2SUSTAINABLE DEV. POLICIES & PRACTICES

Minimize ecological footprints

Eliminate all forms of wastage

Optimize energy efficiencies & switch to renewables

Efficient, clean & affordable transport

Organic farming

Clean technologies [poll. prevention] as well as LCA assessments

Public participation, accountability & transparency

Eliminate hazardous wastes & products

REDUCE GHG EMISSIONS

3SOME SUSTAINABILITY INITIATIVES

Design & construction of Energy Efficient & cool buildings

Retrofitting of existing buildings

Integration of good mobility in new towns

Improvement of public transport in Klang Valley

Organic Farming Energy conservation

after audits Better Landscaping &

adequate green lungs Biodiversity

conservation esp. in nature parks

Proposed comprehensive Nat. Energy Policy

Idea is to keep the cool air in & hot air out (of & from the house)..

SUSTAINABLE ENERGY USAGE

Contributes to reduction of GHG emissions as overall energy usage is curbed;

Should also affect the usage of construction material that has a low carbon footprint & if possible low transport-miles;

Accelerate the greening of the supply chain from the manufacturers up to final use.

22

SUSTAINABILITY OPPORTUNITIES for Const. Sector Comply with ISO14000

stds. Esp. dealing with EP & LCA;

Try to achieve energy efficiency levels of MS1525 for office buildings;

Comply with occup health levels in OSHA;

Demonstrate Care for the Environment

Monitor env conditions during construction & in vicinity of work sites;

Ensure construction waste is minimal & re-use as much as possible;

Avoid open-burning & illegal dumping;

23

SUST. OPPS. [ctd] Observe diligently env

mgmt plans, whenever they exist or develop on own initiative;

Be responsive to any complaints from workers or occupants /residents of neighbourhood;

Insist on vendors / suppliers observing good env practices;

Publish detailed CSR reports & ensure adequate distribution;

Take pride in environmental performance & care!

24

The Malaysian Scene

25

Developers & civil engineers just refuse to build along contours. Their levelling craze is worsened by the unwillingness to protect bare soil. Hence the ever common

EROSION & SILTING-UP of drains & rivers

26

WHERE ARE THE WORKING SILT-TRAPS?

Can anyone name a specific site where soil erosion is prevented? Where silt-traps are adequate in nos & fully maintained?

Do developers/ constructors fully compensate the community for damage caused by resulting floods?

Are do they just pass the buck to someone else?

27

DO CONSTRUCTORS PROVIDE

Adequate & safe transport facilities for their staff?

Enough accommodation for their site workers? Satisfactory slope protection and environment-

friendly drainage systems at sites? Enough protection to staff & passerbys at their

sites?

END 28

DO MALAYSIAN ENTITIES CARE?

Not many vie for the Hibiscus Award

How many winners have sustained their efforts?

CSR reports are NOT the norm

Financial institutions virtually ignore people & environment [with a couple of exceptions]

Support is more forthcoming for GREEN rather than BROWN issues

Only project rather than programme funding for env. NGOs

Little public disclosure instead confidentiality invoked !
