Great idea. Now US companies down the supply chain have a higher cost of goods sold too. US Steel is technically more competitive domestically, but is worse off internationally. You have successfully incentivized even more businesses to leave the United States and have lost millions of jobs. You have possibly violated several trade agreements too but let's ignore that.

So what now? We haven't accomplished much other than moving manufacturing to other countries. Are we just going to tax the finished goods coming into the country too because they were made with dirty fuels too? Because people are already pretty unhappy, including auto manufacturers, pretty much anyone who actually makes stuff, and also people who need to eat food. Especially people who just lost their jobs due to your earlier choices.

Ideally yes. That's the basic problem with international trade. If you try to do something that's better for the world, someone will eat your lunch, your people will suffer, and little will change.
