Waste and air quality
Open Burning
Definition
Open burning is the combustion of unwanted materials — household and municipal waste, agricultural residues, or debris — in the open air or in open dumps, without emissions controls. It releases particulate matter, dioxins, furans, black carbon and greenhouse gases, and is practised widely where waste collection and disposal systems are inadequate.

Overview
What it means
Burning waste in the open is among the most polluting disposal methods: low combustion temperatures generate highly toxic products, and the practice is a leading source of dioxins globally. Agricultural residue burning additionally drives severe seasonal smog in regions such as South Asia.
How it is used
The term appears in waste management policy, air quality regulation and climate mitigation; the Stockholm Convention addresses open burning as a source of unintentional persistent organic pollutants, and many jurisdictions ban the practice.
Why it matters
Open burning links waste governance failures directly to public health damage and near-term climate forcing through black carbon, making it a priority target in both pollution and climate agendas.
