Delhi pollution: GRAP-IV flags polluters, but gaps in emission testing cloud true picture

Delhi’s environment minister revealed over 10,000 vehicles failed emission tests under GRAP-4, with 2 lakh receiving PUC certificates after the ‘No PUC, No Fuel’ rule. The government is upgrading testing centers and introducing third-party inspections for accuracy and transparency. Experts, however, highlight current tests’ limitations, advocating for mileage and maintenance in certification.
