Climate protectionism

From the WSJ (World’s First Carbon Import Tax Approved by EU Lawmakers): 

The European Union’s parliament approved legislation to tax imports based on the greenhouse gases emitted to make them, clearing the final hurdle before the plan becomes law and enshrines climate regulation in the rules of global trade for the first time.

Tuesday’s vote caps nearly two years of negotiations on the import tax, which aims to push economies around the world to put a price on carbon-dioxide emissions while shielding the EU’s manufacturers from countries that aren’t regulating emissions as strictly, or at all. The tax gives credit to countries that put a price on carbon, allowing importers of goods from those countries to deduct payments made for overseas emissions from the amount owed at the EU’s borders. …

Governments and lawmakers in other countries are already under pressure to follow suit. The U.K. is debating whether to introduce a carbon border tax, while Democrats in Congress proposed legislation to create one. Bipartisan support for the idea is growing in the U.S., said Kevin Dempsey, president of the American Iron and Steel Institute, which represents companies such as Nucor Corp. and ArcelorMittal SA.

Of all the types of protectionism that are trending (e.g., here, here), this one might not be so bad.
