What is the ODP of R-441a?

Explanation:
ODP measures how a substance would deplete the ozone layer, using CFC-11 as a reference (ODP = 1). R-441a is a modern refrigerant blend that contains no chlorine or bromine, so it does not participate in ozone destruction in the stratosphere. That means its ozone depletion potential is zero. Remember this is a separate consideration from global warming potential; even with zero ODP, the refrigerant can still have a notable GWP.
