All 43 Parties included in Annex I to the Convention (Annex I Parties) submitted their greenhouse gas (GHG) inventory common reporting format tables and national inventory reports in 2018. By the deadline of 15 April 2018, common reporting format tables and national inventory reports from 41 Parties had been received. Over the period 1990–2016 total aggregate GHG emissions without emissions and removals from land use, land-use change and forestry (LULUCF) for all Annex I Parties decreased by 13.0 per cent, while total GHG emissions and removals with LULUCF decreased by 18.5 per cent. For Annex I Parties with economies in transition, GHG emissions without and with LULUCF decreased by 37.6 and 49.6 per cent, respectively. For Annex I Parties that do not have economies in transition, GHG emissions without and with LULUCF decreased by 1.3 and 2.5 per cent, respectively. The information in this document is based on information in the national GHG inventory submissions of Annex I Parties received as at 31 August 2018. At the time of the publication of this document, the annual review process for GHG inventories from Annex I Parties was ongoing; therefore, the data included in this document may not reflect the latest information provided by Parties. The latest GHG inventory data are available on the UNFCCC website.
