The focal point of the international law framework for the protection of the marineenvironment is Part XII of the 1982 United Nations Convention on the Law ofthe Sea (LOSC)1 on the Protection and Preservation of the Marine Environment,complemented by a burgeoning variety of instruments on internationalenvironmental law and an evolving body of customary international law principles.Substantial implementation of this framework has occurred in marine areas withinnational jurisdiction with some transboundary collaboration between States indifferent regions to protect their marine environment across national boundaries.The regulatory framework for environmental protection in marine areas beyondnational jurisdiction (ABNJ) is at a much earlier stage of development as Statesgrapple with the broader institutional and legal challenges posed by high seasgovernance.
