Vietnam needs US$20 million to totally abandon ozone-depleting substances, hydro-chlorofluorocarbons (HCFCs), within the next 15-20 years, VnExpress quoted an official as saying Friday.
In its efforts to protect the ozone layer after signing the Montreal Protocol on Substances that Deplete the Ozone Layer in 1994, the country has removed 97 percent of ozone-depleting substances from production and use, Nguyen Khac Hieu, deputy chief the Hydro-Meteorological and Climate Change Department, said.
As of this January 1, Vietnam has totally gotten rid of 500 billion tons of chlorofluorocarbons (CFCs) often used in air conditioners and fridges, and 3.8 tons of halons usually used for fire and explosion protection. The country has also ceased the use of CTC --a major component in textile production.
However, Vietnamese businesses are currently still using HCFCs in producing air conditioners and fridges, because the recommended alternatives are simply too expensive, the news website said.
In addition, it takes such manufacturers businesses between 10-15 years to change over their technologies.
The news source quoted a statistic as saying that last year Vietnam used 3,300 tons of HCFCs, and the amount was expected to rise to 3,700 tons this year.
