Pollution from winter waste burning in cities three times higher than summer, study finds
Winter brings weaker winds, more stable atmospheric conditions and, in many places, temperature inversions that restrict the dispersion of pollutants; the World Resources Institute India study also attributes increased waste burning partly to its use for warmth, alongside seasonal waste disposal practices

Context
A working paper by the (WRI) India reveals that open waste burning in Indian cities is up to three times higher in winter than in summer. The study highlights socio-economic disparities in waste management, noting that poorer areas, particularly in Tier 2 cities, experience the highest incidence of burning. This coincides with efforts by the to curb such practices in the ahead of the winter season.
UPSC Perspectives
Environmental
The WRI study emphasizes the localized impact of open waste burning. While contributing less than 1% to overall citywide PM2.5 and PM10 emissions, its proximity to residential areas significantly increases short-term exposure to toxic smoke, posing severe health risks. This is exacerbated by winter meteorological conditions, specifically temperature inversions (where a layer of warm air traps cooler air near the surface) and stagnant winds, which hinder the dispersion of pollutants. The burning of paper and plastics releases toxic compounds like dioxins and furans. UPSC aspirants should connect this to the broader issue of winter smog in northern India and the role of the (NCAP) in mitigating particulate matter pollution.
Governance
The study exposes systemic flaws in municipal solid waste management, linking the incidence of burning directly to disparities in service delivery. The higher frequency of burning in poorer neighborhoods suggests inadequate waste collection infrastructure and enforcement in marginalized areas. The mandate local bodies to collect and process waste scientifically, explicitly prohibiting open burning. The intervention by the (CAQM)—a statutory body formed under the —highlights the need for a multi-pronged approach involving strict enforcement (zero-tolerance policy), infrastructure augmentation, and worker welfare (providing alternatives to burning waste for warmth). This underscores the challenge of implementing national policies at the local level.
Social
The report highlights a clear socio-economic divide, or environmental injustice, where lower-income populations bear a disproportionate burden of air pollution due to inadequate municipal services. The burning of waste in these areas is often driven by necessity—either due to a lack of collection services or for warmth during winter. This directly impacts the right to a clean environment, interpreted under (Right to Life) of the Constitution. For UPSC Mains, this illustrates the intersection of urban poverty, unequal resource distribution, and public health, necessitating policies that prioritize equitable service delivery and address the root causes of informal waste disposal practices.
