Regulation (EU) 2023/956 of the European Parliament and of the Council of 10 May 2023 establishing a carbon border adjustment mechanism (Text with EEA relevance)

This Regulation establishes a carbon border adjustment mechanism (the ‘CBAM’) to address greenhouse gas emissions embedded in the goods listed in Annex I on their importation into the customs territory of the Union in order to prevent the risk of carbon leakage, thereby reducing global carbon emissions and supporting the goals of the Paris Agreement, also by creating incentives for the reduction of emissions by operators in third countries.

The CBAM complements the system for greenhouse gas emission allowance trading within the Union established under Directive 2003/87/EC (the ‘EU ETS’) by applying an equivalent set of rules to imports into the customs territory of the Union of the goods referred to in Article 2 of this Regulation.

The CBAM is set to replace the mechanisms established under Directive 2003/87/EC to prevent the risk of carbon leakage by reflecting the extent to which EU ETS allowances are allocated free of charge in accordance with Article 10a of that Directive.

This Regulation applies to goods listed in Annex I originating in a third country, where those goods, or processed products from those goods resulting from the inward processing procedure referred to in Article 256 of Regulation (EU) No 952/2013, are imported into the customs territory of the Union.

This Regulation also applies to goods listed in Annex I to this Regulation originating in a third country, where those goods, or processed products from those goods resulting from the inward processing procedure referred to in Article 256 of Regulation (EU) No 952/2013, are brought to an artificial island, a fixed or floating structure, or any other structure on the continental shelf or in the exclusive economic zone of a Member State that is adjacent to the customs territory of the Union.

By way of derogation from paragraphs 1 and 2, this Regulation shall not apply to goods to be moved or used in the context of military activities pursuant to Article 1, point (49), of Commission Delegated Regulation (EU) 2015/2446 ([^E0001]).

By way of derogation from paragraphs 1 and 2, this Regulation shall not apply to goods originating in the third countries and territories listed in point 1 of Annex III.

Imported goods shall be considered as originating in third countries in accordance with the rules for non-preferential origin as referred to in Article 59 of Regulation (EU) No 952/2013.

Third countries and territories shall be listed in point 1 of Annex III where they fulfil all the following conditions:

If a third country or territory has an electricity market which is integrated with the Union internal market for electricity through market coupling, and there is no technical solution for the application of the CBAM to the importation of electricity into the customs territory of the Union from that third country or territory, such importation of electricity from that country or territory shall be exempt from the application of the CBAM, provided that the Commission has assessed that all of the following conditions have been fulfilled in accordance with paragraph 8:

A third country or territory that fulfils all the conditions set out in paragraph 7, shall be listed in point 2 of Annex III, and shall submit two reports on the fulfilment of those conditions, the first report by 1 July 2025 and the second by 31 December 2027. By 31 December 2025 and by 1 July 2028, the Commission shall assess, in particular on the basis of the roadmap referred to in paragraph 7, point (c), and the reports received from the third country or territory, if that third country or territory continues to fulfil the conditions set out in paragraph 7.

A third country or territory listed in point 2 of Annex III shall be removed from that list where one or more of the following conditions applies:

The Commission is empowered to adopt delegated acts in accordance with Article 28 in order to supplement this Regulation by laying down requirements and procedures for third countries or territories that have been removed from the list in point 2 of Annex III, to ensure the application of this Regulation to those countries or territories with regard to electricity. If in such cases market coupling remains incompatible with the application of this Regulation, the Commission may decide to exclude those third countries or territories from Union market coupling and require explicit capacity allocation at the border between the Union and those third countries or territories, so that the CBAM can apply.

The Commission is empowered to adopt delegated acts in accordance with Article 28 in order to amend the lists of third countries or territories listed in point 1 or 2 of Annex III by adding or removing a third country or territory, depending on whether the conditions set out in paragraph 6, 7 or 9 of this Article are fulfilled in respect of that third country or territory.

The Union may conclude agreements with third countries or territories with a view to taking into account carbon pricing mechanisms in such countries or territories for the purposes of the application of Article 9.

An importer, including any importer with the status of an authorised CBAM declarant, shall be exempted from the obligations under this Regulation, where the net mass of the imported goods in a given calendar year does not cumulatively exceed the single mass-based threshold laid down in point 1 of Annex VII (the “single mass-based threshold”). That threshold shall apply to the total net mass of goods under all CN codes aggregated per importer and per calendar year. In such a case, the importer, including an importer with the status of an authorised CBAM declarant, shall declare that exemption in the relevant customs declaration.

Where, within the relevant calendar year, an importer, including any importer with the status of an authorised CBAM declarant, exceeds the single mass-based threshold, the importer or the authorised CBAM declarant shall be subject to all obligations under this Regulation in respect of all emissions embedded in all goods imported in that calendar year.

By 30 April of each calendar year, the Commission shall assess, on the basis of the import data for the preceding 12 calendar months, whether the single mass-based threshold ensures that paragraph 1 of this Article applies to no more than 1 % of the emissions embedded in the imported goods and processed products. The Commission shall adopt delegated acts in accordance with Article 28 to amend the single mass-based threshold by using the methodology set out in point 2 of Annex VII, where the value of the resulting threshold deviates from the applicable threshold by more than 15 tonnes. The amended single mass-based threshold shall apply from 1 January of the following calendar year.

This Article shall not apply to imports of electricity or hydrogen.

Any importer established in a Member State shall, prior to importing goods into the customs territory of the Union, apply for the status of authorised CBAM declarant (“application for an authorisation”).

Where an importer is not established in a Member State, the indirect customs representative shall obtain the status of authorised CBAM declarant, irrespective of whether the importer is exempted from the obligations under this Regulation pursuant to Article 2a.

The application for an authorisation shall be submitted via the CBAM registry established in accordance with Article 14.

By way of derogation from paragraph 1, where transmission capacity for the import of electricity is allocated through explicit capacity allocation, the person to whom capacity has been allocated for import and who nominates that capacity for import shall, for the purposes of this Regulation, be regarded as an authorised CBAM declarant in the Member State where the person has declared the importation of electricity in the customs declaration. Imports are to be measured per border for time periods no longer than one hour and no deduction of export or transit in the same hour shall be possible.

The application for an authorisation shall include the following information about the applicant:

The applicant may withdraw its application at any time.

The authorised CBAM declarant shall inform without delay the competent authority, via the CBAM registry, of any changes to the information provided under paragraph 5 of this Article that have occurred after the decision granting the status of the authorised CBAM declarant has been adopted pursuant to Article 17 that may influence that decision or the content of the authorisation granted thereunder.

The Commission is empowered to adopt implementing acts on communications between the applicant, the competent authority and the Commission, on the standard format of the application for an authorisation and the procedures to submit such an application via the CBAM registry, on the procedure to be followed by the competent authority and the deadlines for processing applications for authorisation in accordance with paragraph 1 of this Article, and on the rules for identification by the competent authority of the authorised CBAM declarants for the importation of electricity. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 29(2).

By 30 September of each year, and for the first time in 2027 for the year 2026, each authorised CBAM declarant shall use the CBAM registry referred to in Article 14 to submit a CBAM declaration for the preceding calendar year.

The CBAM declaration shall contain the following information:

Where processed products resulting from an inward processing procedure as referred to in Article 256 of Regulation (EU) No 952/2013 are imported, the authorised CBAM declarant shall report in the CBAM declaration the emissions embedded in the goods that were placed under the inward processing procedure and resulted in the imported processed products, even where the processed products are not goods listed in Annex I to this Regulation. This paragraph shall also apply where the processed products resulting from the inward processing procedure are returned goods as referred to in Article 205 of Regulation (EU) No 952/2013.

Where the imported goods listed in Annex I to this Regulation are processed products resulting from an outward processing procedure as referred to in Article 259 of Regulation (EU) No 952/2013, the authorised CBAM declarant shall report in the CBAM declaration only the emissions of the processing operation undertaken outside the customs territory of the Union.

Where the imported goods are returned goods as referred to in Article 203 of Regulation (EU) No 952/2013, the authorised CBAM declarant shall report separately, in the CBAM declaration, ‘zero’ for the total embedded emissions corresponding to those goods.

The Commission is empowered to adopt implementing acts concerning the standard format of the CBAM declaration, including detailed information for each installation and country of origin or other third country and type of goods to be reported, which supports the totals referred to in paragraph 2 of this Article, in particular as regards embedded emissions, the carbon price paid, the default carbon price for the purpose of Article 9(4), the procedure for submitting the CBAM declaration via the CBAM registry, and the arrangements for surrendering the CBAM certificates referred to in paragraph 2, point (c), of this Article, in accordance with Article 22(1), in particular as regards the process and the selection by the authorised CBAM declarant of certificates to be surrendered. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 29(2).

Embedded emissions in goods shall be calculated pursuant to the methods set out in Annex IV. For goods listed in Annex II only direct emissions shall be calculated and taken into account.

Embedded emissions in goods other than electricity shall be determined:

Embedded emissions in imported electricity shall be determined by reference to default values in accordance with the method set out in point 4.2 of Annex IV, unless the authorised CBAM declarant demonstrates that the criteria to determine the embedded emissions based on the actual emissions listed in point 5 of Annex IV are met.

Embedded indirect emissions shall be calculated in accordance with the method set out in point 4.3 of Annex IV and further specified in the implementing acts adopted pursuant to paragraph 7 of this Article, unless the authorised CBAM declarant demonstrates that the criteria to determine the embedded emissions based on actual emissions that are listed in point 6 of Annex IV are met.

The authorised CBAM declarant shall keep records of the information required to calculate the embedded emissions in accordance with the requirements laid down in Annex V. Those records shall be sufficiently detailed to enable verifiers accredited pursuant to Article 18, where applicable, to verify the embedded emissions in accordance with Article 8 and Annex VI and to enable the Commission and the competent authority to review the CBAM declaration in accordance with Article 19(2).

The authorised CBAM declarant shall keep those records of information referred to in paragraph 5, including the report of the verifier, until the end of the fourth year after the year in which the CBAM declaration has been or should have been submitted.

The Commission is empowered to adopt implementing acts concerning:

Where the embedded emissions are determined on the basis of actual emissions, the authorised CBAM declarant shall ensure that the total embedded emissions declared in the CBAM declaration submitted pursuant to Article 6 are verified by a verifier accredited pursuant to Article 18, based on the verification principles set out in Annex VI.

For embedded emissions in goods produced in installations in a third country registered in accordance with Article 10, the authorised CBAM declarant may choose to use verified information disclosed to it in accordance with Article 10(7) to fulfil the obligation referred to in paragraph 1 of this Article.

The Commission is empowered to adopt implementing acts for the application of the verification principles set out in Annex VI as regards:

Where the embedded emissions are determined on the basis of actual emissions, an authorised CBAM declarant may claim in the CBAM declaration a reduction in the number of CBAM certificates to be surrendered in order to take into account the carbon price paid in a third country for the declared embedded emissions. The reduction may be claimed only if the carbon price has been effectively paid in a third country. In such a case, any rebate or other form of compensation available in that country that would have resulted in a reduction of that carbon price shall be taken into account.

The authorised CBAM declarant shall keep records of the documentation required to demonstrate that the declared embedded emissions were subject to a carbon price in a third country that has been effectively paid as referred to in paragraph 1. The authorised CBAM declarant shall in particular keep evidence related to any rebate or other form of compensation available, in particular the references to the relevant legislation of that country. The information contained in that documentation shall be certified by a person that is independent from the authorised CBAM declarant and from the authorities of the third country. The name and contact information of that independent person shall appear on the documentation. The authorised CBAM declarant shall also keep evidence of the actual payment of the carbon price.

The authorised CBAM declarant shall keep the records referred to in paragraph 2 until the end of the fourth year after the year during which the CBAM declaration has been or should have been submitted.

By way of derogation from paragraphs 1, 2 and 3, an authorised CBAM declarant may claim, in the CBAM declaration, a reduction in the number of CBAM certificates to be surrendered in order to take into account the carbon price paid for the declared embedded emissions, by reference to yearly default carbon prices. In such a case, any rebate or other form of compensation available in that country that would have resulted in a reduction of that default carbon price shall be taken into account. The reduction may be claimed only where a carbon price was set by the rules applicable in the third country and a yearly default carbon price can be determined, including on a conservative basis, for that third country. Where the embedded emissions are determined on the basis of default values, a reduction may be claimed only by a reference to yearly default carbon prices.

The Commission is empowered to adopt implementing acts concerning the conversion of the yearly average carbon price effectively paid in accordance with paragraph 1 of this Article and of the yearly default carbon prices determined in accordance with paragraph 4 of this Article into a corresponding reduction of the number of CBAM certificates to be surrendered. Those acts shall also govern the conversion of the carbon price expressed in foreign currency into euro at the yearly average exchange rate, the evidence required of the actual payment of the carbon price, examples of any relevant rebate or other form of compensation referred to in paragraph 1 of this Article, the qualifications of the independent person referred to in paragraph 2 of this Article and the conditions to ascertain that person’s independence. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 29(2).

The Commission shall, upon request by an operator of an installation located in a third country, register the information on that operator and on its installation in the CBAM registry referred to in Article 14.

The request for registration referred to in paragraph 1 shall contain the following information to be included in the CBAM registry upon registration:

The Commission shall notify the operator of the registration in the CBAM registry. The registration shall be valid for a period of five years from the date of its notification to the operator of the installation.

The operator shall inform the Commission without delay of any changes in the information referred to in paragraph 2 arising after the registration, and the Commission shall update the relevant information in the CBAM registry.

The operator shall:

The records referred to in paragraph 5, point (c), of this Article shall be sufficiently detailed to enable the verification of the embedded emissions in accordance with Article 8 and Annex VI, and to enable the review, in accordance with Article 19, of the CBAM declaration made by an authorised CBAM declarant to whom the relevant information was disclosed in accordance with paragraph 7 of this Article.

An operator may disclose the information on the verification of embedded emissions and the carbon price paid in a third country referred to in paragraph 5 of this Article to an authorised CBAM declarant. The authorised CBAM declarant shall be entitled to use that disclosed information in order to fulfil the obligation referred to in Article 8.

The operator may, at any time, ask to be deregistered from the CBAM registry. The Commission shall, upon such request, and after notifying the competent authorities, deregister the operator and delete the information on that operator and on its installation from the CBAM registry, provided that such information is not necessary for the review of CBAM declarations that have been submitted. The Commission may, after having given the operator concerned the possibility to be heard and having consulted with the relevant competent authorities, also deregister the information if the Commission finds that the information on that operator is no longer accurate. The Commission shall inform the competent authorities of such deregistration.

Where an accreditation is granted in accordance with Article 18, the verifier shall submit a request for registration in the CBAM registry to the competent authority of the Member State in which the national accreditation body is established. The verifier shall submit the request for registration within two months of the date on which the accreditation was granted, but not before 1 September 2026. The competent authority shall register the information on the accredited verifier in the CBAM registry.

The request for registration in the CBAM registry referred in paragraph 1 shall at least contain the following information:

The competent authority shall notify the verifier of the registration in the CBAM registry. The competent authority shall also notify, through the CBAM registry, the Commission and the other competent authorities of the registration.

The verifier shall notify the competent authority of any changes to the information referred to in paragraph 2 arising after the registration in the CBAM registry. The competent authority shall ensure that the CBAM registry is updated accordingly.

For the purpose of Article 10(5), point (b), the verifier shall use the CBAM registry to verify the embedded emissions.

The competent authority shall deregister a verifier from the CBAM registry where that verifier is no longer accredited pursuant Article 18 or where the verifier has not complied with the obligation laid down in paragraph 4 of this Article. The competent authority shall notify the Commission and the other competent authorities of the deregistration. The competent authority shall delete the information on that accredited verifier from the CBAM registry provided that such information is not necessary for the review of CBAM declarations that have been submitted.

Each Member State shall designate the competent authority to carry out the functions and duties under this Regulation, inform the Commission thereof and ensure that the competent authority has all the powers necessary to perform those functions and duties.

Competent authorities shall exchange any information that is essential or relevant to the exercise of their functions and duties under this Regulation.

For the purpose of the report referred to in Article 30(6), the competent authorities shall provide, at the request of the Commission and on the basis of the questionnaire, relevant information on the implementation of this Regulation.

All information acquired by the competent authority or the Commission in the course of performing their duties which is by its nature confidential or which is provided on a confidential basis shall be covered by the obligation of professional secrecy. Such information shall not be disclosed by the competent authority or the Commission without the express prior permission of the person or authority that provided it or by virtue of Union or national law.

By way of derogation from paragraph 1, the competent authorities and the Commission may share such information with each other, the customs authorities, the authorities in charge of administrative or criminal penalties, and the European Public Prosecutor’s Office, for the purposes of ensuring compliance of persons with their obligations under this Regulation and the application of customs legislation. Such shared information shall be covered by professional secrecy and shall not be disclosed to any other person or authority except by virtue of Union or national law.

The Commission shall establish a CBAM registry of authorised CBAM declarants in the form of a standardised electronic database containing the data regarding the CBAM certificates of those authorised CBAM declarants. The Commission shall make the information in the CBAM registry available automatically and in real time to customs authorities and competent authorities.

The CBAM registry referred to in paragraph 1 shall contain accounts with information about each authorised CBAM declarant, in particular:

The CBAM registry shall contain, in a separate section of the registry, the information about the operators and installations in third countries registered in accordance with Article 10(2) and the information about the accredited verifiers registered in accordance with Article 10a.

The information in the CBAM registry referred to in paragraphs 2 and 3 shall be confidential, with the exception of the names, addresses, corporate or activity registration numbers, contact information of the operators, the location of installations in third countries and the information on accredited verifiers referred to in Article 10a(2). An operator may choose not to have its name, address, corporate or activity registration number, contact information and the location of its installations made accessible to the public. The public information in the CBAM registry shall be made accessible by the Commission in an interoperable format.

The Commission shall publish, on a yearly basis, for each of the goods listed in Annex I, the aggregated emissions embedded in the imported goods.

The Commission shall adopt implementing acts concerning the infrastructure and specific processes and procedures of the CBAM registry, including the risk analysis referred to in Article 15, the electronic databases containing the information referred to in paragraphs 2 and 3 of this Article, the procedures and the technical credentials for the delegation referred to in Article 5(7a), the data of the accounts in the CBAM registry referred to in Article 16, the transmission to the CBAM registry of the information on the sale and repurchase of CBAM certificates referred to in Article 20, the cross-check of information referred to in Article 25(3) and the information referred to in Article 25a(3). Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 29(2).

The Commission shall carry out risk-based controls on the data and the transactions recorded in the CBAM registry, referred to in Article 14, to ensure that there are no irregularities in the purchase, holding, surrender, repurchase and cancellation of CBAM certificates.

If the Commission identifies irregularities as a result of the controls carried out under paragraph 1, it shall inform the competent authorities concerned so that further investigations are carried out in order to correct the identified irregularities.

The Commission shall assign to each authorised CBAM declarant a unique CBAM account number.

Each authorised CBAM declarant shall be granted access to its account in the CBAM registry.

The Commission shall set up the account as soon as the authorisation referred to in Article 17(1) is granted and shall notify the authorised CBAM declarant thereof.

If the authorised CBAM declarant has ceased its economic activity or its authorisation has been revoked, the Commission shall close the account of that authorised CBAM declarant, provided that the authorised CBAM declarant has complied with all its obligations under this Regulation.

Where an application for an authorisation is submitted in accordance with Article 5, the competent authority in the Member State in which the applicant is established shall grant the status of authorised CBAM declarant provided that the criteria set out in paragraph 2 of this Article are complied with. The status of authorised CBAM declarant shall be recognised in all Member States.

The criteria for granting the status of authorised CBAM declarant shall be the following:

Where the competent authority finds that the criteria set out in paragraph 2 of this Article are not fulfilled, or where the applicant has failed to provide information listed in Article 5(5), the granting of the status of authorised CBAM declarant shall be refused. Such decision to refuse the status of authorised CBAM declarant shall provide the reasons for the refusal and include information on the possibility to appeal.

A decision of the competent authority granting the status of authorised CBAM declarant shall be registered in the CBAM registry and shall contain the following information:

For the purpose of complying with the criteria set out in paragraph 2, point (b), of this Article, the competent authority shall require the provision of a guarantee if the applicant was not established throughout the two financial years preceding the year when the application in accordance with Article 5(1) was submitted.

Where the competent authority establishes that the guarantee provided does not ensure, or is no longer sufficient to ensure, the financial and operational capacity of the authorised CBAM declarant to fulfil its obligations under this Regulation, it shall require the authorised CBAM declarant to choose between providing an additional guarantee or replacing the initial guarantee with a new guarantee in accordance with paragraph 5.

The competent authority shall release the guarantee immediately after 30 September of the second year in which the authorised CBAM declarant has surrendered CBAM certificates in accordance with Article 22.

The competent authority shall revoke the status of authorised CBAM declarant where:

The competent authority shall register in the CBAM registry information on:

The Commission shall adopt, by means of implementing acts, the conditions for:

A national accreditation body may, on request, accredit a legal person to be a verifier for the purpose of this Regulation where it considers, on the basis of the documentation submitted to it, that such person has the capacity to apply the verification principles referred to in Annex VI when performing the tasks of verification of the embedded emissions pursuant to Articles 8 and 10. Where the legal person is accredited in accordance with Implementing Regulation (EU) 2018/2067 for a relevant group of activities, the national accreditation body shall take such accreditation into account for the assessment of the qualifications of an accredited verifier that are necessary to perform the verification for the purpose of this Regulation.

The Commission is empowered to adopt delegated acts in accordance with Article 28 in order to supplement this Regulation by specifying the conditions for granting of accreditation referred to in paragraph 2 of this Article, for the control and oversight of accredited verifiers, for the withdrawal of accreditation and for mutual recognition and peer evaluation of accreditation bodies.

The Commission shall have the oversight role in the review of CBAM declarations.

The Commission may review CBAM declarations, in accordance with a review strategy, including risk factors, within the period ending with the fourth year after the year during which the CBAM declarations should have been submitted.

The Commission shall periodically set out specific risk factors and points for attention, based on a risk analysis in relation to the implementation of the CBAM at Union level, taking into account information contained in the CBAM registry, data communicated by customs authorities, and other relevant information sources, including the controls and checks carried out pursuant to Article 15(2) and Article 25.

Where an authorised CBAM declarant fails to submit a CBAM declaration in accordance with Article 6, or where the Commission considers, on the basis of its review under paragraph 2 of this Article, that the declared number of CBAM certificates is incorrect, the Commission shall assess the obligations under this Regulation of that authorised CBAM declarant on the basis of the information at its disposal. The Commission shall establish a preliminary calculation of the total number of CBAM certificates which should have been surrendered, at the latest by the 31 December of the year following that in which the CBAM declaration should have been submitted, or at the latest by 31 December of the fourth year following that in which the incorrect CBAM declaration has been submitted, as applicable. The Commission shall provide to competent authorities such a preliminary calculation, for indicative purposes and without prejudice to the definitive calculation established by the competent authority of the Member State where the authorised CBAM declarant is established.

Where the competent authority concludes that the declared number of CBAM certificates to be surrendered is incorrect, or that no CBAM declaration has been submitted in accordance with Article 6, it shall determine the number of CBAM certificates which should have been surrendered by the authorised CBAM declarant, taking into account the information submitted by the Commission.

Where the competent authority concludes that the number of CBAM certificates surrendered exceeds the number which should have been surrendered, it shall inform the Commission without delay. The CBAM certificates surrendered in excess shall be repurchased in accordance with Article 23.

From 1 February 2027, a Member State shall sell CBAM certificates on a common central platform to authorised CBAM declarants established in that Member State.

The Commission shall establish and manage the common central platform following a joint procurement procedure between the Commission and the Member States.

The information on the sale and repurchase of CBAM certificates in the common central platform shall be transferred to the CBAM registry at the end of each working day.

CBAM certificates shall be sold to authorised CBAM declarants at the price calculated in accordance with Article 21.

The Commission shall ensure that each CBAM certificate is assigned a unique identification number upon its creation. The Commission shall register the unique identification number and the price and date of sale of the CBAM certificate in the CBAM registry in the account of the authorised CBAM declarant purchasing that certificate.

The Commission is empowered to adopt delegated acts in accordance with Article 28 supplementing this Regulation by further specifying the timing, administration, structure and level of fees and other aspects related to the management of the sale and repurchase of CBAM certificates, as well as the organisation and use of the common central platform, seeking coherence with the procedures laid down in Commission Delegated Regulation (EU) 2023/2830 ([^E0005]). The delegated acts shall ensure that the organisation and use of the common central platform is cost-efficient, that the level of fees is set so as to strictly cover the relevant costs and that undue administrative costs are avoided.

The Commission shall calculate the price of CBAM certificates as the average of the closing prices of EU ETS allowances on the auction platform, in accordance with the procedures laid down in Delegated Regulation (EU) 2023/2830, for each calendar week.

The Commission shall publish the average price, as referred to in the second subparagraph of paragraph 1, on its website or in any other appropriate manner on the first working day of the following calendar week. That price shall apply from the first working day following that of its publication to the first working day of the following calendar week.

The Commission is empowered to adopt implementing acts on the application of the methodology provided for in paragraphs 1 and 1a of this Article to calculate the price of CBAM certificates and the practical arrangements for the publication of that price. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 29(2).

By 30 September of each year, and for the first time in 2027 for the year 2026, the authorised CBAM declarant shall surrender via the CBAM registry a number of CBAM certificates that corresponds to the embedded emissions declared in accordance with Article 6(2), point (c), and verified in accordance with Article 8, for the calendar year preceding the surrender. The Commission shall remove surrendered CBAM certificates from the CBAM registry. The authorised CBAM declarant shall ensure that the required number of CBAM certificates is available on its account in the CBAM registry.

From 2027, the authorised CBAM declarant shall ensure that the number of CBAM certificates on its account in the CBAM registry at the end of each quarter corresponds to at least 50 % of the embedded emissions in all goods it has imported since the beginning of the calendar year determined by reference to either of the following:

Where the Commission finds that the number of CBAM certificates in the account of an authorised CBAM declarant does not comply with the obligations pursuant to paragraph 2, it shall inform, via the CBAM registry, the competent authority of the Member State where the authorised CBAM declarant is established.
