How often are the GHG data updated?
Starting from 2010, the information presented on this website is updated three times a year: the first update is released in March to include resubmissions of Annex I GHG inventories for the previous year; the second one (which is the major update) in June/July to provide access to data from the annual submission of Anex I GHG inventories due by 15 April; the third update in September/October to include changes in Annex I data, if any. Non-Annex I GHG data are reported in national communications, which are submitted at different points in time. Therefore, along with the update of Annex I Parties’ data, available non-Annex I data are updated as well. The data from external sources, such as population and GDP data, are revised during the major update (June/July), provided that they have been revised by the United Nations and the World Bank (for example, population data are updated once every two years).
