Vehicular
Pollution Control in Delhi - Initiatives & Impacts
|
|
Foreword
Vehicular exhaust
is one of the major sources of air pollution in the metropolitan cities.
For the first time, a major initiative for vehicular emission control
and auto filel quality improvement was taken in the country when emission
standards for vellicles were notified under the Enviromnent (Protection)
Act in 1991. Also, efforts for improving the vehicular emission control
teclmology were introduced to meet the progressive tightening of vehicular
emission standards, which were enforced from 1996 and 2000 respectively.
Fuel quality standards were notified first time in 1996 under the
Enviromnent (Protection) Act 1986. Within a span of less than 5 years,
significant improvements "in vehicttlar emission norms and auto fuel
quality has been achieved particularly through total phasing out of
lead additive in petrol and reduction of sulphur in diesel.
At the instance of the Ron 'ble Supreme Court further improvement
in vehicular emission norms and auto fuel quality for the National
Capital Region has been achieved by adopting various controlling measures.
Similar efforts are being made to cover other metro cities
