CBAM (Carbon Border Adjustment Mechanism) is an EU regulation requiring importers to report and eventually pay for the carbon emissions of imported goods. Since October 2023: reporting-only phase. From 2026: financial obligations begin (must purchase CBAM certificates). Affected products: cement, iron/steel, aluminium, fertilisers, electricity, hydrogen. Currently does NOT apply to most consumer goods, but may expand. Cost: CBAM certificate price = EU ETS carbon price (~€50-80/tonne).

Common Mistakes

Thinking CBAM only affects large manufacturers

💥 Consequence: Importers of CBAM goods must purchase CBAM certificates; small importers face same obligations as large ones

Fix: Check if your product falls under CBAM categories; register as authorized CBAM declarant

Ignoring CBAM transitional period reporting requirements

💥 Consequence: Quarterly reports are mandatory even during transitional period; penalties for non-reporting

Fix: Submit quarterly CBAM reports starting from reporting period; track embedded emissions data

Seller Paths

  3. 3. Submit quarterly CBAM reports during transitional period
  4. 4. Purchase CBAM certificates from EU registry (from 2026)
  5. 5. Surrender certificates annually to cover embedded emissions
