SEA Methodologies and their Applications in Hong Kong

(V) Impact Pathway Approach
  • The analytical sequence “activities - emissions - dispersion – concentrations – impacts” are handled systematically.
  • Estimate how large a population is exposed to different concentrations of pollutants.
  • Traditionally a site-specific and time-specific approach and is data demanding.
  • Mostly applicable to conventional pollutants.


  • This approach is commonly applied in EIA in Hong Kong, and have been applied in a number of SEA, especially those with comprehensive studies, e.g. CTS-3 and Site Search for a New Power Station (by HEC).
  • Computer modeling (air quality and water quality), and wind tunnels are required to predict the concentrations of pollutants. For “points to note” in using computing modeling, please refer to “Applications in HK” column under Methodology (I) of the table.
