It currently costs $600 to permanently remove one ton of CO2 from the atmosphere. How many percent of the United States' CO2 emissions are subjected to this level of CO2 tax, along with similar import taxes to avoid shifting emissions to locales with no tax?

This will work.

Using $600 per ton of co2 across a 2000mi commercial flight with 150 passengers emitting 50lbs of co2 per mile, that works out to a tax of $200 per passenger (each way). Would double the price of a typical ticket

Yep.

It's pretty obvious that we need to work very hard at getting this cost down.

can you imagine the amount of fraud that will be happening in CO2 accounting? The carbon credit market is already fraud-galore!
