Environmental Issues

Air pollution in metropolitan cities primarily arises due to vehicular emissions and industrial activities. To effectively control air pollution, practical measures must focus on reducing the use of fossil fuel-driven vehicles and promoting cleaner and efficient modes of transport.

• Metro Rail: Provides mass rapid transit reducing the number of individual vehicles on the road, leading to lower emissions.
• CNG Buses: Use compressed natural gas which burns cleaner than petrol or diesel, significantly reducing air pollutants.

Combining Metro Rail and CNG Buses offers a practical, sustainable solution for mitigating air pollution in cities.

Other options, although beneficial, either lack the emphasis on cleaner fuel (like Ring Railway) or on reducing individual vehicle use as effectively as Metro and CNG.
