Notes on GHG data

The GHG data interface includes GHG data received by the UNFCCC secretariat as of 18 February 2022.
Data displayed on the data interface are "as received" from Parties. The publication of Party submissions on this website does not imply the expression of any opinion whatsoever on the part of the UNFCCC or the Secretariat of the United Nations concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries as may be referred to in any of the submissions.
The reporting and review requirements for GHG inventories are different for Annex I and non-Annex I Parties. Annex I Parties report their GHG inventories annually by 15 April, whereas non-Annex I GHG data are reported in national communications and biennial update reports, which are submitted at different points in time.
The long dash (---) means that data is not available.

As per decisions 9/CP.2 and 11/CP.4, some of the Parties are allowed to use a base year other than 1990. These Parties and their base years are: Bulgaria (1988), Hungary (average of 1985-1987), Poland (1988), Romania (1989) and Slovenia (1986).
Annex I Parties report GHG data in the common reporting format (CRF) tables. The CRF data prepared using the CRF Reporter are readily available for import into the UNFCCC data warehouse. Non-Annex I Parties however do not use the CRF Reporter software because of the difference in reporting requirements and therefore the GHG data reported by non-Annex I Parties need to be processed manually before the data reported can be imported into the UNFCCC data warehouse and displayed as part of the GHG data interface.
Some of the source categories under the industrial processes sector have unique country specific activity data depending on the national circumstances. For such source category, the data interface does not provide description of activity data and is noted by the generic term 'activity data'. However, the details on the description of the activity data can be found in the CRF tables reported by the respective Parties.
The definition format of data for emissions/removals from the forestry sector is different for Annex I and non-Annex I Parties. For Annex I Parties, the sector is called Land Use, Land-use Change and Forestry (LULUCF) whereas for non-Annex I Parties, it is called Land-use Change and Forestry (LUCF). These two definitions are close but not equivalent.
Emission estimates of the 28 member States of the European Union are reported separately from those of its individual member States. These estimates are not included in the Annex I total in order to avoid double counting.
The GHG inventory submitted by Sierra Leone for the period 1990-2005 appears to contain technical errors, especially for the Agriculture and LUCF sectors. Therefore, information from this inventory is currently not included in the data interface.
Chile reported CO2 emissions for the agriculture sector: 203.4 Gg for 1990, 241.7 Gg for 1994, 366.5 Gg for 2000, 470.1 Gg for 2010, 509.3 Gg for 2013, 445.4 Gg for 2016, and 440.8 Gg for 2018. These values are included in the national total GHG emissions but could however not be displayed separately for the agriculture sector's CO2 emissions.
Some non-Annex I Parties submitted their GHG inventory data using the format of the 2006 IPCC Guidelines in reporting GHG emissions/removals. For this reason, these data could not be included in the data interface. However, the data are available in the national communications (Andorra, Angola, Antigua and Barbuda, Armenia, Azerbaijan, Bahrain, Bangladesh, Bhutan, Brazil, Brunei Darussalam, Cabo Verde, Cook Islands, Costa Rica, Côte d'Ivoire, Colombia, Cuba, Equatorial Guinea, Eswatini, Fiji, Gabon, Gambia, Georgia, Grenada, Ghana, Honduras, Indonesia, Iran, Jamaica, Kuwait, Lesotho, Malaysia, Mauritania, Mauritius, Mexico, Mongolia, Montenegro, Morocco, Namibia, Nepal, Nicaragua, Nigeria, Panama, Oman, Republic of Moldova, Rwanda, Samoa, Serbia, Sierra Leone, Singapore, Somalia, South Africa, Suriname, Timor-Leste, Trinidad and Tobago, United Arab Emirates, Vanuatu, Venezuela, Viet Nam, and Zambia) and biennial update reports (Afghanistan, Albania, Andorra, Antigua and Barbuda, Argentina, Armenia, Azerbaijan, Belize, Benin, Cambodia, Chile, Colombia, Costa Rica, Côte d'Ivoire, Dominican Republic, Egypt, El Salvador, Gabon, Ghana, Georgia, Guinea-Bissau, Honduras, India, Indonesia, Jordan, Laos Peoples Republic, Lesotho, Liberia, Malaysia, Mauritania, Mauritius, Mexico, Mongolia, Montenegro, Morocco, Namibia, Nigeria, North Macedonia, Oman, Panama, Paraguay, Papua New Guinea, Peru, Republic of Moldova, Rwanda, Saint Lucia, Serbia, Singapore, South Africa, Tajikistan, Thailand, Togo, Trinidad and Tobago, Tunisia, Uruguay, Uganda, Uzbekistan, Viet Nam, and Zambia
The UNFCCC data interface contains some data on country area, population and gross domestic product (GDP), which are shown to illustrate the national context for GHG emissions/removals. The source of the population data is the UNSD Demographic Statistics but data are accessed through the Common Database of the United Nations Statistics Division; the source of the GDP data (at market prices, constant 2010 US$) is the World Bank. These data are displayed on the GHG data interface with the kind permission of the United Nations and the World Bank; the United Nations and the World Bank have regulations concerning the use of their data and these organizations must be consulted before downloading population and GDP data for further use. The country area data is taken from the Statistical Database of the Food and Agriculture Organization of the United Nations (FAO).

Under the Kyoto Protocol, Annex I Parties that are also Parties to the Kyoto Protocol with commitments inscribed in Annex B to the Kyoto Protocol (Annex B Parties) should submit a national GHG inventory, as required under the Convention, as well as supplementary information on its implementation of the Kyoto Protocol that covers the Party's holdings and transactions of Kyoto Protocol units (for the previous year), and emissions and removals from land use, land-use change and forestry (LULUCF) activities under Article 3, paragraphs 3 and 4, of the Kyoto Protocol.
For the first commitment period, information is presented for 37 Annex B Parties. For the second commitment period, information is presented for 35 Annex B Parties that have ratified the Doha Amendment. Belarus, Kazakhstan and Ukraine have not ratified the Doha Amendment.
For the first commitment period, data presented on the data interface are based on the information reported and reviewed after the first commitment period and the additional period for fulfilling commitments (true-up period).
For the second commitment period, data presented on the data interface are based on the latest submissions of annual GHG inventory and transactions and holdings of Kyoto Protocol units as at 18 February 2022.
For the first commitment period, data of the European Union (15) are included in the calculation of the totals for Annex B groups (i.e. Annex B and Annex B non-EIT), and data of individual member States are excluded, to avoid double counting.
For the second commitment period, data reported by the European Union are included in the calculation of the totals for Annex B groups, and in order to avoid double counting, data of the 27 member States, Iceland and the United Kingdom have been excluded.
For the second commitment period, the assigned amount of the EU (15,813,089,338 t CO2 eq) is the difference between (1) the joint assigned amount of the EU, its member States and Iceland, equaling 80 per cent of their base-year emissions as inscribed in the third column of Annex B in the Doha Amendment, multiplied by eight (37,604,433,280 t CO2 eq), and (2) the sum of the individual assigned amounts of the 27 member States, Iceland and the United Kingdom (21,791,343,942 t CO2 eq) determined in line with the terms of the joint fulfillment agreement.
