Improvements to the Infrastructure Carbon Estimator (ICE)

Some state departments of transportation (DOTs) and many Metropolitan Planning Organizations (MPOs) have begun to estimate vehicle greenhouse gas (GHG) emissions from the transportation systems. However, only a few have started to evaluate infrastructure-related energy consumption and GHG emissions, which can make significant contribution to the environmental footprint of the transportation system. The goal of this project is to update the Federal Highway Administration (FHWA) Infrastructure Carbon Estimator (ICE) tool used to estimate GHG from construction of transportation projects. The project was organized to gather stakeholder input and implement the following ICE improvements: (1) Incorporate new research on infrastructure embodied energy and lifecycle greenhouse gas emissions; (2) Add analysis of new/additional project types; (3) Address GHG reductions and energy conservation potential of additional reduction strategies; (4) Tailor outputs to better address the energy and GHG emissions from transportation project alternatives and transportation plans; (5) Make the interface more intuitive and easier to use; and (6) Allow for states to input emissions factors most relevant to them as opposed to national averages.
