(XI) Valuation
Methods based on Mass,
Energy and Area
|
- As an alternative system to the economic valuation.
- e.g. Material Flow Analysis, Material Intensity Per Unit Service, Ecological Footprint, etc.
|
- In general have not been used in SEA.
- However, ecological footprint has been considered as an valuation tools in the HK2030, and also as one of the sustainability indictors developed in SUSDEV21 to assess new proposals.
- This tool was finally not adopted as a lot of assumptions need to used to convert all affected activities into “area”, and it is more appropriate to serve as a tracking indicators to monitor the performance over time (with same set of assumptions), rather than as a tools to evaluate different proposals and alternatives.
