MJB&A conducted a comparative analysis of energy use and exhaust emissions of carbon dioxide,
nitrogen oxides, and particulate matter from twelve different transportation modes for the
American Bus Association. The analysis compared the performance of the highway
motor coach industry to the use of personal automobiles, air travel, and traditional "public"
transportation modes such as bus and rail. For each mode, energy use and emissions
were expressed in terms of units per passenger mile. This study primarily used
publicly available data from the U.S. Department of Transportation, including data reported
to the National Transit Database. Given that coach buses are generally more energy
efficient than many other transportation modes MJB&A also evaluated the potential for
capturing GHG offsets from typical coach bus operations. This included the
development of a template model to determine net carbon dioxide reductions from new coach
services that displace trips in personal autos.
