The European Commission is monitoring the implementation of EU legislation in the EU Member States to ensure that the laws achieve their intended objectives and that all countries of the EU respect the rules that have been agreed. The most common way of doing this is through reporting and monitoring. In other words, the EU Member States, based on their own internal monitoring, are submitting information and data to the European Commission which then analyses these national reports and presents its findings in various ways, in particular through:
People report on: state of the environment (e.g. air limit values, water status etc.), emissions (e.g. under European Pollutant Release and Transfer Register), pressures (e.g. under Marine Strategy Framework Directive), individual measures (e.g. under Nitrates Directive), plans and programmes (e.g. air quality management plans, river basin management plans etc.), market surveillance (e.g. under REACH), costs and benefits of the actions.
In general, environmental monitoring leads to data collection and reporting. Initially, monitoring may be undertaken by competent authorities, businesses, or other stakeholders. Data is often reported up a chain i.e. from stakeholder to competent authority to the European Environment Agency to the Commission, which may then in turn report to the European Parliament and the Council.
The European Commission (DG Environment) is often working together in close collaboration with Eurostat, the Joint Research Centre and the EEA or other agencies (e.g EFSA) depending on the legislation concerned.
The European Commission is keen to receive feedback on this subject matter. You can send any comments, questions or information of relevance (such as reports, projects, etc.) to us:ENV-E04@ec.europa.eu.
