Impact on Air Quality: The continued operation of coal plants at sub-optimal standards, combined with other factors such as crop burning and vehicle emissions, has resulted in Delhi facing some of the worst air pollution levels. The city remains enveloped in a thick layer of smog, especially in the winter months, posing severe health risks to its residents.

Role of Coal in Pollution: Coal-fired power plants are a significant source of particulate matter (PM2.5) and other pollutants that worsen air quality. Despite efforts to reduce their impact through technology upgrades and emission control measures, many plants are still operating below acceptable environmental standards.

Government Measures and Delays: The Delhi government has implemented several measures, including the relocation of some coal plants and mandating cleaner technologies. However, the delay in meeting the emission reduction targets has been criticized by environmental experts and activists, who argue that these measures are insufficient to combat the growing pollution problem.

Health Risks and Fatalities: The increased pollution levels in Delhi are linked to a rise in respiratory illnesses, heart diseases, and premature deaths. Vulnerable groups, such as children and the elderly, are at higher risk of experiencing severe health effects due to prolonged exposure to toxic air.

Push for Renewable Energy Transition: Experts have urged the government to accelerate the transition to renewable energy sources, reducing dependency on coal-based power generation. Investing in solar, wind, and other cleaner alternatives is seen as the most viable long-term solution to addressing Delhi's pollution and contributing to national climate goals.

Conclusion: The failure of coal power plants to meet emission reduction targets is a critical factor in Delhi's ongoing air pollution crisis. As the capital city struggles with toxic smog, urgent actions, including accelerating the shift to renewable energy and enforcing stricter emission controls, are necessary to safeguard public health and improve air quality. Addressing this issue is key to mitigating the long-term environmental and health consequences posed by Delhi's pollution.
