About Us

The High Seas Alliance is a partnership of organizations and groups aimed at building a strong common voice and constituency for the conservation of the high seas. The Alliance is currently made up of 50+ NGOs plus the International Union for the Conservation of Nature (IUCN).

The objective of the Alliance is to facilitate international cooperation to establish high seas protected areas and to strengthen high seas governance. Members of the HSA share and facilitate access to information in order to promote transparency and encourage an informed public discourse related to the mission and goals of the Alliance.

High Seas Alliance members commit to working together to achieve these goals either as members of a collaborative effort through the Alliance, or as individual organizations supported by or affiliated with the Alliance.

Our Mission

Our mission is to conserve the world’s high seas — which cover half of our planet.


  • To build a strong common voice and constituency for high seas conservation.
  • To promote and catalyse the protection, conservation and restoration of marine ecosystems and biodiversity.
  • To promote and catalyse the building of a comprehensive, representative and effective system of marine protected areas (MPAs), including no-take reserves.
  • To catalyse and monitor the effective implementation of existing and emerging ocean conservation obligations and rules.
  • To promote and monitor effective governance, management and enforcement systems that support and ensure conservation, sustainability of use and equitable benefit sharing for all high seas marine resources and species, including fisheries.

HSA members are committed to working together to inspire, inform and engage the public, decision makers and experts in support of high seas conservation, and to working through relevant intergovernmental processes and organizations to ensure that meaningful action is taken to achieve these common goals.
