TRB’s Airport Cooperative Research Program (ACRP) Report 64: Handbook for Evaluating Emissions and Costs of APUs and Alternative Systems is designed to help airports evaluate alternatives to aircraft auxiliary power units (APUs).

The handbook addresses environmental impacts, costs, infrastructure and maintenance requirements, and funding options.

The printed version of the handbook includes a CD-ROM that contains software that can be used to help quantify emissions from APUs and alternative systems, while also providing quantitative analysis of the financial implications of implementing and operating the systems.

The CD-ROM is also available for download from TRB’s website as an ISO image. Links to the ISO image and instructions for burning a CD-ROM from an ISO image are provided below.
