The federal public authorities apply the 'access to environmental information' pillar of the Aarhus Convention by making their environmental information available to the public.

Public authorities have plenty of information on environment. This information is important to help everyone make choices, whether they be political, societal or individual choices. Therefore, the right to access to environmental information belongs to everyone (individuals, groups of citizens, associations, companies, etc…). 

The public authorities must make environmental information available to the public in two ways, so that the public can easily access this information:

  • On the one hand, as far as possible, they must disseminate the environmental information they have spontaneously on their websites (active advertising).
  • On the other hand, they must respond to written requests from citizens. 

Anyone can therefore approach a federal public administration and request any information it may have concerning the environment (passive advertising). This implies the possibility: to consult this information on the spot, to obtain explanations about it or to receive a copy. Moreover, it is not necessary to state an interest when requesting information.

The 'access to environmental information' pillar of the Aarhus Convention has been transposed at European level in Directive 2003/4/EC of the European Parliament and of the Council. The federal state transposed the Convention and the Directive into the Law of 5 August 2006 on public access to environmental information.
