The Ruskensekretariat is a municipal administration unit in Oslo that works to promote a cleaner city. The office is involved in various initiatives and projects that aim to reduce littering and increase environmental awareness among citizens. Through collaborative projects with kindergartens and schools, the Rusken Secretariat contributes to engaging young people in clean-up campaigns and learning activities about environmental protection.
Among the well-known events are Vårrusken and Hunderusken, which gather volunteers to clean up the city spaces.
