4 3 “IZS – one campus – countless ideas” Following the first Sustainability Action Day in the previous year, the Sustainability Action Week in June 2013 offered the opportunity for scientific exchange as well as for information and discussion on all aspects of sustainability. All the scientific staff at the Stuttgart Institute Center (IZS) were invited to take part in a research “bourse” or “exchange”, which constituted the prelude to a campus-wide project competition. The partic- ipants had the opportunity to present project ideas, discover synergies and find cooperation partners. The ideas presented ranged from a smartphone app for conservation-conscious angling to a location concept for a science and discovery cen- ter for young researchers. Besides regional dishes in the “piccante” company cafeteria, the Action Week offered presentations on sustainability man- agement at the Fraunhofer-Gesellschaft as well as on integrat- ing phone- and video-conferencing into one’s everyday work, which were followed with interest by the listeners. The pre- sentations formed part of the Sustainability Working Group’s ongoing information drive consisting of leaflets distributed center-wide and events intended to encourage all employees to act in a resource-conscious manner. SUSTAINABLE DEVELOPMENT IN DIALOG 1 1 While in 2013 we could look back at five years of the Fraunhofer Sustainability Network and 300 years of “Sylvicultura oeconomica” by Hans Carl von Carlowitz, the founder of the idea of sustainability, the focus at the Fraunhofer IGB is firmly on the future and how we can make it sustainable. Last year’s activities of the cross-institutional Sustainability Working Group (based at the Fraunhofer Campus in Stuttgart) were concerned with cross-linking research into sustainability; the Fraunhofer IGB also contributed ideas for responsible development of the Fraunhofer Institutes within the framework of the “Sustainability Report- ing Guidelines” project, which will make a wide-ranging platform of experience and knowledge on the subject available to all Fraunhofer Institutes. The research exchange workshop was followed by a competi- tion, lasting until the fall, for funding of 30,000 euros made available by the five Stuttgart-based Fraunhofer Institutes. Project teams drawn from at least two institutes elaborated ideas for sustainable development projects and presented these at the second workshop. In the end, the jury made up of institute directors and representatives of the Sustainability Working Group selected three projects to receive initial fund- ing, two with Fraunhofer IGB participation: “Software tool for building responsibles for the environ- mental and economically optimized renovation of built-up urban districts” (IAO, IBP), “Substantial recycling of carbon dioxide in algae produc- tion” (IBP, IGB), “Development of a concept for a center for future issues, including an academy for sustainability technologies, in the metropolitan region of Stuttgart” (all five institutes).
