Regulatory frameworks often operate in silos, targeting specific pollutants without accounting for how they behave in different seasons. 2 min read May 8, 2026 06:15 AM IST First published on: May 8, 2026 at 06:15 AM IST Delhi’s air quality index shows that pollution levels have dipped with the onset of summer. That shouldn’t be a cause for complacency for policymakers. Analysis by the public-policy think tank Envirocatalysts underscores the need to continually monitor interactions between pollutants and meteorological conditions. Vehicular exhaust, construction dust, coal-based power generation, and waste-burning incidents do not change with the seasons. What changes, instead, is how these emissions behave once released into the atmosphere. In winter, temperature inversions and stagnant atmospheric conditions mean pollutants are trapped close to the ground, leading to high concentrations of particulate matter (PM).…
