CAG report on pollution flags flaws in AQI data, PUC certificate system, Pg 2

Key Highlights

Flaws in AQI Monitoring

• Air Quality Index (AQI) data in Delhi termed unreliable due to incomplete and inadequate data.
• AQI was calculated with less than 16 hours of required monitoring, violating CPCB norms.
• DPCC failed to measure lead levels and ensure functional air quality stations.

Issues with PUC Certification

• Over 1.08 lakh vehicles exceeding emission limits still received PUC certificates.
• Multiple certificates issued to vehicles simultaneously or within minutes.
• From 2015 to 2020, ~4,000 vehicles violated norms but still got certified.
• Lack of inspection and third-party audits in PUC centres highlighted.

Vehicle Scrapping & Policy Failure

• Only 2.98 lakh (6.27%) of overage vehicles were de-registered.
• Not a single one of 347 impounded vehicles scrapped by March 2021.
• Scrapping infrastructure severely lackingcan handle only 4,000 vehicles vs 41 lakh awaiting scrapping.

Unutilized Transport Alternatives

• Despite budgetary provisions, no progress on monorail/trolleybus projects.
• Two new ISBTs still unconstructed despite SC directions from 1998.

Political Reactions

• AAP government accused of compromising public health via inaction.
• AAP leaders defended their environmental record, claiming proactive measures.

Analysis & Way Forward

• The report reveals serious implementation lapses in pollution control policies.
• Urgent need for transparent data systems, real-time AQI compliance, and digital monitoring of PUC issuance.
• Vehicle scrapping capacity must be scaled up with regulatory enforcement.
