7	Noise - Technological Solutions
8	Noise – Operational Solutions
9	Local Air Quality
10	Climate Change - Emissions
11	Climate Change - Contrails
12	Historical Fuel Consumption
13	Technology Solutions
14	Technology Solutions
15	Technology Solutions
16	Technology Solutions
17	Emissions – Operational Solutions Straighter Routing No holding patterns No hold-ups on ground More intermediate stops Flight refuelling Continuous Descent Approaches (CDAs)
18	Types of Taxes and Charges Problem charging on an international basis Regional Taxes/Charges Emissions Trading Hypothecation
19	Conclusions Noise & emissions have reduced by over 50% in last 20 years We need to go much further in the next 40 years Operations Less waiting on ground Less waiting in air Straighter routes Possible – more intermediate stops / flight refuelling
20	Conclusions Technology New designs for both airframe & engines New materials Possible – More efficient designs to fly slower Objective “Emissions no more in 2050 then in 2060, despite traffic growth”
