Explain how the use of CNG in automobiles has reduced pollution in our cities.

The integration of Compressed Natural Gas (CNG) as a fuel for automobiles has notably curtailed pollution in cities due to several key factors:

1. Emission Reduction: CNG exhibits cleaner combustion compared to conventional fuels like petrol or diesel. It significantly diminishes the release of harmful pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), and sulfur dioxide (SO₂) during the combustion process.

2. Lower Carbon Footprint: CNG contains fewer carbon atoms per unit of energy, leading to lower emissions of carbon dioxide (CO₂), a major contributor to greenhouse gases causing global warming.

3. Minimal Particulate Matter: CNG combustion generates minimal particulate matter, aiding in reducing air pollution and associated health hazards posed by fine particle inhalation.

4. Decreased Nitrogen Oxides: CNG engines produce lower emissions of nitrogen oxides, crucial components contributing to smog formation and respiratory problems.

5. Infrastructure Availability: CNG has a well-established refueling infrastructure in many urban areas, facilitating its widespread adoption in vehicles.

6. Noise Mitigation: CNG-powered engines tend to operate with reduced noise levels compared to diesel engines, contributing to diminished noise pollution.

7. Government Initiatives: Various governments have encouraged the adoption of CNG vehicles by offering subsidies, tax benefits, and enacting regulations aimed at combatting pollution.

The incorporation of CNG in automobiles has resulted in a noticeable decline in harmful emissions and improved air quality in urban centers. Nonetheless, while CNG vehicles offer environmental benefits, it’s important to consider the entire lifecycle impact, encompassing fuel production and distribution, for a comprehensive evaluation of their environmental footprint.
