The project investigates the possibilities of making school kitchens more climate and energy efficient. The main starting points are food selection, kitchen equipment, and process optimisation. Upstream and downstream processes such as the provision of food and the disposal of organic waste will also be investigated. 24 all-day schools in the Cologne area are part of the project as practical partners.

ifeu is responsible for drawing up the status quo greenhouse gas and energy balances for the 24 all-day schools. Based on this, ifeu derives optimisation potentials, prepares school-specific catalogues of measures to increase climate and energy efficiency and quantifies the successes in practice following the implementation test.

In order to take account of the other pillars of sustainability, the costs of the menus and health aspects are also analysed, e.g. by complying with recommendations by the German Nutrition Society (DGE). The project also focuses on the identification of barriers and the development of practical aids such as an e-book and a cooking app. In addition, numerous further training courses will be offered and the results of the project will be made available to other school kitchens throughout Germany.

UN award for the lighthouse project "KEEKS"

In addition to negotiations on the implementation of climate policy goals, lighthouse projects in the area of climate protection were also honored in Katowice in December 2018. As a partner in the "KEEKS - Climate and Energy Efficient School Canteens" project, ifeu is one of the prizewinners in the "Planetary Health" category.

KEEKS received the United Nations Prize together with the project "Aktion Pflanzenpower", which is carried out by ProVeg and BKK ProVita.
