Camilleri, S.F., Montgomery, A., Visa, M.A. et al. Air quality, health and equity implications of electrifying heavy-duty vehicles. Nat Sustain 6, 1643–1653 (2023)

Objective:

• The associated air-quality and public health implications that have not yet been widely assessed at the fine spatial resolutions needed to determine different exposure between population subgroups in urban setting

Case:

• Lake Michigan

Methodology:

• WRF-CMAQ model
• SMOKE system
• Multiscale air quality model: CMAQ

Data Source: Open

• Vehicle-to-EGU electricity assignment and emission remapping algorithm: EPA
• Population and demographic: American community survey
• Incidence rate: Industrial economic, incorporated

Findings:

• An instantaneous transition to 30% eHDVs results in on-road emission reductions that more than offset emission increases from EGUs
• The highest-magnitude emission reductions occur along major road networks and within densely populated areas

• 30% adoption of eHDVs reduces population-weighted PM2.5 concentrations

• 0.42%-0.05% decreases of all-cause baseline mortality are associated with reductions in NO2 and PM 2.5
