If the costs of carbon and climate change were fully internalized with appropriately set carbon taxes, I would agree with you. In the absence of that, it's entirely possible that these top down efforts are doing too much, too fast (although they could also be doing too little too slowly). But it's absolutely certain that in the absence of such taxes, the market itself will do it far too slowly. Now, as for what the "appropriately set carbon taxes are" (and therefore how fast is fast enough), that's an entirely political question that depends on the preferences and values of the society enacting the taxes.
