Emissions

Demand for air transportation, both for passenger and cargo service, has been increasing and airports are expanding to accommodate it. This growth is accompanied by an increase of emissions from aircraft, ground services equipment and vehicle traffic on and near airports. All this activity impacts the local air quality around airports and human health, and contributes to global climate change.

To help the industry comprehend and address concerns about emissions, ASCENT researchers are analyzing data and improving models to better understand the effect of aircraft emissions, creating and refining analysis techniques on airport–specific and global scales, and assessing how policy changes could affect emissions.
