One way I've heard is to have an import duty on carbon at the border. You have your internal tax on carbon at the source, nationally. If another country has a similar tax, their goods can be imported without extra duties. If they don't, you assess the goods imported and charge the equivalent duty. If the carbon tax rate is different you can pro-rate.
That way, local producers aren't competing against cheap, dirty, manufacturing overseas, and other countries are encouraged to assess their own carbon tax to avoid the import duties.
It's a very fair system that allows countries to onboard one at a time, instead of all together. Unfortunately it would probably be considered illegal under the WTO.

The equivalent duty meaning same as carbon taxers or less? (asuming non carbon taxers have less duty)
When I first heard about it, I thought it was a movement which is not caring about the environment. That 1 million French are vocally opposed to the environment. It's more complex than that but taxing carbon would lead to protests of the masses.
