An integrated vehicular emission control programme for the city of Delhi using retrofitted emission control technologies

The City of Delhi, with a human population of over 16 million has nearly 9 million vehicles on its roads running over 100 billion kilometers every year, spewing out nearly 4 million tonnes of fuel emissions into the atmosphere every year (9900 tonnes per day). About 2 to 5% of these emissions (about 200 to 500 tonnes per day) are in the form of highly toxic gases and particulate matter hazardous to human health and well being. This does not include tyre wear out on Delhi roads which further adds nearly 6000 tonnes of rubber per year (about 16 tonnes per day!) into that contributes greatly to hazardous, dense, black carbon particles that tend to remain near the ground causing serious respiratory and heart diseases.
