ACRP Web-Only Document 13: Alternative Fuels as a Means to Reduce PM2.5 Emissions at Airports, published in 2012, explored the potential benefits of using alternative fuels for aircraft and ground service equipment to reduce PM2.5 emissions. This research indicated substantial benefits from using alternative jet fuels in aircraft and recommended further research in that area. The understanding of potential benefits of alternative jet fuels continues to increase, and new data and analytical techniques have become available.
There is a desire by airports, airlines, and air quality regulators to further explore and understand changes in emissions (e.g., hazardous air pollutants (HAP), NOx, SOx, PM2.5) through the use of ASTM-certified alternative jet fuels.
Research is needed to build on the findings presented in ACRP Web-Only Document 13 and other related research to help airport industry practitioners estimate potential emissions reductions benefits from using alternative jet fuels, with the goal of promoting their increased use.
The objective of this research is to develop a method to help airport industry practitioners estimate potential PM2.5, NOx, SOx, and HAP emissions reductions by the use of ASTM-certified alternative jet fuels. The method should, at a minimum:
- Allow users to understand the potential impacts of the use of ASTM-certified alternative jet fuels as it relates to PM2.5, NOx, SOx, and HAP emissions;
- Address landing-takeoff (LTO), cruise, and full-flight emissions; and
- Be compatible with the AEDT model for quantification of emissions and air quality simulation tools (e.g., CMAQ) to model ambient concentrations of PM2.5 and ozone.
