The National Environmental Research Institute (NERI) of Denmark was a self-regulating research institute under the Aarhus University. NERI undertook scientific consultancy work and monitoring of nature and the environment as well as applied and strategic research. NERI’s primary task was to create a scientific foundation for environmental policy decisions. NERI participated in a large number of national and international research programmes, and also in scientific working groups, commissions, and organizations under such bodies as the European Union and the United Nations. In 2011, NERI closed. The consultancy side was reorganised into The DCE - Danish Centre for Environment and Energy, while the research departments of the old NERI are now divided between the Department of Bioscience and the Department of Environmental Science.
