Department of Transportation
Staff Study: The
Purchase and Use
of Compressed Natural Gas Buses by Public Transit Systems
Public transit systems in New York State are
overseen by the Department
of Transportation, which provides the systems with financial aid
and technical assistance.
Most of the buses used by these transit systems are powered by
petroleum-based diesel fuel,
the emissions from which are a significant source of air
pollution. To reduce these emissions
as well as to reduce America's dependence on imported petroleum,
transit systems have begun
to purchase buses powered by compressed natural gas. We reviewed
these purchases and
determined that, compared to diesel buses, natural gas buses have
both advantages and
disadvantages. For example, while natural gas buses emit fewer
pollutants, they tend to have
higher purchase and operating costs. We conclude that transit
system operators, in
conjunction with Department officials, should continue to assess
the costs and benefits of
natural gas buses.
