Clean Cities Top 20 Facts

Cummins Westport and American Honda lead the way in developing alternative fuel vehicles

Almost 18,000 stakeholders contribute to Clean Cities' goals and accomplishments by participating in nearly 100 Clean Cities coalitions across the country. Private companies, fuel suppliers, local governments, vehicle manufacturers, national laboratories, state and federal government agencies, and other organizations partner under Clean Cities to implement alternative-transportation solutions in local communities.

As part of Clean Cities' 20th anniversary this year, DOE recognized two long-time industry partners for their notable contributions to widespread deployment of alternative fuel vehicles (AFVs).

Cummins Westport: Longest continuously available heavy-duty dedicated AFV product line

Cummins Westport designs, engineers, and markets 6- to 12-liter spark-ignited natural gas engines for commercial transportation applications. Today, more than 34,000 Cummins Westport engines are in service worldwide. This includes the new 2013 ISX12 G 11.9-liter engine, a natural gas option for on-highway trucks—the largest automotive heavy-duty truck market in North America.

"Cummins Westport remained committed to develop robust products and make them continuously available to customers, even in the face of changing market conditions," said National Clean Cities Director Dennis Smith. "It worked hard to refine the technology and bring customers to the table, often in partnership with DOE, the national labs, Clean Cities coalitions, and vehicle manufacturers."

American Honda: Longest continuously available light-duty dedicated AFV product line

Honda first released the Civic Natural Gas in 1998. The vehicle was originally marketed primarily to fleet customers nationwide, and it is now available to fleets and retail consumers from select dealers across the country.

Over the years, Honda representatives have participated in hundreds of local and national Clean Cities events, providing education, information, and technical expertise as well as "loaner/demo" Civics.

"Honda has remained committed to this technology and to the vision of a transportation future in which natural gas plays a larger role," said Smith. "The company and its dealers have worked closely with Clean Cities coalitions to help fleets successfully incorporate these vehicles into their operations to cut petroleum use."

Fleets considering engine options like the Cummins Westport offerings or light-duty vehicle options like the Civic Natural Gas should consult the Alternative Fuels Data Center's (AFDC) Heavy-Duty Vehicle and Engine Search and Light-Duty Vehicle Search.
