Every element has a direct impact on fuel burn & CO2 emissions.

Optimum altitude

Reach optimum altitude ASAP

However, speed limits on climb out…

Significant savings if clean airspeed departure

Clean Airspeed Departures

About 200-1600 kg fuel savings

Maintain en route flight at optimum altitude

Optimum altitude varies according to weight

Enhancing capacity / reducing emissions

Procedural / time separation

Utilizing technology

1. Position broadcast by the aircraft (ADS-C) and Navigation accuracy

2. Direct controller / pilot communication (CPDLC)

3. Technology / available today

Reducing delays & optimum altitudes

Equates to CO2 - reductions

Infrastructure enhancements

Goal: Continuous descent for arrival

Fuel Savings on Arrivals

10% less fuel 40% less noise Saves 50-200 kg fuel

150 - 640kg less CO2

Conclusion Infrastructure ATM enhancement is critical

Technology on aircraft Reduced reliance on ground systems

Airlines investing: Reduce emissions Plan for ASPAC (based on ICAO GPIs) Accelerate progress from States
