NEW DELHI: The Commission for Air Quality Management (CAQM) told the Supreme Court on Wednesday that vehicular pollution is the highest contributor to air pollution in Delhi-NCR and recommended 15 long-term measures to improve the worsening Air Quality Index (AQI).
Appearing for CAQM, Additional Solicitor General Aishwarya Bhati told a bench comprising Chief Justice of India Surya Kant and Justices Joymalya Bagchi and Vipul M Pancholi that a meta-analysis of studies from 2015 to 2025 attributes PM2.5 in Delhi to a mix of primary emissions and secondary particulate formation from sources within the National Capital Region (NCR).
The CAQM recommended the following measures to be introduced in a phased manner:
- Time bound phasing out of polluted vehicles from Delhi-NCR based on emission potential.
