Summary/Abstract
This article from the International Environmental Law Committee newsletter provides an overview of the legal posture of ocean iron fertilization (OIF) activities under international environmental law. The paper reviews the LOHAFEX ocean iron fertilization research mission in this context. The LOHAFEX case presents an interesting example of how authorities are often required to apply, and in some cases reconcile conflicts between, distinct legal and policy frameworks that arise under separate treaties. In addition, the OIF regulatory developments themselves merit more general attention as a potential model for the international community in evaluating how to regulate other forms of “geoengineering” to mitigate climate change.
