The IEO organized a session on Approaches and Methods to Climate Change and Environmental Evaluations at the Evaluation Symposium organized by the Islamic Development Bank.

The United Nations Evaluation Group (UNEG) on Environment and Social Impact Assessment and the Global Environment Facility (GEF) Independent Evaluation Office held an Evaluation Practice Exchange (EPE) session on "Integrating Environment into Evaluations".

The book explores why the Global Environment Facility (GEF) invests in evaluation for accountability and learning to inform its decision making on programming priorities, and how this leads to wiser funding decisions and better program performance on the ground. No other multilateral development or environment agency places evaluation fully at the center of their decision making.

The GEF Independent Evaluation Office (GEF IEO) and the Earth-Eval community of practice organized a webinar on the book Environmental Evaluation and Global Development Institutions: A Case Study of the Global Environment Facility (GEF). The panel moderated by Juha I Uitto, Director of the GEF IEO, reflected on how to make evaluation count for international environmental action.

The GEF Independent Evaluation Office, the Environmental Law Institute and the World Bank held a webinar on Lessons from an Evaluation of the GEF's Interventions in Fragile and Conflict-Affected Situations. The event was part of the gLOCAL Evaluation Week 2021.
