Common Seas.
Healthy Seas for Everyone.

We need the Ocean. We love the seas. But because they’re in trouble, we are too.

Common Seas exists to find, test and facilitate solutions to our global plastic pollution crisis. By working together, we can make the big changes we need to protect the greatest life support system on Earth.

In practice, that means our work tackles plastic waste at its source, delivers new ways to manage and re-use plastic, and stops the leakage into our rivers, seas and ocean.

Our Mission

To quickly and significantly reduce the amount of plastic waste produced and stop it polluting our Ocean.

Common Seas Health Workshop

We are collaborative.

Plastic pollution is too big and too complex a problem to solve alone. Common Seas provides the right people with the right tools to navigate this complexity and connect with the right partners to make change happen.

We are catalysts

Our research and work on-the-ground harnesses the collective expertise of people, governments and businesses. Through a participatory co-design approach, we build capacity, infrastructure and momentum to catalyse change at a community, national and international level.

We are hands-on

Common Seas brings together an international team of scientists, policy experts and behaviour change professionals. Through our project work, we connect at a personal and practical level with people making change on the ground. We test our ideas in the field, learn from our own and others’ mistakes and are driven by a shared love of the sea.

We currently do this through four projects:

Plastic Drawdown

This new approach to addressing plastic pollution helps governments understand plastic waste flows and optimise policies to effectively ‘drawdown’ the flow of ocean plastic pollution.

Clean Blue Alliance

Our vision is a global network of plastic waste-free islands. We are working with governments, councils, businesses and local changemakers to identify and accelerate solutions.

Ocean Plastics Academy

Common Seas wants to inspire a generation of sea champions, and we are working with schools to put plastic pollution and the ocean into the school curriculum.

Healthy Me. Healthy Sea.

Plastic is part of everyone’s daily lives, but how is this affecting our health? We are researching the health impacts of eating, drinking and breathing plastic.

History

Our mission and approach have been shaped by two forces. First, our founder Jo Royle’s previous career at sea skippering expeditions and trans-ocean yacht races, including voyages across the Atlantic and Pacific, and down to the Antarctic. And second, a decade of ground-breaking work safeguarding resilient and productive seas.
