Alternative fuels for buses are helping cities reduce their environmental impact. Some cities have implemented hybrid-electric buses that produce less noise and pollution than diesel buses. Other cities use all-electric buses that are charged at stops and produce no emissions. Compressed natural gas buses also emit less carbon than gasoline buses. National parks are also transitioning to more sustainable transportation by using buses powered by propane or biofuels to shuttle visitors through sensitive areas.

Over the past decade, environmentally beneficial public transportation has caught on in many
urban areas. As more and more city dwellers begin to rely on public transportation, cities are
working to implement transit systems that emit less carbon dioxide and add less to global warming.
New fuel technology for buses can further accelerate these solutions:

- Hybrid-electric buses. Baltimore, Maryland, has created a program called Charm City Buses.
These buses are free to ride and produce less noise and pollution than diesel ones.

- All-electric buses. Louisville, Kentucky’s Zero Bus fleet runs entirely on electricity and is much
cleaner than the old diesel trolleys. The system features charging stops where buses stop several
times per day while passengers get on or off.

- Compressed natural gas (CNG) buses. Although the CNG buses in Ft. Collins, Colorado, get
about the same mileage as their gasoline-powered counterparts, they are quieter and release less
carbon.

- Other uses. The popularity of America’s national parks poses new environmental problems.
Mammoth Caves and Zion National Park have moved toward sustainability by transporting visitors
in alternative-fuel buses driven by propane and biofuels.
