29th Meeting of the Bureau of the Task Force on National Greenhouse Gas Inventories
29 September 2017,Victoria Falls, Zimbabwe
Summary of the meeting
The 29th Meeting of the Bureau of the Task Force on National Greenhouse Gas Inventories (TFB) was held on 29th
September 2017, in Victoria Falls, Zimbabwe, back-to-back with the Second Lead Author Meeting (LAM2) for theElaboration of the 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2019Refinement) held on 25-28 September 2017. The meetings were hosted by the Government of Zimbabwe andorganised by the Technical Support Unit (TSU) of the Task Force on National Greenhouse Gas Inventories (TFI).
The agenda of the 29th meeting of TFB was as presented below.
One of the main objectives of the 29th meeting of TFB was to consider milestones towards preparation of 2019
Refinement first-order draft (FOD) and issues raised at LAM2.
In particular, TFB pointed out that the default EFs should not be updated if significant discrepancy is not observed withthe 2006 IPCC Guidelines as stipulated in the TOR. However, there may be exceptional cases where even such
updates are considered necessary, e.g. in cases where new technologies are introduced. In such cases, Lead Authors
should be encouraged to do their best in developing new default EFs in consultation with the Steering Group (SG). It
was also noted that there is a need to have a transparent approach in documentation of data sources, and to document
how the default EFs have been derived. In addition, TFB agreed that there is a need for clarity and a common
understanding of how the information on EF data and data sources will be archived by TSU.
Regarding the work on the short-lived climate forcers (SLCF), TSU highlighted the decision taken at the 46th Sessionof the IPCC in Montreal, Canada in September 2017, and informed TFB that an expert meeting would be held on 2831 May 2018 in Geneva to discuss issues on estimation of emissions as well as of climatic effects (direct and indirect
effects on radiative forcing, including implications on clouds). It was agreed that TFI should lead the process oforganizing the expert meeting although it would be held jointly by TFI and Working Group I.
TFB was invited to consider whether it would be necessary to revise the work plan and budget for 2018-2020. In
response, no specific suggestion was made by TFB. TFI Co-Chairs announced that countries are encouraged to donate
to the IPCC Trust Fund.
Regarding the Emission Factor Database (EFDB), TSU reported that the terms for 16 out of 36 Editorial Board members
would expire at the end of 2017 and for other 5 members the terms would expire at the end of 2018. Therefore,
nominations of experts by governments and observer organizations for 21 positions falling vacant at the end of 2017and 2018 would be requested within this year.
TSU informed TFB that the development of Tier 2 worksheets for land-use category in the IPCC Inventory Software willstart subject to confirmation of availability of necessary funds, and that the development of Tier 2 worksheets for 3A
and 3C categories was currently under way. TFB requested TSU to consider implementation of 2019 Refinement into
the IPCC Inventory Software upon its completion.

Regarding the cooperation with UNFCCC Secretariat, TFB was informed that TSU this year participated in one regional
workshop for Africa conducted by the UNFCCC Secretariat while it did not participate in the other one for Latin Americaand Caribbean region.
TFB took note of the report made by TSU on the errors and corrigenda for TFI Methodology Reports, and requested
TSU to continue making efforts to address the identified errors.
