To periodically verify that the EMS is operating effectively as intended, internal and external audits are conducted. Compliance with regulatory requirements is verified through routine and periodic inspections, and operational evaluation. Internal EMS audits are conducted by a pool of more than 100 environmental auditors who are conversant with ISO 14001 auditing skills. In addition to internal audits, we also invite an independent external certification body to conduct ISO 14001 surveillance audits and further ensure our compliance with international standards. This audit mechanism is designed to ensure that any non-conformance is regularly identified and addressed.
