Why do we need GHG inventory guidelines?
• The world is committed to reducing net GHG
emissions to tackle climate change.
• We cannot reduce what we cannot measure.
We need to know how many net GHG emissions
we are producing and what are the activitiesproducing them.
• The IPCC inventory guidelines enable allcountries to estimate level and trends of GHG
emissions and removals across the entire
territory using agreed methods, taking intoaccount the activities from which those source.
This is what GHG inventories do.

New Supplementary Guidance in 2013

IPCC Inventory Guidelines
and UNFCCC＋Currently, Non Annex I Parties use theseunder the UNFCCC.

Non-Annex I Parties are encouraged
to use GPGs.

1995 IPCC
Guidelines

GPG2000(non-LULUCF)

GPG2003(LULUCF)

Annex I Parties must usefrom 2015
All Parties will use underthe Paris Agreement
2006 IPCC
Guidelines

Revised 1996 IPCC
Guidelines

Actually, 2006 Guidelines are being usedby more and more Non-Annex I Parties.
Revision/Update by the IPCC

Paris Agreement and National GHG Inventory• In order to build mutual trust and confidence among the Parties
and to promote effective implementation of the Paris Agreement,a transparency framework for action needs to be enhanced.
• To that end, it is essential that all the Parties produce and reporthigh-quality and reliable national GHG inventories (nationalemission data).
• Paris Agreement
Article 13, paragraph 7:– Each Party shall regularly
provide …:(a) A national inventory
report of anthropogenic
emissions by sources andremovals by sinks ofgreenhouse gases,
prepared using good practice methodologies accepted

by the Intergovernmental Panel on Climate Change and…

2019 Refinement to the 2006 IPCC
Guidelines for National Greenhouse Gas
Inventories
Provides an updated and sound scientific basis to support good practices forthe preparation and continuous improvement of national greenhouse gas
inventories.

2019 Refinement to the 2006 IPCC Guidelines• 2006 IPCC Guidelines – 13 years ago!!
• The 2006 IPCC Guidelines continue toprovide a technically sound methodologicalbasis for preparing national greenhouse gas
inventories.
• The 2019 Refinement updates,supplements and elaborates those where
the authors identified gaps or out-of-datescience.
• The 2019 Refinement is to be used inconjunction with the 2006 IPCC Guidelines.

IPCC procedures for producing the 2019 Refinement

2019 Refinement was adopted/accepted by the IPCC
at its 49th Session in May 2019 in Kyoto, Japan.
(Decision IPCC-XLIX-9)

2019 Refinement to the 2006 IPCC Guidelines
280

Prepared by over 280 scientists and experts

4710,000Participated by authors from 47 countries

More than 10,000 review comments fromgovernments and experts were considered by authors

Produced as one of the major IPCC products during its AR6 cycle.

Structure of 2019 Refinement• The same structure as that of the 2006 IPCC Guidelines soas to make it easier for inventory compilers to use the 2019
Refinement with the 2006 IPCC Guidelines.
• Comprising an Overview Chapter and five volumes:– Vol.1: General Guidance and Reporting (GGR)– Vol.2: Energy– Vol.3: Industrial Processes and Product Use (IPPU)– Vol.4: Agriculture, Forestry and Other Land Use (AFOLU)– Vol.5: Waste• Glossary is also included.

General features
Emissions factors and other parameters updatedbecause refined estimates (more and better data available to calculateaverages)

 technological/environmental changes

Clarification of guidance through Additional examples
 Clearer reasoning Additional information on good practice Additional excel-based tools

General Guidance
New guidance on• Implementation of a national inventory management system(institutional arrangements structuring, roles and capabilities of actors andstakeholders, data flows and suggested contents of Data Supply Agreements,
work plans, improvement plans, data management systems, quality system)• Development of country specific emission factors• Integration into NGHGI of emissions reported from facilities• Non-linear interpolation• Use and reporting of models

General Guidance
Updated guidance on• Data Collection• Comparison with atmospheric measurements• Indirect CO2 inputs to the atmosphere

Clarification on• uncertainty calculation (uncertainty in the mean vs in the individual;
Stepwise use of Monte-Carlo analysis; Tier 1 Uncertainty calculation tool)•key category analysis

Energy
Additional guidance on• Fugitive CO2 emissions from underground and surface mines• Fugitive emissions from oil and natural gas systems including
unconventional oil and gas

New guidance on• Fugitive emissions from fuel transformation (charcoal and biochar
production, coke production and gasification transformation processes - coal
to liquids and gas to liquids)Industrial Processes and Product Use
New guidance on• Production of: Hydrogen, Rare Earth Metals, Alumina• Water-proofing of electronic circuit boards

Updated guidance on• Production of: Nitric acid, Fluorochemical, Iron & Steel,Aluminium• Electronic industry• Refrigeration and air conditioning

Worksheet for Tier 2 calculation: refrigerants (MS Excel)

Agriculture, Forestry and Other Land UseNew guidance on•

WasteUpdated guidance on• New types of managed solid waste disposal sites• CH4 and N2O emissions from gasification and pyrolysis of waste• CH4 and N2O emissions from wastewater

New guidance on• N2O emissions from industrial wastewater2019 Refinement and Paris Agreement• “Katowice Climate Package” was adopted by theUNFCCC COP24/CMA1 in December 2018 tooperationalize the Paris Agreement. It stipulates:– Each Party shall use the 2006 IPCC Guidelines, andshall use any subsequent version or refinement of theIPCC guidelines agreed upon by the Conference of theParties serving as the meeting of the Parties to theParis Agreement (CMA).
The 2019 Refinement is nothing but
this “subsequent version orrefinement of the IPCC Guidelines”!!
