Defining Strategic Environmental Goals and Objectives for the Management of Deep-sea Mining Operations in the Seabed Beyond National Jurisdiction

After the inconclusive second part of the 28th Annual Session of the International Seabed Authority (ISA) in July 2023, there were concerns that the ISA would start accepting exploitation applications for deep-sea mining in the seabed beyond national jurisdiction (the Area) with neither a full regulatory framework in place nor a general policy related to the conservation of our marine environment. Currently, the environmental management of deep-sea mining by the ISA is cursory and lacks strategic aims regarding the preservation of deep-sea ecosystems. This makes the ISA unable to fulfill its environmental stewardship mandate as defined in the United Nations Convention on the Law of the Sea. To overcome this inability, we propose that the ISA defines Strategic Environmental Goals and Objectives by carrying out a Strategic Environmental Assessment of deep-sea mining in the Area, with broader stakeholder engagement and considerations for cumulative and long-term effects. This will allow the ISA to develop the first strategic environmental policy for the Area under its jurisdiction to protect deep-sea ecosystems.
