REREQUISITES
For designated project (DP) as specified under the Environmental Impact
Assessment Ordinance (EIAO), Environmental Permit shall be obtained
by following the statutory Environmental Impact Assessment Process,

C
REDIT REQUIREMENT
One Bonus credit from SA 5 Ecological Impact can be achieved through
the following:
Having a site which scores less than 20% of the points in the Habitat
Section of The Nature Conservation Policy - 2009[1] and having a site
which scores less than 30% in the Biodiversity Section of The Nature
Conservation Policy - 2009; or
Demonstrating that appropriate design measures have been
implemented to contribute positively to the ecological value of the site.

SSESSMENT
To obtain a proper balance between building development needs and
unacceptable damage to the natural environment, the ETWB of the
HKSAR Government introduced a revised scoring scheme for assessing
the ecological value of a site, called Nature Conservation Policy - 2009.
This is a relatively objective and systematic method of assessing the
ecological importance and value of individual site by taking into accounts
the value of the particular habitats and biodiversity.
This indicator is particular applicable for Greenfield site building
development. The assessment scheme facilitates the identification of the
entire site or particular portion of the site that deserve better protection
and their relative priorities for action.
There are 2 portions in the Nature Conservation Policy, which are
Habitat and Biodiversity. Lower percentage obtained in the Habitat
section means the building is designed on a Brownfield site, which has
low habitat value. The major Sub-criteria in this indicator are:
Naturalness (weighting 15%)
Habitat diversity (weighting 15%)
Non-recreatability (weighting 10%)
A lower percentage obtained in the Biodiversity section means the
building is designed on a Brownfield site, which has a low biodiversity
value. The major Sub-criteria in this indicator are:
Species diversity & Richness (weighting 30%)
Species rarity / Endemism (weighting 30%)
Survey of the site-wide ecological value is required in order to ensure the
preventive measures and the following detailed design work will take full
consideration of the existing sites’ ecological conditions.
