Reductions in pollutants including particulate matter, nitrogen oxides, carbon monoxide and others, help to clean the air – not just for children riding the bus, but everyone in the communities where these buses travel, as well as near the refineries where fuels are produced. But lower climate emissions aren’t the only benefit.
