The international community has been trying to regulate ocean fertilization technology as a new geoengineering technique to deal with climate change for about a decade. During this period, some strategies have been proposed by international jurist to govern this technology in the international law Regime. These solutions have been mainly driven from the available treaties such as Convention on the Law of the Sea, the Framework Convention on Climate Change, the Convention on Biological Diversity, and the London Convention Dumping Regime. There is no doubt that treaties are considered one of the primary and traditional sources of international law, as well as a means of creating rights and obligations for subjects of international law. Treaties are widely recognized as one of the most suitable forms for lawmaking and regulation in the framework of international law. Due to their efficient and expeditious approach to law-making, the significance of their role in shaping new rules of International Law continues to grow steadily. Despite the continuous and rapid advances in science and technology, contemporary international law faces new challenges in various fields, one of which is related to regulating new technologies such as ocean fertilization. The most important question in this issue is whether the capacity of existing treaties can be utilized for regulating ocean fertilization technology. The authors of the article hypothesize that although it is better to have scattered rules than none at all, treaties that have directly or indirectly addressed this technology have their weaknesses and gaps due to issues such as ignoring the benefits of fertilization as one of the emerging technologies to deal with climate change, ambiguities existing in defining the critical concepts related to this technology, content inconsistency, and neglecting the position of private actors. Therefore, these treaties do not fully represent the current situation, and the result will be incomplete regulation. Hence, in the present study, it is shown that International community needs to regulate ocean fertilization technology with a dedicated document, but until then, soft law capacities can be utilized for its regulation. Soft law tools are beneficial, especially when solutions are unclear, and their voluntary nature encourages participation by governments and non-state actors.
