Under normal operation, in a perfect system it will stay sealed. Problems come at end of life and in real world use. Seals aren't perfect, gas escapes slowly. Some seals are bad, a blast chiller at my work needs regassing every other year. People dump old fridges and freezers on the street and they get damaged.
It all gets out eventually.
Yes, but the amount of gas in an AC system is insignifcant compared to the CO2 generated just making the AC system in the first place. Hell, delivering it probably generated significantly more pollution. Not saying we shouldn't strive to make it better, but it's not as actively harmful as it was 30+ years ago.
