Greenhouse Gas Mitigation Measures for Transportation Construction, Maintenance, and Operations Activities

NCHRP Project 25-25/Task 58 developed a spreadsheet-based calculator tool, the Greenhouse Gas Calculator for State Departments of Transportation (GreenDOT), as its primary product. The tool estimates CO2 emissions from state Departments of Transportations’ (DOTs’) construction, maintenance, and operations activities, including: Emissions from electricity used in roadways; Emissions from on-road vehicle fleets; Emissions from off-road equipment; and Emissions embodied in materials used in roadway construction. The report's sections provide an overview of each major category of emissions, along with a description of mitigation strategies and key examples from the literature. Strategies that reduce congestion are also briefly discussed. Quantified impacts of strategies are provided wherever possible. In each section, links to Quick Reference Tables are provided. Quick Reference Tables compare emissions across vehicle, technology, and material types. Research gaps and recommendations for additional research projects are included under each emissions category. Overarching research gaps are discussed in the final section of the report.
