Vehicle emissions testing
The Kerala State Pollution Control Board (KSPCB) is the authority tasked with enforcing laws related to protecting the environment in the state of Kerala. The board grants Consent NOCs and authorisation to industries and businesses, and also provides Pollution No Objection Certificates (NOC) for Red, Orange, and Green categories of industries.
To obtain a Pollution Control Board Certificate for your vehicle in Kerala, you must first visit an authorised emission testing centre. These centres can be found across Kerala and include petrol pumps, vehicle service centres, or standalone testing units.
At the testing centre, your vehicle will be connected to an emission testing device to analyse its exhaust gases. The test will measure carbon monoxide (CO), hydrocarbons (HC), and other pollutants, depending on the type of vehicle. For example, diesel vehicles are tested for the opacity of emissions, while compressed natural gas (CNG) and liquefied petroleum gas (LPG) vehicles are also measured for hydrocarbon and CO levels.
Once the test is complete, the readings will be compared to the permissible limits set by the Kerala Pollution Control Board. If your vehicle's emissions fall within the allowed range, it is considered compliant, and you will be issued a PUC certificate.
The cost of the test and certificate is reasonable, ranging from ₹60 to ₹100, depending on the vehicle type and testing centre. It is important to note that obtaining a PUC certificate is mandatory for valid car insurance in Kerala and helps promote environmental sustainability.
You can also download the Kerala Pollution Certificate online through the Vahan portal or the Kerala Pollution Control Board website by entering your vehicle's registration number, chassis number, or engine number.
