Calibration according to ISO 14001:2015

Answer:

The standard does not define who will perform the calibration and what qualifications must the person to perform calibration have. It simply says in the clause 9.1 "The organization shall ensure that calibrated or verified monitoring and measurement equipment is used and maintained, as appropriate". However, the clause 7.2 states "The organization shall determine the necessary competence of person(s) doing work under its control that affects its
environmental performance and its ability to fulfil its compliance obligations".

This means that in case of internal calibration, the company itself may define requirements for competence of perople performing the calibration. If the company decides that no certificate is needed, than the person does no t need the certificate.
