Comparison of construction equipment emissions for seven construction projects

This paper reports on the results of field studies of seven transportation infrastructure projects. The results of two road projects are compared to four street and utility projects and to a commercial building project. The study results show that road construction emits a much higher quantity of emissions than building construction; that the emissions calculated with published data are higher than those from field data; and that backhoes, motor graders, and bulldozers produce the highest total emissions. This paper adds to our understanding of emissions estimates from multiple project types and data sources.Non UBCUnreviewedFacultyOthe
