A research by Centre for Science and Environment (CSE) has found out that diesel-run SUVs may be emitting between 25 to 65 times more NOx (Oxides of nitrogen), a harmful gaseous pollutant, than a small petrol car.  CSE said the findings assume significance as the country's existing Pollution Under Control (PUC) certification system does not measure gaseous and particulate emissions from diesel vehicles on road.

According to the statistics shared by Non- profit organisation, adding one diesel SUV to the fleet of cars is equal to adding 25 to 65 small petrol cars in terms of nitrogen oxide, a very harmful gas that also forms deadly ozone.

The study was undertaken by International Centre for Automotive Technology (ICAT) and US-based International Council on Clean Transportation (ICCT) said CSE.

?As already implemented in many countries in Europe India must also adopt tighter test procedures for vehicle certification as well as implement direct monitoring of actual emissions while vehicles are driven on road? said an official from CSE.

 Concerned over rising vehicular pollution, the Supreme Court of India had on August 10 issued a slew of directions, including non-renewal of insurance policy of vehicles unless the owner provides pollution under control (PUC) certificate to the insurance firms.
