Increased usage of CNG

Pollution from vehicles can be reduced by:

1. Using efficient engines.

2. Switching off automobiles at red lights.

3. Using CNG. CNG (Compressed Natural Gas) burns cleaner than petroleum-based products because of its lower carbon content.

4. Using unleaded petrol. Leaded petrol contains lead additives. The combustion of leaded petrol causes the lead to be released into the air. Lead is a heavy pollutant that damages the central nervous system in animals and the environment.
