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.”

Paul Watson Released as Denmark Blocks Japan’s Extradition Bid
Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.
The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.
Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.
In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.
Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.
Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.
The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.
Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.
Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.

12 Days of Zero-Waste Fish-mas
This holiday period, the Marine Conservation Society, the UK’s leading ocean membership charity, invites you to make some simple changes to eating fish this Christmas to help our seas.
Dr Kenneth Bodles, Head of Fisheries and Aquaculture at the Marine Conservation Society, said, “During the festive season, our consumption increases, but so does waste. Sustainability isn’t just about where food comes from – it’s also about how you use it. By reducing waste and making the most out of your seafood, you’re not only taking steps to be more ocean-friendly, but can also help to cut costs during what is often one of the most expensive times of the year”.
The Marine Conservation Society has compiled twelve tips on how to consume seafood sustainably with zero-waste this Christmas:
Buy whole fish instead of fillets
Instead of fillets, consider buying whole fish such as salmon, hake, or lemon sole. By adopting a “nose to tail” approach with cooking, whole-baked fish not only feeds a crowd, but also helps to minimise waste and maximise sustainability by using up every part of the animal, including bones, skin, and fat.
Make fish stock
Leftover fish bones or shells can be put to good use by boiling them to make a nourishing fish stock or bisque. This can be frozen and preserved for later use and makes for a flavourful base in a soup.
Make your own fish pâté
Avoid waste by turning leftover fish, such as smoked mackerel or salmon, into a delicious pâté by blending with cream cheese and lemon. Perfect when paired with crackers.
The sustainability of salmon and mackerel varies depending on where and how it is caught or farmed. For more information on green-rated options, check the charity’s Good Fish Guide.
Buy frozen
By purchasing seafood that is frozen or vacuum-packed, this helps to reduce waste by extending the shelf life of your food.
Fish pie
If you’re wondering what to do with leftover cooked fish, why not opt for a classic fish pie with mashed potatoes, leeks, and a cheesy sauce? A sure crowd pleaser on Boxing Day.
Use the head
Don’t forget the fish head! The meat is incredibly tender and flavourful. The charity recommends a cod’s head curry or recreating Fallow’s renowned cod’s head in siracha butter.
By stretching your ingredients further, not only is this a more sustainable way to enjoy seafood, but also cost-effective by repurposing leftovers and cooking creatively.
Boxing Day brunch
Mix leftover kippers or smoked salmon with scrambled eggs for a tasty, zero-waste, Boxing Day brunch.
For best choice, make sure you buy kippers, or herring, from the North Sea and the North Irish Sea.
Zero-waste storage
A top tip from the Marine Conservation Society to avoid waste is freezing fish offcuts to save for future use.
Crisp up the skin
Even leftover fish skin can be turned into a quick savoury snack by crisping it up in an air fryer with a little olive oil and salt.
Anchovies two ways
Leftover anchovies can either be blended with butter to make a delicious anchovy butter or tossed into pasta for a hit of umami flavour.
The charity recommends opting for anchovies caught in the Bay of Biscay for best choice.
Fishcakes
For an easy, zero-waste meal, leftover seafood trimmings can be mixed with mash and fried in breadcrumbs to make fishcakes.
Pickled mussels
Try pickling mussels in 1:1 vinegar and water, with a dash of sugar for a sustainable, zero-waste snack that can be enjoyed well beyond the festive season.
Mussels farmed in the UK are a seafood superhero. Grown using low-impact methods and harvested by hand, they get all the food they need from the sea around them. This makes them one of the most sustainable, ocean-friendly, and cost-effective seafood options.
Players of People’s Postcode Lottery have raised £6.6M towards the Marine Conservation Society’s vital work in making seafood more sustainable.
Laura Chow, Head of Charities at People’s Postcode Lottery, said: “Fish is a festive favourite for many, but making sustainable choices when it comes to how we buy and eat seafood makes all the difference for our ocean. Support from players of People’s Postcode Lottery has helped the Marine Conservation Society further its sustainable seafood work, so that we can all enjoy healthier, better protected seas.”
The Marine Conservation Society encourages you to make sustainable seafood choices a year-round habit, not just for Christmas. To check how sustainable the seafood on your plate is, you can visit the charity’s Good Fish Guide. The Guide helps consumers and businesses identify the most sustainable seafood using a simple traffic light system, based on where and how species are caught or farmed. Green is the best choice, amber means improvements are needed, and red indicates fish to avoid buying.
Zero-waste gift idea
Why not embrace a zero-waste Christmas by gifting a membership to support marine conservation? It’s a meaningful, low-waste gift that helps protect our ocean for generations to come. Memberships start from as little as £5 a month – the price of a sandwich and drink from your local coffee shop.
