Delhi’s air quality has plunged to alarming levels, with the Air Quality Index (AQI) soaring to a hazardous 764 in November, a stark contrast to Beijing’s peak of 236 during the same period. While both cities are bustling economic hubs with vast populations, the difference in air quality is dramatic. Delhi’s AQI has historically reached extreme highs, sometimes exceeding 1000, while Beijing’s annual average AQI is significantly lower. This persistent smog, characterized by dangerous PM2.5 and PM10 particles, poses severe health risks, contributing to respiratory illnesses, cardiovascular diseases, and even premature death. Factors like vehicle emissions, industrial activity, construction dust, and agricultural stubble burning exacerbate the problem, particularly between October and February. India tragically leads global pollution rankings, with many of its cities among the most polluted worldwide. To combat this crisis, Delhi can draw inspiration from Beijing’s decade-long “war on pollution.” This comprehensive approach involved stringent regulations, massive investments in cleaner technologies, and regional cooperation. Beijing successfully phased out coal power plants, promoted electric vehicles, and expanded public transportation. They also implemented a sophisticated network of air sensors for real-time monitoring and fostered data transparency to boost public awareness. Crucially, Beijing collaborated with neighboring regions to tackle transboundary pollution, manage construction dust, and implement afforestation programs. This multi-pronged strategy led to a significant reduction in PM2.5 levels and a dramatic increase in good air days. Delhi has implemented various temporary measures, including vehicle restrictions, bans on firecrackers, and public awareness campaigns via the ‘Green Delhi’ app. Plans for increasing CNG buses, promoting EVs, and developing green corridors with extensive tree planting are underway. However, the urgency cannot be overstated. Sustained, stringent, and coordinated action, mirroring Beijing’s success, is essential for Delhi to shed its reputation as one of the world’s most polluted capitals and safeguard the health of its citizens.
