For whom though? I think if your product is going to be very expensive because of that you,ll try to find ways (less carbon emissive) to make it cheaper, and for others, who have low emissions already, they get an advantage. Also rich people generally emit much more carbon than poor people.

I'm a little bit tired of the argument, that everything gets expensive, like the money just goes to nirvana, it's a tax and a tax should steer industries (mostly) to do the right thing (in this case emit less CO2). The money can go directly to people e.g. in the form of a universal basic income.
