certified according to ISO 14001. The deterioration in market conditions has not affected SAS’ goals.
The goals are as follows.
- Reduce flight emissions by 20% in 2020 compared with 2010.
- Reduce noise emissions on take-off by 15% in 2020 compared with 2010.
- Regularly use renewable jet fuel in 2020.
