Illustrative estimate

This example multiplies quantity × assumed emissions × assumed certificate price × the free-allocation phase-out share. It omits the benchmark-based free-allocation adjustment, precursor and production-route details, deduction of a carbon price already paid, and the applicable legal emissions rules. The inputs are illustrative assumptions, not official default values or a current price quote. This is not the amount legally payable.

The annual 50-tonne exemption is measured per importer, in aggregate across covered cement, fertilisers, iron and steel, and aluminium. At or below 50 tonnes, the exemption applies; above it, obligations cover all relevant imports that year. Electricity and hydrogen are excluded from this exemption. The shipment quantity here does not establish eligibility.

Free-allocation phase-out share: 2026 2.5%; 2027 5%; 2028 10%; 2029 22.5%; 2030 48.5%; 2031 61%; 2032 73.5%; 2033 86%; 2034 100%.
