Several Pollution Under Control (PUC) centers in Noida, India, are issuing rigged PUC certificates to vehicle owners for an extra fee of Rs 50 or Rs 100. Operators manipulate emission test results and provide fake certificates that appear authentic in online records. This corruption compromises efforts to reduce pollution levels and undermines scientific measures such as the graded response action plan. Authorities have promised to crack down on these centers and cancel the licenses of violators.
