The European Union has officially published the Carbon Border Adjustment Mechanism (CBAM) legislation in the EU Official Journal, with effect from May 17 – the day following publication. This completes all procedures for the EU carbon tariff to formally enter into force.
What is CBAM?
CBAM is a core part of the EU’s “Fit for 55” emissions reduction package (targeting a 55% cut in emissions from 1990 levels by 2030). In simple terms, the EU imposes charges on high‑carbon imports from third countries based on their embedded emissions.
Primary Objectives
The carbon tariff aims to prevent “carbon leakage” – where EU manufacturers relocate to regions with weaker environmental standards, yielding no net global CO₂ reduction. It protects EU producers, raises costs for external producers with lax targets, and discourages relocation. Meanwhile, the EU Emissions Trading System (EU‑ETS) will phase out free allowances by 2032.
Implementation Timeline & Scope
CBAM initially covers cement, steel, aluminum, fertilizers, electricity, and hydrogen.
▪ Trial period: October 1, 2023 – December 31, 2025
▪ Full implementation: January 1, 2026
Importers must purchase CBAM certificates priced according to weekly EU ETS allowance auctions (€/t CO₂).
Impact on China
As the EU’s largest trading partner, China faces significant implications:
▪ 80% of carbon emissions from China’s EU‑bound intermediate products come from metals, chemicals, and non‑metallic minerals – high‑risk sectors under CBAM.
▪ Estimated 5‑7% of China’s total exports to Europe affected, with export reduction of 11‑13% for covered sectors.
▪ Additional annual costs: $100‑300 million (1.6‑4.8% of covered exports).
For China’s steel industry, per‑ton carbon emissions exceed EU standards by 1 ton, potentially adding ~¥650/ton in costs (11% tax burden).
Opportunities and Challenges
While increasing export pressure, CBAM also offers green opportunities:
▪ China’s carbon market remains nascent; stronger EU communication is needed.
▪ Traditional industries must pursue “quality enhancement and carbon reduction.”
▪ The photovoltaic and new energy sectors may gain export stimulus and attract European clean technology investments, turning the carbon tariff into a catalyst for China’s PV industry.
