Outer Space as a Global Commons: An Empirical Study of Space Arrangements

The designation of outer space as a global commons is a contentious issue. Some argue that officially recognizing it as such could discourage private investment, while others claim that it would not sufficiently promote sustainability. To address these debates, this article examines how space actors use a global commons framework in their institutional arrangements. Based on a collection of 1042 space arrangements, we characterize a subset of arrangements that explicitly reference concepts related to the notion of global commons. We observe that this framework is seldom used in bilateral arrangements and is mostly absent from recent agreements made by influential players. Furthermore, we find that employing principles related to global commons in arrangements does not result in significantly different operational rules. As a result, we conclude that a clearly defined global commons perspective has yet to be articulated and institutionalized.
