Such coordination would be great, but carbon taxes aren't doomed to fail without it. I'd guess that every country has taxes that are worse for competitiveness than a carbon tax, and can be displaced. Additionally, carbon border adjustments can partially impose a carbon tax on producers in countries that won't do it themselves.
