What is the ODP value for R-134a?

Explanation:
ODP is a measure of how much a refrigerant can deplete the ozone layer in the stratosphere. R-134a is an HFC that contains no chlorine or bromine, so it doesn't release ozone-depleting halogens during use or breakdown. Because of that, its ODP value is zero. This is why it was adopted as a replacement for chlorine-containing refrigerants, though it does have a notable global warming potential, so newer options aim for zero ODP with lower GWPs.
