Why 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

Role 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

2. Questions for appraisal of policy options to
tackle emissions from urban transport
8
Question 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.

9
Question 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.

10
Question 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.

11
Sources within the transport sector
12
Addressing emissions per unit of fuel consumed
  • Fuel and lubricant standards and options
  • Use of cleaner fuels
  • Vehicle emission standards, enforcement, and
    incentives
  • Ensuring compliance

13
Addressing 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

14
Reducing total transport
  • Restraining demand for movement
  • Integrating land use and transport planning
  • Influencing modal choice
  • Congestion pricing
  • Restraining private vehicle use
  • Parking policies

15
Possible Policy Instruments
  • Fuel Quality Improvement
  • Vehicle Technology Improvement
  • Traffic Management
  • Public Transport Regulation and Control
  • Vehicle Replacement Strategies
  • Land Use Policies
  • Fiscal Policies

16
Question 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

Air Quality in Dhaka
Note PM is the major pollutant of concern in
Dhaka.

Two 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).

20
Dimension 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

21
Getting 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.

22
Key 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

23
Final 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.

PM10 concentrations in Dhaka declined by 31
25
Health 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.)

26
Livelihood Impact
  • Drivers 86,000
  • Owners 10,000
  • Workshop owners 600
  • Mechanic and helpers 2,600
  • Dependents 500,000

27
Lessons 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.
