Abstract:The goal of this project was to develop a rigorous, flexible, and practical framework for estimating the emissions of freight transport operations. To meet this goal, the authors developed a software tool based on simple, yet defensible and reliable economic models of marginal emissions contributions from individual shipments. The initial focus is on trucking, but extensions for other freight modes are possible. The tool provides several practical advantages over currently available methods. In particular, it: is based on data that are commonly available from freight carriers; uses models of marginal emissions contributions instead of aggregate models; performs detailed analysis, by route, carrier, and business sector; provides error bounds, describing the precision of emissions estimates; and provides quantitative support for strategic shipping and supply-chain decisions. The tool is intended to be deployed as an online tool, and consulting services could be offered to users in order to support their use of the tool for emissions management.
