The Protocol explicitly aimed at phasing-out substances such as chlorofluorocarbons (CFCs) – found in products such as refrigerators, foams, and hairsprays – in order to repair the thin gassy-shield that filters out the sun’s harmful, ultra-violet rays. By 2010, close to 100 ozone-depleting substances, including CFCs, will have been phased-out globally.
该议定书明确要求逐步减少诸如氟利昂（CFCs）这类物质的使用——这类物质通常存在于冰箱，塑料泡沫和头发定型水当中——以修补过滤阳光中有害紫外线的薄薄臭氧层。到2010年时，将有近100种类似氟利昂这类的破坏臭氧层物质在全球范围内遭到淘汰。
