Delhi Air Pollution: CAG Report Exposes Systemic Failures – Key Findings and Recommendations for a Cleaner Tomorrow

The recent report by the Comptroller and Auditor General (CAG) on Delhi's efforts to combat air pollution has sparked widespread concern, revealing numerous lapses in pollution control measures that have exacerbated the city's environmental crisis. Delhi, known for being one of the most polluted cities globally, has faced significant challenges in managing air quality, particularly due to ineffective policies and inefficient infrastructure. Here are ten key findings from the CAG report that highlight the critical shortcomings in Delhi's pollution management strategy.

Introduction to the CAG Report

The CAG report, titled "Performance Audit of Prevention and Mitigation of Vehicular Air Pollution in Delhi," was recently presented to the Delhi Assembly, critiquing the previous government's approach to tackling air pollution, specifically focusing on vehicular emissions. The report outlines systemic failures in monitoring, enforcement, and public transport, which have hindered efforts to improve Delhi's air quality index (AQI).

10 Key Findings of the CAG Report

1. Inaccurate Air Quality Monitoring

• The locations of Delhi's Continuous Ambient Air Quality Monitoring Stations (CAAQMS) do not meet the Central Pollution Control Board (CPCB) standards, leading to potentially unreliable AQI readings[1][3].
• The inability to capture accurate data on pollutant concentrations, especially vital parameters like lead and benzene, undermines effective pollution control measures[1][5].

1. Public Transport Challenges

• The city faces a significant shortage of buses, with only 6,750 operational buses available, far below the required 11,000. This acute shortage forces citizens to rely on private vehicles, exacerbating pollution[4][5].
• The number of Gramin Sewa vehicles, which provide crucial last-mile connectivity, has remained stagnant at 6,153 since 2011, with many vehicles aging beyond ten years[1][4].

1. Irregularities in Pollution Under Control Certificates

• Over 22 lakh diesel vehicles had incomplete emission data during testing between 2015 and 2020. Moreover, 4,000 vehicles exceeded pollution limits yet received clearance certificates[2][4].
• Instances of issuing multiple certificates simultaneously, even within minutes, raise concerns about the credibility of the certification process[2][5].

1. Enforcement Gaps

• The transport department lacks adequate equipment and staff to enforce pollution norms effectively, leading to unchecked vehicular emissions[2][4].
• Inadequate monitoring at city entry points allows polluting vehicles to enter freely[2].

1. End-of-Life Vehicles

• Only 6.27% of end-of-life vehicles were deregistered between 2018 and 2021, leaving many polluting vehicles on the road[2][5].
• None of the 347 impounded vehicles were scrapped due to insufficient scrapping facilities[2].

1. Supreme Court Directives Not Implemented

• Despite court orders, Delhi has not set up Inter-State Bus Terminals (ISBTs) to restrict polluting inter-state buses from entering the city, contributing to vehicular pollution[2].

1. Mismanagement of Parking Funds

• There are no records of how parking fees were utilized, despite collections being made for infrastructure development[5].
• Unorganized parking leads to increased congestion and emissions[4][5].

1. Lack of Industrial Emission Monitoring

• Industrial units often operate without environmental clearances or adequate emission controls[3].
• This oversight exacerbates pollution levels, especially in industrial areas[3].

1. Health Implications of Persistent Pollution

• Delhi experienced hazardous air quality for 1,195 days between 2018 and 2023, posing serious health risks to residents[3].
• Fine particulate matter (PM2.5) exposure can lead to asthma, cardiovascular diseases, and reduced life expectancy[3].

1. Need for Comprehensive Interventions
   
   • Experts emphasize the need for stricter enforcement, reliable data, and expanded public transport to combat pollution effectively[3].
   • Recommendations include enhancing green spaces and enforcing waste management practices[3].

Challenges and Future Directions

The Role of Public Transport

The severe shortage of buses and inadequate last-mile connectivity have led citizens to favor private vehicles, significantly increasing vehicle emissions, a major contributor to air pollution. While measures like the odd-even scheme have been implemented, they were found ineffective due to exemptions for large segments of vehicles[4]. Increasing the fleet of operational buses, including electric or hybrid options, could offer relief by reducing private vehicle usage.

Real-Time Monitoring and Source-Specific Strategies

Improving air quality monitoring requires both accurate and real-time data. This would help policymakers develop source-specific strategies to tackle pollution from different sectors, such as industrial emissions and vehicular pollution. Inadequate monitoring systems currently hinder the ability to enact targeted interventions[1][3].

Political Commitment and Public Awareness

Political commitment to implementing pollution control measures is crucial. While there have been initiatives like smog towers and odd-even schemes, criticisms surround their effectiveness and proper execution[4]. Raising public awareness about the health risks of air pollution could also mobilize support for stringent pollution control measures.

Seasonal Challenges

Delhi's pollution worsens in winter due to meteorological factors and seasonal pollution sources like crop burning in neighboring states[3]. Addressing these external factors requires coordinated action with other states and more effective policies to curb local pollution during these periods.

Conclusion

The CAG report paints a stark picture of systemic failures in Delhi's pollution management, highlighting the need for immediate reform in monitoring, enforcement, and public transport systems. To combat Delhi's persistent air pollution crisis, it is crucial for policymakers to implement comprehensive strategies that address both local and external sources of pollution, ensuring a healthier environment for its residents. By enhancing pollution monitoring systems, expanding public transport, and enforcing strict pollution controls, Delhi can begin to overcome its status as one of the world's most polluted cities.

Recommended Actions for Delhi:

• Strengthen Air Quality Monitoring: Ensure all monitoring stations meet CPCB standards to provide reliable AQI data.
• Enhance Public Transport: Increase the number of buses and consider alternative modes like monorails or electric trolley buses.
• Enforce Pollution Standards: Implement regular emission tests, and ensure that PUCCs are issued only to compliant vehicles.
• Promote Sustainable Practices: Encourage green spaces and better waste management to reduce pollution sources.

By implementing these measures, Delhi can move towards a cleaner, healthier future for its residents.
