We also need taxing of emissions to curb emissions of other greenhouse gases (mostly methane) that are not tied directly to the burning of fossil fuels. For example emissions from household animals, drained farmland and so on.
The problem with these kinds of taxation systems is that they are really difficult to enforce, because you need a way to measure the amount of greenhouse gas emitted by each individual business.
Taxation of emissions is another tool in the toolbox, but we also need to guarantee that the consumption of fossil fuels is decreasing at the same time. Taxation may help, but it provides no guarantee of that.
