How do you mean that? China would not produce iPads for the rest of the world if the rest of the world was not buying iPads, right? The graal of climate policy would actually be to be able to know precisely the impact of every single action we do. So that we could optimize properly. But because we can't do that, we have to rely on proxies, and that makes it error prone and practically very challenging.
