I disagree. I think we should:

1. Pilot it to prove the cost
2. Charge a carbon tax based loosely on that number and (high) estimates for the amount of carbon emitted
3. Return the carbon tax to the public as a credit

This keeps the tax revenue neutral (i.e. theoretically no hit to GDP) while encouraging companies to find cheaper ways to reduce carbon emissions or capture carbon to offset emissions.

If it’s ineffective at reducing emissions, then start spending a portion of it to remove carbon.
