The SEEA Ecosystem Accounting (SEEA EA) constitutes an integrated and comprehensive statistical framework for organizing data about habitats and landscapes, measuring the ecosystem services, tracking changes in ecosystem assets, and linking this information to economic and other human activity. The United Nations Statistical Commission adopted the SEEA Ecosystem Accounting at its 52nd session in March 2021. The report of the Commission (subject to editing) can be found here. This adoption follows a comprehensive and inclusive process of detailed testing, consultation and revision. Today, ecosystem accounts have already been used to inform policy development in more than 34 countries -- [author website]. 1. Introduction -- 2. Principles of ecosystem accounting -- 3.
