The Independent Institute for Environmental Issues, UfU e.V., had the pleasure to invite highly ranked scholars from different jurisdictions and members of national and international authorities to an exchange on ‘Best Practices on Access to Environmental Information’ in Berlin, the 3rd of December 2018. This international Symposium was carried out on behalf of the German Federal Environment Agency (UBA) and the German Federal Ministry for the Environment, Nature Conservation and Nuclear Energy. It is integrated into a broader interdisciplinary evaluation process of the German Access to Environmental Information Act. Non-judicial mechanisms, such as mediation processes or the role of advisory bodies, as well as the practice of private bodies and their obligation to provide access to environmental information ranged among the discussed topics.
