U.S. investigates EU carbon border tax over potential trade barriers |
The United States has launched an investigation into whether the European Union's Carbon Border Adjustment Mechanism (CBAM) creates unfair trade barriers for American businesses, raising the prospect of renewed transatlantic trade tensions. Introduced in January 2026, CBAM applies to imports of aluminum, cement, fertilizers, hydrogen, iron, and steel. The mechanism aims to prevent companies from relocating carbon-intensive production to countries with weaker environmental regulations. Washington is examining the tax's impact on U.S. exporters, including compliance costs, market access, and proposed expansions to products such as washing machines and automotive parts. U.S. businesses have until November 9 to submit comments. The investigation comes amid internal EU disagreements over expanding CBAM, calculating emissions, and granting exemptions. European lawmakers are seeking stricter enforcement, while some governments favor greater flexibility. Separately, the World Trade Organization has agreed to examine Russia's challenge to CBAM, which Moscow argues creates discriminatory trade barriers.
