Today, we are close to the critical moment when conventional economic growth becomes impossible on a finite planet, constrained by two parallel factors: resource depletion and pollution. Tthe depletion of fossil fuels and other mineral commodities is placing heavy constraints on both industrial and agricultural production. We are not running out of anything yet, but the cost of extraction is increasing, just as the damage that extraction causes to the ecosystem. On the other side, pollution is appearing in more than one form. Chemical pollution is growing in terms of heavy metals, endocrine-disruptors, and other poisoning substances, while climate change can be seen as another form of pollution generated by the excess of CO2 in the atmosphere.

Voici un article véritablement fascinant sur les origines physiques de la crise au Venezuela et une explication des raisons pour lesquelles il était dans l’intérêt des États-Unis de mener une guerre économique afin de prendre le contrôle des réserves pétrolières vénézuéliennes, à un moment où la rentabilité du pétrole américain était en déclin.

Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energy-matter interactions. These constraints stem from the fact that Earth is a materially closed yet energetically open system, driven by the sustained but low power-density flux of solar radiation. This Perspective reframes sustainability within these axiomatic limits, integrating relevant timescales and orders of magnitude. We argue that fossil-fueled industrial metabolism is inherently incompatible with long-term viability, while post-fossil systems are surface-, materials-, and power-intensive. Long-term sustainability must therefore be defined not only by how much energy or material is used, but also by how it is used: favoring organic, carbon-based chemistry with limited reliance on purified metals, operating at low power density, and maintaining low throughput rates. Achieving this requires radical technological shifts toward l
The growth rate of greenhouse gas (GHG) climate forcing increased rapidly in the last 15 years to about 0.5 W/m2 per decade, as shown by the “colorful chart” for GHG climate forcing that we have been publishing for 25 years (Fig. 1).[1] The chart is not in IPCC reports, perhaps because it reveals inconvenient facts. Although growth of GHG climate forcing declined rapidly after the 1987 Montreal Protocol, other opportunities to decrease climate forcing were missed. If policymakers do not appreciate the significance of present data on changing climate forcings, we scientists must share the blame.
Politici ratelen tijdens verkiezingsbijeenkomsten of in interviews vaak over het belang van economische groei voor onze welvaartsstaat. Maar, voor wie groeit onze economie precies? Deze complexe vraag proberen Anuna De Wever en Lena Hartog te beantwoorden in hun nieuwe film ‘The Cost of Growth’.
In a selective history of the evolution of the degrowth movement, his chapter in the Routledge Handbook of Degrowth (2025) offers a collective and subjective reflection revealing tensions between academics, practitioners and activists. Its four co-authors have lived in and with these tensions, analysing practical experiences in the degrowth cooperative Cargonomia (Budapest, Hungary) and the low-tech ecosystem Can Decreix (Cerbère, France). The chapter aims to launch a formal, respectful and significant dialogue between degrowth academics and practitioners. How did an initial public perception of degrowth as activists who experiment-by-doing based in a radical epistemological critique of traditional academia evolve more and more into an academia-dominated movement? We reflect on the movement’s organisation to suggest how deeper collaborative relationships between researchers, activism and practitioners might strengthen degrowth as an academic field, enhance the credibility and robustness of grounded prefigurat
We are an international group of researchers and practitioners interested in the emerging fields of post-growth and ecological macroeconomics. Our aim is to advance economic theory, methodology and policy in order to adequately address some of the biggest challenges of our time: climate change, rising inequality, and financial instability.
Four Prime Ministers in twelve months. Social protests in the streets. Extreme parties rising in the polls. President Macron, once seen as Europe's great reformer, seems politically finished. But what if France's paralysis is not an exception - what if it shows Europe's future?
Chapter 5 in the Routledge Handbook of Degrowth (2025) sketches the French origins of, and approaches to, décroissance. In France, décroissance emerged early – as part of the long history of debates on the industrialisation of the world and its impacts, and of a shorter history of political ecology over the last half-century. Although inspired by a long genealogy questioning the Western industrial trajectory, the word décroissance really came to the fore in the French protest and intellectual scene in 2002, with a convergence between anti-development and anti-advertising movements. Even if degrowth as a slogan and as a movement only emerged recently, its origins, influences, pioneers, pillars and debates were already very strong in the 1970s. After a long hiatus in the 1980s and 1990s, the term décroissance spread spectacularly, entering the political and activist arena at the beginning of the 21st century, designating a sub-group of political ecologists committed to criticising economic development as the do
Je n’aurais jamais pensé écrire une réponse à Serge Latouche, l’un des pionniers de la décroissance.[1] Et pourtant, cela me parait nécessaire tant ses propos envers les degrowth studies sont problématiques.[2] Celui que l’on surnomme « le pape de la décroissance » n’aime pas la littérature anglophone (assez paradoxal d’ailleurs pour quelqu’un qui ne lit presque pas l’anglais). Un « recyclage médiatique » par des « universitaires opportunistes », un « vocable globish discutable » par des jeunes qui « n’ont pas la radicalité de la décroissance » et qui inventent des « monstruosité conceptuelles ». Dans son dernier texte, je suis personnellement attaqué, décrit comme un « rénovateur de la seconde génération », un économiste à la pensée étroite cherchant la célébrité en dénaturant la décroissance.
Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global
This brief introduces degrowth – intentional downscaling of the global economy to achieve ecological sustainability and social justice – for people working in environmental and social advocacy. It centers the question: “Has the economy outgrown the planet?” because global ecological limits have reshaped the conditions under which we pursue climate action, environmental justice, and many other pressing aims.
The growth in US power demand is surging to its highest rate in decades, driven first by the electrification of oil and gas production and then by the build out of data centers. While still below the 5-10% growth seen in China, the world’s first “electrostate," the US power sector is experiencing rapid structural growth. The country is delivering more than a 3.5% annual power demand growth rate for the first time in several decades, potentially positioning the US as the world’s next “electrostate,” despite the strong oil and gas focus of the Trump administration.
J’ai l’habitude de voir les écologistes et les futurologues parler des limites de la croissance (« The Limits to Growth »). Je suis moins habitué à voir des spécialistes de l’investissement mentionner des recherches liées aux limites de la croissance. C’est pourtant ce qu’a fait récemment Joachim Klement dans sa lettre d’information quotidienne. Bien entendu, quiconque écrit sur les limites de la croissance doit d’abord procéder à toutes les vérifications d’usage. En effet, la combinaison des mots « limites » et « croissance » dans le titre a suscité un grand nombre de réactions critiques, allant de la déformation pure et simple de l’ouvrage à l’incompréhension du modèle de dynamique des systèmes qui le sous-tend.
I’m used to environmentalists and futurists writing about The Limits to Growth. I’m less used to seeing investment writers mention research that’s linked to The Limits of Growth. But that’s what Joachim Klement did in his daily newsletter recently.
I’m used to environmentalists and futurists writing about The Limits to Growth. I’m less used to seeing investment writers mention research that’s linked to The Limits of Growth. But that’s what Joachim Klement did in his daily newsletter recently. Of course, anyone who writes about Limits of Growth has to do all the usual disclaimers first. This is because the combination of the words “limits” and “growth” in the title produced a lot of critical responses, on a range from straight-up hatchet jobs which misrepresented the book, to people who didn’t appear to understand the systems dynamics model that sat behind it.
Only 6.9% of the 106 billion tonnes of materials used annually by the global economy come from recycled sources—a 2.2 percentage point drop since 2015, according to a new report released today by Circle Economy in collaboration with Deloitte Global. The Circularity Gap Report 2025 (CGR®) finds that global material consumption is outpacing population growth and generating more waste than recycling systems can handle—underscoring the need for global circular economy targets, system-level transformation, and multilateral collaboration.
Before you read this, a word of caution. You may want to prepare yourself a stiff drink and sit down before you read the following. I think most people who read this will at some point in their life heard about the Club of Rome’s Limit to Growth publication from the 1970s. Back then, the Club of Rome asked the MIT to produce a series of forecasts for the world’s industrial and services output, food production, and pollution levels to the year 2100. Almost from the get-go, these forecasts were derided as scaremongering and flat out wrong. But were they really?
These are difficult times indeed, with terrible news on many fronts. What are the prospects for the degrowth1 alternative as we move through 2025? Dark times: the current context First, we need to understand what is going on around us: what is the evolving context with which degrowth has to contend, and to which it has to present a viable alternative?
💡 Is our obsession with economic growth leading us to collapse? Economist and research Gaya Herrington joins us to discuss why GDP is a flawed metric, how degrowth can lead to a thriving well-being economy, and why businesses must prioritize resilience over efficiency. Tune in for a critical conversation on reshaping our economic future.
There are increasing concerns that continued economic growth in high-income countries might not be environmentally sustainable, socially beneficial, or economically achievable. In this Review, we explore the rapidly advancing field of post-growth research, which has evolved in response to these concerns. The central idea of post-growth is to replace the goal of increasing GDP with the goal of improving human wellbeing within planetary boundaries. Key advances discussed in this Review include: the development of ecological macroeconomic models that test policies for managing without growth; understanding and reducing the growth dependencies that tie social welfare to increasing GDP in the current economy; and characterising the policies and provisioning systems that would allow resource use to be reduced while improving human wellbeing. Despite recent advances in post-growth research, important questions remain, such as the politics of transition, and transformations in the relationship between the Global Nort

Added complexity allows an economy to grow, even as resource limits are reached. But at some point, the complexity itself becomes a problem.
Literature reviews are usually quite uncontroversial. But this is not the case of “Reviewing studies of degrowth: Are claims matched by data, methods and policy analysis?”, a recent paper by Ivan Savin and Jeroen van den Bergh, two economists at the Autonomous University of Barcelona....
Some narratives in international development hold that ending poverty and achieving good lives for all will require every country to reach the levels of GDP per capita that currently characterise high-income countries. However, this would require increasing total global output and resource use several times over, dramatically exacerbating ecological breakdown. Furthermore, universal convergence along these lines is unlikely within the imperialist structure of the existing world economy. Here we demonstrate that this dilemma can be resolved with a different approach, rooted in recent needs-based analyses of poverty and development. Strategies for development should not pursue capitalist growth and increased aggregate production as such, but should rather increase the specific forms of production that are necessary to improve capabilities and meet human needs at a high standard, while ensuring universal access to key goods and services through public provisioning and decommodification. At the same time, in high

À la veille des élections, des scientifiques mènent des actions dans la capitale pour alerter sur les risques climatiques. Les rapports alarmants sur le climat se multiplient, mais le monde politique n’en tient pas suffisamment compte aux yeux des scientifiques. Pour mieux se faire entendre, des chercheurs et académiques belges et internationaux ont donc décidé, en cette veille d’élections, d’opter pour la désobéissance civile.

What's the relationship between our energy consumption, our material footprint and our economies? This is the "holy trinity" as Tim Garrett and I refer to these three components in our conversation. Tim is a Professor of Atmospheric Sciences at the University of Utah, and over two years ago, he joined me to discuss the thermodynamics of collapse, where he explained his research into the behaviour of snowflakes and how you could extrapolate the behaviour of economies and civilization using the laws of thermodynamics. He's back on the show to explain how we use our energy, the necessity of a surplus of energy and how all of this relates to a society's growth and health. In this conversation we discuss questions like: Will renewables facilitate an increased consumption of fossil fuels? Can we reduce inequality by reducing energy consumption? How can we organise a wave-like civilisation, which grows and decays within safe boundaries? Can we decline in order to recover before crashing completely?

After 50 years, there is still an ongoing debate about the Limits to Growth (LtG) study. This paper recalibrates the 2005 World3-03 model. The input parameters are changed to better match empirical data on world development. An iterative method is used to compute and optimize different parameter sets. This improved parameter set results in a World3 simulation that shows the same overshoot and collapse mode in the coming decade as the original business as usual scenario of the LtG standard run. The main effect of the recalibration update is to raise the peaks of most variables and move them a few years into the future. The parameters with the largest relative changes are those related to industrial capital lifetime, pollution transmission delay, and urban-industrial land development time.

We beginnen de sociale en ecologische crises steeds meer te voelen, en dus valt “degrowth” of ‘ontgroei’ niet langer weg te denken uit het debat. Maar helaas circuleren er hardnekkige misverstanden over die ontgroei. Hoog tijd om die definitief uit de wereld te helpen, vindt econoom Jonas Van der Slycken.
Scientists have raised concerns about whether high-income countries, with their high per-capita CO2 emissions, can decarbonise fast enough to meet their obligations under the Paris Agreement if they continue to pursue aggregate economic growth. Over the past decade, some countries have reduced their CO2 emissions while increasing their gross domestic product (absolute decoupling). Politicians and media have hailed this as green growth. In this empirical study, we aimed to assess whether these achievements are consistent with the Paris Agreement, and whether Paris-compliant decoupling is within reach.

Wat wensen ouders hun pasgeboren kind? Dat het gezond is, dat het opgroeit tot een fijne tiener en uitgroeit tot een volwassen persoon. Er zijn geen ouders bekend die verlangen dat hun kind groeit en blijft groeien, en dus steeds groter wordt. Dat lijkt eerder iets voor een sprookje of beter een griezelverhaal. En toch is dit laatste verlangen de overheersende wens als het over onze economie gaat. Die moet groeien, en blijven groeien. Een land gaat zogezegd achteruit als het bruto binnenlands product niet groeit, als we niet steeds, jaar na jaar na jaar, meer producten en diensten produceren. En terwijl we ons goed kunnen voorstellen hoe onwezenlijk het zou als een kind zou blijven groeien – het huis, de stoelen, het eten, het zou allemaal te klein of te weinig zijn – lukt dat dus niet als het over de groei van de economie gaat in het huis van de mens, onze aarde. Terwijl die ook niet groeit. Sterker nog, ons leven gedijt enkel in die dunne laag boven en net in de aardkorst, de kwetsbare zone van de biosfeer,

Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO2 emissions in the past six decades1. Large uncertainties in terrestrial carbon–climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change2. Interannual variations in the atmospheric CO2 growth rate (CGR) are dominated by land–atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon–climate interactions3–6. It is thought that variations in CGR are largely controlled by temperature7–10 but there is also evidence for a tight coupling between water availability and CGR11. Here, we use a record of global atmospheric CO2, terrestrial water storage and precipitation data to investigate changes in the interannual relationship between tropical land climate conditions and CGR under a changing climate. We find that the interannual relationship between tropical water availability and CGR became increasingly negative during 1989–2018 compared to 1960–1989

Wie vandaag vasthoudt aan de achterhaalde logica dat “groene groei” het klimaatprobleem zal oplossen, staat buiten de vakgebieden van de ecologische economie en klimaatwetenschap, schrijft onderzoeker Nick Meynen. ‘Toch nodigt VRT zulke “experts” uit. Het resultaat? Erudiet verpakte desinformatie.’

Concerns about climate change shrank across the world last year, with fewer than half of those questioned in a new survey believing it posed a “very serious threat” to their countries over the next 20 years.
conférence de Dennis Meadows, analyste des systèmes, initiateur et co-auteur du rapport Les limites de la croissance, Club de Rome, 1972 lundi 19 septembre 2022 ENS de Lyon, amphithéâtre Mérieux
Leestip van deze zomerse week: de Britse archeoloog David Wengrow bundelde, samen met de intussen overleden antropoloog David Graeber, de jongste antropologische en archeologische kennis en inzichten in Het begin van alles. Het is een vuistdik boek, dat internationaal een hype werd nog voor het verscheen. De auteurs nemen afstand van de speculatieve en deterministische geschiedenissen van de mensheid, bedacht door filosofen uit de 16de en 17de eeuw, die tot vandaag ons denken blijven bepalen.
Le rapport Meadows est le livre fondateur des actions de transition écologique. En voici un résumé destiné aux lycéens.
The 1972 book "The Limits to Growth" shared a somber message for humanity: the Earth's resources are finite and probably cannot support current rates of economic and population growth to the end of the 21st century, even with advanced technology. Although disparaged by economists at the time, it turns out that, 50 years later, the message still deserves our attention.
We need to break free from the capitalist economy. Degrowth gives us the tools to bend its bars.

Drought blighting country’s longest waterway continues as economic hub battles climate crisis
Degrowth is a radical economic theory born in the 1970s. It broadly means shrinking rather than growing economies, to use less of the world’s dwindling resources. Detractors of degrowth say economic growth has given the world everything from cancer treatments to indoor plumbing. Supporters argue that degrowth doesn’t mean “living in caves with candles” – but just living a bit more simply.
On degrowth in general
Jan Rotmans wist een halve eeuw geleden al dat er een klimaatcrisis op til was. En dat die heftig zou worden. Maar er is hoop. ‘De gedragsverandering kan heel snel gaan als het moet.’
In 1972, a book changed the world. The Club of Rome commissioned a report that shifted how we see what humans are doing to the planet. Looking back five decades later, what happened next, what did we do and not do, what did we learn, and what happens now? In The Limits to Growth, a team from MIT studied the way humans were using the resources of the earth. Using sophisticated computer modelling, the researchers developed scenarios to map out possible paths for humanity, the global economy and the impact on the planet.
Presentation of the book "Beyond the Limits," a new report to the Club of Roma edited by Ugo Bardi and Carlos Alvarez Pereira. It tells the story of the 1972 study "The Limits to Growth" and its relevance 50 years later.
Previous studies show that city metrics having to do with growth, productivity and overall energy consumption scale superlinearly, attributing this to the social nature of cities. Superlinear scaling results in crises called ‘singularities’, where population and energy demand tend to infinity in a finite amount of time, which must be avoided by ever more frequent ‘resets’ or innovations that postpone the system's collapse. Here, we place the emergence of cities and planetary civilizations in the context of major evolutionary transitions. With this perspective, we hypothesize that once a planetary civilization transitions into a state that can be described as one virtually connected global city, it will face an ‘asymptotic burnout’, an ultimate crisis where the singularity-interval time scale becomes smaller than the time scale of innovation. If a civilization develops the capability to understand its own trajectory, it will have a window of time to affect a fundamental change to prioritize long-term homeosta

It took me a while but I finally digested the 107 pages of Chapter 5: Demand, services and social aspects of mitigation in the last IPCC report on Mitigation of climate change. This chapter is worth the read if only because it’s the first one fully dedicated to demand-side strategies. What I find remarkable is its conceptual width, including a few ideas that are usually considered too radical in these kind of venues. But just like the rest of the report, it is long and – as academic writing too often is – full of abstract jargon and somnolent prose. What I want to do in this article is to explain why Chapter 5 is more radical (in the good sense of the term) that you may think.
Au début des années 1970, le club de Rome1 s’interroge sur la pérennité de la croissance dans un mode fini. Il confie une étude au Massachusetts Institute of Technology (MIT). Une équipe de recherche, emmenée par Dennis Meadows2, conçoit une modélisation du système socio-économique humain et de ses interactions avec la planète : le modèle World3. En 1972 paraît The Limits to Growth (Les limites à la croissance). Ce rapport, qui montre que la croissance a des limites, et que sa poursuite au-delà conduirait à l’effondrement du système, fait grand bruit.
Capitalism isn’t what it used to be. Since 2008, critics of the world’s dominant economic system have been lamenting its imperviousness to change. And for good reason. In earlier epochs, financial crises and pandemics wrought economic transformation. In our own, they seem to have yielded more of the same. Before the 2008 crash, global capitalism was characterized by organized labor’s weakness, rising inequality within nations, and a growth model that offset mediocre wage gains with asset-price appreciation. All of these have remained features of the world’s economic order.
Researchers must try to resolve a dispute on the best way to use and care for Earth’s resources. Fifty years ago this month, the System Dynamics group at the Massachusetts Institute of Technology in Cambridge had a stark message for the world: continued economic and population growth would deplete Earth’s resources and lead to global economic collapse by 2070. This finding was from their 200-page book The Limits to Growth, one of the first modelling studies to forecast the environmental and social impacts of industrialization.

En 1972 paraissait un rapport scientifique qui fit l’effet d’une bombe. Le rapport Meadows, intitulé « The limits to growth », annonçait pour la première fois au monde les limites physiques de la croissance économique. Sa conclusion est formelle : la persistance du modèle de société actuel et l’épuisement des ressources qui en découle conduit inévitablement à un « crash » dramatique au cours du XXIe siècle. Pourtant, 50 ans plus tard rien ne semble avoir changé. Dans le podcast Dernières Limites, la journaliste Audrey Boehly fait le point en interrogeant des experts et des scientifiques de la question. Quelle marge de manœuvre nous reste-il pour inverser la tendance ? Quel avenir est encore possible à la lumière des ressources disponibles et des enjeux écologiques à venir ? Entretien.
