Vehicle Emissions Testing Equipment

Vehicle Emissions Testing Equipment

• Trinidad and Tobago
• UNFCCC Workshop on Innovative Options for
  Financing the Results of Technology Needs
  Assessments
  
• Bonn
• 20-21 October 2005

2
Background

• Vehicle exhausts
• Quality and type of fuel
• design and engineering
• Age and population
• Engine operating conditions
• maintenance
• Emission control devices

3
Background

• Current circumstances
• Ground transportation consists entirely of
  motorised road vehicles (no rail systems)
  
• Estimated rate of increase of 20,000 vehicles per
  year (all types majority privately owned)
  
• significant increase in vehicle fleet over past
  few years
  
• Increase in GHG emissions, ground level ozone
  generation
  
• Impacts on environment human health
• monitoring data suggests generation of ground
  level ozone coincides with peak traffic times

Background

• Current Inspection Regime
• Requires vehicles to be certified for road
  worthiness
  
• No emissions testing
• Current legislation provides for visible vapour
  penalty
  
• Emissions standards developed
• Testing conducted by private garages certified by
  Ministry of Works and Transport
  
• 26 USD once every two years 8 USD goes to
  consolidated fund
  
• 75 garages doing inspections (expected to
  increase)
  

7
Background

• Proposed Inspection Regime
• Emissions testing to be incorporated in
  inspection regime
  
• Legislative amendments
• Incorporation of emissions standards
• Use of emission control devices
• Revise fuel specifications
• Alternative fuels (CNG)
• On-the-spot testing by authorised personnel that
  would attract a fine (environmental police,
  traffic management )

Global and Local Benefits

• More efficient fuel combustion
• Decrease emission of GHGs
• Decrease in generation of ground level
  ozone
  
• Improvement in ambient air quality
• Human health benefits

9
Barriers to Implementation

• Cost
• Potentially prohibitive on an individual garage
  basis, but collectively possibly feasible
  
• Human/personnel resource (training)
• Train-the-trainer programmes

• Estimated 1200 inspections per year
• Income of USD 18.00 per inspection
• Net cash flow per inspection (considering table
  above) of USD 11.50
  
• Return period of 2.2 years per garage
