There are several problems with a just-carbon-tax approach: 1) Carbon taxes just get passed on to the consumer. This makes them incredibly unpopular, because consumers see a short-term cost, but not a short-term benefit. In the US, this means that implementing a carbon tax is a good way to make sure you get voted out and replaced by a climate-denier in the next election. The Yellow Vests movement in France was sparked largely by a fuel tax. 2) Using a consumption tax also means that the poorest people of society pay the highest cost (relatively speaking.) It's unjust to make the poorest people pay the most, especially since they also do the least "damage." 3) According to the IPCC report, a carbon tax high enough to effect a rapid enough change would effectively be a fossil fuel ban anyway.
