Geoengineering: Guidance Exists

摘要

In their policy forum "end the deadlock on governance of geoengineering research" (15 March, p. 1278), E. A. Parson and D. W. Keith recognize the environmental and policy risks posed by geoengineering methods and lay out a course of action to address them. They argue that a void in international governance of research exists and that geoengineering operations are subject to no international legal control. They further assess no progress in defining the boundary between small and large activities. In fact, relevant guidance does exist.
