How does renewing the fleet decrease carbon dioxide emissions?
The age of an aircraft tells us a lot about its consumption and emissions. Each new generation of jet aircraft use up to a quarter less fuel than the previous generation. The amount of carbon dioxide emissions decrease in the same proportion. Finnair aircraft today consume a fourth less fuel than in 1999. Finnair’s European and domestic fleet has an average age of under three years. Finnair has been systematically renewing its fleet for years. The airline made the decision to install eco-efficient CFM56 engines on its Airbus A320 fleet ten years ago already. The new Embraer 170 and 190 aircraft also represent the newest 21st century technology and are very eco-efficient on those routes which only require a 76 or 100 seat aircraft. The next phase of fleet renewal is already in the plans when Finnair replaces its Boeing MD-11 fleet with new Airbus A330 aircraft by the end of March 2010. The new Airbus A330 releases 20 per cent less emissions than the MD-11. For the A340 this figure is 10
