2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories

The development of the Methodology Report to refine the inventory guidelines (2006 IPCC Guidelines for National Greenhouse Gas Inventories), was carried out by the Task Force on National Greenhouse Gas Inventories (TFI) in accordance with the decision taken at the 44th Session of IPCC in Bangkok, Thailand, in October 2016. The final draft of this Methodology Report titled “2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories” (2019 Refinement) was adopted/accepted by the IPCC at its 49th Session on 12 May 2019. Its overall aim is to provide an updated and sound scientific basis for supporting the preparation and continuous improvement of national GHG inventories. The 2019 Refinement will not revise the 2006 IPCC Guidelines, but update, supplement and/or elaborate the 2006 IPCC Guidelines where gaps or out-of-date science have been identified. It will not replace the 2006 IPCC Guidelines. It should be used in conjunction with the 2006 IPCC Guidelines.
