Well, that's the whole thing about environmental regulation. The problem is energy expenditure. Everything you do, down to breathing, expenses energy. Some things more. Some things less. A good proxy for energy is price. This is a heuristic of course, it's not perfect. So if you want to know what it would take to do good for the environment, imagine that you can only spend half as much on everything. Your backpack, your iPhone, ... everything. Not because you don't have the money, but because environmental regulation means you can't spend it like that. So only $20 restaurants. No iPhones, only cheap androids (no flagships) (or of course, if you like featurephones that's fine). No BMW 5-series or SUV, just a hatchback, and one of the smaller ones. And so on and so forth. If you want to regulate this, that means those products would simply become out of reach of the normal person. Not even because they don't have the money, but because it's forbidden for them to spend it like that.
