This is the way I would want to see it happen. If pollution tax is high enough, it will incentivize companies to act more reasonably. Hopefully coal power plants will shut down permanently while blast furnaces will be modified to meet the new requirements. Processing all of that CO2 won’t be cheap, but steel production has to continue so the company doesn’t really have that many options. The government could also support the transition so that production won’t disappear into other countries.
