Summary/Abstract
This article focuses on ocean fertilisation and its transboundary impacts. It is divided into the following parts: Part I explains the attractiveness of geoengineering as a mitigation mechanism, Part II discusses geoengineering in the context of climate disaster law, Part III explores the implications of geoengineering deployment by States and existing international customs and treaties, Part IV explores the implications of geoengineering deployment by private companies and existing regulations and Part V considers how international law should be reformed to manage the risks of geoengineering. However, due to the huge international cooperation required and the international community’s fragmented approach to managing climate change and disasters, the article concludes that the risks of geoengineering can probably never be effectively regulated.
