The mission of the U.S. Department of State is to lead America’s foreign policy through diplomacy, advocacy, and assistance by advancing the interests of the American people, their safety, and economic prosperity. Among critical environmental issues, the Bureau of Oceans and International Environmental and Scientific Affairs (OES) leads and coordinates interagency efforts to address the global crisis of marine debris. OES works to reduce marine debris through international bilateral and multilateral engagements, such as leading the U.S. delegation to UNEP, APEC, and other multilateral organizations and by advocating for innovative solutions to address marine debris at its sources. OES also supports private-public collaboration, mobilizes millions of dollars to assist capacity building, including to promote environmentally sound waste management and spearheads programmatic efforts focused on supporting scientific research and promoting education and outreach.
