Question

How can emission standards control vehicular pollution? 

Answer 1

1. Emission standards limit vehicle emissions of hazardous gases and particles. These regulations require manufacturers to use cleaner engines and advanced equipment to minimize carbon monoxide, nitrogen oxides, hydrocarbons, and fine particle pollution. By doing so, emission limits reduce automobile pollution.
2. Cleaner fuels like CNG or electric alternatives are also encouraged to reduce vehicle pollution.
3. Regular testing and inspections ensure that road vehicles fulfil emission standards throughout their lifecycle.
4. This decreases highly polluting vehicles, making the environment healthier and cleaner for everyone.
