unilateral seabed mining

Seabed mining beyond UNCLOS raises unresolved pollution obligations

A unilateral licence draws a boundary; a sediment plume does not observe it. The United States' move to license nodule recovery in the Clarion-Clipperton Zone outside the International Seabed Authority raises a question sharper than title: which pollution duties bind a nonparty? Customary law answers. Prevention, due diligence, and prior assessment survive exit, while the referent institution's rules thin but never empty. Exit concentrates responsibility. For readers tracing these jurisdictional currents, our coverage of coastal rights and ocean data integrity offers useful depth.
