3. ICAO Environmental Goals
Mitigate
Implement
Limit or reduce the number of people affected by significant aircraft noise
Limit or reduce the impact of aviation GHG emissions on global climate
Limit or reduce the impact of aviation emissions on local air quality
Quantify
Minimize the adverse effect of global civil aviation on the environment

7. Measuring Fuel Efficiency Changes
ICAO CO2 Reporting and Analysis System (ICORAS)
Requested by A37
Integrates and verifies measured fuel consumption and RTK data from States with modelled results

9. Conclusions
Noise, LAQ, CO2 emissions expected to grow slower than demand.
Achievement of goals requires action beyond that evaluated.
This is challenging, but not impossible.
Important to find solution that will allow aviation to grow sustainably and continue delivering benefits.
