Coral reef protection to grow with the Green Fins Hub

Sustainable marine tourism is receiving a major boost with the launch of the Green Fins Hub, a global digital platform for diving and snorkelling operators worldwide. The industry-backed digital platform is expected to scale up reach from about 700 operators across 14 countries today to a potential 30,000 worldwide, thus increasing coral protection and conservation worldwide.
The Green Fins Hub is the first-ever global marine tourism industry platform, helping operators to make simple, cost-efficient changes to their daily practices by utilising tried and tested solutions, keep track of their annual improvements and communicate with their communities and customers. The tool has been developed by The Reef-World Foundation in partnership with the UN Environment Programme (UNEP) to overcome the biggest sustainability challenges in the marine conservation tourism industry.
“Coral reefs, home to at least 25 per cent of marine life, are the mecca for marine-related tourism, contributing up to 40 per cent or more of the gross domestic product in some island nations. However, they are a most vulnerable ecosystem, especially to climate change with the difference between a global temperature rise of 1.5 or 2 degrees Celsius being existential for reefs,” said Leticia Carvalho, Principal Coordinator, Marine and Freshwater at UNEP. “Increasing accessibility of best practice, knowledge and citizen science through this global digital hub can be a game changer in ensuring a future for coral reefs and other fragile marine ecosystems.”
The Green Fins Hub is the latest development by The Reef-World Foundation to meet a growing industry demand for environmentally-friendly underwater sports. The foundation recently surveyed over 2,400 dive tourists and professionals, of whom 83 per cent said they are looking for further sustainability education on their holiday, 75 per cent said they would pay more for it, but 85 per cent said that they find it difficult to see if an operator is sustainable.
The Green Fins Hub is intended to catalyse a seismic shift towards sustainability in the marine tourism sector, by hosting two types of Green Fins membership:
Digital membership that will be available to dive, snorkel and liveaboard operations globally. Throughout every year of membership, operators will receive environmental scores based on a detailed online self-evaluation and progress made on their action plans.
Green Fins Certified Members will continue to be assessed annually and trained in person at their operation. The assessment process will continue to be based on set criteria using a scoring system (0-330 point system, with a low score implying low impact of a business on coral reefs). As part of the Green Fins Hub, there will now be a minimum threshold (>200 of a maximum environmental impact score) for becoming a Green Fins Certified Member and a ranking of bronze, silver or gold certified members according to performance.
Additional features on the Hub include:
The Green Fins Community Forum for operators around the world to raise industry needs, discuss environmental issues and share lessons and ideas with like-minded industry leaders, NGOs and governments. For example, dive centres experiencing outbreaks of invasive species like the Crown-of-Thorns Seastar (COTS) at their dive sites can use the forum to gain the resources and expertise to take immediate conservation action.
The Green Fins Solutions Library gives access to over 100 proven environmental solutions to common daily operational challenges, tried and tested by the Green Fins network for over two decades.
The Action Plan: Members will receive an annual sustainability action plan with set goals. An advanced user interface now allows them to track their progress over time.
The Green Fins Hub has been co-created with key industry partners from around the world, to ensure it meets the needs of our stakeholders. Diver training agency, PADI, and its network have pioneered and financially backed this project from its inception. In addition, industry leaders including training agencies PSS, RAID, diver insurance company DAN, dive holiday booking platforms such as ZuBlu and PADI Travel, and a series of Green Fins Members from around the world have helped shape the platform throughout development.
Katie Thompson Global Director of Corporate Social Responsibility at PADI said, “As the world’s leading initiative dedicated to environmental guidelines that promote a sustainable diving and snorkelling industry, we knew that to reduce the global environmental footprint of scuba diving, we had to work closely with Reef-World’s Green Fins initiative. Since the beginning of our partnership in 2018, it’s been a major priority for us to make sure that all 6,600+ PADI Members across the globe have access to the low-cost and practical support that Green Fins membership provides. That’s why we have worked together to conceptualise and refine Green Fins Hub; now every one of our amazing PADI Members can join a community committed to positive change, and work towards a more sustainable future one step at a time.”
The development of the Green Fins Hub has been supported by numerous partners, another indication of the need for such a sustainability tool. Significant support was received from the Inter-American Development Bank through the Beyond Tourism Challenge, UNEP, the Matthew Good Foundation and Conservation X Labs.
“The Green Fins Hub is the solution the scuba diving industry needs to push sustainability efforts forward,” said Adam Broadbent, founder of ZuBlu, a leading dive travel booking platform “By digitalising environmental goal tracking, centralising countless sustainability resources, and encouraging collaboration between operators, the Hub is empowering us all to create a greener future for the big blue we all love.”
“We are very excited about this new development from Green Fins,” says Anais Lefrere, Business Development Manager at DUNE United, an international network of Liveaboards and Dive Centres. “The self-evaluation model on the Green Fins Hub will help us to identify environmental challenges within each of our partner operations and provide step by step support in addressing these. This will ultimately help us to mainstream environmental considerations across our whole brand and help us to demonstrate our commitment to sustainability.“

Make Every Dive Count

The Shark Trust Great Shark Snapshot is back for its 4th year! And this time the Shark Trust are asking you to Make Every Dive Count!
The last week of July will see the return of the Shark Trust’s citizen science initiative: The Great Shark Snapshot. It encourages divers and snorkellers, all around the world, to record the sharks and rays that they see. This year it takes place between the 19th and 27th July. Get ready to dive in!
The event is back for its 4th year, and it is happening in “Shark Month”, more commonly known as July! To coincide with a series of events that celebrate all things shark and ray, including Shark Week and the 50th anniversary of Jaws.
Divers, clubs, centres, charter boats and liveaboards are all encouraged to show their support by organising dives and events throughout the week. As well as gathering vital data, the event will provide a chance to celebrate the incredible shark and ray species that live in our ocean.
Information about the species and numbers of sharks and rays the participants find over the week will be added to the Shark Trust’s Shark Log. This global shark census will, over time, allow shark scientists to build a picture of species distribution and any changes that occur
Caroline Robertson-Brown, Marketing Manager at the Shark Trust said “It is great to see this popular citizen science event back for its 4th year. We are asking divers to Make Every Dive Count this year. To identify. Count and Record every shark, ray and eggcase they see during the week-long event. To organise dives especially to take part. Whether you are diving your local dive site, or on a trip of a lifetime, we want divers to join in on the Great Shark Snapshot in July.”
It is easy to join in. Just go diving between 19th and 27th July and record every shark, ray, skate or eggcase that you and your dive group sees. If possible, take photos and some video footage too. Then make sure that you record your sightings on the Shark Trust Shark Log recordings website or by using the Shark Trust app.
This year we have created a digital guide that puts all the information you need in one handy online guide. Which can be downloaded from the website.
The Great Shark Snapshot is a way for divers to get together, go diving, and do something to help shark conservation. Why not dive in?

The Ocean Cleanup Launches 30 Cities Program to Cut Ocean Plastic Pollution from Rivers by One Third by 2030

The Ocean Cleanup, the international non-profit with the mission to rid the world’s oceans of plastic, has announced, at the UN Ocean Conference (UNOC), its plan to rapidly expand its work to intercept and remove ocean-bound plastic pollution.
The 30 Cities Program will scale the organization’s proven Interceptor™ solutions across 30 key cities in Asia and the Americas, aiming to eliminate up to one third of all plastic flowing from the world’s rivers into the ocean before the end of the decade.
This evolution follows five years of learning through pioneering deployments across 20 of the world’s most polluting rivers and represents a key next step in the organization’s mission and the global fight against ocean plastic pollution.
With the 30 Cities Program, The Ocean Cleanup will transition from single river deployments to citywide solutions, tackling the main plastic emitting waterways within each selected city. This follows a key learning from deployments in Kingston, Jamaica, which showed it is possible to scale faster when projects encompass whole cities, as the same set of partners can be involved with all deployments.
To date, The Ocean Cleanup has already prevented 29 million kilograms of trash from reaching the ocean. The organization currently intercepts an estimated 1–3 percent of global river-borne plastic emissions. With the first 20 river deployments close to being fully operational, it is now poised to reduce the plastic pollution flowing into the ocean from rivers by up to a third.
“When we take on an entire city, instead of individual rivers, we can scale faster, reduce costs, and maximize impact,” said Boyan Slat, Founder and CEO of The Ocean Cleanup. “Our analysis shows that strategically deploying Interceptors across just 30 carefully chosen cities can stop up to a third of river plastic pollution worldwide. This is the next big leap toward our ultimate goal of a 90 percent reduction in global ocean plastic pollution.”
City-by-city: a Faster Path to Scaling
Using the latest scientific modeling and on the ground experience, The Ocean Cleanup identified 30 major plastic polluting coastal cities which include:
• Panama City, Panama – First deployment to go live in the coming months.
• Mumbai, India – Mapping of all waterways completed; preparations for first deployments underway.
Furthermore, the organization is developing plans to expand on its existing work to all polluting rivers in:
• Manila, Philippines; Montego Bay, Jamaica; Jakarta, Indonesia; Kuala Lumpur, Malaysia; Bangkok, Thailand and Los Angeles, U.S.A.
Other cities will be announced once the necessary partnerships and agreements are in place. Planning and fundraising activities are underway for all 30 cities. To realize these ambitious plans, the organization is currently also expanding its engineering and operational capacity.
Data Driven Restoration at Scale
Before Interceptors are deployed, each city project begins with an intensive analysis phase. Aerial drones, AI-powered image analysis, and GPS-tagged “dummy” plastics are used to chart every visible waterway and track how waste moves from streets to sea. These real-time insights guide optimal Interceptor placement and provide a public baseline against which progress can be measured.
Alongside intercepting new plastic, the 30 Cities Program will also remove debris from nearby coasts, mangroves, and coral reefs. This twin-track approach—shutting off the tap while clearing the legacy pollution—enables The Ocean Cleanup to achieve long-term impact, which includes the restoration of fish nursery habitats, boosting coastal tourism, and strengthening of natural storm surge defenses for local communities. Alongside local partners, the organization also advocates for improvements in waste management and awareness raising amongst communities.
Completing the First 20 Rivers
While laying the foundation for the 30 Cities Program, The Ocean Cleanup is also nearing completion of its first 20 river projects. The next landmark achievement—expected as soon as the second half of this year—is in the western Caribbean, where the team aims to resolve the plastic pollution problem in the Gulf of Honduras by intercepting the trash feeding into this body of water.
A Stepping Stone Toward a 90 Percent Reduction
The 30 Cities Program represents the first major scaling step in The Ocean Cleanup’s journey to eliminate 90 percent of floating ocean plastic pollution. In parallel, efforts are continuing to remove plastic from the Great Pacific Garbage Patch. Whilst extraction operations are currently on hiatus, work to deploy cutting edge technologies to map the “hotspots”, or areas of intense plastic accumulation, in order to make future extractions more efficient and economical, is ongoing.
By combining river interception and coastal cleanup with its offshore cleanup systems targeting legacy pollution that’s already in the ocean, the organization is charting a path to turn off the tap and mop up the mess.
About The Ocean Cleanup
The Ocean Cleanup is a nonprofit organization that develops and scales technologies to rid the oceans of plastic. By conducting extensive research, engineering scalable solutions, and partnering with governments, industry, and like-minded organizations, The Ocean Cleanup is working to stop plastic inflow via rivers and remove legacy plastic already polluting the oceans. As of June 2025, the non-profit has collected over 28 million kilograms (62 million pounds) of trash from aquatic ecosystems around the world. Founded in 2013 by Boyan Slat, The Ocean Cleanup now employs a multi-disciplined team of approximately 200 people. The organization is headquartered in Rotterdam, the Netherlands, with international operations in 10 countries. For more information, visit www.theoceancleanup.com.
