World Ocean Week

2 minute read

We've got a week-long celebration planned to honour World Ocean Day. Get involved in clean-ups, creative campaigns and community events, all leading up to the UK’s game-changing Deposit Return Schemes in 2027.

Act for the ocean

Join us in celebrating World Ocean Day 2026 by taking part in one of our events - or organising your own - between the 16th and 12th of June. Learn more about pro-ocean actions you can take, get creative, and connect with others to make an even bigger splash.

With the UK’s Deposit Return Schemes launching in 2027, we’ll be focussing on how we can support the schemes, evidence the urgent need for their introduction and ensure they’re delivered on time.

There will also be opportunities to get creative, and connect and learn through workshops, training sessions and Q&As.

Find out what’s on offer below or organise your own World Ocean Week event!

Clean up

Whether you're living inland or by the sea, you can help collect vital litter data throughout the week. Our team of experts will analyse the data you collect, and you’ll be contributing towards a UK-wide picture of the litter found in our communities.

We’ll examine hotspots for bottles, cans or other drinks-related rubbish and use this to highlight the importance of Deposit Return Schemes. 

Run a Source to Sea Litter Survey in your community

Create

If getting crafty is more your style, design a poster for your local area raising awareness of the upcoming Deposit Return Scheme in 2027 and encouraging your community to use it.

Report a jellyfish sighting

Whether you live by the coast or visit the seaside this World Ocean Week, we want you to tell us every time you spot a jellyfish. Or, if you're lucky enough to spot a turtle, we want to hear about that too.

There are eight different jellyfish, or jellyfish-like, species and six marine turtles that you might see in our waters.

It’s really easy to tell us what you have seen, just fill in the online sightings form including where you were and what species you saw. Don’t worry, we’ve made some useful ID guides so you can identify which species you’ve spotted!

What is a Deposit Return Scheme?

A Deposit Return Scheme is a system where you pay a small deposit on top of the price of a drink. When finished, you return the drinks container to a collection point – like a supermarket or shop – and get the deposit back. 

It’s a simple but effective system that reduces littering, puts value on what’s commonly seen as ‘worthless’, and encourages people to pick up drinks litter that they find. 

All UK nations have committed to implementing a Deposit Return Scheme (DRS) for plastic bottles and cans, with Wales also including glass, by October 2027. These schemes have already been delayed, so we need to keep up the pressure to make sure DRS becomes a reality.
