Professor Sir Partha Dasgupta is a pioneer in the field of environmental economics: making the economic case for biodiversity. He is Emeritus Professor of Economics at the University of Cambridge and and Chair of the Management Board of its Centre for the Study of Existential Risk. Last year he was appointed by the Chancellor of the Exchequer to lead an independent global review to assess the economic benefits of biodiversity and the economic costs of its loss.
