Descripción
This paper compares the CO2 emissions from the use of personal vehicles to shared-use vehicles for
grocery shopping in Seattle, Washington. The research builds on existing literature by considering
the importance of modeling the logistical details of routing and scheduling, and by comparing the
results of an American case study to existing European case studies. We find the US and European
case studies to provide consistent results, that low customer density provides greater opportunities
for emissions reductions, and that logistical efficiencies can account for approximately 50% of CO2
reductions.
