This module presents a brief overview of the methods commonly used to quantify the health impacts of air pollution and to value them. We focus on translating changes in ambient air quality into associated cases of premature mortality and morbidity and on the methods used to value these health effects. A case study Improving Air Quality in Metropolitan Mexico City: An Economic Valuation, is used to illustrate the application of these methods. - Vehicular Air Pollution: Setting Priorities - Gwilliam, Kenneth G.Kojima, Masami
Air pollution is viewed as a serious problem in many cities in South Asia. Many city governments hold transport largely responsible and have adopted, or are considering, technological measures to reduce vehicle emission. This note outlines a framework for the appraisal and selection of appropriate measures in the sector. - Transporte Sustentable: Un Libro de Partida para los Hacedores de Políticas en las Ciudades en Desarrollo - Breithaupt, Manfred

- Urban Air Pollution - How Can Urban Bus Policy Reduce Air Pollution? - Akbar, SameerGwilliam, Kenneth G.Kojima, Masami
Buses are essential to everyday life in South Asia. They affect urban air quality both directly by emitting air pollutants and indirectly by reducing the congestion and emissions caused by the many smaller vehicles which they replace. - Transport Fuels Taxes and Urban Air Quality - Bacon, RobertGwilliam, Kenneth G.Kojima, MasamiLvovsky, Keseniya
In developing country cities, fuel use for transport is a growing contributor to air pollution and environmental health risks. One way of applying the "polluter pays " principle to transport is to adjust fuel taxes to reflect environmental externalities. But in setting tax rates on fuels, many factors need to be considered. - Reducing Air Pollution from Urban Passenger Transport: A Framework for Policy Analysis - Heil, MarkPargal, Sheoli
This paper develops a simple framework to analyze various pollution control strategies that have been used or are proposed in the urban passenger transport sector. The context is the declining quality of air in urban areas, which is among the serious problems associated with the rapid motorization of societies the world over. - Coordinating Environment, Transport, and Energy Policies for Cleaner Air - Kojima, MasamiLovei, Magda
Poor urban air quality causes serious environmental health damage in many developing countries. Arriving at effective and sustainable solutions to these problems requires a broad approach that takes into account the various sources of pollution, focuses on cost-effective and feasible interventions, involves affected stakeholders in decisionmaking, and coordinates policies across multiple sectors. An important challenge is to evaluate when and how environmental considerations should be reflected in sector policies. This note illustrates these points, taking urban air pollution from transport as an example. - Abuses in Fuel Market: How to Protect Consumers in Public - Bacon, RobertKojima, Masami
In the fuel business, smuggling, adulteration, mislabeling and short-weighting are widespread in many developing countries. - Breathing Clean: Considering the Switch to Natural Gas Buses - Kojima, Masami
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.

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. - Pierce Transit, Tacoma, Washington, US
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. - The Role of Natural Gas in the Transport Sector - Gwilliam, Kenneth G.
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. - Euro 2 and Beyond - Fuel for Transperth's Bus Fleet - Bult, Brian

Finally, it undertook an economic analysis, which was then used as a baseline to factor in the economic costs of various environmental impacts. - An Assessment of the Emissions Performance of Alternative and Conventional Fuels - Lane, BenLillie, KenMcCallum, JoshuaMurray, Jonathan

Petroleum-based gasoline and diesel fuel account for nearly all of the fuel used in onroad vehicles today. Concerns about the environmental effects of fossil fuel use and the Nation s dependence on foreign oil are providing the impetus for increasing use of alternativefueled vehicles (AFV s) and alternatives to traditional transportation fuels. - Sun Metro, El Paso, Texas, US
Sun Metro, the public transportation authority of El Paso, Texas, operates the world s largest natural-gas-fueled mass transit fleet. Approximately 53% of Sun Metro's fleet of 240 vehicles - buses, paratransit vehicles, and support vehicles - runs on natural gas. - Rogue Valley Transport District, Rogue Valley, Oregon, US - Giardina, Larry
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. - Pierce Transit, Tacoma, Washington, US
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. - The Role of Natural Gas in the Transport Sector - Gwilliam, Kenneth G.
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.
