This article examines the emergence of global environmental perceptions and policies in the preparatory phase of the UN Conference on the Human Environment 1968–1972, based on an internationally comparative study of sixty-three preparatory country reports. Located at the intersection of global, knowledge, environmental and political history, the article raises two theses. First, that ‘the environment’ emerged as a field of knowledge in not only capitalist industrial societies but globally, thus in socialist and non-industrial societies too. Second, the article demonstrates a large overlap of environmental policies taken across geographical and ideological lines. Thus, the article sheds light on the understanding of environmental problems as well as national and international environmental policy measures around 1970 and thereby contributes to the question of how environmental governance emerged as a global field.
