In decision 6/CP.27 the deadline for the submission by Parties included in Annex I to the Convention (Annex I Parties) of their greenhouse gas (GHG) inventories due in 2024 was changed to 31 December 2024. This document was updated to include information on those Parties’ GHG emissions and removals for 1990–2022 based on the national inventory reports received from them as at 31 March 2025.

In 1990–2022, total aggregate GHG emissions without emissions and removals from land use, land-use change and forestry (LULUCF) for all Annex I Parties decreased by 19.5 per cent, while total GHG emissions and removals with LULUCF decreased by 26.1 per cent. For Annex I Parties with economies in transition, GHG emissions without and with LULUCF decreased by 44.6 and 64.0 per cent respectively. For Annex I Parties that do not have economies in transition, GHG emissions without and with LULUCF decreased by 8.8 and 10.7 per cent respectively.
