Emissions Reduction Strategies
Improving Air Quality at Boston Logan
Massport is committed to being a good neighbor and reducing the impact of airport operations on the environment. As such, we have implemented a number of emission reduction strategies at Boston Logan including the voluntary Air Quality Initiative (AQI) implemented in 2001 with the goal of maintaining levels of nitrogen dioxide emissions associated with the airport at or below the levels from 1999.
Nitrogen dioxide emissions at Boston Logan have decreased by 28% since 1999. Between 1999 and 2008, the greatest reductions of nitrogen dioxide emissions were associated with on-airport motor vehicles (62%), ground service equipment (42%), and aircraft (22%).
Air Quality Initiative
This 15-year program has four primary commitments:
• Expand on existing initiatives at Logan. View the Air Quality Initiative Inventory Tracking of Nitrogen Dioxide Emissions for information on programs in place at place at Logan Airport when the Air Quality Initiative was developed.
• Retire emissions credits giving priority to mobile sources in order to maintain nitrogen dioxide emissions at or below 1999 levels.
Massport updates the Logan Airport inventory of nitrogen dioxide emissions annually to reflect new information and changing conditions associated with the Airport’s operations. In 2008, it was not necessary to purchase and retire mobile source emission credits to maintain nitrogen dioxide emissions at or below 1999 levels. Based on current projections, no credits will need to be purchased through the AQI period of 2015.
• Report the status and progress in Massport’s Environmental Data Report (EDR) and Environmental Status and Planning Report (ESPR).
• Continue working to decrease air emissions from aviation sources at both a national and international level.
Massport is a member of and participates in a number of organizations which address aviation-related environmental issues, including air quality. These include serving on technical review committees for the Transportation Research Board (TRB) and the Airport Cooperative Research Program (ACRP), research projects and environmental committees of the American Association of Airport Executives (AAAE), and Airports Council International (ACI).
Working with Airline Partners
As part of our efforts to reduce emissions associated with aircraft taxiing, Massport did outreach to each of Logan’s airlines encouraging voluntary use of single engine taxiing, consistent with safety, pilot judgment, and federal law. Massport is coordinating with the FAA Office of Environment and Energy and Massachusetts Institute of Technology (MIT) to demonstrate possible surface traffic management strategies to reduce aircraft emissions and fuel burn on the airport surface. A critical part of this research involved input from Logan Airport pilots with regard to single engine taxi procedures.
