Ocean Governance

The ocean holds some of the world’s largest reservoirs of biodiversity, and by storing vast amounts of carbon, it helps keep our planet–and people–healthy.

The ocean is also a vital source of food for billions of people and supports livelihoods in communities worldwide.

However, the health of the ocean is in decline. Technological advancements have made nearly every inch of the world’s marine waters increasingly accessible and vulnerable to extractive activities, including large-scale fishing, energy development and deep-sea mining. Habitat destruction caused by human activities is further compounded by the impacts of a changing climate.

These cumulative threats cannot be tackled by any nation nor any sector alone, and gaps in global ocean governance can be addressed effectively only through international cooperation. Since the ocean is an interconnected natural system governed by a patchwork of domestic and international policies and bodies, countries must work together to manage and safeguard the marine environment.

The Pew Charitable Trusts is working closely with governments, key stakeholders and partner organizations to develop policies – and policy mechanisms – to minimize harm to the ocean while ensuring that it continues to provide for humankind.

The ocean governance project combines Pew’s efforts to:

  1. Implement and improve the World Trade Organization’s fisheries subsidies agreement.
  2. Secure and advance the United Nations high seas treaty.
  3. Secure and further execute the Convention on Biological Diversity’s target to protect 30% of global land and marine areas by 2030. 
  4. Engage with the International Seabed Authority to ensure that deep-sea mining is prohibited unless effective protection of the marine environment can be assured.

Why Deep-Seabed Mining Needs a Moratorium

The ocean is crucial for keeping the planet healthy, yet it’s under strain from damaging activities and climate change.

Fisheries Subsidies Agreement: Why It Matters

On 15 September 2025, a World Trade Organization (WTO) agreement to help end harmful fisheries subsidies entered into force, giving governments around the world a significant new tool in the effort to stem overfishing and illegal fishing. The historic agreement, which the WTO adopted in June 2022, will tackle one of the key drivers of overfishing by curtailing harmful subsidies – payments made by nations to commercial fishing operators to keep those businesses profitable.

WTO Fisheries Subsidies Deal Now Needs Implementation

With a World Trade Organization (WTO) agreement to curb harmful fisheries subsidies newly in place, it’s finally time for governments to implement this critical deal.

Inside the New High Seas Treaty

On 20 September 2023, the United Nations opened its new agreement on the conservation and sustainable use of marine biodiversity beyond national jurisdiction—also known as the BBNJ treaty or high seas treaty —for signature and ratification.
