2019 Refinement to the 2006 IPCC Guidelines
 There are several refinements with a new and updated guidance in all sectors
 ENERGY -fugitive emissions, fuel transformation, etc. IPPU -hydrogen and rare earths production, electronics industry, etc. AFOLU -natural disturbances, flooded lands, etc. WASTE -solid waste disposal, wastewater treatment, etc. The general guidance contained in Volume 1 was also refined. Among others,Chapter 6 provides updated information on Verification, including guidance oncomparison with atmospheric observations.
 CMA noted that Parties may use on a voluntary basis the 2019 Refinement
under the Paris Agreement (Decision 5/CMA.3)

IPCC Expert Meeting on Use of Atmospheric Observation Data in Emission
Inventories - September 2022, Geneva, WMO

IPCC Expert Meeting on Atmospheric Observation Data
 The expert meeting aimed to discuss issues relating to the use of atmosphericobservation data and models in verification of national GHG inventories,
building on guidance provided in the 2019 Refinement
 The four areas of interest discussed were: CO2 emissions from fuel combustion
 Fugitive CH4 emissions
 AFOLU GHG emissions
 F-gases emissions
 The expert meeting brought different communities together – experts onatmospheric observation of GHGs, experts on inverse modelling and experts onnational emission inventories.

IPCC Expert Meeting on Atmospheric Observation Data Experts agreed, and Co-Chairs concluded, on usefulness of atmosphericobservation data for verification purposes in national GHG inventories as well ason the necessity to continue and further deepen conversation between inventory
experts and atmospheric scientists
 To ensure accuracy and purpose of comparison main challenges in the use ofatmospheric observation data remain: Identification and quantification of the anthropogenic component ofemissions and removals
 Attribution of GHG emissions/removals to NGHGI categories
 Geographically and/or temporally gridded NGHGI information, to ensure theappropriate spatial and temporal scales (with those of atmosphericobservation data)

IPCC Emission Factor Database (EFDB)

https://www.ipcc-nggip.iges.or.jp/EFDB/main.php

IPCC Emission Factor Database (EFDB) Library of emission factors/parameters and other relevant data that can be used
for estimation of national greenhouse gas (GHG) emissions/removals
https://www.ipcc-nggip.iges.or.jp/EFDB/main.php
 Default values from IPCC Guidelines
 Data from peer-reviewed scientific papers
 Data from other publications (e.g., government reports, industry studies etc.)
 Communication platform to share relevant data and information
 Evolves dynamically: data proposals (e.g., inventory compilers, researchers)
and data collection efforts (e.g., expert meetings, literature search) Open to any data proposals
 Continuously updated with new data

IPCC Emission Factor Database (EFDB) EFDB Meetings in 2022
 20th Editorial Board Meeting (28 June -1 July 2022, Bilbao, Spain) Joint 19th and 20th Expert Meeting on Data (29-30 June 2022, Bilbao, Spain)
 More than 600 data were accepted by Editorial Board for inclusion into theEFDB
 Upgraded version of the EFDB (both web and offline applications) will be
released next year before the AR6 cycle ends
 2019 Refinement categories are added Statistics tables are included Search/filter functions are enhanced (e.g., Select C pool, Region, Country
criteria are added for Basic search; static drop-down list is incorporated inSource of data column) Accordingly, the User Manual and the Data Entry Form are updated

Work on Short-lived Climate Forcers (SLCFs)
 At IPCC45 (March 2017) some governments proposed the work on
development of methodologies for estimation of emissions of Short-lived
Climate Forcers (SLCFs) and at IPCC46 (September 2017) it was decided
to hold an expert meeting on SLCFs to discuss issues on estimation ofemissions and climate effects (Decision IPCC/XLVI-6)
 The expert meeting was held jointly by TFI and WGI on 28-31 May 2018 inGeneva, Switzerland

Work on Short-lived Climate Forcers (SLCFs)
 The meeting concluded, among others: Science on SLCFs has significantly advanced since the IPCC expert
meeting held in 2005
 Improved emission inventories of SLCFs are necessary to enhancescientific understanding and assessment of their role in climate change aswell as to inform climate policy at national and international levels
 Internationally-agreed, globally applicable methodologies and emission
factors for SLCFs emission inventories are necessary, and the IPCC TFI isin a good position to do that work The meeting report is published at the IPCC TFI website:
https://www.ipcc-nggip.iges.or.jp/public/mtdocs/1805_Geneva.html

Work on Short-lived Climate Forcers (SLCFs)
 IPCC49 (May 2019) decided that IPCC TFI should develop a new Methodology
Report on SLCFs during AR7 cycle with a preparatory work during AR6 cycle(Decision IPCC-XLIX-7)
 Preparatory work for the Methodology Report in AR6 cycle included:
 Preliminary technical analysis
 Expert meetings (virtual): Joint 1st and 2nd Expert Meeting on SLCFs (11-22October 2021) and 3rd Expert Meeting on SLCFs (11-15 April 2022)
 Publication of the Expert meeting reports:
https://www.ipcc-nggip.iges.or.jp/public/index.html
 Scoping Meeting for the Methodology Report on SLCFs will be held during AR7
cycle in accordance with the agreement by the Panel at its 53-bis Session

Work on Short-lived Climate Forcers (SLCFs)
 IPCC TFI Technical Support Unit (TSU) conducted technical analysis of themain methodological frameworks on SLCFs source categories and associatedemissions: EMEP/EEA Air Pollutant Emission Inventory Guidebook 2019
 US EPA AP-42: Compilation of Air Pollutant Emissions Factors
 UNEP Atmospheric Brown Clouds (ABC) Emission Inventory Manual This analysis was the basis for discussion at the Joint 1st and 2nd Expert
Meeting. Working on the technical documents, this expert meeting successfully
achieved its goals:
 Complete list of SLCF source categories and associated SLCF species for all sectors – Energy,IPPU, AFOLU and Waste
 List of knowledge gaps

 All outcomes (category list, gaps’ list, BOGs’ discussion and conclusions, presentations
and tables for each sector) are part of the meeting report published at the IPCC TFIwebsite: https://www.ipcc-nggip.iges.or.jp/public/mtdocs/2110_SLCF.html

Work on Short-lived Climate Forcers (SLCFs)
 The 3rd Expert Meeting further considered issues identified at the Joint 1st and2nd Meeting and discussed cross-cutting issues in relation to the inventory ofSLCFs emissions taking into account the assessments in the IPCC WGI andWGIII contributions to AR6
 The discussion was focused on main three topics : Definitions of SLCF species and methods of their identification
 General inventory issues (Data Collection, Key category analysis,Uncertainty, Verification, etc.)
 Refined Category and Gaps’ list including issues related to the Category list
 The meeting report was published on the IPCC TFI website:
https://www.ipcc-nggip.iges.or.jp/public/mtdocs/2204_SLCF_EM3.html

Work on Short-lived Climate Forcers (SLCFs)
 The meeting reports and all background information will inform the scoping
process of a new Methodology Report on SLCFs during AR7 cycle
 The Scoping Meeting on the Methodology Report on SLCFs is planned to beheld in AR7 cycle as early as possible
 Nominations of experts for the Scoping Meeting will be collected from the IPCC
member governments and the observer organizations during AR6 cycle

Other Activities Technical support to users of the IPCC Guidelines and supporting tools:
 IPCC Inventory Software IPCC Emission Factor Database Collaboration with other organizations: UNFCCC regional workshops on the use of the 2006 IPCC Guidelines andthe IPCC Inventory Software Global Forest Observations Initiative (MGD 3.0)

Towards AR7 Cycle
During AR7, IPCC TFI is mandated to: produce a new Methodology Report on SLCFs emission inventory
Also, IPCC TFI is annually expected to :
 work on the IPCC Inventory Software maintenance and development
 work on IPCC EFDB management and update
 organize expert meetings relating to the IPCC Inventory Software, EFDB andother subjects relevant to national GHG inventories that may emerge
 cooperate with UNFCCC secretariat to provide training on the use of the 2006
