This set of gases was developed because they don’t deplete the ozone so much, but they’re incredibly potent greenhouse gases, which is why there’s an effort to end their use.
Right. One issue is that the US’s glidepath towards low GWP includes significant HFO usage (which is a PFAS) rather than speedrunning natural refrigerants which are the only sustainable long term solution. So we’ll likely have more warming, but less PFAS as a result of this, along with higher costs and more uncertainty. The focus needs to be on natural refrigerants though long term.
