Currently, the interim solution supports submissions of initial reports, updated initial reports, and annual information pursuant to decision 2/CMA.3, annex, chapter IV (Reporting), paragraphs 18-19.

• Please create your UNFCCC user account at https://userregistration.unfccc.int and follow the instructions provided on that website. Once your account is created, an email with instructions to finalize your registration will be automatically sent to you.
• Parties need specific access rights to upload submissions. National Focal Points can obtain these access rights by submitting a request to submission-info@unfccc.int
• If you already have an account but forgot your password, you can reset it at https://passwordreset.unfccc.int
• For any issues related to the submission portal, you can contact the UNFCCC secretariat at submission-info@unfccc.int
• Additional information about the submission portal are available on the UNFCCC Submissions and statements webpage.

The annual information, decision 2/CMA.3, annex, chapter IV.B, paragraph 20, is encouraged to be submitted in accordance with the draft version of the agreed electronic format pursuant to decision 6/CMA.4, paragraph 2, which is included in annex VII of the same decision.

As per decision 2/CMA.3, annex, paragraph 20, the annual submission must include "Annual information on authorization of ITMOs for use towards achievement of NDCs, authorization of ITMOs for use towards other international mitigation purposes, first transfer, transfer, acquisition, holdings, cancellation, voluntary cancellation, voluntary cancellation of mitigation outcomes or ITMOs towards overall mitigation in global emissions, and use towards NDCs". It is important to note that the draft version of the agreed electronic format categorizes the processes of authorization, transfer, acquisition, and holdings as "actions". Parties are required to report any action that occurred within the reporting year. For instance, if a Party authorizes an ITMO in 2024, this authorization must be reported in the agreed electronic format by no later than April 15th, 2025, regardless of the ITMO's vintage.

The cooperative approach identifiers are issued by the UNFCCC secretariat through the Centralized Accounting and Reporting Platform (CARP), based on information provided by participating Parties in their reports under Article 6.2 (i.e., the Initial Report, Updated Initial Report, Annual Information in the Agreed Electronic Format (AEF), and Regular Information).

In practice, the secretariat typically assigns a new identifier to a cooperative approach upon submission of a Party’s Initial Report or Updated Initial Report, as the Annual Information and Regular Information are expected to refer to cooperative approaches that have already been described.

Each cooperative approach identifier follows an alphanumeric format (e.g., CAnnnn), with the numerical sequence (nnnn) assigned incrementally.

Preliminary checks performed BEFORE publication on the CARP

General

1. The Initial Report, Updated Initial Report and Regular Information are in a searchable PDF format (i.e., not a scanned copy or image-based PDF). The Annual Information (AEF) is in Excel format.
2. The report does not contain viruses.
3. All mandatory fields are completed. Where a section is not applicable, it is explicitly marked as “Not applicable” (N/A) or clearly indicates that it is intentionally left blank.
4. The report is a final version: no track-changes remain and all comments have been removed.
5. Hyperlinks in the report, if any (embedded or external), are functional, accessible, and direct to the relevant supplementary documentation.
6. The date and version of the report are clearly indicated on the first page, and reflect the actual submission date of the initial report.  The date follows the format dd/mm/yyyy and the version follows the format <major version>.<minor version>, with the version increasing upon re-submission.
7. The correct reporting template is used.

Cooperative approach

8. The name(s) of the cooperative approach(es) covered by the report are clearly indicated, and naming is consistent throughout the document.
9. Section IV (Chapters A–H) is completed and presented separately for each cooperative approach. Where multiple cooperative approaches are included, section IV must be distinctly separated for each cooperative approach to ensure that each receives its own unique cooperative approach identifier.

Authorization

10. Authorization information, when provided, refers unambiguously to a(n) (pre-)existing cooperative approach.
11. An Authorization Id is clearly mentioned, with the format 3 letter country code + 4 digits.

AEF

12. The structure of the AEF submission template has not been altered, i.e. all tables are present, and all fields are present.
