Environmental Impact Assessment

A major part of the three-runway system project is the Environmental Impact Assessment (EIA), which includes a series of studies assessing the potential environmental impact of the project across 12 key aspects. The studies were undertaken by a strong EIA Study Team, comprising an experienced lead EIA consultant, a review consultant and a number of reputable experts, both local and overseas.

Airport Authority Hong Kong (AA) is committed to fulfilling all the commitments made in the EIA Report and subsequent conditions and requirements. The EIA includes over 250 mitigation measures to address and mitigate potential environmental impacts across 12 environmental aspects.

A dedicated website,, has been set up for reporting the environmental monitoring and audit data and other relevant information about the three-runway system (3RS) project.
