Level of Emission due to Diesel Driven SUVS
In six cities namely Bangalore, Chennai, Delhi, Kanpur, Mumbai & Pune emissions of Particulate Matter (PM10 )from the transport sector is between 20 - 48 % , with 20.5% in Delhi and 48.3% in Chennai. This is shown in the report on Source Apportionment Study (SAS) carried out by the Central Pollution Control Board (CBCB) in collaboration with Ministry of Environment & Forests. The increase in number of vehicles directly causes more emissions and hence more air pollution. As regards the diesel Sport Utility Vehicles (SUVs), all diesel driven vehicles are known to cause higher emissions of Nitrogen Oxides (NOx) & particulate matter.

The Government has taken a number of measures for reducing emissions from vehicular sector which are as follows:

1) Bharat Stage (BS) –IV emission norms have been implemented in 13 cities of the country from 2010, while BS-III emission norms have been implemented in the entire country from 2010.
2) Future BS-IV compliant diesel vehicles are expected to have particulate traps for the reduction in particulates emissions and Selective Catalytic Reduction (SCR) system for NOx reduction in these vehicles.
3) The content of sulphur in BS-IV diesel has been reduced to 50 parts per million (ppm) from 350 ppm in BS-III diesel.
4) Improving the public transport system in terms of buses & rail to reduce the number of private vehicle.
5) Public transportation systems in various cities/towns are now running on clean fuels like Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG), electric vehicles etc.
6) Pollution Under Control (PUC) norms for diesel vehicles have been revised and made stringent from the year 2010.
