On January 1, the EU’s Carbon Border Adjustment Mechanism(CBAM) – a levy that prices the carbon embedded in imported goods – flipped from a reporting exercise to a financial obligation. That same day, Serbia enacteda carbon tax of €4 per ton of CO₂ on its heaviest emitters. The timing was not a coincidence, and the gap between those two prices tells the real story.
Serbia now faces a trilemma with no clean exit: keep Chinese capital flowing, meet EU climate benchmarks required for accession, and avoid carbon surcharges that could render its biggest export sector uncompetitive. Satisfying any two of these objectives undermines the third. The sharpest test case sits in Smederevo, where HBIS (formerly Hebei Iron and Steel) Group operates a steel plant that is simultaneously Serbia’s largest exporter, Beijing’s flagship industrial investment in the Western Balkans, and one of the dirtiest steel operations shipping product into Europe.
