Estimating and Reducing Road Carbon Emissions through Hybrid Life Cycle Assessment and Decomposition Analysis

Abstract

This research aims to estimate and reduce carbon emissions from use and maintenance and rehabilitation (M&R) of roads. An extensive literature review was conducted on related studies. A hybrid LCA approach was proposed to accurately estimate such emissions, which was embedded into a multi-attribute decision making framework to help road agencies select optimal network-level pavement maintenance plans. In addition, driving factors for vehicle-related emissions during 2009-2017 in Australia were investigated to establish emissions reduction strategies.
