The stagnation in air quality improvement poses significant health risks to Delhi's residents, particularly during winter when pollution levels peak. Vulnerable groups, including children, the elderly, and individuals with respiratory conditions, are at heightened risk. The regional nature of pollution means that efforts confined to Delhi alone are insufficient, leaving millions across the National Capital Region (NCR) exposed to harmful air. Without coordinated action across states, the health and environmental impacts are likely to persist, undermining long-term sustainability goals.
