European Environment Agency
Directive 2003/87/EC (EU, 2003) of the European Parliament and of the Council of the European Union (EU) established the EU Emissions Trading System (EU ETS), which is a key EU policy instrument aimed at reducing greenhouse gas emissions.
Article 21 of the EU ETS Directive stipulates that, each year, Member States should report on the application of the Directive. These reports should be based on
the ‘Article 21 questionnaire’, which was adopted by the European Commission in Implementing Decision 2014/166/EU (EU, 2014a).
Article 21 further stipulates that, on the basis of the Member States’ reports, the Commission should publish a report on the application of this directive. This
document serves as input in this regard.
This EEA report considers whether or not the implementation of this directive is on track, if there is potential for improvement in certain areas and whether or not further information is required to determine the status of implementation.
