The European Court of Auditors adopted Decision 6-2019 on the open data policy and the reuse of documents with the objective of improving the flow of information between the ECA and the general public, and to facilitate the widespread reuse of information (Article 1).​

In this context, the ECA committed to making documents in its possession available on the internet in open and machine-readable formats, wherever possible and appropriate.

The reports included in this section have been published together with datasets produced in accordance with the ECA's open data decision. Information on the data presented in the report is also published, including, where possible, the data sources and the methodologies and calculations applied.

Open data originating from the ECA are also available through the EU Open Data Portal on data.europa.eu, together with datasets from other EU institutions, bodies and agencies and from EU Member States.
