New Delhi: HL July 30, 2026
A new analysis highlights that Delhi-NCR, home to only 5% of India’s population, accounts for nearly 23% of child asthma cases linked to vehicle emissions. The International council on clean transportation report also points to thousands of premature deaths associated with transport-related air pollution.
High Child Asthma Cases Linked to Traffic Pollution
Delhi-NCR has emerged as one of India’s biggest hotspots for transport-related air pollution, with a recent analysis indicating that the region contributes a significantly higher share of childhood asthma cases than its population size would suggest.
According to the report, Delhi-NCR is home to nearly 5% of India’s population but accounts for around 23% of child asthma cases associated with vehicle emissions, translating to approximately 3,500 new cases annually. The findings underline the growing public health impact of traffic-related pollution in densely populated urban areas.
The report also estimates that around 8,100 premature deaths in Delhi-NCR during 2024 were linked to vehicle emissions. In Delhi alone, approximately 2,800 premature deaths were associated with traffic-related pollution over the same period.
Researchers note that pollutants such as nitrogen dioxide (NO₂) and fine particulate matter (PM2.5) remain among the primary health concerns. Heavy-duty vehicles, including trucks and buses, contribute disproportionately to these emissions despite representing a smaller share of the total vehicle fleet.
The analysis suggests that pollution exposure is especially harmful for children, whose lungs are still developing. Frequent exposure to polluted air during daily activities, including commuting to school, increases the risk of respiratory illnesses such as asthma.
Experts cited in the report recommend accelerating the transition to cleaner transportation, expanding public transport, promoting electric vehicles, and implementing stricter emission-control measures. They also emphasize improving urban planning and reducing dependence on fossil-fuel-powered vehicles to protect public health.
The findings reinforce concerns that transport emissions remain a major environmental and health challenge for the National Capital Region, highlighting the need for coordinated action to improve air quality and reduce disease burden.
