LPG-fuelled vehicles account for only a fraction of the pollution caused by even those petrol vehicles that comply with the latest Bharat Stage-VI emissions standards, according to tests conducted by Indian Auto LPG Coalition (IAC) industry group.
The group, which counts Indian Oil, Hindustan Petroleum, and Reliance Industries among members, has called for a reduction of GST rate as well as subsidy on conversion kits.
The tests compared petrol and auto LPG emissions across the key BS-VI parameters — carbon monoxide (CO), total hydrocarbons (THC), non-methane hydrocarbons (NmHC) and oxides of nitrogen (NOx). Auto LPG was found to emit almost 52 per cent less CO, 47 per cent less THC and 50 per cent less NmHC compared to the petrol vehicles, IAC said in a statement on Tuesday.
Passenger vehicles, including cars, two-wheelers, or three-wheelers, can switch to auto LPG by installing conversion kits.
