Guidance for Implementing the Impact Assessment Follow-Up International Best Practice Principles
March 2024

Following up on impact assessments (IA) is essential to ensure that projects and plans meet their environmental, social, and economic commitments.
This guidance document supports IA practitioners in implementing the Impact Assessment Follow-up International Best Practice Principles published by IAIA. It provides additional insights into their practical application without modifying the original principles, which are reproduced in Appendix A.
The original Best Practice Principles document defines IA follow-up, outlines objectives for IA follow-up, and explains what it entails with respect to the five key elements of monitoring, evaluation, management, engagement and communication, and governance. It then briefly explains 15 best practice principles.
This guidance document helps IA practitioners apply best practices by providing clear steps on how to monitor, evaluate, manage, and communicate IA follow-up effectively.
This resource is valuable for policymakers, project developers, regulators, and communities working to strengthen IA follow-up processes.
