ABSTRACT: Background: Delhi's air quality is, by any measure, a serious and ongoing crisis. The city consistently records some of the worst Air Quality Index (AQI) levels in the world — worse than much larger industrial cities in China, and worse than cities currently experiencing armed conflict, such as Iran. This paper investigates the structural and policy reasons behind the persistence of Delhi's air pollution problem despite decades of regulatory intervention. Methodology/Principal Findings: Drawing on a systematic review of policy documents, judicial records, emission inventories, and published scientific literature, the paper identifies the principal emission sources — vehicle traffic, industrial activity, poor waste management, crop residue burning in neighbouring states, and geography-driven temperature inversions — and evaluates the effectiveness of interventions including judicial mandates, vehicle fuel conversion programmes, forecasting systems, and agricultural residue management schemes. The central finding is that government responses have almost always been reactive and short-term, addressing symptoms rather than root causes. The 2009 Punjab Preservation of Subsoil Water Act is identified as an underappreciated driver of concentrated stubble-burning episodes. Court-mandated measures such as smog towers are found to lack scientific justification at the scale required, while the diesel-to-CNG conversion stands out as a genuinely effective structural intervention. Conclusions/Significance: Real improvement requires committing to long-term, source-specific, and regionally coordinated strategies. Immediate priorities include updating emission inventories (last comprehensively revised in 2016–17), expanding the ambient monitoring network to at least 100 stations across Delhi's airshed, and diversifying agricultural cropping patterns in Punjab and Haryana away from the rice-wheat monoculture that drives annual burning episodes.
