EU Carbon Border Tax Enters Full Implementation Phase

CBAM Goes Live

The European Union's Carbon Border Adjustment Mechanism (CBAM) has entered its full implementation phase, meaning importers must now purchase carbon certificates for goods entering the EU from countries that do not have an equivalent carbon pricing system.

What Is Covered?

The mechanism initially covers carbon-intensive sectors: cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. Importers must report the embedded emissions of their goods and buy certificates at a price matching the EU's internal carbon price.

Why It Matters

CBAM is designed to prevent carbon leakage — the risk of companies relocating production to countries with weaker climate rules. By putting a carbon price on imports, the EU ensures that foreign producers face the same carbon costs as those operating within the bloc.

Global Ripple Effects

The policy is already prompting other countries to introduce or strengthen their own carbon pricing. The UK is developing its own CBAM, and conversations are underway in the US and Australia. The EU's move is accelerating the emergence of a global carbon pricing architecture.
