The investigation by the Environment Protection (Prevent and Control) Authority (EPCA) has shown very poor level of compliance with the PUC programme — only 23% of vehicles turn up for PUC tests in Delhi. Global estimation shows that approximately 20% worst emitters on-road contribute nearly half of the pollution from all vehicles. State governments will have to audit all PUC centres and set up a strong oversight system to ensure credible tests. Moreover, the PUC programme will no longer be relevant for BS VI compliant vehicles to come in 2020. The automobile industry is already resisting the idea as they prefer tests in laboratory.
