The employment of sustainable business practices is an essential part of the social responsibility of an internationally active organization. Fraunhofer also accepts this responsibility and is committed to international sustainability goals, whether as a contribution to the UN Sustainable Development Goals, the Paris Climate Agreement or the ten recognized sustainability principles of the UN Global Compact. Since 2017, Fraunhofer has been a member of this international network and has since supported the principles for ethical business practices, in particular with respect for human rights. As part of its corporate social responsibility activities, the Fraunhofer-Gesellschaft has developed sustainability standards for its suppliers, vendors, service providers and other potential business partners. These standards essentially address business dealings with stakeholders along the entire value chain. Particular focus is placed on suppliers, and their partners, who are directly involved in the provision of services for the Fraunhofer-Gesellschaft. In doing so, these partners commit not only to upholding laws and regulations but also to respecting human and labor rights. An additional aspect addressed is environmental and climate protection. Here, too, the Fraunhofer-Gesellschaft requires that its potential business partners adhere to strict guidelines in order to avoid behavior that is harmful to the environment and to promote sustainable business practices. The sustainability standards also include control mechanisms as well as any remedial measures.
