The Centre for Science and Environment (CSE) has revealed in the latest study that diesel powered SUVs and cars emit more toxic gases compared to petrol vehicles. The findings say that a diesel SUV may emit 25 to 65 percent more harmful gases than a small petrol car.
As per study findings, the Indian Pollution Under Control (PUC) certifications do not measure gaseous and particulate emissions from diesel vehicles.
In a statement, CSE said, "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."
The study was jointly undertaken by the International Centre for Automotive Technology (ICAT) and US-based International Council on Clean Transportation (ICCT).
As per claims, Indian laws are relaxed when it comes to NOx emission standards for diesel vehicles, especially under the BS-III and BS-IV standards. Facts reveal that although diesel vehicles make up only 25 percent in Delhi, they contribute to 78 percent of the PM2.5 from vehicles.
Pollution is a growing concern and measures are being taken to improve air quality. One such example is the recent order by the Supreme Court, which says vehicles cannot renew insurance without a valid PUC certificate. Pollution testing centres have also been directed to be monitored on a regular basis.
