(III) Environmentally Extended
Input / Output Analysis (IOA)
  • IOA is traditionally an analytical tool within economics and systems of national account.
  • IOA can be applied to include environmental impacts by adding emission coefficients to the monetary IOAs.


  • In general, IOA has not been applied in SEA in Hong Kong.
  • However, a related approach is adopted in the SEA for the RDS-2 where the economic aspects of the environmental benefits and impacts of road vs. rail have been compared to present the whole picture of benefits and impacts borne by the community.
