2006 IPCC Guidelines for National Greenhouse Gas Inventories • Build on inventory development work by the IPCC and experience gained in using earlier IPCC guidance • Overview • Volume 1: General Guidance and Reporting • Volume 2: Energy • Volume 3: Industrial Processes and Product Use (IPPU) • Volume 4: Agriculture, Forestry and Other Land use (AFOLU) • Vol 5: Waste

2006 IPCC Guidelines for National Greenhouse Gas Inventories • Work of over 250 authors over 2 years • Update and expand earlier guidelines – Retaining consistency with earlier guidelines • Major improvements: – Improved accuracy: The guidelines include improved methods and updated default values. Emissions are estimated as actual annual emissions as opposed to the earlier “potential” methods. – More complete: Guidance on more sources/sinks and gases – Categories simplified and clarified (IPPU, AFOLU)

2019 Refinement to the 2006 IPCC Guidelines • The overall aim is to provide an updated and sound scientific basis for supporting the preparation and continuous improvement of national greenhouse gas inventories • Scope and outline approved by the IPCC at its 44 th Session (Oct. 2016, Bangkok, Thailand); Decision IPCC/XLIV-5 http: //bit. ly/2 Jt. ZJEf – The format should be one single Methodology Report comprising an Overview Chapter and five volumes following the format of the 2006 IPCC Guidelines – The title of the Methodology Report should be “ 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories”

2019 Refinement to the 2006 IPCC Guidelines • The refinement work will not revise the 2006 IPCC Guidelines, but will update, supplement and/or elaborate the 2006 IPCC Guidelines where gaps or out-of-date science have been identified • The 2019 Refinement will not replace the 2006 IPCC Guidelines, but will be used in conjunction with the 2006 IPCC Guidelines • Over 200 authors are working together to produce the 2019 Refinement to be completed in May 2019
