The Panel at its 49th Session in May 2019 adopted Decision IPCC-XLIX-7 that the IPCC Task Force on National Greenhouse Gas Inventories (TFI) should produce a Methodology Report on Short-lived Climate Forcers (SLCF).

Preparatory work for the Methodology Report is starting in the sixth assessment cycle and continue with further methodological development in the seventh assessment cycle.

Within the sixth assessment cycle, three to four expert meetings will produce a series of supporting materials which will inform a scoping meeting on the Methodology Report on SLCF. The scoping meeting will also take into consideration the work on SLCF that is already underway in the Sixth Assessment Reports of Working Group I and III.

The outline from the scoping meeting will then be presented to the Panel for approval.
