Environmental Assessment

​Guidance on Environmental Assessment of Proposed Air Traffic Management Operational Changes


The purpose of Doc 10031 is to provide States, airport operators, air navigation service providers (ANSP) and other stakeholders with environmental assessment guidance to support decision making when analysing proposed air traffic management (ATM) operational changes. The guidance provides high-level environmental assessment principles intended to facilitate the use of a consistent approach for assessing the environmental impacts of operational changes.


ICAO has developed this dedicated web page where a variety of environmental assessment case studies are posted. The case studies demonstrate application of the Doc 10031 methodology. Readers are also invited to submit their own case studies via this web page. Case studies should be submitted using the form available here.
