A September 2000 study by the U.S. Department of Transportation shows that clean diesel buses are the most cost-effective option for reducing emissions from transit buses. Importantly, it reveals that a shift to non-diesel alternatives can have a negative effect on air quality by slowing the retirement of older buses due to the higher costs of purchasing and operating alternative fuel buses. Based on data from cities across the country, including New York City, CNG buses breakdown twice as often and are more than twice as expensive to maintain. CNG buses also require specialized fueling and maintenance facilities because of the risks posed by natural gas. The Diesel Technology Forum members are the nation's most progressive manufacturers and suppliers of diesel fuels, engines, fuel delivery systems, vehicles and components.
Some members also produce natural gas engines.
The Forum was assembled to create a new dialogue and encourage the full exchange of information and views on a full range of issues concerning today's diesels and tomorrow's advancing diesel technologies. All Rights Reserved.
