The mandate for conducting, coordinating and overseeing evaluation in UNEP is vested in the Evaluation Office as described in the Evaluation Policy.

This mandate covers all programmes and projects of the Environment Fund, related trust funds, earmarked contributions and projects implemented by UNEP under the Global Environment Facility (GEF). The Office reports directly to the Executive Director but works independently from the substantive programmatic divisions.

The Evaluation Office conducts various types of evaluations and management studies, in accordance with the requirements of the United Nations General Assembly, the UNEP Governing Council, and the Norms and Standards for evaluation of the United Nations system.

Activities include; in-depth sub-programme and project evaluations, evaluations of expected accomplishments, project supervision reviews and management studies. The Office provides technical backstopping to project and programme managers in undertaking project reviews when requested and closely follows up on the implementation of evaluation recommendations.

The Office prepares Special Studies designed to provide decision making information and improve evaluation processes, and procedures. Guidelines and practical approaches for conducting evaluations are elaborated in the UNEP Evaluation Manual.
