Aviation Environmental Issues
Community Noise LevelsCurtailing significant aircraft noise impacts around airports
Global ClimateUnderstanding and addressing the impact of aviation on Earth’s climate
Limiting or reducing impact of aviation on local air quality

Aviation Environmental Governance
United States FAA Office of Energy and EnvironmentPolicy and decision-making
ICAO CAEP—Emissions stringency, long-term goals, green house gases, influence future fleetFAA JPDO—airspace redesign, efficiencies in air traffic management, energy conservation
Regulatory complianceAirport authorities—environmental impact studies, respond to public inquiriesOperators and airframe manufacturers—airframe design constraints, operational fleet optimization

Why Integrate Noise and Emissions?
DOT 2004 R&D Annual Review
FAA 2005-2009 Flight Plan
FAA Joint Planning and Development Office—Next Generation Air Transportation System“Create new analytical tools to understand better the relationship between noise and emissions, the different types of emissions, and the costs and benefits of different policies and actions”
(http://www1.faa.gov/aboutfaa/flightplan.cfm)
“Develop better technologies and analytical tools to evaluate aircraft noise and emissions.”
“Ensure aviation remains a good neighbor.”
