Forever chemicals: Brussels' mission to clean up Europe's water
These were the conclusions of the European Water Resilience Strategy, adopted on Wednesday in Brussels.
In 2022, out of 1,300 monitoring sites in Europe, 59% of rivers, 35% of lakes and 73% of coastal waters exceeded the environmental quality standard for perfluorooctanesulphonic acid (PFOS), a type of PFAS, according to the European Environment Agency (EEA).
In Europe, only 37% of surface waters are in good or very good ecological health and 29% have achieved good chemical status, according to the agency.
Environmental associations, which are campaigning for a ban on PFAS at the source, are denouncing this as a "missed opportunity".
"We expected to see more ambition to reduce pollution at the source," said Angeliki Lyssimachou, head of science and policy at the Pesticide Action Network (PAN) Europe.
Per- and polyfluoroalkyl substances are dubbed "forever chemicals" because they don't easily break down in the environment and accumulate in humans and animals over time.
Health costs are estimated at €52 to €84 billion a year and some of the chemicals have been classified as carcinogenic.
These chemical compounds are non-stick, waterproof and resistant to high temperatures. They are also present in many everyday items such as non-stick frying pans, fire-fighting foams and medical devices.
Jessika Roswall, the European Commissioner for the Environment and Water Resilience said she was in favour of banning PFAS in consumer products such as cosmetics and food packaging. However, she stressed that it would be difficult to ban all PFASs, as some do not yet have an effective alternative.
"The problem is that we need PFASs for many different products. For example, medical products like inhalers (...) or many things for which there is no substitution. In terms of the ecological transition, semiconductors, digitisation or the defence industry," Roswall told Euronews.
In a leaked document, the Commission's estimated range for the annual cost of PFAS decontamination in Europe was wide, at anywhere from €5 all the way to €100 billion. For the water sector alone, the cost could increase to up to €18 billion annually for drinking water treatment.
For some pollutants, such as TFA (trifluoroacetic acid, a type of PFAS), the clean-up is not so simple.
"According to the water companies, it's a very expensive process that involves extracting all the minerals from the water and adding them back. At the end of the day, you're going to lose a lot of water," says Angeliki Lyssimachou. "So you're going to consume a lot more energy.
The Commission wants to apply the "polluter pays" principle and reserve public funding for sites where it has not been possible to identify who is responsible.
The European Water Resilience Strategy aims to restore the water cycle and ensure access to clean, affordable water at a time when Europe is facing extreme weather events such as floods and droughts. 34% of the EU is affected by water shortages.
"Water is life. Water resilience is essential for our citizens, our farmers, the environment and businesses. The Commission's Water Resilience Strategy sets out the path towards a sustainable, resilient, smart and competitive water economy. We must act now to protect this resource," said European Commission President Ursula von der Leyen in a statement.
The European action plan also includes raising awareness for these issues through public debates, increasing European funding for infrastructure modernisation, supporting digitisation through the EU's Copernicus Earth observation programme, and supporting innovation.

Top Japanese fighter retires to support comatose boxer brother
Former WBC strawweight champion Yudai Shigeoka's brother Ginjiro collapsed after a fight in Osaka three months ago and underwent emergency brain surgery. The 25-year-old remains in a coma but is no longer in a life-threatening condition, the Japan Boxing Commission says. Ginjiro, a former IBF champion at the same weight who has a professional win-loss record of 11-2, was recently transferred to another hospital. "I encourage him every day, telling him not to give up and to do his best, so that the flame in his heart does not go out," Yudai, 28, said in an Instagram post on Wednesday. "I believe it is my role as his older brother to enrich his life from now on." "Plans are progressing steadily. That is why I have decided to retire. I have no regrets. The real challenge begins from here on out," added Yudai, who has a 9-2 record. Japanese boxing is under the spotlight after super featherweight Shigetoshi Kotari and lightweight Hiromasa Urakawa, both 28, died days after injuries they sustained in separate bouts in Tokyo on August 2. Japanese boxing officials held an emergency meeting this week and vowed to introduce new safety rules. New measures to be implemented as soon as possible include urine tests for measuring dehydration and stricter rules on boxers' rapid weight loss, said Tsuyoshi Yasukochi, secretary-general of the JBC. Ambulances will also be required on site, even for non-world championship bouts, something which is common practice in some other countries.

Japan boxing to hold emergency meeting following deaths
Super featherweight Shigetoshi Kotari and lightweight Hiromasa Urakawa, both 28, fought on the same card at Tokyo's Korakuen Hall on August 2 and died days later following brain surgery. The Japan Boxing Commission (JBC), gym owners and other boxing officials are under pressure to act and will hold an emergency meeting on Tuesday. They are also expected to have talks about safety next month, local media said. "We are acutely aware of our responsibility as the manager of the sport," Tsuyoshi Yasukochi, secretary-general of the JBC, told reporters on Sunday. "We will take whatever measures we can." Japanese media highlighted the risks of fighters dehydrating to lose weight rapidly before weigh-ins. "Dehydration makes the brain more susceptible to bleeding," the Asahi Shimbun newspaper said. That is one of the issues the JBC plans to discuss with trainers. "They want to hear from gym officials who work closely with the athletes about such items as weight loss methods and pre-bout conditioning, which may be causally related (to fatalities)," the Nikkan Sports newspaper said. In one immediate measure, the commission has decided to reduce all Oriental and Pacific Boxing Federation title bouts to 10 rounds from 12. "The offensive power of Japanese boxing today is tremendous," Yasukochi was quoted by the Asahi Shimbun as telling reporters.

'Heat island' effect: Will European cities become unliveable?
The summer of 2025 has again been marked by several successive heatwaves, which have gripped large swathes of Europe. Nowhere are the effects of this extreme weather more intense than in the continent's urban areas. This is due to the Urban Heat Island (UHI) effect, which significantly raises temperatures compared to surrounding (rural) areas, intensifying heatwaves. "This urban heat island effect is impacting cities all over Europe, and this makes temperatures about two, three, sometimes even four degrees warmer in cities compared to the rural environments," Niels Souverijns, climate expert at VITO in Belgium, told Euronews. Surface temperatures in cities were sometimes up to 10-15°C higher than in their rural surroundings during summer, data from the European Commission's Joint Research Centre shows. These figures are particularly concerning given the large number of people affected. Almost 40% of Europe's total population lives in cities, while around 70% resides in urban areas. The phenomenon is a major health concern for city authorities across Europe. One study by NOVA National School of Public Health in Portugal found that hospital admissions increased by 18.9% from the baseline on heatwave days, straining healthcare systems. Vulnerable groups — like the elderly and young children — are particularly at risk. "Especially the elderly with underlying health conditions, for example, respiratory illnesses or cardiovascular illnesses, are worst affected," said Souverijns. As the phenomenon plays out mostly at night, people don't cool down properly when going to sleep, which also has negative health effects. Concrete jungle This urban heat island effect is the result of several factors, ranging from the widespread use of materials to the concentration of buildings and heavy traffic. "The fact that the city is warmer than the surrounding area is due to the materials used in the city," climate scientist Wim Thiery (VUB) told Euronews. These include asphalt and cement, which "absorb heat when the sun shines, retain it and then radiate it at night". As a result, during the day, the maximum temperature in cities is warmer, but at night, the temperature also cools down less. Tall buildings and narrow streets also drive this phenomenon, as they heat up the air that gets trapped between them, blocking the natural flow of wind that would otherwise assist in cooling the air. In many cities, this is particularly true in poorer urban areas characterised by dense and sometimes unregulated urbanisation. This factor, in combination with poor housing conditions, lack of insulation and reduced access to cooling options such as green spaces, makes the urban heat island effect a socio-economic issue. "In the richer neighbourhoods located just outside city centres, there tends to be more greenery," Thiery said. This is the case in Brussels, for example, where the wealth divide correlates strongly with access to natural areas, with the poorest suffering an acute shortage of trees and parks. Souverijns noted that the magnitude of the urban heat island is strongly correlated with the size of the cities and the amount of concrete and buildings located there. "So bigger cities, which have more concrete and more buildings, tend to be more impacted." Finally, the amount of traffic in a city also has an impact. Pollution from cars, for example, can act as a type of greenhouse gas layer over a city, trapping hot air. Green solutions Climate scientist Wim Thiery emphasised that, in the future, the urban heat island effect is expected to worsen. "Due to climate change, temperatures are increasing by more than the average temperature of 2°C in general, with heat days being 4°C warmer in Europe," he told Euronews. Cities can, however, adopt a range of measures to counteract the urban heat island effect. This includes creating wind corridors for ventilation, designing green roofs and façades for buildings, planting more vegetation and making better use of water. "In essence, we have to redesign cities to remove as much concrete as possible," said Souverijns. The Brussels region is particularly vulnerable to heatwaves compared to other Belgian municipalities. The difference can be as much as 10° compared to rural areas. One of its 19 communes, the City of Brussels, provides residents with additional information about precautions or behaviours that are best to adopt on hot days, including through interactive maps with which they can find drinking water points, museums, fountains, shaded green spaces and other places where they can protect themselves from the heat. "More structurally, we are of course committed to physically adapting and improving our living environment by planting trees, softening surfaces, making squares and streets shadier and greener, bringing water into the city and creating green-blue networks," Frederik Ceulemans, alderman for climate in the City of Brussels, told Euronews. "There are additional interventions that we want to test soon, such as shaded structures, whether temporary or permanent." 'Adaptation alone is insufficient' However, both experts agree that adaptation alone is not enough. "We have to be realistic that the impact of adaptation is limited. Very locally, where trees are planted, the impact can be noticeable, but on one street further, it will be warmer again," Thiery said. That is the reality of cities: there is no room for sufficient green spaces in densely populated neighbourhoods. He added that, if authorities want to stop this issue, mitigation must be top of mind. This was mirrored by Souverijns. "The urban heat island effect will also increase towards the future with additional climate change. So it's also important to reduce our emissions as fast as possible." In the City of Brussels, the focus is on sustainable renovations of buildings, which account for 60% of CO2 emissions in the region, as well as sustainable plans for mobility and energy. The region aims to reduce CO2 emissions by 55% by 2030 and become climate-neutral by 2050. If CO2 emissions are not reduced to zero, experts warn that "a tsunami of heat" will descend onto cities, which could become unlivable. "We already see these kinds of unlivable cities, mainly in India and in countries close to the equator. Here, people are struggling to live in the city and go about their daily business," Souverijns said.
