Oceans

Healthy oceans that benefit the planet, people, prosperity, and peace

Why oceans matter

The ocean is critical to sustaining life on the planet. It produces 50% of the world’s oxygen and regulates the climate by absorbing excess heat and 30% of CO2 emissions. Over 3 billion people rely on seafood for their primary source of protein and livelihoods. The ocean economy is worth $24 trillion dollars and supports hundreds of millions of jobs.

Our approach to oceans

At WWF, we take an integrated approach to ocean conservation. We protect and restore the seascapes that matter the most across the globe. We make blue food systems more sustainable and resilient. And we engage markets and deploy capital towards a nature-positive ocean economy.

Seascapes

We protect the places that matter most across the globe through our work in the US Arctic, Eastern Pacific, Southwest Indian Ocean, and Southwest Pacific and Indonesia. We tailor solutions across nature-based solutions, community-based conservation, and other interventions like finance, policy, and private sector engagement to meet the unique needs of the seascapes where we work.

Blue foods

We make blue food systems more resilient. Our work in fisheries and aquaculture advances livelihoods, food security, and marine ecosystem health. Our work with seafood markets engages global seafood buyers and their supply chains in responsible, sustainable sourcing. Our peace and security work promotes collaborative management, inclusive solutions, and durable conservation to protect nature.

Ocean markets and finance

We engage markets to transform business-as-usual and deploy capital towards a nature-positive ocean economy through our work with the private sector across seafood, shipping, marine renewable energy, coastal and marine tourism, and finance. Our work is grounded in nature positive science and supported by blended and innovative finance to enable sustainable ocean conservation.
