People in low-income communities and communities of color are disproportionately affected by this pollution and can lack the resources to adapt or move away.
From garbage trucks to transit buses to “big rigs,” heavy-duty vehicles are a major source of air pollution. Emissions from these vehicles have been linked to adverse health impacts and are a significant contributor to global warming. For decades, trucks and buses have been powered by fossil fuels, but advances in clean technology are enabling these vehicles to shift to zero-emissions fuel sources. Battery- and fuel cell–electric trucks and buses are already being deployed in US cities, showing that these vehicles can provide new opportunities to clean up the air and lower global warming emissions in communities across the country.
