## Key points

- Delhi’s winter air pollution returns despite repeated interventions.
- About 65% of its PM2.5 came from outside the city in winter 2025.
- Experts say coordinated, year-round action is needed.

## Summary

Delhi’s winter air pollution crisis continues despite years of government measures, emergency restrictions and public concern. The problem is predictable and its main sources are understood, but action has not produced lasting improvement, leaving residents to change their routines and rely on air purifiers as pollution worsens.

On Thursday, IQAir recorded an average PM2.5 concentration of 157.9 micrograms per cubic metre in Delhi, classed as “Very unhealthy”; the World Health Organization’s annual guideline is 5 micrograms. A 2026 assessment identified traffic, industry, dust, burning and pollution from neighbouring areas as major contributors. Analysis of government data for winter 2025 estimated that 65% of Delhi’s PM2.5 came from outside the city, making coordination across the wider National Capital Region essential. Environmentalist Sunil Dahiya says policy remains seasonal and reactive, while longer-term steps such as cleaner fuels, stronger enforcement and expanded public transport are slow to materialise.
