As a signatory of Montreal Protocoll and of its amendments the Czech R
epublic accepted pertinent legislation (Law Nr 86 - 1995) which includ
es the regulating rules for the production and consumption of substanc
es depleting the ozone layer. These are comparable to the above-mentio
ned international documents. In the years between 1986 and 1996 the pr
oduction and consumption of fully halogenated chlorofluorohydrocarbons
(CFC), of tetrachlormethane and methylchloroform was lowered in accor
dance with the protocoll resulting finally in their full exclusion. In
addition to other branches of economy a considerable activity could b
e also observed in the chemical industry in searching for subtitutes o
f propelling gases in aerosol products and in preparing capacities for
regeneration and recyclization of applied refrigerating media.
