Diesel-powered vehicles have long been efficient work horses in America and world wide. They will continue to play an economically critical role of moving people and goods. While new diesel engines are becoming cleaner, older diesels are highly polluting. They contribute significantly to respiratory diseases, cancer, heart disease, nervous system impairment and premature death. According to published studies, people who work in and around diesel vehicles, those living close to diesel “hot spots,” children riding diesel school buses, and the elderly are at greatest risk.

For these reasons, Ohio Green Fleets focuses particular attention on cleaning up and/or replacing diesel powered vehicles. Any individual cleanup action such as a retrofit device or cleaner fuel will make an impact. However, the greatest and most cost effective approach will be to develop and implement a comprehensive strategy, which we and others have called the “Six R’s of Diesel Cleanup," which are listed below:

Reduce fuel use.
Refuel with cleaner fuels.
Retrofit existing vehicles.
Rebuild older diesel engines.
Repower older diesel engines.
Replace older diesels with newer engines.
