Delhi's air quality worsens as winter haze approaches

Delhi's air-quality index has risen steadily over the last week, reaching 151 (moderate) on Wednesday after readings of 118, 160, 169 and 178 on earlier days. The increase aligns with reduced rainfall and hot, humid weather as the city transitions to the post-monsoon season. Officials warned that dispersion conditions will worsen, triggering a permanent winter-pollution framework effective from November 1 to February 28, which mandates construction bans, 50% office attendance, higher parking fees and mandatory vehicle emission certificates.

Although ₹100 crore has been earmarked for more than 300 truck-mounted anti-smog guns, procurement has only just begun, and road-paving projects slated for completion by November 30 are still pending, fueling dust emissions. The Municipal Corporation's barrier-free tolling at major entry points is also delayed. The degree to which these actions are completed before winter will determine how much of the announced plan can be enforced when pollution levels rise.
