Has air quality improved in Delhi?
Delhi
has been categorized as the fourth most polluted city of the world in
a list of 41 cities. Burning of fossil fuels has added to the
pollution of air in Delhi.
Various
steps have been taken to improve the quality of air in Delhi.
(a) Introduction
of CNG (Compressed Natural Gas):By
the orderof
the supreme court of India, CNG-powered vehicles were introduced at
the end of year 2006 to reduce the levels of pollution in Delhi. CNG
is a clean fuel that produces very little unburnt particles.
(b) Phasing
out of old vehicles
(c) Use
of unleaded petrol
(d) Use
of low-sulphur petrol and diesel
(e) Use
of catalytic converters
(f) Application
of stringent pollution-level norms for vehicles
(g) Implementation
of Bharat stage I, which is equivalent to euro II norms in vehicles
of major Indian cities.
The
introduction of CNG-powered vehicles has improved Delhi’s air
quality, which has lead to a substantial fall in the level of CO2
and SO2.
However, the problem of suspended particulate matter (SPM) and
respiratory suspended particulate matter (RSPM) still persists.
