A diesel-run SUV may be emitting between 25 to 65 times more NOx, a harmful gaseous pollutant, than a small petrol car, says a global study shared by Centre for Science and Environment (CSE). "Adding one diesel SUV to the city fleet in Delhi-NCR is equal to adding 25 to 65 small petrol cars in terms of nitrogen oxide, a very harmful gas that also forms deadly ozone," CSE said in a statement. The study was undertaken by International Centre for Automotive Technology (ICAT) and US-based International Council on Clean Transportation (ICCT), it said. Europe has already implemented this system," Anumita Roychowdhury of CSE's Right To Clean Air Campaign said.
