Application of the European Union Emissions Trading Directive : analysis of national responses under Article 21 of the EU ETS Directive (reported data in 2023)

Article 21 of the EU ETS Directive requires all EU ETS implementing countries to submit an annual report on the application of the Directive in their country by 30 June of each year ("the Article 21 reports" or "country reports" hereinafter). These Article 21 reports provide feedback on how a particular country has implemented the EU ETS Directive and underlying legislation. Countries complete their Article 21 report based on a questionnaire. An explanatory note supports the reporting by defining the objective of the questions and how each of the questions need to be completed. Submission of these country reports is done through an electronic system Reportnet 3, the e-Reporting platform hosted by the European Environment Agency. Article 21(2) of the EU ETS Directive requires the Commission to draft a technical report using the information from the Article 21 reports. This technical report describes how the various countries have implemented the different areas in EU ETS for the reporting year 2022. The countries covered are EU Member States, Liechtenstein, Iceland, Northern Ireland and Norway.
