On 4 May 2026, Prof. Dr J.B. Opschoor passed away at the age of 81. From 1982 to 1990, he was director of the Institute for Environmental Studies (IVM).
After studying economics in Rotterdam and spending time in Botswana, Hans Opschoor was one of the founders of the IVM at VU University Amsterdam in 1971. At the time, the institute consisted of a small group of young, enthusiastic academics who were convinced that tackling environmental problems would benefit from applied interdisciplinary research. In the early years, Hans focused primarily on the damage caused by environmental pollution and the possibility of quantifying its economic impact. That subject formed the basis of the thesis on which he obtained his PhD in 1974.
After his appointment as director of IVM in 1982, he remained active as a researcher. In 1987, he was appointed professor. In his inaugural lecture, ‘Sustainability and Change’, he introduced the concept of ‘environmental space’, a term that remained popular among researchers and policymakers for a long time. In addition, Hans was the first editor-in-chief of Environmental & Resource Economics, the European journal of environmental economics that is still regarded as a leading publication in the field.
Hans always paid particular attention to the international dimensions of environmental issues, as well as to the relationship between the environment and development. He initiated various projects and partnerships in Africa, Asia and Eastern Europe.
After leaving IVM in 1990, Hans served, among other roles, as professor of environmental economics at the Faculty of Economics at VU University Amsterdam, chair of the Council for Environmental and Natural Research (RMNO), and rector of the Institute of Social Studies in The Hague.
Hans believed strongly in working together to create a better world. His presence rarely went unnoticed – not only because of his ideas but also because of his booming voice and roaring laugh. At the same time, he was a good listener and showed genuine interest in others. For many who worked with him or knew him, he remains a memory of an inspiring colleague and a remarkable person. He will be missed.
