Why Environmentally Friendly?
• Increasing Demand for Aviation 
Growing Impact on Environment
• Regulations: ACARE Report “European
Aeronautics – a Vision for 2020”
– Reduce fuel consumption and CO2 emissions by 50%
– To reduce NOX emissions by 80%
– Reduce perceived external noise by 50 per cent.
• Current Aircraft in Production
– Boeing 787, Airbus A350
