Causes of Black Smoke from Diesel EngineCauses of Black Smoke from Diesel Engine
5
Why is Diesel a Problem for Air Quality?
Used by heavy duty traffic Significant emitter of fine particulates, SOx, NOx (secondary PM) associated health impacts
Diesel vehicles have a long life time delays introduction of latest technology
Black smoke major visible nuisance
6
Reducing PM from diesel vehicleReducing PM from diesel vehicle
1) Cleaner new vehicles and fuels• Low Sulfur fuels• Alternative fuel vehicles, i.e. NGV, hybrid,
Bifuel,etc., Biodiesel, Gasohol
• Fuel cell, etc 2) Promoting and Implementing preventive
maintenance program3) Improving I/M program4) Retrofit program
5) Emission control device
7
Emission Control Options Economic: (differentiated) taxes,
subsidies, pricing (congestion, parking) Administrative: emission, energy
efficiency and fuel quality standards, restrictions on operation (vehicles, parking), previous history
Technological: fuel improvements, new technologies, CNG retrofit, control devices
Transport policy: traffic management, public transport, NMT
8
A Quick View of the Components
1. Database Development
• Collation of available data and reports• Vehicle testing for emission factors• GIS-based knowledge base development
2. Analysis of Options
• Identification of Policy, Institutional, Economic and Technical Options• Development of the IDEAS tool for analysis of alternative options• Building synergies with other analytical efforts
3. Synthesis and Outreach
• Consultations/Dissemination of data and analytical work• Selection of management options• Action Plan preparation
9
Criteria for Option Selection
Cost and benefits Which measures are (likely) the most cost-
effective (Bath/population exposure reduced)? Compatibility with other sector objectives
Do the measures reinforce existing sector objectives and economic incentives?
Political feasibility Is there broad support from public and
stakeholders for the measure? Ease of enforcement
How difficult is the implementation and enforcement of the measure?

How to find sustainable action?
Compatibility with other sector objectives Do they go against, or reinforce, other sector
objectives? Political feasibility
Are there interest groups that would oppose the proposed measures vigorously?
Cost of implementation Which measures would be the most cost-effective
(Rs / population exposure reduced)? Ease of enforcement
How difficult would it be to carry out the proposed measures or to enforce them?
13
Improving urban air quality requires coordination of:
policies and actions of many sectors; and
stakeholders from local to national and regional/global levels
Think Big and Take Small Steps
Concluding RemarksConcluding Remarks
While technical solutions are available, political commitment and institutional issues are most critical in generating positive change
Information and public awareness of urban air pollution levels and impacts are key to support policy change and local action
“Best” steps must weight: Technical feasibility; Cost-Benefit; Political viability; Financial feasibility; Social Acceptability

What is the Clean Air Initiative?
The Clean Air Initiative for Asian Cities The Clean Air Initiative for Asian Cities is designed to be a network assisting is designed to be a network assisting cities in Asia to solve their air quality cities in Asia to solve their air quality problems. The initiative was problems. The initiative was established recently by a group of established recently by a group of cities, NGO’s and organizations, cities, NGO’s and organizations, including the World Bank, ADB, DBJ, US-including the World Bank, ADB, DBJ, US-AEP & EPA, Ford Motors, GTZ, SDC, AEP & EPA, Ford Motors, GTZ, SDC, Hong Kong EPD, ESCAP, and many Hong Kong EPD, ESCAP, and many others.others.
