How much ozone is being destroyed by 15000kg of aluminum oxide vapor? Is it a meaningful amount? On the scale of the Earth, my completely uninformed intuition

How much ozone is being destroyed by 15000kg of aluminum oxide vapor? Is it a meaningful amount? On the scale of the Earth, my completely uninformed intuition is that 15k kg of alumina doesn't feel that significant. I'd guess that rocket production and launch emissions are way more harmful. But don't know.
