Carbon border taxes are unjust
The European Union's economic recovery plan is notable for its focus on climate action, sustainable investments, and a just transition fund. As part of this deal, the EU is also proposing a carbon border adjustment , also known as a carbon border tax, on imports by 2023. In the simplest terms, a carbon border adjustment is a tax on imported goods such as steel or cement, where the amount of tax d
