Yes, by itself these will not be enough. However, in Kyoto the international community agreed that there is a problem, in Paris the international community set (self imposed, not enough and non binding) targets for emissions. It will need several additional steps into the same direction to get a workable framework, and that will hopefully happen over the next decade. The (American) right will not like any of these steps, but they did not propose any alternative, it could have been possible to find market based solutions and respect national sovereignty more, or rely on the virtue of small communities etc., but these proposals were simply not developed.
