Ozone depletion substances (ODS) emission analysis from the life cycle of chemical substances and electricity used in potable water production in Malaysia
Malaysia is a country that is very committed in ensuring a constant development in a sustainable way by creating a balance between economy, social and environment. It can be proven as Malaysia is ranked in a very good position in Environmental Sustainability Index. But this ranking should be a guide...

Malaysia is a country that is very committed in ensuring a constant development in a sustainable way by creating a balance between economy, social and environment. It can be proven as Malaysia is ranked in a very good position in Environmental Sustainability Index. But this ranking should be a guideline to ensure the pockets of weaknesses in executing sustainable development in this country should be filled especially in effectively managing the environment. Ozone Depletion Substances (ODS) emission needed an environmental management method that is capable to identify the cause of this problem in order to the right action could be taken in place to mitigate the problem of ozone depletion. Event though drastic measures were taken in this country such as the ban of Halon gas use in fire control sector as a signatory to the Montreal Protocol 1989, it does not mean that this measure is enough to stop ODS from being emitted to the air. The use of Life Cycle Assessment (LCA) in a water treatment system proves that this method is capable to identify substances that emit ODS.
