EPA's mission and strategic goals encompass areas of aviation's environmental impact
The Clean Air Act (CAA) directs EPA to set and enforce national standards for "criteria pollutants"
Location of "non-attainment" areas for criteria pollutants as of September, 1998
EPA establishes emission standards for aircraft engines and FAA enforces these standards
Aircraft contribution to regional mobile source NOx emissions at selected US cities is estimated to increase
|
Aviation CO2 emissions are a significant source of GHGs
Worldwide aviation emissions are expected to grow, despite emission reduction technologies
The global climate impact from subsonic aircraft extends beyond that from CO2 alone
EPA actively participates, with FAA and NASA, in ICAO/CAEP's technical working groups (WGs)
EPA and NASA exchange and coordinate on science, technology, and policy developments affecting aviation
NASA's activities are critical to the environmental sustainability of aviation
