Official prices: European Commission, “Price of CBAM certificates” (CC BY 4.0). “Our method” applies the Commission’s published rule, the volume-weighted average of EU ETS auction clearing prices in the quarter, to EEX auction results. It matches every official 2026 quarter to the cent, which is why we publish a running estimate for the current quarter.
Weekly prices, ready for 2027
From 2027 the Commission will publish a CBAM price every week. Here is the same calculation for recent weeks, so you can see how much it moves.

| 2 November 2026 | 4 | €89.50 |

Our calculation, not an official price. From 2027 the Commission publishes its own weekly price under Implementing Regulation (EU) 2025/2548. The official price also counts aviation allowance auctions; none have been held in 2025 or 2026, and our estimate leaves them out.
CBAM price questions
What is the CBAM certificate price?
The European Commission set the CBAM certificate price for Q3 2026 at €82.32 per tonne of CO2 equivalent, published on 5 October 2026. It applies to emissions in CBAM goods imported into the EU during that quarter.
How is the CBAM certificate price calculated?
It is the volume-weighted average of the clearing prices of EU ETS allowance auctions over the period. In 2026 the Commission calculates one price per quarter in the first calendar week after the quarter ends and publishes it on the first working day of the following week. From 2027 it publishes a weekly price.
What will the Q4 2026 CBAM price be?
It will be published on 4 January 2027. Applying the Commission's method to the 28 EU auctions held so far this quarter gives €86.69 per tonne. This is our estimate and will move until the quarter ends.
When can CBAM certificates be bought?
Sales of CBAM certificates on the EU common central platform start on 1 February 2027. Authorised declarants must surrender certificates for 2026 imports by 30 September 2027.
Is there a UK CBAM certificate?
No. UK CBAM, which starts on 1 January 2027, is a tax paid to HMRC at a rate set by HM Treasury for each sector. There are no certificates to buy.
