The air we breathe still defines how we live, work and move. As winter sets in for 2026, Delhi is already experiencing very poor air quality. Despite years of promises, the city’s skies remain hazy with fine particles (PM2.5) that are linked to heart disease, lung infections and thousands of premature deaths every year. The question now is simple: Will this year be different or are authorities just recycling the same solutions?

India’s National Clean Air Programme (NCAP) aimed to cut fine particulate pollution by 40 per cent by 2026. In some cities there have been improvements, but many still struggle to break free from seasonal smog cycles. Delhi’s AQI regularly dips into “very poor” or “severe” levels each winter and nearby towns show similar patterns. This shows that deep structural changes are still missing.

Air pollution is not just about the weather or crop fires. Vehicles, construction dust, industry emissions and even everyday activities like open waste burning contribute to toxic air. Many experts argue that air pollution is a year-round problem, which becomes more apparent in winter.
