"Actually, there are 20 indicators to judge pollution like access to drinking water, access to sanitation, waste water treatment, agricultural subsidies, pesticides regulation, change in forest cover, coastal shelf forest pressure, fish stalks, etc.
"So, this ranking which you are citing is not based on all these parameters...The survey of Yale University was also conducted from the satellite and there was no ground proof," he said, replying a question of BJD member Bhartruhari Mahtab.
Appreciating concerns expressed by members, the minister said no one should forget that number of vehicles has increased from eight crore on roads to 16 crore. So, it has doubled in ten years.
"So, formation of a new committee at this stage is not required because it will just kill time. Instead, whatever is already established we must go ahead on that part and we are committed to that," he said.
The minister expressed concern over increased use of diesel despite the gap between the prices of petrol and diesel being reduced.
"So, we hope that people will also switch over to petrol vehicles which cause less pollution. As regards diesel also, standards can be upgraded now and that can be done. It is a good suggestion for consideration," he said.
Javadekar said government is measuring pollution, particularly air quality, in at least 240 cities and is giving emphasis on use of public transport.
"Air pollution is caused by many factors. Roadside dust is a major pollutant in many cities, the number of vehicles and vehicular traffic causes air pollution. Apart from that, industries, construction work, secondary particulate, domestic and diesel generator sets cause pollution," he said.
The minister said government has changed diesel norms. So, the lead and sulphur contents have gone down and it was asking all state governments as well as the corporations concerned to take care of that.
