The EU ETS data viewer offers easy access to emission trading data from the European Commission’s Union Registry website (previously European Union Transaction Log, EUTL). The Union Registry is the Commission’s online database that helps ensuring accurate accounting of allowances issued under the EU ETS. The EU ETS data viewer provides aggregated data by country, by main activity type and by year on the verified emissions, allowances and surrendered units. The data reported under the EU emission trading system cover more than 16000 stationary installations, 1600 aircraft operators and 2600 maritime operators.

Background material:
The EU ETS data viewerdata quality note gives insights in the quality control checks performed by the European Topic Centre on Climate Change Mitigation (ETC-CM).
The EU ETS data viewer background note provides more information on the ETS data.
The ETC-CM'stechnical report (scope estimate update 2023) outlines the methodology of the estimates of 2005-2020 emissions for stationary installations to reflect the 4th trading period scope (2021-2030) of the EU ETS.
Allowances auctioned or sold (EUAs and EUAAs) (1.3)
Data based on auction calendars and auction results published by the auctioning platforms for emission allowances in the EU ETS.
Scope estimates 2005-2012:
The EEA produces estimates of emissions and allowances for 2005–2012 in order to reflect the current scope of the EU ETS. This is because the scope of the EU ETS has evolved since it was created in 2005 (inclusion of new countries, activities and gases), therefore the trends in emissions and allocated allowances directly based on the EUTL are not fully consistent over time. Taking into account these estimates is relevant for trend analyses over several years, in particular across trading periods.
Additional information
The ETS information 1. Total allocated allowances, 1.2 Correction to freely allocated allowances (not reflected in EUTL), 1.3 Allowances auctioned or sold are only available at national level. The data can be split between aviation (activity type 10) and stationary installations (activity types 20-99). No further split by activity type is possible. These data are therefore only presented when the following parameters are selected:
EU ETS information: “10 Aviation” or “20-99 All stationary installations" (default selection)
Size: "All sizes" (default selection)
Active entity: "All entities" (default selection)
The list of countries includes NER 300 auctions. This is to reflect the auctioning, at EU level, of a certain number of allowances, as part of the "NER 300" funding programme for innovative low-carbon energy demonstration projects. These allowances are visible when selecting “NER 300 auctions” in the category “Country”.
The ETS information on surrendered units is available by type of units (4.1 (EUAs and EUAAs), 4.2 (CERs) and 4.3 (ERUs)) until 2012. From 2013 onwards, only the total of surrendered units (4) is available.
The information on the type of activity of the entities covered by the EU ETS is based on the EUTL classification (which differs from UNFCCC nomenclature for greenhouse gas emission source categories or NACE codes). It was further harmonised by the EEA, in order to merge activity type codes used in the first and second trading periods (and still used by a significant number of installations) with new activity type codes formally in use in the current trading period. This harmonisation was carried out on the basis of additional information available on the actual activity of installations.
