EU CBAM First Certificate Surrender

What this countdown tracks

30 September 2026 is the first deadline for authorised CBAM declarants to surrender certificates matching embedded-emissions imports of covered goods into the EU during 2026. The Carbon Border Adjustment Mechanism moves from a transitional reporting phase into its definitive financial phase on 1 January 2026, and this date is the first actual compliance surrender.

Background

Regulation (EU) 2023/956 established CBAM as the companion tool to the EU Emissions Trading System, designed to prevent carbon leakage by pricing embedded greenhouse-gas emissions in imports of carbon-intensive goods. The transitional phase ran from 1 October 2023 to 31 December 2025: importers filed quarterly reports on embedded emissions but paid no charges. The definitive phase begins 1 January 2026, covering six product groups — cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen — with some further downstream products.

From 1 January 2026, only "authorised CBAM declarants" may import covered goods. They must purchase CBAM certificates priced weekly at the average EUA auction price, track embedded direct and (for cement and fertilisers) indirect emissions at the installation level, and surrender certificates by 30 September of the year following import. The first surrender — 30 September 2026 — covers calendar year 2026 imports. A simplified 2025 Omnibus package raised the de minimis threshold to 50 tonnes per year (the "small-importer" exemption covering an estimated 90% of declarants but only a small share of emissions) and streamlined verification rules, but left the 30 September 2026 deadline intact. CBAM's phase-in mirrors the gradual phase-out of free allocation to European producers in equivalent sectors under ETS 1: free allocation reduces from 97.5% in 2026 to zero in 2034, with CBAM liability scaling up in lockstep to avoid double protection. Major exporter countries including India, China, Brazil, and Türkiye have formally raised CBAM compatibility concerns at the WTO Committee on Trade and Environment, and the UK announced its own domestic CBAM for a 2027 launch to preserve cross-border consistency.

Why the date matters

30 September 2026 is the first moment CBAM generates actual cash outflows from importers to the EU budget via surrendered certificates. It sets the baseline for compliance cost pass-through into steel, cement, aluminium, and fertiliser prices across European supply chains. It is also the first test of the default-values system, the installation-emission verification regime, and the interaction with the gradual ETS free-allocation phase-out running 2026–2034. Early surrender data will directly feed the Commission's forthcoming review of scope expansion to downstream products, polymers, and organic chemicals — a review the 2025 Omnibus package left pencilled in for 2027.

What to watch for

• Share of imports using verified installation data versus default values.
• Total CBAM certificate revenue in the first surrender cycle.
• WTO responses and challenges from third-country governments.
• Market-share shifts between EU and non-EU producers of covered goods.
• Capacity and backlog at national CBAM competent authorities.
• Compliance outcomes for importers above and below the 50-tonne threshold.
• Signals on CBAM scope expansion to downstream and organic-chemical goods.
