You don't have to do that explicitly. Tax all products by carbon emissions. Tariff all nations that do not participate in such a program. You don't have to tax beef explicitly when you tax carbon because beef is carbon intensive and so the tax is implicit. The problem is that carbon pricing is a political 3rd rail and also has no moat, so it's trivially easy for the a conservative government to pander and throw it out.
