Delaware’s Push to Cut Diesel Emissions Improves Air Quality Statewide

Many communities across the United States face challenges related to air quality and respiratory health, especially as it pertains to emissions from diesel engines. In Delaware, transportation is a major contributor to pollution, producing 75% of the state’s nitrogen oxide emissions, which contribute to the formation of ground-level ozone. But Delaware is also taking advantage of a federal program to clean up diesel pollution, replacing and retrofitting older diesel vehicles like school buses and trash trucks.
