Citizens’ Commitment

The UN Conference on Environment and Development in Rio de Janeiro adopted Agenda 21 in 1992. Local authorities were thus given a key role in implementing sustainable development. Signing the Aalborg Charter for sustainable development in 1996, Freiburg‘s efforts for greater sustainability were shaped primarily by Local Agenda 21.


„You only see what you‘re aware of, and you only protect what you know.“ The slogan for Freiburg‘s Nature Trail is as valid as ever – after all, environmental protection and nature conservation have to offer specific experiences and direct, hands-on adventures if they are to be successful.
