UNFCCCElectronic
Reporting Tool

Background✓ Beginning 31 December 2024, countries submit a biennial transparency report (BTR) consistingof a narrative document and reporting tables/ formats.
✓ Reporting must follow the Modalities, Procedures and Guidelines (MPGs) (decision 18/CMA.1).
✓ Decision 5/CMA.3 mandates the UNFCCC to develop reporting tools for the electronic reporting of
the tables and formats, specifically:✓ Common reporting tables (CRT) for GHG inventory (Annex I);✓ Common tabular formats (CTF) for tracking progress made in implementing/achieving NDCs (Annex 2);✓ CTF for financial, technology development and transfer and capacity-building support (Annex 3)✓ Decision 5/CMA.3 requests the UNFCCC secretariat to facilitate interoperability between thereporting tools and the IPCC Inventory Software and invites the IPCC to participate in this effort.

Interoperability: What it is and why it is important?
Interoperability: “The ability of computer systems or software to exchange and make use ofinformation” -Oxford Dictionary✓ In practice, the goal is to enable a country to use the IPCC Inventory Software to estimate its GHG
emissions and removals in accordance with the 2006 IPCC Guidelines and generate a file that could bereceived and read by the UNFCCC reporting tool for CRT to facilitate the country’s reporting to theParis Agreement.
✓ Thereby, IPCC Inventory Software becomes a central component of a Party’s institutionalarrangements to facilitate meeting UNFCCC national reporting obligations.

burdenUNFCCC and IPCC cooperation to achieve interoperability
Step 1: Mapping between IPCC Inventory Software and CRT✓ For all categories, tiers and gases, map where
they should appear in the UNFCCC CRT✓ In some cases, this has required updatesto the IPCC Inventory Software (e.g.
2019 Refinement, additional gases)✓ Coordination with UNFCCC toensure correct mapping

UNFCCC and IPCC cooperation to achieve interoperability• Step 2: Cell-by-cell mapping between IPCC Inventory Software and CRT,
implementing visualization of CRT in IPCC Inventory Software✓ For Sectoral / Background CRT, ADand emissions map from IPCC
Inventory Software to CRT; IEF andsummary tables calculated in CRT✓ Additional explanatory information
can be added in IPCC Inventory
Software (e.g. documentation boxes,
user/ Party comments, method/EFinformation, notation key explanations,
including confidentiality)

What can users expect for version with interoperability?
Step 1. User calculates annual/ time series of GHG Inventory in IPCC InventorySoftware✓ Interface will look the same as current version, with some updated categories/
gases to facilitate interoperability.
Step 2. Access CRT interface in the Main
Menu of IPCC Inventory Software- Create / name the CRT data set tobe generated- Select the year(s) for export to CRT- Feed worksheet data into CRT
visualized in IPCC Inventory Software
Note: Some images may be updated as we continue to finalizeinteroperability, taking into account comments received.

Step 4. Finalize information for export to CRT – treatment of confidential information✓ In cells containing values, the only notation key is C (Confidential) allowing a user to mark that CRT Variable as“Confidential”. A “C” flag is added as a suffix to the numeric value. While the value in the confidential cell is stillvisible in the software it will not be exported to CRT✓ If issues are identified during the finalization phase, user may toggle to IPCC Inventory Software worksheets, andaddress issue. Selecting “Refresh value” will update view in CRT visualization tables

The Road Ahead✓ Multiple releases between now and COP28, and beyond to June
2024, are expected.

June2023✓ The best way for Parties to prepare for reporting under the ETF, isto start today.
