How to estimate lifecycle GHG emissions of transportation infrastructure

How to estimate lifecycle GHG emissions of transportation infrastructure
By Seth Hartley
Energy and greenhouse gas (GHG) emissions associated with the construction and maintenance of transportation systems are an important part of the total environmental impact of transportation. But estimating carbon emissions in transportation infrastructure can be difficult. 
To address this problem, a pooled fund study was commissioned to develop the Infrastructure Carbon Estimator (ICE), Version 2.1. The study was funded by multiple organizations, including departments of transportation (DOTs) in California, Colorado, Iowa, Minnesota, New York, Texas, and Washington State. Without the need for complex engineering studies, ICE provides a screening-level life cycle assessment of energy and GHG emissions. 
Learn more about this free tool and how it’s being used to quantify energy and GHG emissions as part of the environmental review process.
In this webinar, ICF developers and users at several state DOTs discuss the tool and how it helps answer how much carbon and energy is associated with the building, modification, maintenance, and/or use of a transportation project or group of projects.
