Session 5: Implications of Outcomes from
COP26 on further Refinement of the IPCC
Inventory Software
8 June 2022
IPCC TFI TSUOverview
 Upgrades to IPCC Inventory Software to support Paris
Agreement implementation, include, among others, facilitatinginteroperability with one of the reporting tools referred to in
UNFCCC decision 5/CMA.3.

What is therelationship between
the IPCC inventory
software and Paris
Agreement reporting?

What is“interoperability?”

The road ahead…

Background Beginning 31 December 2024, countries submit a biennial transparency
report (BTR) consisting of 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 theelectronic reporting of the tables and formats, specifically:
 Common reporting tables for GHG inventory (Annex I);
 Common tabular formats for tracking progress made in implementing/achieving
NDCs (Annex 2);
 Common tabular formats for financial, technology development and transfer andcapacity-building support (Annex 3)

 Requests the UNFCCC to facilitate interoperability between the reporting
tools and the IPCC inventory software and invites the IPCC to participate ineffort.

“The ability of computer systems or software to exchange and make use of information”--Oxford Dictionary

Parties may use IPCC inventory software to calculate GHG emissions/removals
IPCC inventory software “speaks” to the UNFCCC reporting toolSoftware generates an output file (e.g. XML) that could be input to the UNFCCC
GHG inventory reporting toolData contained in the IPCC inventory software rearranged/mapped to fit the agreed
GHG inventory reporting tables in 5/CMA.3. (Annex I)

Party QC’s the final tables generated by the UNFCCC reporting tool, and makes
formal submission using the UNFCCC tool.

Importance of interoperability
IPCC inventory software becomes a central component of a Party’s
institutional arrangements to facilitate meeting UNFCCC national reportingobligations.
 Supports Parties in calculating GHG emissions/removals
 Minimizes error Organizing framework for data collection efforts among entities
 Enhances transparency
 Reduces reporting burden

The road ahead…
All are working together to implement

Key messages
 The IPCC inventory software is a robust and flexible tool to support countries in
preparing a GHG inventory Upgrades are underway to facilitate its use for calculating GHG emissions inaccordance with the MPGs IPCC TFI TSU is working closely with UNFCCC to facilitate interoperability
between tools in the context of the invitation from the CMA (decision 5/CMA.3)
