Global steel manufacturers are actively exploiting the new European Union Carbon Border Adjustment Mechanism by quietly rerouting their highly polluting operations through…

Rerouting steel does not erase its carbon

The EU’s Carbon Border Adjustment Mechanism, or CBAM, is designed to put a carbon cost on certain imported goods, including iron and steel. Its purpose is to reduce the incentive to move production abroad simply to avoid the carbon costs faced by producers in Europe. The key measure is not the route a shipment takes, but the emissions associated with making the covered goods.

That distinction matters. Sending steel through Turkey or another intermediary country does not, by itself, change where or how it was produced. Nor does a new label make emissions disappear. Importers must provide information about covered goods and their production emissions; under the mechanism’s rules, those figures help determine the carbon obligation.

Where the loophole risk actually lies

Trade can involve several countries: one may melt the steel, another roll it into a different product, and a third export it. Customs rules determine a product’s origin, while CBAM accounting tracks emissions tied to its production. Those are related but not identical questions, and complex supply chains can make both harder to verify.

A company might have an incentive to obscure a product’s production history, misstate its origin, or provide unreliable emissions data. But simple transshipment—shipping a product through another country without meaningfully changing it—is not a legitimate way to reset its origin or carbon footprint. Deliberate misreporting can bring customs or regulatory consequences, though checking claims across complicated supply chains is a real enforcement challenge.

The practical test is traceability

The mechanism’s effectiveness therefore depends less on where a vessel stops than on whether authorities and importers can connect a steel product to the facilities and processes that made it. Better records and verification make it harder to pass high-emissions goods off as something else; weak documentation creates room for evasion.

The important distinction is between a genuine change in production and a change in paperwork. A shipment can take a longer route into Europe. Its carbon history travels with it.
