The Public Accounts Committee (PAC) has criticised the Delhi government for persistent gaps in air pollution monitoring and for shortcomings in public transport services. The committee pointed to insufficient spatial coverage of monitoring stations across the city, delays in maintenance and calibration of instruments, and irregularities in data transmission that undermine the reliability of air quality assessments. It asked the government to prepare a comprehensive corrective action plan with clear timelines and to strengthen coordination among the agencies responsible for environment, health and urban transport.

The PAC said the current network of fixed monitors did not capture hotspots in several dense neighbourhoods and recommended the deployment of additional portable units to cover vulnerable localities. It also suggested instituting regular third party audits, publishing station level data in accessible formats, and investing in training for technical staff to ensure consistent quality checks. The committee noted that greater transparency would allow researchers, civic groups and residents to better understand pollution trends and to support evidence based interventions.

On transport, the PAC highlighted that gaps in bus frequency, inadequate maintenance of the fleet and poor last mile connectivity constrained the attractiveness of public transport for daily commuters. The committee recommended a review of route rationalisation, more frequent services during peak hours, and improvements in interchange facilities to reduce waiting times and to make journeys more seamless. It urged prioritising investment in low emission buses and in systems that provide real time passenger information so that commuters can make informed choices.

The PAC demanded that the government present progress reports and costed proposals within a set timeframe so that remedial steps can be tracked and accountability established. It said future releases of funds should be linked to measurable improvements and that follow up hearings would assess implementation. The committee recommended close collaboration with central authorities and municipal corporations to ensure a coordinated approach to pollution control and to urban mobility planning.
