Deep-Sea Mining Race
The race for deep-sea mining targets polymetallic nodules on the ocean floor. These potato-sized rocks contain cobalt, nickel, copper, and manganese. Tech companies and automakers need these metals to build electric vehicle batteries and renewable energy grids. The International Seabed Authority (ISA) controls mining in international waters. The ISA operates under the United Nations Convention on the Law of the Sea (UNCLOS). Countries and mining corporations are currently pressuring the ISA to finalize a mining code. Environmental groups and several nations demand a pause. They argue that mining will destroy unmapped ocean ecosystems and disturb carbon sinks.
Core Context Pillars
Pillar 1
The Clarion-Clipperton Zone in the Pacific Ocean holds the largest known deposits of polymetallic nodules. The ISA issued over 30 exploration contracts to state-backed and private companies in this specific region.
Pillar 2
The island nation of Nauru triggered a two-year rule in 2021. This legal clause forced the ISA to either finalize mining regulations by July 2023 or accept mining applications under draft rules.
Pillar 3
China currently holds the highest number of ISA exploration contracts. The Chinese government manages five separate claim areas and plans to control the future deep-sea supply chain.
Pillar 4
More than 20 countries formally support a moratorium on deep-sea mining. They cite a lack of scientific data regarding the impact of sediment plumes and noise pollution on marine life.
