Our work in focus

Sewage pollution

We campaign for a clean ocean, rivers and lakes for wildlife and people. It's time to #EndSewagePollution, once and for all.

Plastic pollution

We campaign to turn back the plastic tide choking the ocean. We are The People vs Plastic.

Data HQ

We lift the lid on the state of UK water quality, empowering campaigners to take on the polluters.

Regional Reps

Our Regional Reps community powers the fight for the ocean across the length and breadth of the UK.

Check for sewage and pollution alerts

Our free Safer Seas & Rivers Service allows you to check for sewage pollution alerts in real-time. And through the app you can also take campaign action to hold the polluters to account. Download now.

Take part in the Million Mile Clean

We raise awareness of plastic pollution through mobilising hundreds of thousands of Ocean Activists, UK-wide, to clean their local environment. And the data we gather supports our campaigns against the polluters.
