Not just simple fraud, but a major hurdle is how to regulate CO2 necessary for producing consumer energy without creating a regressive tax structure. Once CO2 is converted to electricity on the grid, it's fungible and impossible to sort out luxury vs necessity.

Imho, government trying to sin-tax away CO2 is result of our failure to invest in technology solutions.

Not so hard. It's fine if any individual tax is regressive, as long is counterbalanced by UBI or other forms of per-capita welfare support. You don't need to measure precisely, as long as you get rough estimates that people pay $Y in various sin-taxes but get $X>$Y in general welfare benefits.

I absolutely disagree. Inserting the government into the average citizen's balance sheet can and will be corrupted.
