Question

Ghissu Editorial · Accepted Answer

Air pollution causes asthma, COPD and heart disease, lowers productivity, damages crops and ecosystems through acid rain, and even cuts solar panel efficiency. It can be controlled through the National Clean Air Programme, BS-VI fuel and electric vehicles under FAME-II, electrostatic precipitators and scrubbers in industry, zoning and public awareness.

**Introduction**

Delhi’s air pollution⟦1⟧ crisis, especially winter smog⟦2⟧, exemplifies urban air pollution dynamics with severe health and economic impacts, necessitating urgent policy action. The city’s dense population and industrial activities compound the problem, making it a critical case for studying air pollution effects and control measures.

**1. Causes and Effects**

1. **Vehicular Emissions**: Vehicular emissions are the primary source of Delhi’s air pollution, releasing particulate matter and nitrogen oxides that intensify winter smog and respiratory illnesses. The adoption of Bharat Stage VI fuel standards aims to curb these emissions but enforcement remains a challenge.

2. **Health and Economic Impact**: Air pollution causes respiratory and cardiovascular diseases, contributing to millions of deaths globally; reducing pollution yields tangible health⟦3⟧ benefits and economic savings. Studies show that pollution-related illnesses reduce worker productivity and increase healthcare costs, straining the economy.

**2. Policy and Urban Challenges**

1. **Policy Gaps**: Delhi’s recurring winter smog reveals gaps in enforcement of emission standards and urban planning, exacerbating pollution levels despite existing regulations. Lack of coordination among agencies and inadequate public awareness worsen the situation.

2. **Government Measures**: The National Clean Air Programme (NCAP) targets a 40% reduction in particulate matter by 2025-26; promotion of electric vehicles and cleaner fuels under schemes like FAME-II are key steps. Additionally, initiatives like odd-even vehicle rationing and expansion of public transport aim to reduce vehicular pollution.

**Conclusion**

Combating Delhi’s air pollution requires closing policy gaps, enhancing enforcement, and adopting sustainable urban practices to safeguard public health and support economic growth. Strengthening inter-agency coordination and increasing public participation are essential for lasting improvements.
