A PUC certificate stands for "Pollution Under Control Certificate" and is a mandatory document for every vehicle owner in India. It is a document that states that the emissions from a vehicle are compliant with the environmental standards established by the government. The certificate is issued by authorized emission testing centers across the country after a thorough examination of the vehicles exhaust gas. The PUC certificate is as important as a registration certificate, driving license, and insurance policy. It is an effort to reduce pollution overall and to ensure that all vehicles’ emissions are under a controllable limit and are not above the legally mandated limit that has been prescribed. The certificate confirms the percentage of carbon emission, that is, the amount of pollution. The PUC certificate is valid for six months for new vehicles. Vehicle owners can get their vehicles PUC tested at any petrol pump or independent PUC testing center in their vicinity.
