In 2016, the European Commission initiated an evaluation of the European Environment Agency (EEA) and its European Environment Information and Observation Network (EIONET) through the publication of an Evaluation Roadmap. This evaluation follows the Better Regulation Guidelines and thus includes analysis of five main themes: Effectiveness, efficiency, relevance, coherence and European added value. The scope of the evaluation covers all the work of the EEA and EIONET in the period mid-2012 until end-2016. The Commission produced its Evaluation Report SWD(2018)470 on 20 November 2018. The European Commission contracted a consortium led by COWI to undertake a study to support the evaluation.
