5Why do We Care About Urban Air Pollution?
The relative burden of environmental damages
- Human health impacts
- WHO estimated more than 150,000 attributable
deaths to urban air pollution in South Asia in
2002. - Morbidity numbers are much higher.
- Other environmental externalities and concerns
- Damage to natural and physical capital, amenity
losses, noise, contribution to climate change

6Role of Urban Transport
- Important contributor to air pollution
- Lead from gasolinea problem of the past in South
Asia as they have phased out leaded gasoline - Fine and ultrafine particles in vehicle
exhaustmain concern now - Ozone precursors (HC and NOx) in vehicle
exhaustemerging problem for the future - Current reality
- Old polluting fleets and low replacement rates
- Fuel adulteration, poor fuel quality and vehicle
maintenance culture - Weak administrative capacity to regulate and
monitor - Future challenge
- Rising income and motorization will increase
pollution unless concerted measures are taken
72. Questions for appraisal of policy options to
tackle emissions from urban transport
8Question 1 Are the adverse impacts of urban air
pollution serious?
- Is the impact of urban air pollution on public
health and lost productivity considerable
compared to other threats, such as - Lack of access to safe drinking water
- Extensive use of dirty fuels in households
- Yes identify problem pollutants
- No look for environmental benefits that can be
achieved through no regret adjustments to
transport policy.
9Question 2Which pollutants cause the most damage
?
- Pollutants should be ranked according to
toxicity, ambient concentrations, and exposure. - Fine particulate matter is the pollutant of most
concern in South Asia. - A common mistake is to rank on the basis of
emissions in weight based on an emissions
inventory. - Toxicity is not taken into account.
- Emissions in weight are not directly proportional
to ambient concentrations or exposure.
10Question 3 Does transport contribute
significantly to the problem pollutants?
- Need to identify the relative significance of
sources contributing the most to the general
populations exposure to fine particulate air
pollution. - Large industrial plant
- Small and medium size industries, diesel
generators. - Household consumption of solid fuels (biomass).
- Vehicular emissions.
- Leaf and informal refuse burning.
- Re-suspension of road-dust.
- Yes identify sources within the transport sector
- No look for environmental benefits that can be
achieved through no regret adjustments to
transport policy.
11Sources within the transport sector
12Addressing emissions per unit of fuel consumed
- Fuel and lubricant standards and options
- Use of cleaner fuels
- Vehicle emission standards, enforcement, and
incentives - Ensuring compliance
13Addressing fuel consumption per unit of transport
service
- Increasing vehicle fuel efficiency
- New and improved technology
- Encouraging non-motorized transport
- Provision of pedestrian spaces and cycle lanes
- Improving traffic management
- Traffic signaling systems
- Supporting fiscal incentives
- Introducing competition in franchising of public
transport
14Reducing total transport
- Restraining demand for movement
- Integrating land use and transport planning
- Influencing modal choice
- Congestion pricing
- Restraining private vehicle use
- Parking policies
15Possible Policy Instruments
- Fuel Quality Improvement
- Vehicle Technology Improvement
- Traffic Management
- Public Transport Regulation and Control
- Vehicle Replacement Strategies
- Land Use Policies
- Fiscal Policies
16Question 4 How to decide on policy instruments
to be used?
- Summary considerations.
- Urban transport policy will be driven by mobility
and development concerns - Seek synergies with transport objectives and face
trade-offs to reduce air pollution - One size doesnt fit all !
- The institutional and policy framework is
fundamental to long-term solutions - Technology will provide major environmental gains
but will rarely be successful in a vacuum - Work with and not against economic incentives

19Two Stroke Three-wheelers a problem in Dhaka
- About 50,000 two-stroke engine gasoline-fueled
three-wheelers, nicknamed baby-taxis, provided
useful point-to-point transportation for Dhaka
population. - These were major sources of particulate and
hydrocarbon emissions in Dhaka. - Emissions were exacerbated by the use of
inferior-quality and excess lubricant (called
straight mineral oil).
20Dimension of the strategy
- Understanding of the Problem Health, Technical
options, Social, Fuel and Lube, dissemination,
economic, etc. - Stakeholder consultation extensive throughout
the process a key - Public awareness and support through information
dissemination media support - Vision milestones, legal conditions, etc.
- Policy support and use of Import tariffs
- Praying - for a political champion
21Getting on the Right Track
- Identifying and meeting stakeholders to
understand different views issues (1996) - Study tour of stakeholders to India (1997)
- Continuous liaison with press - 1996 onwards
- Workshop on AQM in Dhaka to better understand
emission sources and issues (1998) - Survey of public opinion found good support
- Proposed Baby Taxi phase-out by 1st Jan. 2003 in
WB-funded Dhaka Urban Transport Project (DUTP) as
a legal covenant a phased approach.
22Key Actions Undertaken in 1999-2000
- DUTP Covenants Implemented
- BRTA stopped registration of 2-stroke 3-wheeler
by July, 1999 - GOB imposed 200 Supplementary duty on 2-stroke
3-wheeler in July, 2000 effectively banning
import - Training and Capacity Building
- Training for mechanics (April 2000) 427
mechanics trained in maintenance for emission
reduction. - Auto-clinics (Oct.-Nov. 2000) Emission reduction
demonstrated with the use of better lubricants
and maintenance on 1000 vehicles. - Seminar on Lube oil and Gasoline Quality for Air
Quality Improvement Nov. 21, 2000 - Revision of lube oil standards by BPC 1st
January, 2001
23Final Countdown To Phase-out
- August 2002 Earlier plan revised with
stakeholder input for a two stage phase-out --
1st Sept. 2002 (pre-1995) and final 1st Jan.
2003. - 1st Sept. 2002 First step of phase-out executed
gt Air is Cleaner! - Baby-Taxis go on a 3-day strike.
- Strong press and public support for phase-out
demonstrated. - Replacement CNG-powered 4-stroke 3-wheelers start
arriving as a result of lowering of taxes. - 1st Jan. 2003 Phase-out completed gt Air is much
cleaner! - Good public support but some criticism in media
for failure to address the phase-out impact. - Quite serious transport dislocation.
- Social impact partially addressed Some owners
and drivers were provided with 4-stroke
3-wheelers and bus leases through their
associations. But no serious protest from the
affected groups.
24PM10 concentrations in Dhaka declined by 31
25Health Benefits
- Estimated decline in average yearly PM10 level of
24 ?g/m3 - More than 900 premature deaths estimated to be
avoided per year - About 25 million estimated to be saved in health
maintenance costs per year - (Methodology Used K. Lvovsky et al
Environmental Cost of Fossil Fuels A Rapid
Assessment Method with Application to Six Cities,
Environment Department Paper No. 78 (2000), The
World Bank, Washington.)
26Livelihood Impact
- Drivers 86,000
- Owners 10,000
- Workshop owners 600
- Mechanic and helpers 2,600
- Dependents 500,000
27Lessons Learnt
- Socially difficult environmental decisions can be
executed if there is strong support from the
public. - Public support can be created by working with the
stakeholders and the press on genuine issues. - Ultimately such decisions are fundamentally the
result of political - Correct management of technical issues help to
create the room for the political will. - Careful and long-term planning is needed for the
mitigation of adverse impacts on both the public
and the stakeholders. - The transport services lost was not replaced
immediately (or soon after), and this created
disruptions to transport services, has led to the
entry of private diesel buses, thus negating some
of the gains of air quality improvement.
