"This document discusses how the six evaluation criteria of the OECD DAC (Organization for Economic Co-Operation and Development – Development Assistance Committee) can be used to get environmental sustainability on the agenda for evaluations and monitoring. These criteria are widely used in international development organisations, and similar criteria are often used in other organisations. This document is based on existing guidance produced by OECD DAC (OECD, 2021) with additional commentary from the members of the Footprint Evaluation Initiative." (Summary, page 1)
