Delhi Fast-Tracks IIT Delhi’s Five-Year Real-Time Pollution Source Study

The move aims to give officials real-time data to trace sources for faster action during smog spikes.

Overview

  • Delhi’s environment minister, in a meeting Wednesday, ordered departments to fast-track approvals for a real-time source apportionment study.
  • IIT Delhi will lead the five-year program with a focus on PM10, complementing separate PM2.5 tracking by the Indian Institute of Tropical Meteorology.
  • The plan revives the Delhi Pollution Control Committee supersite and adds mobile vans and advanced sensors to follow pollution hotspots across the city.
  • A live dashboard will stream continuous readings with weekly briefs and monthly analyses to guide targeted responses by the DPCC.
  • Rollout remains in preparation, with seasonal hotspot sampling, an updated emission inventory, and upwind–downwind checks using IIT Delhi’s Sonipat site planned once equipment is deployed.
