National Greenhouse Gas Inventories• National Greenhouse Gas Inventories are essential totransparent MRV system under the UNFCCC• UNFCCC: Article 4, paragraph 1– All Parties, …, shall:(a) Develop, periodically update, publish and make available to theConference of the Parties, in accordance with Article 12, national
inventories of anthropogenic emissions by sources and removals bysinks of all greenhouse gases not controlled by the Montreal
Protocol, using comparable methodologies to be agreed uponby the Conference of the Parties;• Paris Agreement: Article 13, paragraph 7– Each Party shall regularly provide the following information:(a) A national inventory report of anthropogenic emissions bysources and removals by sinks of greenhouse gases, preparedusing good practice methodologies accepted by theIntergovernmental Panel on Climate Change and agreed uponby the Conference of the Parties serving as the meeting of theParties to the Paris Agreement;

Revision/Update by the IPCC

2006 IPCC
GuidelinesNeed for Refinement of 2006 IPCC
Guidelines• More than 10 years have passed since 2006.

• TFI Bureau (TFB) at its 26th meeting in 2014 concluded: 2006 IPCC Guidelines provide a technically sound methodologicalbasis of national greenhouse gas inventory, and therefore
fundamental revision is not necessary
 However, certain refinements may be required, taking into accountscientific and other technical advances that have matured sufficiently
since 2006

• IPCC at its 44th Session (17-20 October 2016, Bangkok,Thailand) decided to prepare a Methodology Report torefine the 2006 IPCC Guidelines (Decision IPCC/XLIV-5)– “2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas
Inventories” (2019 Refinement)• During its 44th Session, the Panel approved the outline of
the 2019 Refinement (Decision IPCC/XLIV-5)

Objectives of 2019 Refinement• The overall aim of the refinement of the 2006 IPCC
Guidelines is to provide an updated and soundscientific basis for supporting the preparation andcontinuous improvement of national greenhouse gas
inventories• The refinement work will not revise the 2006 IPCC
Guidelines, but will update, supplement and/or
elaborate the 2006 IPCC Guidelines where gaps orout-of-date science have been identified• The 2019 Refinement will not replace the 2006 IPCC
Guidelines, but will be used in conjunction with the2006 IPCC Guidelines

Coverage and Structure• Coverage: All IPCC inventory sectors are covered butrefinements are included for only those categories wherethe science is considered to have sufficiently advanced
since 2006 or where new or additional guidance isrequired• Structure: Same as that of the 2006 IPCC Guidelines soas to make it easier for inventory compilers to use the2019 Refinement with the 2006 IPCC Guidelines
