When G20 finance ministers gather in Rio de Janeiro this week, Brazil and France have a chance to put these powerful countries on track to deliver a global wealth tax that could raise over $680 billion per year in the fight to tackle poverty and the climate crisis. Both countries have been vocal supporters of taxing the super-rich to fund international development and climate action.
In April, finance ministers Fernando Haddad (Brazil) and Bruno Le Maire (France) announced their intent to tax the wealth of billionaires by at least two percent annually, prompting ministers from Germany, South Africa and Spain to back the proposal. As the current host of the G20, Brazil commissioned an investigation into the feasibility of this global wealth tax – and the results were published by French economist Gabriel Zucman in June, generating further momentum in efforts to fill the funding gap for climate and development.
Zucman’s findings show that a global wealth tax on the super-rich – billionaires and people with assets worth more than $100 million – could be enforced successfully even if all countries did not adopt it. It is also a popular measure: more than two-thirds of people across seventeen G20 countries show support for making the super-rich pay higher taxes as a means of funding major improvements to our economy and lifestyles.
This isn’t surprising. Ensuring that billionaires are properly taxed could deliver significant, tangible benefits in people’s lives and go some way to addressing the systemic injustices and inequality reflected by the climate crisis and poverty.
The world needs a new global deal on climate and development finance
An ambitious global wealth tax, together with higher and permanent tax on oil corporations and extraction, would provide hundreds of billions of dollars/euros each year to properly fund scaling up renewable energy, rolling out heat pumps and insulation programmes to lower the cost of heating or cooling our homes, new public transport links, future-proof jobs and much more – helping communities to thrive.
It would also end more than a decade of broken promises by G20 states, ensuring that some of the world’s wealthiest countries have enough money in their national coffers to provide adequate finance to pay for those suffering the consequences of climate impacts now. Helping the poorest communities prepare for unnatural disasters like increased wildfires, flooding and sea level rise, and ensuring people can rebuild their homes, infrastructure and places of work when preventative measures are not an option.
Power to communities
A global wealth tax is a moral imperative. By implementing a fairer system of taxation, the G20 could accelerate a just transition to a low-carbon economy, cutting dangerous carbon emissions and boosting living standards and energy access at great scale, while also tackling deep-rooted injustice. Delivering finance for community-oriented renewable energy projects across Latin America, Africa, Asia and the Pacific would put power back in the hands of communities that continue to suffer from the violent legacy of colonialism and extractive profiteering.
For this to be achieved France, and other wealthy nations in the G20 like Germany and the UK, must be willing to make concessions and assume historical responsibility for exploiting fossil fuel extraction in the economically poorer countries whose citizens are experiencing the worst consequences of the climate crisis. The emerging French government must deliver concrete plans to redirect its fortune and tax its billionaires towards a renewable energy-powered planet.

It is incumbent on both Brazil and France to seize the opportunity presented by growing support to deliver a global wealth tax at the meeting of powerful finance ministers this week. Both countries must do everything they can to build trust and political will around the crucial proposal. But this will be a challenge if they undermine their stance on the international stage with contrasting domestic policy, something both governments are guilty of.
Brazil has been pushing for new oil projects, including in the Amazon and is gearing up to become the fourth-largest oil producer in the world. France, despite being fined by the European Commission, is still not on track to meet its domestic renewable energy targets and announced in February a two billion-euro cut to the budget allocated for environmental and energy transition programmes. It is high time for both countries to stop the smoke and mirrors approach to international diplomacy, by aligning their commitments at national and international levels.
Leaders’ summit
This week, ministers Haddad and Le Maire have a responsibility to rally their G20 counterparts around the wealth tax proposal and send a strong and unified signal to heads of state and governments to take concrete action that delivers a global wealth tax on billionaires when they meet in November.
The stakes are high. The vast scale of global inequality means that nearly one in eleven people around the world live below the poverty line according the World Bank. In addition, this is set to be yet another record-breaking year for climate impacts, in a critical decade to prevent global heating from tipping over the 1.5°C threshold – a limit beyond which the ability of impacted communities to survive and thrive will be put at intolerable risk. We need to see vast quantities of finance mobilised to scale up renewable energy at the speed needed, and billionaires and multi-millionaires need to be forced to pay up.
We’re all rooting for this one to work – it can take us a long way.

Greenpeace organisations to appeal USD $345 million court judgment in Energy Transfer’s intimidation lawsuit
SYDNEY, Saturday 28 February 2026 — Greenpeace International and Greenpeace organisations in the US announce they will seek a new trial and, if necessary, appeal the decision with the North Dakota Supreme Court following a North Dakota District Court judgment today awarding Energy Transfer (ET) USD $345 million.
ET’s SLAPP suit remains a blatant attempt to silence free speech, erase Indigenous leadership of the Standing Rock movement, and punish solidarity with peaceful resistance to the Dakota Access Pipeline. Greenpeace International will also continue to seek damages for ET’s bullying lawsuits under EU anti-SLAPP legislation in the Netherlands.
Mads Christensen, Greenpeace International Executive Director said: “Energy Transfer’s attempts to silence us are failing. Greenpeace International will continue to resist intimidation tactics. We will not be silenced. We will only get louder, joining our voices to those of our allies all around the world against the corporate polluters and billionaire oligarchs who prioritise profits over people and the planet.
“With hard-won freedoms under threat and the climate crisis accelerating, the stakes of this legal fight couldn’t be higher. Through appeals in the US and Greenpeace International’s groundbreaking anti-SLAPP case in the Netherlands, we are exploring every option to hold Energy Transfer accountable for multiple abusive lawsuits and show all power-hungry bullies that their attacks will only result in a stronger people-powered movement.”
The Court’s final judgment today rejects some of the jury verdict delivered in March 2025, but still awards hundreds of millions of dollars to ET without a sound basis in law. The Greenpeace defendants will continue to press their arguments that the US Constitution does not allow liability here, that ET did not present evidence to support its claims, that the Court admitted inflammatory and irrelevant evidence at trial and excluded other evidence supporting the defense, and that the jury pool in Mandan could not be impartial.[1][2]
ET’s back-to-back lawsuits against Greenpeace International and the US organisations Greenpeace USA (Greenpeace Inc.) and Greenpeace Fund are clear-cut examples of SLAPPs — lawsuits attempting to bury nonprofits and activists in legal fees, push them towards bankruptcy and ultimately silence dissent.[3] Greenpeace International, which is based in the Netherlands, is pursuing justice in Europe, with a suit against ET under Dutch law and the European Union’s new anti-SLAPP directive, a landmark test of the new legislation which could help set a powerful precedent against corporate bullying.[4]
Kate Smolski, Program Director at Greenpeace Australia Pacific, said: “This is part of a worrying trend globally: fossil fuel corporations are increasingly using litigation to attack and silence ordinary people and groups using the law to challenge their polluting operations — and we’re not immune to these tactics here in Australia.
“Rulings like this have a chilling effect on democracy and public interest litigation — we must unite against these silencing tactics as bad for Australians and bad for our democracy. Our movement is stronger than any corporate bully, and grows even stronger when under attack.”
Energy Transfer’s SLAPPs are part of a wave of abusive lawsuits filed by Big Oil companies like Shell, Total, and ENI against Greenpeace entities in recent years.[3] A couple of these cases have been successfully stopped in their tracks. This includes Greenpeace France successfully defeating TotalEnergies’ SLAPP on 28 March 2024, and Greenpeace UK and Greenpeace International forcing Shell to back down from its SLAPP on 10 December 2024.

Notes:
[1] The judgment entered by North Dakota District Court Judge Gion follows a jury verdict finding Greenpeace entities liable for more than US$660 million on March 19, 2025. Judge Gion subsequently threw out several items from the jury’s verdict, reducing the total damages to approximately US$345 million.

[3] Energy Transfer’s first lawsuit was filed in federal court in 2017 under the RICO Act – the Racketeer Influenced and Corrupt Organizations Act, a US federal statute designed to prosecute mob activity. The case was dismissed in 2019, with the judge stating the evidence fell “far short” of what was needed to establish a RICO enterprise. The federal court did not decide on Energy Transfer’s claims based on state law, so Energy Transfer promptly filed a new case in a North Dakota state court with these and other state law claims.
[4] Greenpeace International sent a Notice of Liability to Energy Transfer on 23 July 2024, informing the pipeline giant of Greenpeace International’s intention to bring an anti-SLAPP lawsuit against the company in a Dutch Court. After Energy Transfer declined to accept liability on multiple occasions (September 2024, December 2024), Greenpeace International initiated the first test of the European Union’s anti-SLAPP Directive on 11 February 2025 by filing a lawsuit in Dutch court against Energy Transfer. The case was officially registered in the docket of the Court of Amsterdam on 2 July, 2025. Greenpeace International seeks to recover all damages and costs it has suffered as a result of Energy Transfers’s back-to-back, abusive lawsuits demanding hundreds of millions of dollars from Greenpeace International and the Greenpeace organisations in the US. The next hearing in the Court of Amsterdam is scheduled for 16 April, 2026.

The Trump administration’s relentless rollback of public health and environmental protections has allowed widespread toxic exposures to flourish, warn experts who helped implement safeguards now under assault.
In a new report that outlines a dozen high-risk pollutants given new life thanks to weakened, delayed or rescinded regulations, the Environmental Protection Network, a nonprofit, nonpartisan group of hundreds of former Environmental Protection Agency staff, warns that the EPA under President Donald Trump has abandoned the agency’s core mission of protecting people and the environment from preventable toxic exposures.
