Every guide here follows the same discipline: cite the primary EU regulation, show the arithmetic, then link to the live tool that applies it. No estimates presented as facts, no figures cited from memory.
Commission default emissions values under EU IR 2025/2621 (corrected by IR 2026/1740), and the real escalating 10%/20%/30% markup schedule for using them instead of verified actual data.
Read the guideHow the certificate price is set each quarter in 2026 (weekly from 2027), how many certificates you owe, and the Article 26 penalty for under-surrender.
Read the guideHow the EU ETS free-allocation benchmark credit phases out from 97.5% in 2026 to 0% in 2034 — and the common mistake of applying it to the whole obligation instead of just the credit.
Read the guideISO 17029 accreditation, what a verifier actually checks, and the August 2026 verification guidance timeline.
Read the guideThe threshold is a single annual aggregate across steel, aluminium, fertilisers, and cement combined (not per CN code) — plus the hydrogen/electricity exclusion and the anti-circumvention flag on split shipments.
Read the guideHow a carbon price paid in the country of origin reduces your CBAM certificate obligation — the parallel-credit formula, the correct reference-price divisor, and a worked example.
Read the guideThe Authorised Declarant requirement (mandatory from 1 Jan 2026), the real 30 September deadline, and what a declaration needs to pass registry submission.
Read the guideUK CBAM is a separate regime, not a UK copy of EU CBAM — different mechanism, deadlines, and verification standard, side by side.
Read the guideThe Commission's proposal to add ~180 downstream products from 1 Jan 2028 (COM(2025) 419) — where it actually stands in the legislative process right now.
Read the guideWhat actually produces a defensible SEE figure: source streams, methodology justification, and the conditional elements (PFC methodology, waste gas, zero-rated fuels) — verified against EU Reg 2023/956 Art. 8.
Read the guideWhy the Cross-Sectoral Correction Factor is not optional in the benchmark-credit formula (currently 1.0, per Commission CBAM Guidance No. 4), and a real correction history from our own calculation engine.
Read the guideHow perfluorocarbon emissions from the anode effect are calculated, the CF4/C2F6 GWP constants, and why anode-effect control can roughly triple embedded emissions at identical production volume.
