McNeil, W.H., Porzio, J., Tong, F. et al. Impact of truck electrification on air pollution disparities in the United States. Nat Sustain

Objective:

• Whether electrifying Class 8 heavy-duty trucks will reduce the absolute and relative air-pollution-related health burdens in disadvantaged communities and across different racial-ethnic groups over time with an evolving electricity grid mix

Case:

• US

Methodology:

• GREEM model for energy-related emission

Data Source

• Truck flow
• Grid electricity
• Diesel emission
• PM2.5

Findings:

• Battery-electric trucks reduce the relative share of air-pollution-related health impacts borne by disadvantaged communities relative to conventional diesel trucks

• The relative disparity between disadvantaged and non-disadvantaged communities increases steadily over time from 0.7% to 6.9%
