- 1. Breathing Clean: Considering the Switch to Natural Gas Buses
In response to emerging epidemiological evidence of the toxicity of diesel vehicular emissions, there is growing interest in substituting conventional diesel with much cleaner natural gas in cities where ambient concentrations of particulate matter are markedly higher than what is internationally considered acceptable. - 4.

The increasingly urbanized region served the Rogue Valley Transportation District (RVTD), home to nearly 130,000 people and situated in a valley at the convergence of the Cascade and Siskiyou mountain ranges in southwest Oregon, faces a continuing challenge to maintain air quality because of the local air shed's susceptibility to terrain-induced temperature inversions. - 12.

In 1986, the Pierce County Transportation Benefit Area Authority (Pierce Transit), based in Tacoma, Washington, made a commitment to the future of the transportation industry and to the environment by deciding to put buses powered by compressed natural gas (CNG) into everyday service. Eleven years, 72 CNG buses, and countless curious inquiries later, CNG is no longer a novelty it s business as usual. - 1. A Full Fuel-Cycle Analysis of Energy and Emissions Impacts of Transportation Fuels Produced from Natural Gas
This study reveals that, in general, the use of natural gas-based fuels reduces energy use and emissions relative to use of petroleum-based gasoline and diesel fuel, although different natural gas-based fuels in different vehicle technologies can have significantly different energy and emissions impacts. - 1.

Natural gas is a relatively clean transport fuel. which has been promoted both by government and industry in a number of countries. But not all promotional efforts have been successful, for good economic reasons. In the light of international experience this note considers the circumstances in which natural gas may play an important role, and attempts to identify appropriate policies for establishing that role in developing countries. - 2.
