Summary/Abstract
This article will assess to what extent legal concepts discussed, developed and adopted in the regulatory process under the London Convention and Protocol can provide useful ideas and concepts – and possibly even offer models – for the future regulation of other climate engineering technologies, including ocean fertilization. The article identifies (I) existing and emerging rules under the international law of the sea that govern ocean fertilization and (II) similarities between ocean fertilization and other proposed climate engineering technologies will be identified. Based on this, paradigmatic aspects of the legal concepts and principles developed in the course of the regulation of ocean fertilization under the London Convention and Protocol will be discussed.
