Going GreenWhere do we stand ?

Energy Per Capita in ASEAN

The Star 11 Dec 2008Sweden cleanest, S. Arabia dirtiest, Malaysia bottom 10: climate index

POZNAN (AFP) Sweden does the most of any country for tackling emissions of greenhouse gases, while Saudi Arabia does the least, according to a barometer published on Wednesday by watchdogs at the UN climate talks here.The groups categorised dangerous climate change as an increase in temperature beyond two degrees Celsius (3.6 Fahrenheit) over pre-industrial levels.

Sweden's fourth place was followed by Germany, France, India, Brazil, Britain and Denmark.

The bottom 10 were listed in descending order as Greece, Malaysia, Cyprus, Russia, Australia, Kazakhstan, Luxembourg, the United States, Canada and Saudi Arabia.

So how do we go about achieving a

GREEN BUILDING ?

A Green or Sustainable building is designed:

To save energy and resources, recycle materials and minimise the emission of toxic substances throughout its life cycle,

To harmonise with the local climate, traditions, culture and the surrounding environment, and

To be able to sustain and improve the quality of human life while maintaining the capacity of the ecosystem at the local and global levels

Green buildings have many benefits, such as better use of building resources, significant operational savings, and increased workplace productivity

Building green sends the right message about a company or organization - its well run, responsible, and committed to the future
