Regulation (EC) No 223/2009 provides a reference framework for European statistics and requires Member States to comply with the statistical principles and quality criteria specified in that Regulation. Quality reports are essential for assessing, improving and communicating on the quality of European statistics. The ESSC has endorsed a European Statistical System (ESS) standard for Quality Reports Structure, in accordance with Article 12 of Regulation (EC) No 223/2009. That ESS standard should contribute to the harmonisation of quality reporting under Regulation (EU) 2018/1091. The Commission Implementing Regulation (EU) 2020/405 of 16 March 2020 specifies the arrangements for, and contents of, the quality reports to be transmitted under Regulation (EU) 2018/1091 of the European Parliament and of the Council on integrated farm statistics.
