CSE said that the PUC system, which is the only system to check emissions from on-road vehicles in India, is extremely weak in terms of lax norms, poor enforcement and poor quality test procedures.
New data from the Delhi Transport Department shows that failure rate is as dismal as 5 per cent - nearly all vehicles pass the test and there is no data on how many vehicles show up for test.
CSE said that the Supreme Court has recently given directions to the EPCA to audit all the 614 PUC stations.
"There are serious concerns over quality and credibility of PUC tests across the cities. A detailed audit that was carried out by the Central Pollution Control Board (CPCB) in 2013 in 76 PUC centres exposed serious anomalies, non compliance with the code of practice among others," it said.
The PUC system is not even designed to test tiny particles and NOx on road the key concerns from diesel vehicles. Volkswagen was caught cheating on NOx emissions, CSE said.
"The fact that India is totally unprepared to prevent emissions frauds and underperformance of emissions control systems on roads was proved a few years ago when the Tavera fraud case of General Motors was exposed," CSE said.
India has already specified more advanced On Board Diagnostic Systems in post-2013 vehicles. This should be integrated with vehicle inspection programme for more effective monitoring, the analysis said.
"India needs strong compliance regulations to make manufacturers responsible for on-road emissions performance for a vehicle's useful life on road.
"Consistent with the global best practices, India needs an independent authority to check emissions against standards, issue recall of vehicles by companies if they are found non-compliant, levy fines on defaulting companies and withdraw approval of sale if vehicles do not conform with the stated emissions targets," the analysis said.
CSE's review showed that currently, Indian certification agencies do not select vehicle samples for certification tests randomly and independently.
In fact, certification agencies give prior notice to manufacturers about the approximate time during which samples will be collected from a given lot which compromises independent and impartial testing, it said.
