The Directive on public access to environmental information (2003/4/EC) is a European Union directive with the formal title "Directive 2003/4/EC of the European Parliament and of the Council of 28 January 2003 on public access to environmental information and repealing Council Directive 90/313/EEC".^[1][2]

The purpose of the Directive is to ensure that environmental information is systematically available and distributed to the public.^[3] The Directive requires Member States to ensure that public authorities are required to make the environmental information they hold available to any legal or natural person on request.^[3]

In 1998, the European Community signed a Convention on access to information, public participation in decision-making and access to justice in environmental matters (the Aarhus Convention).^[3] The directive implements the Convention.^[3]

Public authorities are required to release information on request subject to the following exceptions:^[4]

• the authority does not hold the requested information
• the request is manifestly unreasonable;
• the request is too general;
• the requested information is in the course of completion;
• the request concerns internal communications;
• the disclosure of the information would adversely affect:
  • the confidentiality of the proceedings of public authorities or of commercial or industrial information;
  • public security or national defence;
  • the course of justice;
  • intellectual property rights;
  • the confidentiality of personal data;
  • the interests of the person who supplied the information on a voluntary basis; or
  • the protection of the environment.
