We believe
in healthy seas
for all.

Common Seas is on a mission to quickly and significantly reduce the amount of plastic produced and stop it polluting our rivers and seas.

We fund our work through philanthropic investment and consultancy work for governments and brands. We also reinvest any returns from our investment into circular economy solutions.

Our Approach

  1. We need government policy that propels a change in how we make, use and dispose of the plastic that ends up in our ocean

    Shifting Cultural Norms

  2. We need a cultural shift that generates support for plastic alternatives, bolsters new markets and accelerates the adoption of a plastic waste-free economy.

    Investing in the circular economy

  3. We need self-sustaining circular solutions that remove problem plastics from our economy and prevent plastic from becoming waste.

Why plastic?

Plastic kills and harms many millions of sea creatures. But it’s not just marine life: humans are more exposed to plastic than any other species, and there’s strong evidence this affects our health. A polluted ocean also harms our economy, our global food supply and our climate.

Despite this, if the petrochemical industry has its way we’ll be making twice as much plastic by 2040. If they can’t sell their oil and gas as energy, they’ll sell it as plastic.

Meanwhile, 11 of the world’s 20 most plastic-polluting countries lack a robust reduction strategy. And fulfilling every existing commitment on plastic will only reduce pollution by 8% in the next 20 years.

We're hands on

Common Seas is an international team of scientists, researchers, policy experts, communicators and behaviour change professionals. Together, we test our ideas in the field, learn from our own and others’ mistakes and all share a deep love of the sea.

See our hands on approach in Paros, Greece

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 collaborative

Plastic pollution is too big and too complex a problem to solve alone. Our work harnesses the collective experience of community, academic, government and business experts. Together, we solve problems and make things happen - in the community, across a country and around the world.

Our Story

Our mission and approach have been shaped by two forces. First, our founders’ lifelong professional and spiritual connection to the ocean. And second, over a decade of ground-breaking work safeguarding resilient and productive seas.
