Abstract:This study developed a method of estimating energy and GHG emissions from construction and maintenance of transportation systems. Designed as a spreadsheet-based model for practitioners, FHWA’s Infrastructure Carbon Estimator is based on data collected from state DOTs, a nationwide database of construction bid documents, and consultation with transportation engineers and lifecycle analysis experts. The new tool improves upon previously available methods, which often require complex inputs or are based on outdated research. The Estimator allows users to create “ballpark” estimates of energy and GHG emissions using limited data inputs. This approach allows the tool to be used in transportation planning processes before details about specific facility dimensions, materials, and construction practices are known. The User’s Guide component of this document provides a step-by-step guide to using the tool itself. The spreadsheet tool is included alongside this user guide/report.
