If you're looking at refrigerants, the category that fluorocarbons would be in, then yes, ASHRAE is very much focused on investigating alternatives for lower global warming potential refrigerant options. Do we tax them? That would definitely be one way to influence behavioural change and how they're being consumed. There are a lot of active ways to motivate change through countries' commitments to supporting the Kigali agreement through the Montreal protocol. ASHRAE is very much engaged in those activities as well.
