Why doesn't the US utilize the fact it has some of the richest, most sought-after customers in the world. If a company wants to do business in the US, just stipulate that they have to be paying a corporate rate of X% somewhere. If that X is 21% and they are only paying 12.5% then in order to do business in America they would need to pay the US the difference. Just like California can dictate emissions standards in vehicles across the rest of the states, the US has power to dictate standards across the world. No need to get everyone on board. Note: I'm not commenting on whether corporate tax is good/bad. I'm just asking if the US wants something done why not.. do it.. and restrict those that don't from doing business here? We do that already for corruption (see the FIFA case[0]) Same could apply to carbon tax. If they don't pay a carbon tax for their GLOBAL business dealings, pay it to the US or your not welcome.
