Delhi pollution | Schools told to improve ventilation, curb dust and check firecrackers: Inside new Winter Action Plan

Delhi schools have been asked to reduce pollution on their campuses and limit students’ exposure to harmful air from October 2026 to February 2027. The instructions apply to government-aided and private unaided recognised schools under the Winter Action Plan 2026–27.

Schools must sprinkle water in open areas, improve classroom ventilation, expand green patches and avoid construction that creates dust. They must also prevent open burning, promote public transport and carpooling, encourage recycling and reuse, and switch off unused lights. Electric heaters should be provided to certain staff to prevent waste burning.

The plan also includes anti-firecracker campaigns, pollution-awareness activities and applicable GRAP measures. Schools must submit monthly progress reports through a designated Google Sheet. Community involvement is encouraged through parent-teacher and School Management Committee meetings, while air purifiers will be installed in phases.

The Graded Response Action Plan, or GRAP, is a staged system for responding to worsening air pollution. Under this framework, authorities apply increasingly strict measures when air quality reaches different levels. Its purpose is to reduce pollution quickly and protect people when conditions deteriorate. The article names GRAP as one measure schools must implement, but does not describe its individual stages.

At school level, GRAP-related action can work alongside dust control, better ventilation and restrictions on dust-generating construction. Schools may also support lower emissions by promoting public transport, carpooling, recycling and reuse. These steps address pollution sources around campuses and reduce exposure inside buildings.

The Winter Action Plan applies from October 2026 to February 2027. School heads must report progress monthly. The article does not specify which particular GRAP measures each school will use, so implementation will depend on applicable conditions and official directions.

The first phase of the government’s proposed air-purifier programme covers 10,000 classrooms in government schools. The plan is part of a wider effort to improve indoor air quality and reduce children’s exposure during Delhi’s polluted winter period. Installation is described as phase-wise, so the first phase is not the complete programme.

Other measures begin across schools during the action-plan period. These include improving ventilation, sprinkling water in open areas, increasing green patches and preventing dust-generating construction. Some schools are also considering installing air purifiers. Tania Joshi, principal of The Indian School, said her school was considering them.

The measures are scheduled to run from October 2026 to February 2027. School heads must submit monthly progress reports by the last day of each month. This reporting system will help the Directorate track how schools are applying the plan and guide continued action.

Delhi’s air quality usually deteriorates during winter because several pollution sources contribute at the same time. The article identifies vehicular emissions, construction dust and industrial pollution as important contributors. It also points to weather conditions that contribute to higher pollution levels during the season.

These sources add pollutants to the air around homes, roads and schools. Traffic releases emissions, construction creates dust, and industrial activity adds pollution. When winter conditions contribute to higher pollution levels, people can face greater exposure to harmful air. School campuses therefore become important places for reducing exposure.

The Winter Action Plan responds by requiring dust control, better ventilation, greener campuses and fewer dust-generating activities. Schools must also encourage public transport and carpooling to reduce vehicle emissions. The seasonal measures are scheduled from October 2026 through February 2027, when Delhi’s air quality typically worsens.

Repeated exposure to polluted air can harm children’s health because children are particularly vulnerable to poor air quality. The article says pollution has environmental and health consequences, but it does not identify specific illnesses, symptoms or long-term effects. This means the safest conclusion from the source is that harmful exposure poses a health risk.

Schools can reduce that exposure by controlling dust, improving classroom ventilation and preventing open burning on their premises. They can also encourage public transport and carpooling, which support lower vehicular emissions. Air purifiers are proposed in phases, beginning with 10,000 classrooms in government schools.

The plan is important because schools are places where children spend substantial time during the winter pollution period. Measures will run from October 2026 to February 2027. Anti-firecracker campaigns and air-pollution lessons are also intended to reduce pollution and encourage safer behaviour among students.

The measures work by targeting different pollution sources and exposure points. Sprinkling water in open areas helps control dust. More green patches support cleaner, greener school grounds. Efficient ventilation helps move and refresh indoor air, while public transport and carpooling can reduce the number of vehicles and emissions around schools.

For example, a school can water dusty open areas, stop dust-generating construction and improve classroom ventilation. It can then encourage students and staff to use buses or public transport. Recycling and reuse add another layer by reducing waste, while preventing open burning stops smoke from being produced on campus.

No single measure solves Delhi’s winter pollution problem. The Winter Action Plan combines them from October 2026 to February 2027. Schools must report progress monthly, and the government proposes phased air-purifier installation, beginning with 10,000 government-school classrooms.

Air pollutants are harmful substances or particles mixed into the air people breathe. Vehicles release emissions, construction creates dust, fires produce smoke and industrial activity adds pollution. The article identifies these sources, along with weather conditions, as contributors to Delhi’s worsening winter air quality. It does not name individual pollutants.

These sources can raise pollution around roads, construction sites, industrial areas and school campuses. People may then breathe more polluted air, while children face particular vulnerability. Schools can reduce nearby pollution by controlling dust, preventing open burning, avoiding dust-generating construction and encouraging public transport or carpooling.

The Winter Action Plan combines source control with indoor protection. Schools must improve ventilation, expand green patches and consider phased air-purifier installation. Awareness activities will explain pollution’s environmental and health consequences. The measures are scheduled for October 2026 through February 2027, with monthly progress reporting.
