Prices the embedded carbon of covered imports at the EU ETS price, mirroring the phase-out of free allowances. The definitive regime runs from 1 January 2026 with authorised-declarant status, embedded-emissions verification and certificate surrender; the 2025 simplification introduced a single 50-tonne de-minimis threshold exempting ~90% of importers.
