Plastic waste causes $13 billion in damage to marine ecosystems every year, says UN agency
Concern is growing over widespread plastic waste that is threatening marine life – with conservative yearly estimates of $13 billion in financial damage to marine ecosystems, according to two reports issued at the inaugural meeting of the United Nations Environment Assembly.
“Plastic contamination threatens marine life, tourism, fisheries and businesses,” underscores the eleventh edition of the UN Environment Programme (UNEP) Year Book, which updates 10 issues previously highlighted over the past decade and provides mitigation steps for each.
“Plastics undoubtedly play a crucial role in modern life, but the environmental impacts of the way we use them cannot be ignored,” added Achim Steiner, UNEP Executive Director.
Valuing Plastic, a UNEP-supported report produced by the Plastic Disclosure Project (PDP) and Trucost, makes the business case for managing and disclosing plastic use in the consumer goods industry.
“Over 30 per cent of the natural capital costs are due to greenhouse gas emissions from raw material extraction and processing,” says the report, adding “marine pollution is the largest downstream cost, with the $13 billion figure most likely a significant underestimate.”
Calculating the negative financial impact of issues, such as marine environment or air pollution caused by incinerating plastic, the report reveals that the overall natural capital cost in the consumer goods sector each year is $75 billion.
A large and unquantifiable amount of plastic waste enters the ocean from littering, poorly managed landfills, tourist activities and fisheries. Some of this material sinks to the ocean floor, while some floats and can travel over great distances on ocean currents – polluting shorelines and accumulating in massive mid-ocean gyres.
“These reports show that reducing, recycling and redesigning products that use plastics can bring multiple green economy benefits: from reducing economic damage to marine ecosystems and the tourism and fisheries industries – vital for many developing countries – to bringing savings and opportunities for innovation to companies while reducing reputational risks,” advocated Mr. Steiner.
There have been many reliable reports of environmental damage due to plastic waste that include mortality or illness when ingested by sea creatures such as turtles; entanglement of animals, such as dolphins and whales; and damage to critical habitats, such as coral reefs.
There are also concerns about chemical contamination, invasive species spread by plastic fragments and economic damage to the fishing and tourism industries in many countries by, for example, fouling fishing equipment and polluting beaches.
Since the 2011 UNEP Year Book last reviewed plastic waste in the ocean, concern has grown over microplastics (particles up to 5 mm in diameter, either manufactured or created when plastic fragments), which have been ingested by marine organisms – including seabirds, fish, mussels, worms and zooplankton.
“One emerging issue is the increasing use of microplastics directly in consumer products, such as ‘microbeads’ in toothpaste, gels and facial cleansers,” explains the UNEP Year Book. “These microplastics tend not to be filtered out during sewage treatment, but are released directly into rivers, lakes and the ocean.”
Communities of microbes have been discovered thriving on microplastics at multiple locations in the North Atlantic – where the “plastisphere” can facilitate the transport of harmful microbes, pathogens and algal species.
The Yearbook affirms that “microplastics have also been identified as a threat to larger organisms, such as the endangered northern right whale, which is potentially exposed to ingestion through filter-feeding.”
Production trends, use patterns and changing demographics are expected to cause increasing plastic use, and both reports call for companies, institutions and consumers to reduce their waste.
Valuing Plastic finds that while consumer goods companies currently save $4 billion each year through good plastic management, such as recycling, plastic use disclosure is poor. Less than half of the 100 companies assessed reported any data relevant to plastic.
“The research unveils the need for companies to consider their plastic footprint, just as they do for carbon, water and forestry,” said Andrew Russell, Director of the PDP. “By measuring, managing and reporting plastic use and disposal through the PDP, companies can mitigate the risks, maximize the opportunities, and become more successful and sustainable.”
Initiatives such as the PDP and UNEP-led Global Partnership on Marine Litter have helped raise awareness of, and begun to address, the issue. However, much more needs to be done.
Recommendations of the reports include that companies monitor their plastic use and publish the results in annual reports; and commit to reducing the environmental impact of plastic through clear targets, deadlines and efficiency and recycling innovations.
Since plastic particles can be ingested by marine organisms and potentially accumulate and deliver toxins through the food web, efforts should be stepped up to fill the knowledge gaps and better understand the capacity of various plastics to absorb and transfer persistent, toxic and bioaccumulating chemicals.
“By putting a financial value on impacts – such as plastic waste – companies can further integrate effective environmental management into mainstream businesses,” asserted Trucost Chief Executive Richard Mattison. “By highlighting the savings from reuse and recycling, it builds a business case for proactive sustainability improvements.”

Leading UK-based shark conservation charity, the Shark Trust, is delighted to announce tour operator Diverse Travel as a Corporate Patron
Corporate Patrons provide a valuable boost to the work of The Shark Trust. The Trust team works globally to safeguard the future of sharks, and their close cousins, the skates and rays, engaging with a global network of scientists, policymakers, conservation professionals, businesses and supporters to further shark conservation.
Specialist tour operator Diverse Travel has operated since 2014 and is committed to offering its guests high quality, sustainable scuba diving holidays worldwide. Working together with the Shark Trust will enable both organisations to widen engagement and encourage divers and snorkellers to actively get involved in shark conservation.
“Sharks are truly at the heart of every diver and at Diverse Travel, we absolutely share that passion. There is nothing like seeing a shark in the wild – it’s a moment that stays with you forever!” says Holly Bredin, Sales & Marketing Manager, Diverse Travel.
“We’re delighted to celebrate our 10th year of business by becoming a Corporate Patron of the Shark Trust. This is an exciting partnership for Diverse and our guests. We will be donating on behalf of every person who books a holiday with us to contribute towards their vital shark conservation initiatives around the world. We will also be working together with the Trust to inspire divers, snorkellers and other travellers to take an active role – at home and abroad – in citizen science projects and other activities.”
Paul Cox, CEO of The Shark Trust, said:
“It’s an exciting partnership and we’re thrilled to be working with Diverse Travel to enable more divers and travellers to get involved with sharks and shark conservation. Sharks face considerable conservation challenges but, through collaboration and collective action, we can secure a brighter future for sharks and their ocean home. This new partnership takes us one more valuable step towards that goal.”

Shark Trust Asks Divers to help with Shark Sightings this Global Citizen Science Month
Whether you are stuck for ideas of what to do with the kids or are off on the dive trip of your dreams. You can get involved in Citizen Science Month and help the Shark Trust by providing vital data about sharks are rays both close to home and further afield.
In addition to reporting the sharks and rays you see on your dives, the eggcases you find on the beach, the Shark Trust is looking for some specific data from divers who are asked to report any Oceanic Whitetip and Basking Sharks.
Oceanic Whitetip Sharks
The Shark Trust are looking specifically for Oceanic Whitetip Shark sightings over the coming weeks and months. So, if you are diving anywhere in the world, please report your sightings via the website or app.
Website: https://recording.sharktrust.org/
App: Search The Shark Trust in your app store
The Oceanic Whitetip. Known for their incredibly long dorsal and pectoral fins, this species was once the most abundant oceanic-pelagic species of shark on the planet.
Large and stocky, they are grey or brown above, and white below and famous for their huge rounded first dorsal fin and paddle-like pectoral fins. The fins also highly prized within the shark fin trade. Whilst they are mostly solitary, Oceanic Whitetips do occasionally hunt in groups.
An inquisitive species, they were easy prey for fisheries. Combined with their low reproductive rate, they were inevitably at high risk of population depletion. And declines of up to 99% have been reported in certain sea areas. They are listed as Critically Endangered on the IUCN Redlist (2019).
Conservation efforts to discourage further declines include listing on CITES Appendix II and CMS Appendix I. They’re also the only species prohibited from take by all the Tuna RFMOs (Regional Fisheries Management Organisations). However, these measures do not mean that Oceanic Whitetips are not still caught – whether targeted or as bycatch – in some parts of the world. With populations declining at such a high rate, effective implementation of management measures is essential to ensure that the species can recover.
If you are lucky enough to get an image of an Oceanic Whitetip and you record your sighting on the Shark Trust app or website YOU CAN WIN! All images submitted with sightings, that also give consent to use in conservation messaging, will be in with a chance to win an Oceanic Whitetip T-shirt and mug. The competition will run until the end of “Shark Month” in July – so keep those sightings (and images) coming in.
Basking Sharks
Basking Shark (Cetorhinus maximus) season is upon us, and the Shark Trust is asking everyone to keep an eye out for these majestic giants over the summer months. If you see any, you can record your sighting to the Basking Shark Sightings database.
Each year, these mighty fish return to British waters to feed on plankton. You may see one, (or a few if you’re really lucky) from around April-October. They can be seen feeding at the surface of the water, where they look like they’re basking in the sun. Thus, their name!
Sighting hotspots around the British Isles include southwest England, Isle of Man, north coast of Ireland, and western Scotland. The Sea of the Hebrides is the most prolific sightings area in Scotland, but they have been spotted all around the coast and have even ventured into some of the sea lochs. The Shark Trust has received thousands of sightings since the Basking Shark project began, but more data is needed to truly understand what is going on with population numbers and distribution. You can help by recording your sightings this summer.
Great Eggcase Hunt
The Shark Trust has an Easter Egg Hunt with a difference for you to try. Take part in the Great Eggcase Hunt and get involved with a big citizen science project that helps shark, ray and skate conservation. And it’s an enjoyable activity for all the family.
The Shark Trust also want snorkellers and divers to record their underwater eggcase findings. Underwater records help pinpoint exactly where sharks and skates are laying their eggs and can help link to beach records. Learning the depth and substrate that they lay on also helps better understand the species.
