The correct answers are C and D .

The audit team leader is responsible for leading and managing the audit process. This includes planning the audit and communicating with the auditee about audit arrangements and logistics , such as timing, site access, availability of personnel, audit schedule, and practical arrangements.

C. Communicating with the auditee regarding the logistics for the audit — Correct

The audit team leader normally acts as the main communication link between the audit team and the auditee during audit planning and execution. This includes confirming arrangements, audit timetable, opening and closing meetings, guides, access requirements, and other practical matters.

D. Planning the audit — Correct

The audit team leader is responsible for preparing the audit plan, coordinating audit team activities, assigning audit tasks, and ensuring the audit objectives, scope, and criteria are addressed.

The other options are incorrect:

A. Granting certification to the organisation being audited — Incorrect

Certification is granted by the certification body , not by the audit team leader. The audit team provides audit findings and conclusions, but it does not make the independent certification decision.

B. Evaluating the process established by the auditee to identify significant environmental aspects — Incorrect

This is an audit activity performed by the audit team as part of assessing ISO 14001 EMS conformity. It is not exclusive to the audit team leader.

E. Defining the duration of the audit — Incorrect

Audit duration is determined by the certification body or audit programme management using applicable certification rules, complexity, size, scope, risks, and environmental aspects. The audit team leader may work within the assigned duration but does not exclusively define it.

F. Sending the report to the accreditation body — Incorrect

The audit report is normally submitted to the certification body/client according to certification procedures. Accreditation bodies oversee certification bodies; they are not the routine recipient of every audit report from the audit team leader.

Therefore, the two exclusive audit team leader responsibilities are C and D .
