What is polluting Delhi’s air?: understanding uncertainties in emissions inventories
Fixing Delhi's air quality requires a deep understanding of the sources that contribute to air pollution. Despite multiple source apportionment studies specific to Delhi NCR, policymakers can’t design an effective action plan due to varying estimates. This study brings clarity on the existent discrepancies and attempts to understand the gaps and opportunities to develop emissions inventory for source apportionment studies. The study focuses on five emission inventory studies on Delhi NCR. It draws comparisons between emissions inventories for ten sources of air pollution for PM 10 and PM 2.5.
