What Happened
- A UN agency report released in June 2026 reveals that approximately 329 million children in India — representing 92% of the country's child population — are exposed to extreme heat, making India one of the most acutely affected nations globally.
- Around 89 million children in India are specifically exposed to dangerous heatwaves; the country received a high "hazard exposure score" in the Children's Climate Risk Index 2026.
- While over two dozen Indian states now have Heat Action Plans (HAPs), these plans largely lack child-specific provisions — gaps persist in protecting children in schools, anganwadis, and outdoor environments during peak heat hours.
- The report warns that exposure to extreme heat causes dehydration, heat stroke, impaired cognition, reduced school attendance, and long-term developmental harm in children.
- Ground-level ozone — worsened by heat — further compounds respiratory risks for children, who are physiologically more vulnerable than adults.

Children's Climate Risk Index (CCRI)
The CCRI was first introduced by UNICEF in 2021 as a composite index that ranks countries based on children's vulnerability to climate and environmental hazards. It combines two pillars: (1) exposure to climate and environmental hazards such as heatwaves, floods, cyclones, drought, air pollution, water scarcity, and vector-borne diseases, and (2) child vulnerability based on access to health services, safe water, sanitation, education, and social protection. India ranks among the 33 countries classified at "extremely high risk" and was placed 26th in the 2021 edition. The 2026 update finds that nearly 1.1 billion children globally face at least three overlapping hazards.
- Two pillars: hazard exposure + child vulnerability (access to services)
- India ranked 26th in 2021 edition; classified "extremely high risk"
- Drought, extreme heat, and heatwaves are the most prevalent trio of hazards globally
- Countries with large child populations — India, Nigeria, Pakistan, Bangladesh — top the absolute-number exposure charts
Connection to this news: The 2026 report updates this index and specifically quantifies how many Indian children are exposed to extreme heat, flagging the gap between existing HAPs and child-specific protections.
Heat Action Plans (HAPs) in India
A Heat Action Plan is a pre-planned, multi-agency framework that specifies early warning triggers, inter-departmental coordination, public communication, and emergency response protocols during heatwave events. Ahmedabad, Gujarat, pioneered South Asia's first Heat Action Plan in 2013 — developed after a devastating 2010 heatwave killed over 1,300 people. The Ahmedabad HAP is credited with avoiding more than 1,100 deaths annually through early warning systems and public outreach. The National Disaster Management Authority (NDMA) has since directed 23 heat-prone states to develop similar plans. By 2026, over two dozen states have HAPs, but implementation quality and child-specific provisions remain highly uneven.
- Ahmedabad HAP (2013): first in South Asia; developed by Ahmedabad Municipal Corporation with NRDC and PHFI
- Trigger mechanism: uses 7-day probabilistic weather forecasts from IMD
- NDMA defines a heatwave when maximum temperature reaches 45°C or more (absolute threshold), or departs from normal by 4–6°C depending on baseline
- Severe heatwave: departure of 6°C or more from normal, or absolute maximum ≥ 47°C
Connection to this news: The report calls out that while India has expanded its HAP network, these plans rarely contain provisions for children in schools or early childhood centres — a critical gap given that 329 million children face extreme heat exposure.
Heatwave Definition and NDMA Classification
India Meteorological Department (IMD) and NDMA use specific temperature thresholds to declare heatwaves: (1) when maximum temperature ≥ 45°C irrespective of normal maximum; (2) when departure from normal maximum temperature is 4–5°C (heatwave) or ≥ 6°C (severe heatwave) for stations with normal maximum > 40°C; (3) for coastal stations, heatwave threshold is ≥ 37°C.
- Plains heatwave threshold: 40°C or more; hills threshold: 30°C or more
- Heatwave declared when actual max ≥ 45°C (plains, absolute threshold)
- Severe heatwave: ≥ 47°C (absolute)
- India's National Action Plan on Climate Change (NAPCC, 2008) contains 8 national missions; heat is addressed under the National Mission for a Green India and National Mission for Sustainable Agriculture
Connection to this news: Without standardised child-specific heat triggers embedded in HAPs, existing thresholds that may be appropriate for adults can still expose children to dangerous conditions well below those thresholds.
Ground-Level Ozone and Child Health
Ground-level ozone (O₃) is a secondary air pollutant formed when nitrogen oxides (NOₓ) and volatile organic compounds (VOCs) react in the presence of sunlight. Heatwaves significantly accelerate ozone formation. Unlike stratospheric ozone which shields from UV radiation, tropospheric ozone is harmful, causing respiratory distress, reduced lung function, and aggravating asthma. India's National Ambient Air Quality Standards (NAAQS) set 8-hour average ozone standard at 100 μg/m³. Children are more susceptible because they breathe faster relative to body weight and spend more time outdoors.
- Formed from: NOₓ + VOCs + sunlight (photochemical reaction)
- Worsened by higher temperatures and stronger UV radiation
- NAAQS ozone standard: 100 μg/m³ (8-hour average)
- Children, elderly, and those with pre-existing respiratory conditions most vulnerable
Connection to this news: Heat and ozone operate as a compound hazard for children, meaning policies focused solely on temperature miss the full risk picture.
