Delhi's Air Cleanest in 5 Years, But Still 19x Worse Than WHO Standards

• Delhi recorded its cleanest air in five years, with PM2.5 levels at 98 micrograms/cubic meter in 2025, matching 2020 levels.
• Despite improvement, current PM2.5 is 2.45 times the national standard and nearly 19.6 times the WHO safety standard.
• PM10 levels in 2025 were 200 micrograms/cubic meter, 3.3 times the national and 13.33 times the WHO standard.
• Cleaner air attributed to increased rainfall, early Diwali, reduced stubble burning, and continuous strong winds.
• Experts warn that consistently high pollution indicates emissions far exceed Delhi-NCR's capacity, urging detailed control measures.

Why It Matters: Delhi's air improved to 2020 levels but remains dangerously polluted, far exceeding global safety standards.
