Highlights ► Drayage trucks powered by diesel engines are a major source of emissions at ports. ► Voluntary vehicle replacement programs are a growing solution with mixed results. ► Programs have reduced harmful air emissions by 4% and should be customized locally.

    Abstract This paper analyzed three incentive-based, voluntary vehicle replacement programs underway at US ports using fleet baseline and program completion data and an emissions standard-based emission estimation methodology. The principal findings demonstrate that best management practices for voluntary clean truck programs can substantially reduce truck drayage emissions, although not to the level achieved through mandatory programs. Emissions reductions were found to be 1–4% as compared to potential reductions of 12–15% for particulate matter and 31–34% for nitrogen oxides.
