Air Quality at Boston Logan

Measuring Emissions in and around the airport

Air emissions associated with operations at Boston Logan International Airport come from three primary sources:

  • Aircraft
  • Ground Service Equipment
  • Motor Vehicles

Additional sources include fuel storage, heating and cooling; however aircraft are the largest single source of emissions at Logan.

Aircraft emit four principal air pollutants: carbon monoxide, volatile organic compounds, oxides of nitrogen and particulate matter. The U.S. Clean Air Act, which was last amended in 1990, requires the Environmental Protection Agency (EPA) to establish air quality standards for outdoor (ambient) air to protect public health and the environment. Air quality at Boston Logan is governed by these standards as well as other federal and state regulations including the Massachusetts State Implementation Plan (SIP).

Massport is committed to the environment, particularly to reducing emissions generated by airport activity at Logan. View our green initiatives and achievements for more information on what we are doing to reach this goal.
