EUETS.INFO relies on public data sources.

• European Union's Transaction Log (EUTL) is the major data source. We augment the original EUTL data in three major ways. First, we link transactions to the involved accounts. Second, we match former operator holding accounts to the respective installations. Finally, we eliminate duplicated account holders.

• Google Maps API is used to find the locations of installations using their address. The EUTL data include some information on latitude and longitude as well. This information is however rather incomplete and also shows some unreasonable entries. Therefore, we decided to geocoding by Google on the website. In the database, we include both, the EUTL and Google, location information.

• Leakage lists are used to infer the NACE sector classification of installations

• The matching to the Bureau van Dijk Orbis database is provided by the JRC.
