Pupils from the Ernst Reuter School in Karlsruhe meet with museum staff, the Greenpeace "Schools for Earth" team and experts from the Institute for Energy and Environmental Research Heidelberg (ifeu) at the ZKM (Center for Art and Media) for a day-long workshop. It is the start of a close exchange process. Together, the group discusses climate-relevant emission areas of the school and the museum and also develops concrete climate protection measures.
