So I have to say I'm sceptical about claims that it's unpredictable. The whole point is predictability, because we're actually saying over a 30-year time horizon, here is the phase-out rate. Up until this point, all it's saying is, "Well, there's a kind of sword of Damocles, which is we may phase these things out at some point, but we're not going to give you the ability to plan for that because we're not actually signposting in advance what it is."; whereas what this bill does is it actually signposts over a three-decade time horizon what that looks like.
