Through the tax, the EU hopes to set a price on the carbon emitted to make energy-intensive products like iron, steel, cement, fertilizer and aluminum in other countries. The aim is to both reduce emissions from imports and create a level-playing field for goods made in the European bloc that must meet stricter green standards.

The issue strikes at a core dilemma that policymakers are grappling with — and haggling over — at the COP28 climate conference in Dubai: How to get the world to go greener without upending more-fragile developing economies.

Developing countries are worried that the tax under the EU's planned Carbon Border Adjustment Mechanism would harm their economies and make it too expensive to trade with the bloc.

“CBAM’s sole aim is to prevent carbon leakage” elsewhere in the supply chain, European Commissioner for Climate Action Wopke Hoekstra told reporters at the COP28 conference. He said the tax is crucial for funding and achieving the EU's climate goal of slashing emissions 55% by 2030.

A recent study by the U.N. Conference on Trade and Development found that a tax of $44 per ton of carbon emitted would slash pollution from the supply chain by half. It also
