The World Trade Organization has agreed to consider Russia's complaint that the European Union's carbon border adjustment mechanism (CBAM) creates unfair trade barriers. The EU has argued that Russia's challenge should be dismissed because Russia is waging a war of aggression, but the WTO panel will now examine the case on its merits. This is a significant development for the future of carbon pricing on imports, as it tests whether climate measures can survive trade law scrutiny. The outcome could set a precedent for how countries design carbon border levies without violating WTO rules. For carbon markets and low-carbon industry, the case adds another layer of legal risk and uncertainty. If the WTO finds CBAM breaches trade commitments, the EU may need to revise the mechanism. If it upholds the levy, other jurisdictions may feel more confident introducing similar carbon border measures. Either way, the decision will shape how trade and climate policy interact for years to come.
