On 4 June 2026, the World Inequality Lab published the Global Justice Report, subtitled A Plan for Equality and Prosperity Within Planetary Boundaries. Forty-five contributors, working on databases built by more than two hundred researchers, produced the first fully quantified transition path from 2026 to 2100 that models redistribution, financial architecture reform, energy transformation and consumption change together rather than separately. Its headline result: global warming of 1.8 degrees by 2100 under what it calls sustainable convergence, against 4.8 degrees under persistent inequality and current policies. The report's coordinators include Thomas Piketty. Its institutional machinery includes a global wealth tax, a Global Justice Fund and a World Sovereign Fund. Search either the full report or its summary for the word Ireland. Zero results.

That absence is not a complaint. From the Paris School of Economics, Ireland is a rounding error: 0.066% of world population, a small rich country inside the European aggregate. The absence is an opportunity, because when you run the report's levers one at a time through the Irish case, something uncomfortable emerges. Ireland is not an average rich country on any of them. On the revenue lever, the architecture lever, the sufficiency lever and the land lever, Ireland sits at or near the extreme of the distribution the report is trying to fix. A plan for the world that never says Ireland turns out to describe Ireland more precisely than it describes almost anyone else.

Readers of this site will recognise the spine. What the Finance Minister Already Knew set out the long arc of wealth concentration Piketty documents and where Ireland sits on it. The Wealth Tax Ireland Already Has set out the Zucman mechanism and the case that Ireland is uniquely placed to legislate it. Both were published on 25 May, ten days before the report. The report's contribution is the thing those pieces could not do alone: it binds the wealth argument to the climate argument quantitatively and shows that neither works without the other. This piece is about what that binding means here.

The claim that joins the threads

The report's central finding is easy to state and hard to dodge. To keep warming below 2 degrees while letting the poorer half of the world reach decent living standards, three things have to happen at once: fast decarbonisation of energy systems, sufficiency, meaning a structural reduction in working hours and material throughput with a large shift of the economy into education and health, and a drastic compression of income and wealth inequality between and within countries. Remove the third and the other two fail, financially and politically. The wealth tax pays for the transition. The compression keeps the bottom and middle of every country's distribution on side while it happens. The report prices the alternative: under persistent inequality and slow decarbonisation, 4.8 degrees by 2100.

The political mechanism behind the financing claim is the one Piketty has been pressing since the gilets jaunes. France tried to do carbon policy without distribution in 2018, a fuel tax that hit working and middle-class households harder than the rich, and the policy died on the roundabouts. "If you don't put this at the centre of your analysis and if you talk about green policies, environment, in the abstract, this is simply not going to work," he told the Guardian at the report's launch. The report gives that failure a name, classless ecology, and a price.

The quantified version runs like this. A global wealth tax rising from 0% at ten times average world wealth to 20% per year on billionaires, plus a global income tax rising to 90% at the very top, together touching about 1% of the world's population. The proceeds flow through a Global Justice Fund into country dividends conditioned on climate, education, health and inequality targets, and into a World Sovereign Fund that stabilises at about 10% of the world capital stock, a permanent public stake steering investment toward sustainable assets. Average income converges to €5,000 a month everywhere by 2100. Working hours fall from about 2,100 a year to about 1,000. The share of the world's working hours spent in education and health rises from 11% to 43%. The global bottom 50% wealth share rises from 2% to 30%; the billionaire class falls from 6.4% of world wealth to 0.05%.

One detail of the tax design deserves more attention than it has received. In the report's projections the billionaires, for all the headline rates, are not where most of the money is. Over 2026 to 2035 the group paying roughly five times more than the billionaires is the layer below them: millionaires, decamillionaires and centimillionaires. Keep that in mind when we get to who, in Ireland, the plan is actually about. It is a much larger group than eleven people.

You can argue with the targets. The authors themselves call the platform "relatively moderate, arguably too moderate", since full reparation for colonial and climate damages would cost roughly four times what their plan transfers. What you cannot do, after this report, is claim that nobody has done the arithmetic. The arithmetic now exists, in public, with replication packages. The question it puts to every rich country is the same: which side of each lever are you on?

So run the levers through Ireland.

Lever one: the revenue runs through the architecture Ireland operates

The report's revenue side assumes the world can find and tax the wealth and profits of the top 1%. The reason it cannot do so today is a small set of jurisdictions that make finding and taxing them structurally difficult. On the corporate half of that problem, Ireland is not one jurisdiction among many. By the EU Tax Observatory's accounting, roughly $1 trillion of multinational profits were shifted into low-tax jurisdictions in 2022, and Ireland and the Netherlands were the two largest destinations at over $140 billion each. In Ireland, foreign-owned firms book nearly €6 of profit for every €1 of wages they pay; for local firms the figure is about 50 cent. The earlier academic estimate by Tørsløv, Wier and Zucman put more profit shifted into Ireland than into the entire Caribbean haven system combined.

The domestic fiscal mirror of that position is by now familiar to readers of What the Surplus Hides and Cleanest and Dirtiest. Corporation tax receipts reached €32.9 billion in 2025, up 17.2% in a year, and that excludes the Apple money. The top ten corporate groups pay 57% of it. The Irish Fiscal Advisory Council put it more starkly in February: three groups alone paid 46% of the 2024 receipts, about €13 billion, with two technology firms accounting for roughly 40%. The funds sector domiciled here administers over €5.3 trillion in assets, more than sixteen times the size of the actual domestic economy. The State's own statisticians concede the distortion every July: GDP for 2024 was €562.8 billion, while modified gross national income, the series the CSO invented because GDP had stopped describing the country, was €321.1 billion. The headline measure of the Irish economy overstates the real one by about 75%.

Set the report's first lever beside those numbers and the Irish position clarifies. The Global Justice Fund's revenue model assumes the end of exactly this. Not as a moral flourish: as an accounting requirement. The report's billionaire and centimillionaire tax bases are only reachable if profits and wealth become visible where they are really earned and held, and Ireland is among the largest single reasons they currently are not.

Lever two: the State's positions are absences

A country in that position might be expected to argue its corner. What Ireland actually does is more interesting: it declines to have a position at all.

The live political vehicle for the report's architecture is the UN Framework Convention on International Tax Cooperation, the process the report names alongside the Bridgetown Initiative and the G20 work as the road to its Global Justice Fund. In December 2023, when the General Assembly voted to begin that process, the resolution passed 111 to 46. The 46 noes included every EU member state, Ireland among them; Oxfam Ireland's record of the process states it without diplomatic padding: "Ireland expressed its opposition to this process by voting against this proposal." By December 2024, when the Assembly adopted the convention's terms of reference 125 to 9, the EU bloc had softened from opposition to abstention. All 27 abstained. The 9 still voting no were led by the United States and the United Kingdom. Ireland's trajectory through the votes, no and then abstain, is the diplomatic shape of a country that knows which way history is moving and would prefer it moved slower.

On the wealth half of the architecture the silence is total. In 2024 the Brazilian G20 presidency commissioned Gabriel Zucman to design a coordinated minimum tax on billionaires, the 2% blueprint this site examined in detail in May. France, Spain and Brazil support it. The United States and Germany came out against. For this piece, searches of Government statements, Oireachtas debates and departmental releases found no stated Irish position on the proposal in either direction. Not opposition. Nothing. The parliamentary record shows the same reflex domestically: asked three times in 2025 about a net wealth tax, by deputies Boyd Barrett, Murphy and Hearne, the Minister for Finance gave the same answer each time, that the 2022 Commission on Taxation and Welfare did not recommend a standalone wealth tax and that the more productive route is to re-examine capital gains and acquisitions taxes. The Commission, for what it is worth, also said the overall yield from taxes on wealth and capital should rise materially. The first half of the recommendation is quoted in every answer. The second half does the quiet work of not appearing.

This is the pattern What the Finance Minister Already Knew documented at the level of a single politician, now visible at the level of the State. The argument is never engaged. The Donohoe review proved the political class reads Piketty; the votes and the silences prove the State understands what is being proposed. Refusal to answer is the answer.

Lever three: Ireland already built the miniature

Here is the irony that makes the Irish case more than an indictment. The most novel institution in the report, the World Sovereign Fund, a permanent public portfolio built from wealth tax proceeds and stabilised at about 10% of the world capital stock, already exists in Ireland. In miniature, and with the politics inverted.

The Future Ireland Fund receives 0.8% of GDP every year to 2035 and is projected to reach about €100 billion. The Infrastructure, Climate and Nature Fund adds €2 billion a year to 2030. Between them they held about €18 billion by February 2026, when the NTMA appointed external managers for the portfolios: Amundi, BlackRock, State Street and UBS. The transfers are real enough to show up in the public accounts; the May 2026 Exchequer returns recorded a €2.3 billion deficit driven precisely by the payments into the funds.

Structurally this is the report's instrument. A state captures a revenue windfall, reinvests it in a permanent portfolio and uses the returns to fund future public obligations. The differences are exactly where the politics live. The report's fund is capitalised by taxing the top of the wealth distribution; Ireland's is capitalised by the corporation tax windfall, which is to say by the profit-shifting distortion itself. The report's fund is governed democratically, with conditionalities on climate, education and inequality; Ireland's is governed by the NTMA and managed in part by the world's largest private asset managers, with drawdowns beginning in 2041 against ageing costs. Ireland has proven the mechanism while inverting its purpose: a sovereign fund built not from taxing concentrated wealth but from hosting it.

Which means the standard objection to the report's architecture, that no state would ever actually build such a thing, fails in Dublin first. The State built it. It simply filled it from the other side of the ledger.

Lever four: sufficiency, in the country where the satire writes itself

The report's second pillar, sufficiency, is the one most likely to be dismissed as utopian, so it is worth seeing how its components land here.

Start with the sectoral shift. The report wants the share of working hours in education and health to rise from 11% globally to 43% by 2100, and notes that Norway and Sweden already stand at 30 to 35%. Ireland's figure, from the CSO's Labour Force Survey for the first quarter of 2026, is 23%: health and social work at 13.7% of employment, education at 9.3%. On the spending side Ireland produces one of the cleanest illustrations anywhere of why the report insists every economic claim be read against an honest denominator. By Eurostat's count Ireland spends over €5,700 per inhabitant on healthcare, second in the EU only to Luxembourg. The same Eurostat tables show Ireland spending 6.6% of GDP on health and 2.8% on education, the lowest in the EU on both. Both readings are arithmetically true. The denominator is the fiction, the same €240 billion of phantom GDP that separates the Irish economy from the Irish country. A state that needed a reason to discount its own education spending as a share of national income has one ready-made; the report's whole method, monetary accounting disciplined by material accounting, is designed to take that excuse away.

Working hours: Irish workers average 1,622 hours a year against an OECD average of 1,736 and a German figure of 1,331. On the report's trajectory toward 1,000 hours by 2100, Ireland is mid-pack and drifting rather than moving. The four-day-week pilot of 2022 produced its evaluations and then nothing; there is no live legislation. Eurostat adds a detail the report would recognise instantly, since full gender equality in hours and pay is one of its named targets: the gap in weekly hours between full-time men and women in Ireland is the largest in the EU.

Then there are the data centres. At the report's launch, Piketty described the economic project of the billionaire class in one line: "Their new dream is to cover the entire planet with datacentres." He was speaking globally. There is one country in Europe where the dream is furthest advanced, and it is this one. In 2024, by the CSO's count, data centres consumed 22% of all metered electricity in the State, 6,969 gigawatt hours, more than every urban household in Ireland combined, more than urban and rural households combined. The share was 5% in 2015. EirGrid's projections put it around 30% by the early 2030s. Dublin hosts the second-largest data centre cluster in Europe, behind only London. Whatever one thinks any individual data centre is for, the aggregate is a national experiment in exactly the trajectory the report says is incompatible with a habitable planet: rising material and energy throughput, owned at the top of the wealth distribution, crowding a grid the State is simultaneously failing to decarbonise fast enough to meet its own legal budgets.

About those budgets. Ireland's first statutory carbon budget, 2021 to 2025, will be close to met on the EPA's latest projections, published on 26 May. Close to met deserves its asterisk: the Climate Change Advisory Council's review last November found the budget exceeded, and the gap between the two findings is largely a scientific revision of agricultural methane that lowered the inventory's estimate of what the national herd emits, a re-measurement, not a reduction. On the second budget no arithmetic helps. The EPA projects the 2026 to 2030 budget will be exceeded by 53 to 82 megatonnes, a margin of more than a quarter of the budget itself, with national emissions falling at most 25% by 2030 against a legislated target of 51%. The Fiscal Advisory Council and the Climate Change Advisory Council jointly priced the EU compliance exposure at €8 billion to €26 billion. The Minister responsible described that estimate as "back of the envelope stuff". The envelope, as it happens, is the State's own advisory architecture doing the arithmetic the State declines to do.

Lever five: the dead instruction

One prescription in the report fails in Ireland in a way the authors plainly never considered, and the failure is more instructive than the prescription.

The report's land lever calls for a strict deforestation ban and a gradual return of global forest cover to the 1900 level. As a global average that is an ambitious reforestation target. Apply it to Ireland and it is a dead instruction. By the end of the nineteenth century, woodland in Ireland was down to roughly 69,000 hectares, about 1% of the land area, the lowest in Europe, the bottom of a curve that had been falling for three centuries. Restoring Ireland to its 1900 baseline would mean cutting down almost everything now standing. The stripping that created that baseline was not an accident of geography. It was extraction, shipbuilding, barrel staves, charcoal, plantation clearance, conducted under the colonial administration of the same period for which the report's own accounting prices reparations at 3.2% of world GDP a year. Ireland is the one rich-world country whose ecological baseline was itself an extraction site, a fact that puts it on both sides of the report's ledger at once: a present-day beneficiary of the financial architecture the report would dismantle, and a country whose landscape still carries the damage the report says warrants repair.

The present-day numbers extend the story without improving it. Forest cover today is 11.6%, still among the lowest in the EU against an average around 38%, and the headline flatters reality twice over. Most of it is commercial Sitka spruce on clearfell rotation rather than forest in any ecological sense. Native woodland covers just under 2% of the country, and the surviving fragments of ancient woodland, the oldest of them remnants of Atlantic temperate rainforest in a country whose entire western seaboard sits inside the temperate rainforest biozone, amount to around 20,000 hectares, less than a third of one percent of the land. The State's own afforestation target is 8,000 hectares a year. Actual planting: 1,651 hectares in 2023, 1,573 in 2024, 2,829 by late 2025. A fifth to a third of target, every year, while agriculture holds at 37.9% of national emissions, the highest sectoral share in the EU by a distance.

The report assumes the rich world's land problem is protecting what it has. Ireland's land problem is that the destruction happened early enough to fall out of everyone's baseline, including, it turns out, the World Inequality Lab's.

Who the plan is about, here

Every redistribution argument eventually reaches the same question: who loses? The report answers it with unusual precision, and the answer is the reason the plan is politically alive rather than utopian.

In Europe, on the report's projections, 28% of people at least double their monetary income by 2100. The share who see any income decline is 6%, and the report locates them "essentially at the very top of each country's income distribution". Once leisure time and a habitable climate are counted, more than 99% of the world's population is better off. The honest caveat is also there: 10 to 20% of rich-country populations sit on the margin, and the cultural battle is over whether free time and habitability are worth having relative to a high-growth, high-warming alternative.

The Irish distribution gives those percentages faces. By the Central Bank's distributional wealth accounts for the final quarter of 2025, Irish households hold €1,382 billion in net wealth, of which the top 10% hold €661 billion, more than five times the entire bottom half. The CSO's own household survey adds the texture: an owner-occupier median of €391,600 against a renter median of €10,200, and one age group, the under-35s, whose wealth fell while every other cohort's rose. Oxfam's January 2026 count found 11 Irish billionaires holding a combined €46.7 billion, more than the combined wealth of 3.4 million Irish people. The carbon ledger tracks the wealth ledger: by Oxfam Ireland's analysis last October, a person in Ireland's richest 1% emits 14 times what a person in the bottom half emits, and the top 10% emit nearly as much as the entire bottom 50% combined.

Recall the design detail from earlier: the report's wealth tax draws five times more from the layer below the billionaires than from the billionaires themselves. The Irish membership of that layer is not eleven people. The CSO's threshold for entering the top 10% of households is just over €1 million in net wealth, which places roughly one Irish household in ten at or above seven figures. Above them sits the cohort Revenue's own Large Cases High Wealth Individuals Division exists to manage, defined as those with net assets over €20 million. That cohort, not the Collisons, is where the report's arithmetic and Irish politics would actually meet. A politics that frames the question as eleven billionaires is choosing an easier argument than the one on the table.

Set against that: the 89% of the world, the 94% of Europeans who come out flat or ahead in money terms before counting a single hour of reclaimed time or a single degree of avoided warming, and in Ireland specifically the half of the country holding 9.4% of the wealth, the renters at €10,200, the under-35s going backwards. The report's coalition arithmetic is not exotic. It is the same arithmetic as every functioning social settlement of the twentieth century, run forward.

The choice, priced

The report closes on a sentence built to be quoted, so here it is doing its work: "What stands in the way is not technical impossibility but political choice and the hard but crucial work of building a coalition behind it."

The value of the Global Justice Report for an Irish reader is that it converts that sentence from rhetoric into a rubric. Political choice is no longer an abstraction; it is a list, and Ireland's entries are all on the record. A no, softened to an abstention, on the UN tax process. Silence on the billionaire minimum tax. Three identical parliamentary answers declining a wealth tax the State's own commission said should at least be preceded by capital tax reform that also has not happened. A first carbon budget rescued on paper by re-measuring the herd, a second projected to be blown by up to 82 megatonnes, a compliance exposure of up to €26 billion dismissed as back-of-the-envelope. An afforestation programme running at a fifth of its own target. A sovereign wealth fund proving the report's most novel mechanism works, filled from the proceeds of the distortion rather than from the tax that would end it. A grid surrendering a rising quarter of its output to the one project Piketty names as the billionaire class's plan for the century.

None of this required the report. All of it was documented, much of it on this site, before 4 June. What the report adds is the price column: the arithmetic showing that the wealth question and the climate question are the same question, that a country answering both with silence is not abstaining but choosing, and that the choice has a temperature attached. Somewhere between 1.8 degrees and 4.8 degrees, the difference is not technology. It is the set of decisions this State is currently making by declining to make them.

One more piece of arithmetic, the one the whole report rests on without ever stating it plainly. The report's horizon is 2100, and 2100 sounds like posterity until you do the subtraction. A child sitting the Junior Cert in Ireland this month will be 89 in 2100. The 1.8 degrees or 4.8 degrees the scenarios price is not a projection for the unborn; it is the temperature of that child's old age, fixed by decisions taken while they are doing their homework. The signals of which world is currently being chosen are not subtle. In July 2024 a winter heatwave held East Antarctica 28 degrees above average for more than two weeks, in the polar dark, in the coldest place on Earth. On 6 June this year, five days before this piece was published, the Argentinian Esperanza base on the Trinity Peninsula logged 15.4 degrees, breaking the Antarctic winter record by two full degrees, around 20 degrees above seasonal norms, in the middle of a heatwave that kept daily maximums above zero for three consecutive weeks while rain fell on glaciers that should have been accumulating snow. Satellite analysis published in Nature Geoscience found vegetation cover on the Antarctic Peninsula has increased more than tenfold in four decades, and the greening is accelerating. Moss is colonising the continent that anchors the climate system while a rich European state misses its own carbon budgets and files the compliance bill under back-of-the-envelope. Anyone in this country with a child in school has skin in the difference between the report's two futures. That is what the choice is about, and it is the honest answer to why work like this gets written.

The plan never says Ireland. It never needed to. Ireland is what the plan is about.
