R. 3748 IN THE HOUSE OF REPRESENTATIVES June 5, 2025 Mr. Bera (for himself, Mr. Moylan , Mr. Case , Mrs. Radewagen , and Mr. Krishnamoorthi ) introduced the following bill; which was referred to the Committee on Foreign Affairs A BILL To require the Secretary of State to submit to Congress a report on the promotion of certain policies regarding the effects of sea level rise on the statehood and maritime zones of countries, and for other purposes.

1. Short title This Act may be cited as the Maintaining Area Rights and Integrity Through International Maritime Enforcement Act or the MARITIME Act . 2. Findings Congress finds the following: (1) Increasing sea levels pose an existential threat to low-lying island States in the Pacific Ocean. (2) Maritime zones are critical for the economies of the Pacific Islands, which depend on exclusive rights to resources. (3) New trends are developing in the practices and views of States on the need for stable maritime zones in the face of sea level rise, as reflected in the approach taken by the members of the Pacific Islands Forum and the Alliance of Small Island States. 3. Statement of policy It is the policy of the United States that— (1) sea level rise driven by climate change should not cause any country to lose its statehood or its membership in the United Nations, its specialized agencies, or other international organizations; (2) the United States is committed to working with other countries on issues relating to sea level rise and statehood to advance these objectives; (3) sea level rise driven by climate change should not diminish the maritime zones on which island States and other coastal States rely, including for food and livelihoods; (4) the United States is committed to preserving the legitimacy of maritime zones, and associated rights and entitlements, that have been established consistent with international law as reflected in the United Nations Convention on the Law of the Sea and that are not subsequently updated despite sea level rise caused by climate change; (5) countries should support the initiative of the Pacific Islands Forum and the Alliance of Small Island States to take steps now to determine, memorialize, and publish their coastal baselines in accordance with the international law of the sea as set out in the United Nations Convention on the Law of the Sea; and (6) the United States will encourage countries to adopt similar policies on the issue of statehood and the preservation of maritime zones. 4. Report (a) In general Not later than 120 days after the date of the enactment of this Act, the Secretary of State, in consultation with the heads of other relevant Federal agencies, shall submit to the appropriate congressional committees a report on the efforts of the United States to promote the adoption, by foreign countries and international organizations, of policies that are complementary to United States policies regarding the effects of sea level rise on the statehood and maritime zones of countries.
