IPCC Inventory Softwareo IPCC Inventory Software was produced in 2012. Initially, it was designed to be a simple
tool implementing only Tier 1 methods according to the 2006 IPCC Guidelines
o The latest version is the version 2.861. It has been released on June 6, 2023 at the SB 58
o The version 2.861 implements the following:• all Methodological Tiers & Approaches according to the 2006 IPCC Guidelines, and its✓Wetlands Supplement (in lilac colour)✓in addition, some elements of the 2019 Refinement (in magenta colour) to facilitate
Interoperability with the UNFCCC CRT Reporting tool

• Interoperability functionality with the UNFCCC CRT Reporting tool (Energy Sector)

Version 2.861
o More features• allows subnational level of reporting (e.g., tracking specific activities or regions)• allows for each source/sink to use either a single methodological Tier or a mix of Tiers• allows, in each equation, to input user-specific values for EFs and parameters• allows different categories/sectors to be developed simultaneously• implements AR5 GWP100 values (and allows any other user-specific metric to be applied)• stores the entire set of information of NGHGI within a single database

category by implementing all methodological Tiers & Approaches according to the 2006
IPCC Guidelines and its Wetlands Supplement with elements of the 2019 Refinement.
o Software users must be familiar with the IPCC methodologies and read the Software
Manual (downloadable from the “Help” menu) before going through the Guidebook.
✓ The Guidebook does not replace guidance provided in the IPCC Methodology Reports

Supporto IPCC TFI TSU is supporting the IPCC Inventory Software:• User Manual• Help Desk: ipcc-software@iges.or.jp• Pool of voluntary testers, to support software development and use• Cooperation with the UNFCCC at training workshops on the use of the IPCC InventorySoftware• Annual IPCC meetings on feedback from software users, including issues where support
is needed or software improvements are envisaged✓ In the 7th IPCC assessment cycle (from end of July 2023) the plan and support may be subject to changes, depending
on consideration by the IPCC and the new Bureau of the Task Force on National Greenhouse Gas Inventories
