Since 1975, the Indian economy has grown 2.5 times while the vehicular pollution load has grown 7.5 times.The deteriorating air quality in India can be attributed to the increase in the number of vehicles and uncontrolled industrial and urban growth. Power plants and toxic fumes from garbage dumps also add to the pollution load. Emission standards that have come into practice as far back as 1992-93 in European countries are only just being adopted in India. Our national standard for suspended particulate matter in residential areas is 2.3 times the 60 micrograms per cubic metre guideline recommended by the World Health Organisation (WHO). The main perpetrator of lead emissions into the air in our cities is leaded petrol. Diesel in India has 50-200 times more sulphur than diesel in Europe.
