International Ozone Layer Protection Day approaching,Ozone layer facing the

challenge of Three refrigerant

January 23, 1995, the United Nations General Assembly decided on September 16 of

each year as the International Day for the Preservation of the Ozone Layer,  requires

all States Parties in accordance with the objectives of the Montrea l Protocol on Subs-

tances that Deplete the Ozone Layer and its amendments, to take concrete action  to

the occasion.

Fortunately, the depletion of the ozone layer can be stopped or even their own recov-

ery. To this end, the United Nations Environment Programme held various internation-

al conferences one after another since 1976, through a series of resolutions of the Pr- 

otection of the  Ozone Layer,  the restrictions and the phasing out of  ozone-depleting

chemicals worldwide.

"Montreal Protocol" (hereinafter referred to as "the Protocol") has basically reached its

wish, but still faces daunting challenges. "Said Rajendra Shende, UNEP OzonAction Br-

anch responsible person. Robin  Washburn,  senior policy analyst of the  New  Zealand

Ministry of Environment environmental issues that, if there is no the world  continuous

compliance, we will postpone to achieve this goal, or will lose this opportunity. "Parties

to the Protocol, in particular Article 5 (the provisions of the special circumstances of the

developing  countries) Parties involved in the future will be faced with new challenges.

Challenge: containing HCFC refrigerant Inventory "

The Rajendra analysis, the primary problem is that the threat of ozone-depleting subs-

tances, "inventory". Although the production of HCFC refrigerants have been eliminated

,but produced prior to 2010 containing HCFC refrigerant electrical equipment  (such  as

old refrigerators) is still running. These still exist in the world throughout the  electrical

equipment in ozone-depleting substances are referred to as "inventory".It is  estimated 

that if no action is taken, there will be the equivalent of 21 billion tons of carbon dioxide

emissions into the atmosphere.

Challenge: HCFC refrigerant production

Robin analysis of hydrochlorofluorocarbons (HCFCs), is the first challenge to determine

baseline levels. Protocol Article 5 Parties involved  consumption of  HCFCs in 2009  and

2010, data will be the baseline for future years. Only a few years later, in order to clear

the benchmark set is appropriate, If not, then you need to modify the method.

the consumption of HCFCs refrigerant will be decided in 2015 to achieve the degree of

difficulty of the target of 10% of the total phase-out of HCFCs. Limit the ability of HCF-

Cs industry growth will be continuing compliance with the Protocol, the key in the future'

Challenge: hydrofluorocarbon refrigerant alternatives greenhouse

Rajendra analysis, it is predicted that the use of alternative substances - HCFCs refrig-

erant refrigerant hydrofluorocarbons (HFCs), will increase rapidly.
