EU's Carbon Border Adjustment Mechanism

EU's Carbon Border Adjustment Mechanism: What It Means for Global Trade

The European Union's Carbon Border Adjustment Mechanism (CBAM) officially entered its definitive phase on 1 January 2026, marking a turning point in global trade and climate policy.

CBAM is a carbon tariff on carbon-intensive products — including steel, cement, aluminium, fertilisers, hydrogen and electricity — imported into the European Union. Its core purpose is to prevent "carbon leakage," where companies relocate production to countries with weaker climate regulations to avoid carbon costs.

The transitional phase ran from October 2023 to December 2025, during which importers submitted quarterly emissions reports without purchasing certificates. From 2026 onward, importers must buy CBAM certificates priced in line with the EU Emissions Trading System (ETS).

In a major update, a new 50-tonne exemption threshold was introduced, expected to exempt approximately 182,000 importers — mostly SMEs — while still covering over 99% of emissions in scope.

For businesses in the waste-to-energy and biomass sector, CBAM signals a broader shift: carbon accountability is now embedded into supply chains. Companies that can demonstrate low-carbon production processes will gain a clear competitive edge in the European market.

The era of free carbon is over — and sustainable production is now a trade advantage.
