Besides the dust that cloaks pathways, windowsills and gardens, the towering grey heaps of discarded rock are another unwelcome reminder of the platinum mine next door to the South African township of Chaneng.

In and around the city of Rustenburg, the low-grade platinum ore that has made South Africa the world’s top producer of the silvery metal creates massive waste piled in large rocky heaps known as tailings. For every tonne of metal extracted, hundreds of tonnes of waste rock is left behind in huge piles.

The transition to cleaner energy system is expected to push up global demand for platinum group metals (PGM) – which include palladium and other precious metals, as well as platinum. They are used in hydrogen-related technologies such as fuel cells and electrolysers that split water molecules as well as in hybrid cars that need catalytic converters to curb pollution.

To secure supplies, mining companies are starting to make use of what was once considered waste.

Reprocessing mine tailings using new technology can be a more sustainable form of producing minerals and metals needed for the energy transition because it is expected to reduce the size of existing waste heaps and boost output without the need to open new mines, which can cause more environmental destruction and community displacement.

“Tailings reprocessing offers genuine benefits, reducing pressure for new mining [and] addressing existing environmental liabilities,” said Mathikoza Dube, an expert on critical minerals based in Rustenburg.

“It offers the world a pathway to secure supplies of energy transition minerals while remediating waste that’s contaminated communities for generations,” Dube added, cautioning it is not a “magic solution” and should be approached in a way that ensures local communities benefit.

In Chaneng, where the tailings dumps loom over backyards, residents are wary.

“Same theft in new clothes”

They fear the plan to reprocess mining tailings at the neighbouring mine – operated by South African platinum miner Sibanye-Stillwater – is being dressed up as sustainable when in reality it will mean more contamination, blasting, dust and no end to their community’s problems.

Despite decades of mining, unemployment in the area remains high, many people say they never received compensation for the loss of their agricultural land and most households still lack access to basic sanitation infrastructure.

Water testing carried out by SRK Consulting in 2009 found elevated nitrate levels exceeding World Health Organization guidelines in community boreholes, and health practitioners document dramatic increases in respiratory diseases.

“Now they want to dig up the waste piles and call it progress? Show us the ownership papers. Show us the rehabilitation plan. Otherwise, it’s the same theft in new clothes,” said Johannes Kgomo, a community leader.

    South Africa’s mining legislation requires that 26% of mining assets are held by historically disadvantaged people including Black South Africans, and Chaneng residents are demanding a stake of 15% to 30% in any tailings operation on their land, allowing them to have a say in how the business is run.

    They say that should be granted to them as compensation for the health and environmental problems they have endured as a result of the mine.

    The community is also demanding comprehensive water testing and treatment, adequately resourced clinics with respiratory specialists, compensation for destroyed agricultural land, infrastructure repair and long-term health monitoring.

    “We are not asking for handouts,” said Gideon Chitanga of the National Union of Mineworkers, which often takes the side of local communities in disputes with companies.

    “These people have already paid with their health, their water, their land. That contamination, that suffering – that is their investment. Now they want returns and decision-making power,” Chitanga added.

    A spokesperson for Sibanye-Stillwater declined to comment.

    A mining industry source, who asked not to be identified, said conversations with community members were ongoing.

    “Nobody disputes these communities have suffered. The question is how to structure ownership in a way that’s legally sound, financially viable, and genuinely empowering,” the source said.

    New technology boosts metal recovery in waste

    New reprocessing technology has made it economically viable to extract platinum group metals from tailings, and several operations are already underway in South Africa’s platinum mining belt, around the city of Rustenburg.

    Sibanye-Stillwater already operates multiple retreatment facilities, processing thousands of tonnes of waste ore monthly.

    Another South African miner Tharisa processes chromite from PGM tailings commercially. Chromite is used to obtain chromium, a metal used in the manufacture of wind turbines and some energy storage batteries.

    “Historical tailings facilities contain economically viable concentrations that were unrecoverable with older technology,” said Leo Vonopartis from the University of the Witwatersrand’s BUGEMET research programme, which studies the geology of South Africa’s Bushveld Complex mining belt.

    Tailings in the area around Rustenburg can contain up to 2.5 grammes per tonne of combined platinum, palladium and rhodium – along with chromite. Vanadium, cobalt and rare earth elements have also been found.

    At current prices, which have rallied this year, it is worth extracting the rare metals, despite the challenges.

    Breaking with the cycle of extraction and injustice

    “The technology exists. The economics work. The question is whether we can structure these projects to genuinely benefit the people who have paid mining’s costs,” a spokesperson for one mining company said, asking not to be named.

    Without that, local expert Dube said, the reprocessing of tailings is scarcely better than other forms of mining.

    “Reprocessing tailings does not erase the damage that created them. If it is structured as extraction by another name – where companies profit and communities remain marginalised – we have just found a new way to perpetuate old injustices.”

    Gesturing toward the tailings dam visible from her yard, Noxolo Mthembu recalls the days when her vegetable patch used to feed the family.

    “We used to grow spinach, tomatoes, pumpkins,” she told Climate Home News. “Now nothing grows. The dust kills everything. My children have asthma. My husband died of lung disease at 54.”

    Like many of her neighbours, she says any new cycle of mining activity – this time in the name of the clean energy transition – must not repeat the past.

    “Show me the ownership papers with our names. Show me the water treatment plant. Show me the clinic with enough staff. Then I will believe this time is different.”

    Sewing and Painting the Future

    The iconic Greenpeace ship hosts community and family activities over the weekend from 27-30 April, including banner-making workshops and tours of the ship, culminating in a community paddle out for the climate and ocean at South Beach.

    The banner drop is a distinctive part of the Greenpeace repertoire.

    The moment of the unfolding is intrinsically dramatic. It is the reveal; when the moral and scientific truth of a situation is unveiled to the world. The wrong is being labelled—not through a written submission, or a social media post, or a statement in a meeting—but in words emblazoned in real physical space, chosen and occupied with precision, for all to see. There is jeopardy and transgression. And there are consequences—for the activists and for Greenpeace, as well as for the target of the communication. One of the reasons the banner remains such an effective tool in our toolbox is because of its undeniable clarity in cutting through, driving change and accountability in a way that few other tactics can. It is naming the wrong: in giant, clear letters.

    We’ve hung these massive messages at environmental crime scenes, corporate headquarters, and iconic landmarks; on government buildings, ships and planes—in locations all around the world, for years.

    My own memories unfurl even as I write this, but because the campaign to stop Woodside at Scott Reef is so pressing, what immediately springs to mind are two of our banners in that campaign: one on a crane outside their Perth HQ, and another on some of their corroding industrial junk at sea. What about you? Is there a particular banner that you picture when you think of Greenpeace?

    The banners can attract global attention, but they have quiet beginnings. Each one is made by hand, often by volunteers. It is the invisible labour behind each spectacular public moment. One of the key pieces of equipment in our workshop at Rainbow Warrior House is the sewing machine. Sometimes our workshop is full of people and noise; at others it is quiet, the only sound being the gentle, purposeful, whir and buzz of a banner being sewn. It is usually our warehouse manager, Kieran Holmes, on the tools, head over the machine, carefully pouring over the raw canvas or tarp as the banner takes shape. Kieran’s one of those people who seems to be able to turn his hand to almost anything, but you wouldn’t know it because he’s old-school modest. In addition to being incredibly skilled, Kieran’s an all-round beaut human to have in the heart of our headquarters; never too busy to take the time to show a newcomer, or curious visitor, around his domain. 

    Once the banner is sewn up, the lettering needs to be outlined. This is done on a magnetic wall—a fit-for-purpose feature at Rainbow Warrior House, where the banner is held up with magnets, and the edges of the letters neatly traced from a projection.

    Next comes the painting. It usually starts late in the afternoon, sometimes going into evenings and weekends, with volunteers, staff, mates crowded around, brushes in hand. It is a calming meditative feeling of shared purpose, giving each letter its visual heft, the colour building power and presence with each stroke.

    Then you stand back, stretch, and look at the message, now ready.

    S A V E S C O T T R E E F

    Throughout history, every great push for social change has required some form of invisible labour; preparation in the form of quiet things seldom seen, but vital. It is the enabling work of love instantiated in action. And of course, so much of the time it has been women who have done this labour, so that the men could get the chance to make the speeches and stand on the podiums. The inaugural Greenpeace voyage to stop nuclear testing in 1971 had a male-only crew, but wouldn’t have happened without the ideas and work of women behind the scenes.

    It is what we do together, after all, that changes the world. Sometimes that work happens on a stage, a ship on the wild seas, or up the side of a building. But mostly, it is the hidden diligence of those who care and contribute to all the enabling work that makes a change once thought impossible, inevitable. It is Kieran at his sewing machine. It was Dorothy Stowe doing the administrative work of the ‘Don’t Make A Wave Committee’ that became Greenpeace.

    When we think of social change, it is the sturm and drang that we remember. The drop of the banner, the chant of the crowd, the raising of the new flag. But look behind the curtain, and there’ll be a crew of people who are taking responsibility for the administration, the sewing and the painting, making the food, checking the bus timetables, getting stuff done. And behind them are even more handsinvisibly donating time and trust; the financial, material and expert resources that make it all possible. There’s love, camaraderie and know-how at every stage.

    We are social and cooperative creatures by nature. And we human beings have been stitching for millenia, sewing the possibilities of our common future. Political and corporate bullies and algorithmically manipulative platforms would have us forget this, and abandon who we are. But we should be in no doubt that the brighter prospects for ourselves and life on earth continue to be stitched and painted; collaboratively and with love, by the diligent hands of millions of people who care, each day, in every community and city across the world.

    With Love,

    David


    Q & A

    I always get great questions when interviewing prospective new team members. One that came up again recently was: “Is Greenpeace actually one organisation?”

    Around the world, people know Greenpeace by our one global name, united by a shared mission: securing an Earth capable of nurturing life in all its magnificent diversity, with a particular focus on climate and biodiversity. Behind the scenes, though, we’re organised as a network of 25 legally autonomous national and regional offices, including Greenpeace Australia Pacific, working alongside Greenpeace International.

    That structure gives us the best of both worlds: we work together leveraging the power of a global network on the issues that matter most, while each office remains legally independent and deeply connected to the communities, cultures and political realities where we’re embedded. Local knowledge informs global action, and global collaboration strengthens and supports local campaigns.

    It’s a model that has enabled Greenpeace to take on some of the world’s biggest challenges for over five decades–while withstanding challenges and attacks from governments and corporations. Global enough to tackle global problems, local enough to understand our communities and the natural places we love.

    As fires burn and temperatures soar, it’s time to imagine a world beyond GDP

    Published

    on

    Steven Stone is acting director of the United Nations Environment Programme’s Office of Science

    In 1934, American economist Simon Kuznets presented a paper to Congress advocating for a new way of measuring economic performance.

    The United States was reeling from the Great Depression, and Kuznets – a future Novel prize winner – wanted to gauge just how badly the country’s economy had been dented.

    His metric, which would come to be known as gross domestic product (GDP), was a breakthrough. But as pioneering as it was, Kuznets saw its limitations.

    “The welfare of a nation can scarcely be inferred from a measure of national income,” he wrote in the 1934 paper.

    Some nine decades on, we have largely forgotten that message. GDP has become a barometer of economic progress, a kind of one-number-that-rules-them-all upon which national policies turn and governments rise and fall.

    With the climate crisis deepening by the day – as evidenced by the heatwaves and wildfires now searing Europe – our attachment to GDP is looking like a problem.

    In a single-minded pursuit of GDP growth, humanity is inadvertently feeding several environmental crises that, over the long run, threaten to make most of us poorer, sicker and more miserable. Climate change alone could slice 20 per cent off global GDP by 2100 – a staggering number.

    Clear-cutting boosts GDP not wealth

    We need to broaden our vision and definition of economic success before it’s too late.

    I grew up in the 1970s and 80s surrounded by the mixed hardwood forests of the northeastern United States. For me, the trees were a refuge, a place to run, discover and savor the history and mystery of the land and its people.

    Those experiences with my friends were more important than the amount of money in my pocket. And they led to a realization early on in my career as an economist: that wealth is about more than just income.

    This is one of GDP’s most significant oversights.

    With every forest we clear cut and every ounce of fossil fuel we burn, GDP rises. But through those actions, we are whittling away at the natural world, which supplies us with food, water, medicine, clean air and countless other essentials.

      By focusing only on GDP, we’re ignoring what’s happening to the natural assets on which our prosperity ultimately depends. It’s like we’re driving a car and only looking at the speedometer, not the energy remaining in the battery.

      That is the difference between measuring income versus measuring wealth.

      The answer to this dilemma lies in looking beyond GDP. We must start considering a broader range of indicators when making policy decisions.

      From an environmental perspective, that means measuring and valuing natural assets like forests, water, soil, biodiversity and clean air. By assigning a value to nature, decision-makers can better understand the economic consequences of, say, strip-mining a mountain top or letting plastic waste overwhelm a river.

      There is still some debate over how exactly to do this kind of natural capital accounting. But that’s not a reason to dismiss it, as many have done. It took years of refinement to end up with the GDP formula we have today.

      Costa Rica’s example

      The idea of looking beyond GDP isn’t only a theoretical debate. Countries and communities around the world have started to make economic decisions based on their natural assets. A prime example is Costa Rica, a biodiversity hotspot where a years-long effort to conserve land and seascapes has led to a boom in tourism. That in part helped elevate the country into the club of high-income nations.

      This kind of environmentally focused economic decision making can pay huge dividends. By stabilizing the climate, ending pollution and halting the loss of the natural world, humanity could save millions of lives a year and create US$20 trillion in economic benefits annually by 2070, found the Global Environment Outlook 7, a 2025 report from the United Nations Environment Programme (UNEP). The report was funded by the European Union among others.

      I began my career as an economist before moving to UNEP, which focuses on solving the world’s thorniest environmental problems. During that time, I’ve come to appreciate that “wealth” means more than simply “income.” True prosperity means being able to provide for ourselves now and into the future. Anything short of that is an empty kind of affluence – and ultimately doomed to be short-lived.

      As deadly heat blankets our cities, species slip into extinction and the planet struggles with rising toxicity and pollution, I am convinced that we can do better at measuring what matters. And that means updating and expanding how we measure economic progress.

      When taps run dry in the Caribbean, it’s not enough to blame El Niño

      Published

      on

      El Niño, likely to be one of the strongest in modern history, has arrived on Caribbean shores.

      Drought is slowly creeping up on our islands. But unlike the fiery wildfires ravaging parts of Europe, there’s no smoke signalling the damage being done, no sirens to warn of the danger. Only announcements from public health officials to stay indoors and remain hydrated — as if outdoor workers and farming communities have the luxury to heed such advice.

      During El Niño, strong atmospheric winds alter rain patterns and trap heat across the Caribbean. But while we have experienced El Niño many times before, it has become very visible in recent years how climate change is making this natural phenomenon worse.

      Across the Greater Antilles, temperatures are soaring past 38°C (100°F), with real-feel indexes reaching a gruelling 43°C in parts of Puerto Rico where I live. Cuba has it worse. Widespread power outages mean that methods for cooling down are unavailable for most of the day, leaving millions of vulnerable people at risk of heat stroke when temperatures hit 38°C.

      Santa Marta coalition tested as co-chair Colombia turns back to fossil fuels

      During the last strong drought a decade ago, I had water only two days a week in my home. Today, there are many families whose taps are about to run completely dry. Water authorities have already begun strict rationing in some municipalities, with more on the list scheduled for rationing if conditions don’t change.

      Water rationing is far more than an inconvenience; it is an immediate health risk. This means thousands of people need to constantly haul heavy buckets up flights of stairs just so they could bathe, cook, stay hydrated – the basics of survival.

      Heat causes health problems

      Puerto Rico is home to roughly 300,000 elderly residents. Many live alone, isolated and without support. They risk severe physical injury when carrying heavy water containers, and are wont to suffer from silent heat exhaustion in unventilated rooms.

      Furthermore, when water shortages force residents to store water in open household containers, it inadvertently creates breeding grounds for Aedes aegypti mosquitoes. Paired with scorching temperatures that tend to shorten the mosquito breeding cycle, the region is facing explosive outbreaks of dengue fever that endanger our most vulnerable: children and the elderly.

      The economic fallout is equally devastating. Dry fields mean millions of dollars in lost crops, forcing small agricultural businesses to collapse, needing urgent government relief to survive. Extreme fuel shortages have already paralyzed Cuba’s agricultural sector, cutting food output by 60% – the El Niño dry spell threatens to decimate it.

      At sea, warmer ocean waters fuel massive influxes of sargassum seaweed. Rotting sargassum chokes our beaches, destroying the local tourism industry that so many working families rely on. Tangled seaweed also damages nets and boat engines, slashing fish catches and driving up equipment costs for local fishers.

      In the south of Puerto Rico, the coastal town of La Parguera is currently witnessing a historic amount of sargassum on its shores. This has halted most of the boating activity in the area, which is the seaside town’s main tourist draw and economic driver.

      All over the Caribbean, from town halls to local group gatherings, the story I hear is always the same: constant headaches, lost work hours, failing health, and a sense that quality of life is silently being stolen. The compounding effects of heatwaves, drought, and marine destruction are exhausting our people, our islands.

      Climate change to blame

      Climate change makes each El Niño year hotter and more damaging. Higher baseline global temperatures increase the energy and moisture available for extreme weather. Latest projections show that El Niño may push the monthly global average temperature past 2°C of warming for the first time in early 2027. In the Caribbean islands, that will not just be breaking records – it’ll be breaking lives.

      Recently, I had the opportunity to share a panel with climate scientists behind what is known as the field of “attribution science” – or the science that compares today’s climate conditions to what the Earth’s climate would be like without human activity, particularly burning fossil fuels. They’re unequivocal: it’s no longer a question of whether extreme weather is caused by climate change, it’s just a question of how much.

        Attribution science recently got a boost from the U.S.’ top scientific advisory body. The National Academies of Sciences, Engineering and Medicine recognized that researchers’ methods have advanced considerably in recent years, resulting in better assessments on how much extreme weather can be attributed to human-caused climate change. It noted that attribution findings could be relevant in some types of legal cases, including those seeking damages from oil companies for climate impacts.

        This crisis, which is already taking a heavy toll on our communities’ survival, needs real, urgent, and structural action that goes beyond aid. With similar droughts now gripping parts of Asia and Africa, we’re falling into the familiar narrative of treating the looming humanitarian crisis as if no one was to blame, as if it is being caused solely by a natural phenomenon we can’t control.

        It’s not. The world was already on fire before its regular visitor, El Niño, came. While we need humanitarian action, we need climate action too, in order to permanently put out the flames.
