Consensus on a carbon tax that is consistent with the marginal cost of abatement and staying below 2C is $50 or so per tonne by the late 2020s and up to $180 by 2050 to get all the way to net zero. The idea is that you set a tax that goes up predictably so that you incentivise capital decisions leading to emissions reductions over the life of the capital asset.

That might seem like a lot but based on US average consumption based emissions (production based emissions taxation is for chumps) that's $850 annually by the late 2020s. Of course, all or most of that can be returned to people through other tax reductions. I can't be the only one who looks at that number and thinks, "Is that fucking it? Jesus, just do it then."
