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


Background l.jpg
Background

Vehicle exhausts

Quality and type of fuel

design and engineering

Age and population

Engine operating conditions

maintenance

Emission control devices


Background3 l.jpg
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


Background6 l.jpg
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)


Background7 l.jpg
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 l.jpg
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


Barriers to implementation l.jpg
Barriers to Implementation

Cost

Potentially prohibitive on an individual garage basis, but collectively possibly feasible

Human/personnel resource (training)

Train-the-trainer programmes


Slide10 l.jpg

Item Estimated Cost (USD)

Dynamometer for

testing NOx emissions under load

(including computer hard- and software and training)$18,000.00

5-gas analyzer(including training)$ 12,000.00

TOTAL $30,000.00


Slide12 l.jpg

  • 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
