How do you do this, without hurting people with 'clunkers' who need said 'clunker' to get to work or the market (because they live in a food desert), and can't really afford to upgrade to greener living because cost of living takes their whole paycheck, and they'd be homeless if they can't afford gas or their car breaks down unless they just started living out of their car? I'm hesitant to think taxing gas at the pump makes any sense, I think maybe taxing diesel though could be a better thing because diesel is used more commercially by big rigs, which is a tax on commercial industries rather than consumers. Jet Fuel and such should have a very high tax, because that's something most people don't use, and isn't really a 'necessity'. Fuel at ports should also be taxed, and I think ports/airports should be under some global climate action 'congress' or something that ensures equal taxation and carbon offsets globally are being applied. Though, if we were to use all the tax revenue or at least maybe 50% for UBI to say anyone with < 100k annual salary, I think it wouldn't matter if we taxed everything more evenly including gas at the pump, in fact that'd probably encourage more support for taxing carbon offsets since much of it goes to taxpayers as cash in their pocket.
