M.Sc. in horticulture in 1984 from the Royal Agricultural University of Copenhagen. In 1993 he obtained the Ph.D. degree from the Technical University of Denmark on a thesis on life cycle assessment. Since then he has been working as a consultant on life cycle assessment. Executive manager of the ecoinvent database from 2008 to 2012 and its Chief Scientist from 2012 to 2014. He is professor at Aalborg University and expert delegate to the ISO TC 207 / SC5 on life cycle assessment as well as president of the International Life Cycle Academy (ILCA).
