As the clock struck midnight on January 1, 2026, a new chapter in the history of world trade would be turned. The EU's Carbon Border Adjustment Mechanism (CBAM) would officially come into effect. It would no longer be just a clause in a Brussels conference room, but would become a "green invoice," accompanying every shipment of steel, aluminum, cement, fertilizer, electricity, and hydrogen into the ports of the 27 EU member states.
For Chinese exporters, this invoice could potentially eat up 10%–15% of their profits, or it could become a "VIP pass" to the global low-carbon supply chain.
On January 1, 2026, the EU's Carbon Border Adjustment Mechanism (CBAM) officially entered its full implementation phase. This policy, commonly known as the "EU carbon tariff," marks the implementation of the first mandatory carbon cost transmission mechanism in the global trade arena.
As a core pillar of the EU's "Fit for 55" climate package, CBAM not only reshapes the rules of economic exchange between the EU and its global trading partners, but also has a profound impact on export-oriented economies, represented by China.
First and foremost, it's important to clarify that CBAM is not a tariff, but rather a "carbon differential."
Legal Definition: CBAM falls under EU Regulation 2023/956, a "protective measure" protected by WTO environmental exceptions. It takes effect directly in the 27 member states without requiring parliamentary approval.
Economic Substance: It only taxes the "carbon differential," i.e., "EU carbon price – carbon price already paid by the exporting country." If the Chinese carbon market eventually covers steel and raises prices, CBAM will decrease accordingly, theoretically potentially reaching zero.
Technical Substance: It requires importers to purchase and settle "CBAM certificates," one certificate per ton of CO₂, with the price anchored to the annual average price of EU ETS. The 2025 EU ETS average price is €90/ton, more than ten times the annual average price of 60 RMB in China's national carbon market, representing a huge potential price difference.
For Chinese companies deeply rooted in the EU market, this is no longer a "transitional exercise," but a "life-or-death test" concerning cost control, compliant survival, and long-term development.
