Sustainability implementation affects all parts of an institution. Research institutes typically have high energy demands and traffic / mobility emissions, but buildings, paper, office supply, waste, the canteen and other segments are also of great importance. Energy savings and reduction of mobility emissions surely are key factors and need custom-tailored solutions. However, sustainability means more than reducing direct emissions. To reach all parts of an institution, high level decisions are needed to cover all parts of the institution, and a management and reporting scheme, best case with external auditing, is necessary to ensure long-term progress and sustained efforts to reach sustainability goals. Last but not least dedicated staff is needed to introduce sustainability guidelines and support.
