Expert Committee Report Uncovers Systemic Failures in Delhi-NCR Pollution Control Agencies
A comprehensive report by an expert committee constituted by the Commission for Air Quality Management (CAQM) has revealed significant operational deficiencies in the Delhi Pollution Control Committee (DPCC) and state pollution control boards across Haryana, Uttar Pradesh, and Rajasthan within the National Capital Region (NCR). The document, prepared following a Supreme Court directive, identifies critical gaps in staffing, monitoring infrastructure, data reliability, and enforcement mechanisms that are hampering effective air quality management.
Supreme Court Directive Spurs Investigation into Regulatory Functioning
The report, dated July 25 and recently shared publicly, was commissioned after the Supreme Court observed in May last year that it was necessary to examine the functioning of state pollution control boards and committees, which may be relying on outdated technology and equipment. The committee's findings call for a complete overhaul of anti-pollution regulators through the adoption of modern technology, regular calibration of monitoring stations, quality audits, and enhanced laboratory capabilities.
Air Quality Monitoring Networks Expand but Data Reliability Remains Questionable
While air quality monitoring networks have expanded across the region, the committee found that data reliability continues to be a major concern due to irregular calibration, auditing, and quality assurance of Continuous Ambient Air Quality Monitoring Stations (CAAQMS). The report specifically noted that out of 84 monitoring stations, most measure only six to eight out of the twelve parameters specified under the National Ambient Air Quality Standards.
The committee emphasized: "Data reliability in air quality monitoring is crucial for accurate calculations and assessments of ambient air quality. Therefore, there is a need to improve the data reliability of CAAQMS operated by CPCB, DPCC, IMD/IITM, HSPCB, UPPCB, MoHUA and RSPCB in NCR."
The report recommends that respective agencies ensure stations operate according to Central Pollution Control Board (CPCB) guidelines, with regular calibration, maintenance, and audit of CAAQMS, along with maintained online audit logbooks.
Technological Upgrades and Systematic Reforms Recommended
The committee proposed several key recommendations to address these deficiencies:
- Annual third-party performance audits of monitoring systems
- Implementation of artificial intelligence and machine learning tools for real-time data verification
- Establishment of an Air Quality Integrated Control and Command Centre with a GIS platform
- Creation of a dashboard displaying real-time Air Quality Index (AQI), air pollutant concentrations, meteorological parameters, and AQI forecasting with early warning systems
The report also highlighted persistent gaps in manual monitoring of ambient air quality in Delhi-NCR, noting that regular calibration and auditing of manual monitoring stations, as mandated by CPCB protocols, are not consistently conducted.
Expert Analysis: A Critical Roadmap for Clean Air Goals
Sunil Dahiya, founder and lead analyst at think tank Envirocatalysts, described the report as a critical roadmap that identifies the technological and institutional gaps hindering Delhi-NCR's clean air objectives. "By advocating for a transition towards systematic, aggressive emission load and activity tracking, it addresses the very core of effective air quality management," Dahiya stated.
He further commented: "As the report was finalized in July 2025, I hope its recommendations, ranging from AI-driven data verification to modernized industrial and vehicular monitoring, have already been adopted, with corrective measures now actively underway for ground implementation to ensure a data-driven and healthier future for the region."
The comprehensive assessment underscores the urgent need for technological modernization and systematic reforms within pollution control agencies to effectively combat the persistent air quality challenges facing India's capital region and its surrounding areas.
