Revisions of Vehicular Emission Standards for Bangladesh - CASE

Proposed Revisions to Vehicle Emission Standards
countries like India where all the new vehicles after one year are required to present
themselves for inspection every 3 months.
The purpose of in-use vehicle emission inspection is to identify and repair the gross
polluters as it is often said that 20 to 30 percent bad vehicles contribute 70 to 80 % of
total vehicular pollution. More frequent emission inspection needs a very large number of
inspection centers in a large city with high vehicle population. To monitor functioning of
a large number of inspection centers so that the emission inspections are done correctly
and fraudulent practices are not resorted to, requires a very well organized and
technically skilled supervisory government/neutral body. In practice, it has been found to
be very difficult. In Table-19 frequency of emission inspection followed in EU and some
other countries are given.
