Subsidizing Pollution

A Euro III diesel car emits 7.5 times more particulate matter and three times more NO2 than a similar petrol car. A litre of diesel emits more carbon dioxide than a litre of petrol when burnt.

The Euro III norms that are currently in force in Indian cities use diesel with sulphur concentration ranging from 350 to 550 ppm. Diesel particulate filters require ultra-clean diesel with sulphur content of less than 10 ppm.
