What is the Ozone Depletion Potential of HFC-134a refrigerant?

The correct answer is: 0

The Ozone Depletion Potential (ODP) of a substance measures its potential to contribute to the depletion of the ozone layer compared to a reference substance, typically CFC-11, which has an ODP of 1. HFC-134a, or 1,1,1,2-tetrafluoroethane, has an ODP of 0. This means that HFC-134a does not contribute to ozone layer depletion in a significant way, making it a preferred alternative to ozone-depleting substances like chlorofluorocarbons (CFCs). Understanding the implications of ODP is vital for environmentally friendly practices. The ODP value of 0 indicates that the use of HFC-134a in refrigeration and air conditioning systems does not harm the stratospheric ozone layer, aligning with environmental regulations designed to protect this critical resource. This is particularly important as industries transition away from substances that deplete the ozone layer, promoting the use of more environmentally benign options.
