The finance ministers of Brazil and France pushed this week for a tax on US-dollar billionaires of at least 2% of their wealth each year, with the $250 billion it could raise going to tackle poverty, hunger and climate change.
Brazil’s Fernando Haddad and France’s Bruno Le Maire promoted their proposal at the Spring Meetings of the World Bank and International Monetary Fund (IMF) in Washington, alongside IMF head Kristalina Georgieva and Kenyan finance minister Njuguna Ndung’u.
“In a world where economic activities are increasingly transnational, we have to find new and creative ways to tax these activities [and] thus direct the revenues to common global endeavours such as ending hunger and poverty and fighting climate change,” said Haddad.
He called on world leaders to show “political courage”, embrace “innovative solutions based on evidence” and give their people “hope”. “Without courage, there’s no good politics that can be done,” he said.
Speaking next at a briefing in Washington, Le Maire said overhauling the taxation system was “a matter of efficiency and a matter of justice”, and that a levy on the super-rich should follow already-agreed measures for a digital tax and global minimum corporation tax. “Everybody has to pay his fair share of taxation,” he added.

French economist Gabriel Zucman is drawing up a proposal for a billionaires tax that will be presented to G20 finance ministers and central bankers when they meet in the Brazilian city of Rio De Janeiro in July.
Haddad, whose government will host that meeting as G20 chair, said he wanted the Group of 20 big economies to issue a statement of support. Le Maire said he hoped the wealth tax would be in place by 2027, ten years after reform of the international taxation system began.
But at a separate press conference in Washington this week, Germany’s finance minister Christian Lindner rejected the proposal. “We do not think it is suitable,” he said. “We have an appropriate taxation of income.” Lindner is from the free-market Free Democratic Party, part of Germany’s governing coalition with the centre-left and Greens.
Who will spend it?
Zucman said not all countries needed to agree to a measure for it to be implemented. If some countries don’t tax billionaires, others can tax them more to make up for it, he said, adding that is how the global minimum corporation tax rate of 15% – which went into effect this year – works.
While Haddad spoke of tackling hunger and climate change, it is not yet clear who would be in charge of spending the money raised from billionaires or what it would be spent on.

Esther Duflo, another French economist who addressed G20 ministers this week, told journalists the money should be given to developing countries to deal with climate change.
The best use, she said, is for the money to go to poor people before a climate shock like a heatwave hits, for their communities to protect them through measures like air-conditioned public spaces, and to governments for reinsurance against climate disasters.
From academia to politics
A billionaires tax has long been pushed by progressive economists like Zucman and Joseph Stiglitz. But it has been taken from academia onto the political agenda by the G20 presidency of Brazil’s left-wing government led by President Luiz Inácio Lula da Silva and Haddad.
Zucman presented the proposal at a G20 finance ministers meeting in Sao Paulo in February. It was the “first time these issues of inequality, progressive taxation [and] extreme wealth concentration were discussed in such a forum”, he said, adding that the “vast majority praised Brazil for putting those issues on the agenda”.
The main barrier, he said, is that billionaires will fight back against it. “They have a particular hatred for any kind of tax based on wealth. Why? Because that’s the one tax that really works for them,” he said.

But E3G analyst Sima Kammourieh, a former economic adviser to the French government, was more pessimistic about the prospect of a billionaires tax being implemented. She “wouldn’t completely rule it out, but it’s something which could take many many years to come to fruition”, she said.
Although Zucman insisted the tax could go ahead without the US on board, Kammourieh warned that a Donald Trump victory in the US elections in November would be damaging. Joe Biden has called for higher taxes on billionaires, while Trump is one of the world’s nearly 3,000 billionaires.
Elsewhere at the Spring Meetings in Washington this week, France, Kenya and Barbados launched a taskforce to examine how to fill the gap in climate finance for developing and vulnerable countries – excluding China – which will need investment of $2.4 trillion per year by 2030, according to economists Vera Songwe and Nicholas Stern.
The taskforce will consider taxes on wealthy people, plane tickets, financial transactions, shipping fuel, fossil fuel production and fossil fuel firms’ windfall profits. It will also mull redirecting state fossil fuel subsidies to a new global loss and damage fund and windfall taxes on fossil fuel producers when prices are exceptionally high.
The plan is for one or more proposals to be presented to governments with the aim of securing international agreement at the COP30 UN climate summit in Brazil in late 2025.

Global billionaires tax to fight climate change, hunger rises up political agenda
An Lambrechts is a biodiversity politics expert at Greenpeace International with extensive experience in biodiversity-related multilateral negotiations. She is the head of the Greenpeace delegation at the Convention on Biological Diversity (CBD) COP17 happening in Yerevan, Armenia.
In 2022, COP15 delivered the landmark Kunming-Montreal Global Biodiversity Framework to halt and reverse biodiversity loss by 2030. With COP17 starting in Yerevan, we are now halfway to the deadline, and according to the first Global Review of progress, countries are not on track to meet the biodiversity targets, and implementation must accelerate fast.
One of the main findings of the Global Review is that funding falls far short of the scale needed to halt and reverse nature loss. But the crisis facing the world’s biodiversity is not an absolute scarcity of capital – it is a profound public policy distortion.
The global economy currently spends roughly $30 destroying nature for every single dollar invested in its protection. According to a report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, a staggering $2.4 trillion is spent in public subsidies for fossil fuels, agriculture and water use, while global investment in biodiversity conservation and restoration stands at a mere $220 billion.
Countries urged to ramp up “insufficient” nature policies at COP17
Yet, discussions about how to close the biodiversity finance gap continue to claim that salvation lies in mobilising private capital, scaling offsets and “derisking” investments in nature. This is a fundamental misunderstanding of both the nature of ecological stewardship and of the global financial architecture.
Biodiversity conservation is not a speculative investment portfolio – it is the foundation of human survival. The health of our planet is a non-monetisable, non-excludable public good. Expecting profit-seeking private capital to protect nature perpetuates the structural drivers of ecosystem destruction in the first place.
But if private market mechanisms cannot save biodiversity, where will the necessary public resources come from?
Money going to the wrong places
The answer lies in recovering the vast public wealth currently drained by cross-border tax abuse, financial secrecy and corporate impunity. Finance and environment ministers meeting in Yerevan must give a strong political signal that, to avert ecological breakdown, countries need to take swift action to reform global tax rules, eliminate harmful public subsidies and cancel unsustainable sovereign debts for the public revenues to end up where they belong.
Extractive sectors such as industrial agriculture, fishing, timber and mining continue business-as-usual, often heavily subsidised by public treasuries, while voluntary carbon and biodiversity offset markets pose a serious risk to nature conservation. Offset schemes have delivered only a negligible fraction of the funding needed to preserve ecosystems, allowing industries to continue with their destructive business-as-usual practices.

Brazil’s environment minister said the Tropical Forest Forever Facility has raised billions in record time – which he hopes will convince more investors
In advanced economies, public funding often actively undermines biodiversity. In Europe, over €5.3 billion in public subsidies is funnelled annually into intensive forest biomass harvesting under renewable energy directives, degrading primary forest ecosystems and undermining long-term climate resilience. Pleading with private investors to fill a “finance gap” while pouring billions into ecological destruction is an exercise in futility.
Developing countries struggle with debt burden
For developing countries, reliance on private finance is further compounded by a crushing sovereign debt crisis. In 2024, public debt in developing economies reached record levels, with net interest payments alone absorbing $921 billion. A record 61 developing countries now spend more than 10% of government revenue on foreign debt service, with many climate-vulnerable nations spending twice as much servicing external debt as they receive in climate and biodiversity finance combined.
This burden acts as a structural driver of ecosystem destruction. Under pressure from external creditors and international financial institutions to avoid default and secure foreign exchange, governments are routinely forced into austerity measures and pushed to expand raw commodity exports into pristine biomes.
Comment: World Bank and IMF should lead the financial system in responding to the climate crisis
The current negotiations for a United Nations Framework Convention on International Tax Cooperation (UNFCITC) also offer a way forward. An estimated $492 billion in tax revenue is lost every year to offshore tax havens. Multinational corporations account for around $348 billion of this total by shifting profits away from the countries where real economic extraction and environmental degradation occur.
In the mining sector alone, developing nations lose tens of billions annually to corporate tax dodging. Furthermore, international financial secrecy shields environmental criminals, with illicit financial flows from illegal logging draining between $51 billion and $152 billion annually.
At COP17, leaders must seize the opportunity to build a bridge between the two conventions and enhance cooperation. Governments must put the world on a firm path to securing predictable, sufficient, sovereign public finance for biodiversity conservation. It’s the only path to a restorative, rights-based future for people and the planet.

Greenpeace delivers 47 metre-long petition with half a million signatures to Woodside HQ following major gas protest
Greenpeace delivers 47 metre-long petition with half a million signatures to Woodside HQ following major gas protest
PERTH, Monday 19 October 2026 — Dozens of Perth community members delivered a giant petition, signed by almost half a million people, to Woodside’s corporate headquarters this morning, calling on the government to save Scott Reef from Woodside’s reckless Browse gas proposal.
Dressed in sea creature costumes and hats, supporters carried one of Australia’s biggest environmental petitions to Woodside’s headquarters, and a local choir performed a ‘Scott Reef’ rendition of Angie McMahon’s iconic cover of ‘Reckless’ by Australian Crawl.
On the sidelines of the Perth Global Citizen Now event, it comes following a two day-long protest at Woodside’s Scarborough gas platform that saw activists scale and occupy the Floating Production Unit calling to “Stop Woodside’s Dirty Gas” and “Save Scott Reef”. The activists were taken from the platform by police helicopter on Sunday afternoon.
David Ritter, CEO at Greenpeace Australia Pacific, said: “Less than a day after two Greenpeace Australia Pacific activists were arrested for their peaceful protest at Woodside’s Scarborough gas platform to save Scott Reef, we are here again with another message to Woodside: half a million of us do not want your dirty gas at Scott Reef.
“Community pressure on Woodside is rising. Today we are here to show Woodside that they can’t ignore half a million people who want Scott Reef protected, not turned into an industrialised gas zone.
“Woodside can’t be trusted with our oceans. Woodside’s plans to drill up to 57 toxic wells at Scott Reef, Australia’s largest oceanic reef, putting endangered pygmy blue whales at risk, and jeopardising a nesting ground for unique green sea turtles.
“We Australians love our oceans and this is an opportunity for our governments to do the right thing, to reject Woodside’s reckless drilling plans, and save Scott Reef.”

Greenpeace Australia Pacific activists in police custody after two-day protest against Woodside’s Browse gas project at Scott Reef
PERTH, Sunday 18 October 2026 — Two Greenpeace Australia Pacific activists are in police custody after occupying a gas platform at Woodside’s Scarborough gas project, in peaceful protest of the fossil fuel corporation’s plans to drill for oil and gas at Scott Reef.
NEW footage and photos of the peaceful protest available here and on Instagram
The activists used specialised climbing equipment to scale and attach themselves to a Floating Production Unit (FPU), a key piece of gas processing infrastructure at the Scarborough gas field over 200km off the coast of Exmouth, at around 05:45am AWST on Saturday and proceeded to occupy the platform for two days, displaying banners reading “Stop Woodside’s Dirty Gas. Save Scott Reef.”
Special police forces landed a helicopter on the FPU at around 11:30am AWST. The activists safely removed themselves from their equipment before being taken into police custody around 1:00pm AWST. At the time of writing, no charges have been laid.
David Ritter, CEO at Greenpeace Australia Pacific, said: “It takes guts and conviction to do what our activists have done, peacefully protesting Woodside’s reckless gas plans at Scott Reef.
“Woodside’s plans to drill up to 57 toxic wells at Scott Reef are outrageous. If allowed to go ahead Woodside would turn Scott Reef, Australia’s largest oceanic reef, home to nesting green sea turtles and elusive pygmy blue whales, into an industrial gas zone. Around half a million people have called on our governments to stop Woodside and to save Scott Reef.
“Our activists are highly trained and experienced in these activities. West Australia has a proud history of peaceful, democratic protest at sea, to protect our oceans from environmental threats. From whaling in Albany in the seventies, to Woodside’s threat to Scott Reef today, there’s more than fifty years of history, of Greenpeace taking action off WA’s coast to protect the places we love.
“Peaceful protest has long been part of what has given us so many of the things that are great about Australia and is part of the fabric of our democracy and our national identity.”
“The right to peaceful protest is fundamental to a healthy democracy. From Australia to the Arctic and the Amazon, Greenpeace has been peacefully protesting for more than 50 years to expose the biggest environmental threats around the world. We will not be silenced by corporations like Woodside who actively try to stop everyday people from speaking out against their reckless plans.
“Woodside’s reckless proposal to drill at Scott Reef is an unacceptable risk to Scott Reef and to the climate, which our government should emphatically reject.”
Speaking from the Rainbow Warrior, Captain of the Rainbow Warrior Hettie Geenen, said:
“It felt powerful watching from the Rainbow Warrior as these brave activists scaled Woodside’s enormous and imposing gas infrastructure, which has no place at Scott Reef. We are all out here because we feel an urge to act, in the face of Woodside’s grave threat to Scott Reef and to our climate. Now we ask for the Australian government to act too, and reject Woodside’s reckless Browse project.
“Just before this peaceful protest, the Rainbow Warrior sailed to Scott Reef, where our whole crew got to witness the magic of an untouched, healthy reef ecosystem full of marine life. It was my second time visiting Scott Reef with the Rainbow Warrior. When you see Scott Reef up close and witness its magic first hand, it is impossible not to feel driven to try and protect it.”
The activists sailed to Scarborough on the Rainbow Warrior, Greenpeace’s flagship vessel, which is in the region campaigning to protect Australia’s oceans, including Scott Reef.
