An advisory panel to the Ministry of International Trade and Industry has announced that emissions of greenhouse gases such as hydrofluorocarbons and perfluorocarbons have yet to decrease in some areas.
The ministry's Chemical Product Council received a report on Tuesday stating that overall emissions of gases, including HFCs and PFCs, which were developed as alternatives to ozone-depleting chlorofluorocarbons, are declining, but that the amount of gases used in producing liquid crystal displays and sprays to dust computers has increased.
The panel heard from industries on voluntary efforts to reduce three greenhouse gases -- HFCs, PFCs and sulfur hexafluoride (SF6).
