Governance Challenges of Deep Seabed Mining

The UN Convention on the Law of the Sea designated the deep seabed as the “common heritage of mankind” and created the International Seabed Authority (ISA) to oversee mining rights, ensure equitable benefit-sharing, and protect the marine environment.

Frustrated by regulatory delays and scientific uncertainty, corporate actors are exploiting jurisdictional gaps and partnering with non-signatory states to bypass the ISA and pursue mining outside the UNCLOS framework.

Operational progress is hindered by unresolved financial mechanisms for royalty distribution and significant environmental concerns, particularly regarding biodiversity loss and the difficulty of monitoring remote deep-sea ecosystems.

While some investors support circumvention strategies, mining outside the UNCLOS system creates substantial legal risks and threatens the legitimacy of the global governance regime intended to prevent unilateral exploitation.
