Why CBAM matters
CBAM turns the embedded carbon of a product into a direct financial cost. Two suppliers of the same steel or aluminium now compete not only on price but on carbon intensity, because the higher-carbon product carries a larger certificate bill at the EU border. For non-EU producers, supplying verified, product-specific emissions data has become a condition of staying competitive in the European market.
There's a sharper way to see it. CBAM is less a tax than a data competition. The importer who can prove low actual emissions pays less; the one who cannot is assigned high default values and pays more.
How CBAM works
EU importers of in-scope goods must determine the embedded emissions of each product, covering both direct emissions from production and, for some goods, indirect emissions from electricity. They then report those emissions and surrender certificates priced against the EU ETS allowance price. Importers can use actual emissions data from their suppliers, but to do so they must define system boundaries, track precursor emissions, distinguish production routes, and obtain third-party verification. Where actual data isn't available, default values apply, and these are deliberately set high enough to incentivise real data.
The CBAM timeline
CBAM ran a transitional phase from 1 October 2023 to 31 December 2025, during which importers reported embedded emissions but paid nothing. The definitive phase began on 1 January 2026: certificate obligations now apply, with the first annual declaration and certificate surrender due in 2027 for goods imported in 2026. A legally binding de minimis exemption excludes importers below 50 tonnes of CBAM goods per year, removing most small importers from scope. The EU has signalled an intended expansion of scope to additional downstream goods from 2028.
CBAM and life cycle assessment
CBAM's embedded-emissions calculation is, in effect, a regulated product carbon footprint with verification-grade scrutiny. The same disciplines that make an LCA defensible, namely clear system boundaries, traceable primary data, and documented data quality, are what make a CBAM emissions figure survive verification. For producers of metals and materials, the work of building an auditable product footprint and the work of preparing for CBAM are largely the same exercise.
