ozoniloukkaavuuspotentiaali
Ozoniloukkaavuuspotentiaali (OPP) refers to the potential of a substance to cause damage to the ozone layer, which is a region of Earth's stratosphere that absorbs most of the Sun's UV radiation. Substances with a high OPP are known as ozone-depleting substances (ODS). The OPP of a substance is typically measured using the Ozone Depletion Potential (ODP) index, which compares the impact of a substance to that of chlorofluorocarbon-11 (CFC-11), a common ODS with an ODP of 1.0.
The Montreal Protocol, an international treaty, aims to protect the ozone layer by phasing out the production
Some common ODS with high OPP include CFCs, halons, carbon tetrachloride, and methyl chloroform. These substances
To mitigate the impact of ODS on the ozone layer, many countries have implemented regulations to phase
