Abstract
This article traces international conflicts over the making and operation of the first global environmental information system, Infoterra (1972–2003). By studying the negotiations among international actors over what kinds of information, expertise, and technological infrastructure were deemed appropriate to constitute Infoterra, we gain insight into what was made to count as environmental information, and how “the environment” was communicated to multiple audiences in the early decades of the global environmental movement. The article argues that the struggles around Infoterra demonstrate the key role attributed to information systems for global environmental communication, with lasting impacts on pragmatic responses to environmental problems today.
