Remarkably, Sri Lanka has a life expectancy that's similar to the USA (shy by a year and a half) with a staggering 88% less resource use and 94% less emissions on a per capita basis.
These metrics are consumption-based:

Raw material consumption:
USA: 32.36 tons per person
Sri Lanka: 3.88 tons per person

CO2 emissions:
USA: 18.35 tons per person
Sri Lanka: 1.03 tons per person
By the way, Sri Lanka has a free, universal public healthcare system.
This thread continued: "To put this in perspective, if the world were to converge to Sri Lanka, global average life expectancy would increase by 4.5 years, while global resource use would fall by 80%, and global emissions would fall by 70%." See below for more:
The purpose of this thread was to highlight what the people of Sri Lanka have managed to achieve in terms of human development, against extraordinary odds. Note: As of this year, life expectancy in Sri Lanka is higher than it is in the USA.
Scholars of international development have remarked on Sri Lanka's performance for decades, beginning with Amartya Sen in the 1980s: pubmed.ncbi.nlm.nih.gov/12339005/
The tweet above was meant to illustrate this with reference to the global scale. Right-wing accounts used screenshots, out of context, to imply, without evidence, that Sri Lanka - which is presently suffering a brutal crisis - is some kind of degrowth ideal. This is absurd.
The thread does not state this, I don't believe this, and it's nowhere evident in my work. I deleted the tweet to prevent its misuse until I could write more. But of course this didn't dissuade these accounts, which are clearly uninterested in the scientific scholarship.
I have always been clear: no country meets human needs within planetary boundaries - including Sri Lanka. The existing economic system fails to achieve this basic goal. Our published research has demonstrated this several times. nature.com/articles/s4189…
So, we need to change the economic system. The present crisis in Sri Lanka urgently underscores the need for this - at the national level but also at the global level:
Sri Lanka's development has been impeded by an export dependency imposed by colonialism, several decades of neoliberal structural adjustment programmes imposed by the IMF and, tipping the scales into the present crisis, an authoritarian right-wing regime. theconversation.com/whats-happenin…
Furthermore, as a result of structural adjustment and other pressures imposed by the institutions that govern international finance and trade, Sri Lanka - like other global South countries - is subject to drain through unequal exchange: sciencedirect.com/science/articl…
I have been at pains to point out that Sri Lanka, and other nations like it, need to increase their use of energy and resources in order to achieve development objectives. Doing this requires breaking free from domination by foreign capital. newint.org/features/2021/…
The impulse among tweeters in the imperialist states to point mockingly to global South countries as "basket-cases" is really horrific. The people of Sri Lanka deserve our support and solidarity in calling for - and organizing to achieve - a more just economic system.
And for those who care to read about what degrowth and post-growth scholarship actually argues needs to happen in rich countries, here is one place to start (and here is a free PDF: jasonhickel.org/s/Hickel-et-al…): nature.com/articles/s4156…

Let me tell you something about Cuba.

US officials are constantly saying "socialism in Cuba is a failure". But in fact Cuba's achievements with socialism are extremely impressive:

First, remember that the US imposed sanctions and blockade on Cuba *immediately* after the revolution, with the explicit objective of destroying the economy, preventing development, and immiserating the people.

And yet Cuba nonetheless managed to achieve some of the very best social outcomes in the developing world, rivalling even high-income countries in the imperial core.

The pressure on Cuba intensified dramatically after the fall of the USSR, which was a key trading partner. The blockade bit harder and Cuba was forced into a severe economic contraction known as the "special period".

And yet, even while GDP and consumption were declining or stagnating during this period, Cuba not only *accelerated* its progress on life expectancy, it caught up to and surpassed the United States in 2003, despite having 80% less GDP/capita.

Cuba also used industrial policy to develop one of the most advanced biotech industries in the world, escaping dependence on Western monopolies, and providing life-saving assistance to other countries in the global South.

How? Because of socialism! Socialism enabled Cubans to organize production and resources around what is most important for human needs, rather than what is most profitable to capital. This made them *extremely* efficient at converting limited resources into human well-being, despite the blockade.

Cuba's food system is a great example of this. Cuba developed a public food system that guarantees everyone has access to basic nutritional requirements. Thanks to this system, Cuba has one of the lowest death rates due to malnutrition in the world, lower even than in many high-income countries, such as the United States, Denmark and France.

Anyone who visits Cuba immediately notices that it is totally unlike any other developing country. You just don't see people homeless and starving and begging on the street. People certainly aren't rich, but nobody lives in misery. People have *dignity*, they have freedom, they have sovereignty.

I always find myself thinking, what could Cuba be like if it was not for the US blockade? What if it had been allowed to develop freely? It is not difficult to imagine the heights of human progress the Cubans could have achieved.

The US blockade is tightening, strangling the country of basics, in order to destroy that potential. To destroy that dignity and sovereignty. They are doing it not because socialism "failed", but because it has succeeded, and that reality cannot be accepted.

New research highlights from 2025! 

This thread covers some of our latest work on capitalism, imperialism, post-growth and ecosocialist futures. It's all open access, and free PDFs are available via the link at the end of the thread. 🧵
1) We wrote this review of exciting recent developments in post-growth science, in The Lancet Planetary Health. It's your one-stop introduction to all the key questions, debates, and empirical evidence:

thelancet.com/journals/lanpl…
2) We assessed public backing for eco-socialist transformation in the UK and US, and found it enjoys strong majority support in both countries: 72% in the US and 82% in the UK.  We also tested how different labels affect people's support:

How popular are post-capitalist/socialist ideas and policies?

Here's a list of studies and surveys with some striking results...
1. A survey shows that a majority of people around the world (56%) agree with the statement “Capitalism does more harm than good”. In France it is 69%, in India it is 74%.

Source: Edelman Trust Barometer, 2020. edelman.com/news-awards/20…
2. A study found that in 28 of 34 countries, a majority of respondents hold anti-capitalist positions.

Who is driving climate breakdown? Buckle up for some striking data... 🧵

1. First, global North countries are responsible for 86% of cumulative emissions in excess of the safe planetary boundary.

China is responsible for 1%. The rest of the South and peripheral Europe is responsible for 13%.

These results arise from taking the safe carbon budget and dividing into national "fair shares" on a per-capita basis, and then assessing national emissions against national fair-shares.Image
2. This chart uses the same data.

The global South *as a group* is actually still within its fair share of the planetary boundary (350ppm), since the few "overshooting" countries are compensated for by "undershooting" countries.

By contrast, the global North has burned through not only its fair-share of the planetary boundary, but also its fair share of the 1.5C budget AND its 2C budget.Image
3. Here's the same data at the country level. The red countries are in overshoot, the green countries are still within their fair-shares.

Btw, all of this data is available here, you can check the stats for your own country: globalinequality.org/responsibility…Image

I was honoured to write this for @tri_continental Pan Africa:

"One of the most damaging myths about the ecological crisis is that humans as such are responsible for it. In reality it's caused almost entirely by the states and firms of the imperial core." thetricontinental.org/pan-africa/new…
@tri_continental Because everyone always wonders about the China data, yes, as of 2019 (the final year of data in our analysis), China was responsible for only 1% of global emissions in excess of the planetary boundary. globalinequality.org/responsibility…Image
@tri_continental Curious users can check out the data for China and any other country they want using the interactive tools here: goodlife.leeds.ac.uk/related-resear…

About Spain's tourism problem... it seems intractable but the solutions are actually quite straightforward.

First, we need to recognize that tourism is not a good allocation of real resources and labour. It means producing goods and services that do not themselves directly benefit the local population. In fact, they are actively harmful to locals... gobbling up public space, destroying neighbourhoods, driving housing prices up, worsening climate change, etc.

It is much more rational and beneficial to allocate all this labour toward creating things that people actually need, like public services, affordable housing, renewable energy, and so on.

So, why do tourism at all? Two main reasons.

One reason is to get foreign currency. In this sense, tourism is basically an export (but where the export factories are plunked disastrously right into the middle of your historic downtowns). Why do exports? To pay for imports.

The solution here is simple: reduce unnecessary imports. Reduce luxury goods imports (these only benefit the rich), reduce car/SUV imports (build up your public transit system instead), etc. There are many options here. This reduces pressure for obtaining foreign currency.

A second reason to do tourism is to create jobs. This one seems like a strong argument but in fact it's not.

The obvious solution here is to implement a public job guarantee. Not only does this solve unemployment (a major problem in Spain), it mobilizes labour around socially and ecologically useful things that benefit society, rather than allocating labour to useless things like serving tourists.

In other words, there are simple alternatives to the two main reasons people cite for needing tourism. Any political party that realises this can ride the current wave of popular discontent and translate that energy into real, practical social improvements.

This is not to say that tourism should be abolished, far from it. But it's clear to everyone that extreme dependency on tourism is socially and ecologically destructive and it has to stop.
And for anyone wondering how to go about the practical business of actually scaling down the tourism industry, the answer is the same as for reducing any damaging industry (eg, fossil fuels, luxury goods, SUVs, etc): credit guidance! jasonhickel.org/blog/2024/8/20…
And for the avoidance of all doubt, tourism is an absolute, unmitigated climate catastrophe: nature.com/articles/s4155…
