We can reduce air pollution by :

1. Modifying automobile engines such that complete combustion of fuel takes place and less amount of harmful gases are released.
2. Using unleaded petrol will generate lead (poisonous) free exhaust and keep air cleaner.
3. Using CNG i.e. compressed natural gas that burns completely and produces less pollutants when used as automobile fuel.
4. Using cleaner souces of energy like hydroelectricity, solar energy, wind energy etc instead of burning fossil fuels (coal and petroleum) that on burning produce many air pollutants.
5. Using better filters at the exaust of vehicles.
