The partnership was led by two of the largest ZOOs in the cross-border area, one of them in Pécs and the other in Osijek. Their joint goal was to research the possibilities of a more environmentally friendly approach to their services through the purchase of energy efficient and waste-reducing equipment as well as development of educational materials for informal education of kindergarten and school children and the organisation of workshops and conferences focusing on environmental issues. The main target group were children and youth and the ZOOs were used as open space educational spaces.
