Six figures to understand carbon inequality from the World Inequality Report 2022.
THREAD/
1/ Close to half of all emissions are due to one tenth of the global population, and just one hundredth of the world population (77 million individuals) emits about 50% more than the entire bottom half of the population (3.8 billion individuals).
2/ The bottom half of the global population contributed only 16% of the growth in emissions observed since 1990, while the top 1% (77 million individuals) was responsible for 21% of emissions growth.
3/ In the 1990, carbon inequality was a matter of inequality between countries. Today, carbon inequality is rather one of classes, that is inequality within countries.
4/ This graph shows where emitters are.
5/ Cutting emissions is not an everybody-is-in-the-same-boat mission. In France, for example, the bottom 50% poorest must only reduce their emissions by 3%, while that cut averages 61% for the top 10% richest individuals.
6/ Degrowth for the rich, green growth for the poor.

Karma moment in science. Two weeks ago, @IvanVSavin & @ProfJeroenBergh published a (flawed) review of the degrowth literature arguing that there were « very few studies using formal modelling ». This week, Lauer et al. published a study showing that this is wrong. 🧵
Systematically reviewing the literature from 2000 to 2023, Arthur Lauer and his colleagues identify 75 modelling studies.
Savin and van den Bergh (2024) argue that « the fraction of studies undertaking modelling or data analysis fluctuates in the range of 0-15% over tiem shows no clear trend » (p.3). Wrong again.
Today is Black Friday, a nonsensical ritual invented by for-profit businesses for the sole sake of moneymaking. By shopping today, you are willingly enriching a small class of business-owning super-polluters who bath in ecosystem-killing profits.
The top 10% richest humans own 76% of world wealth and generate 50% of all carbon emissions. The footprint of the world top 1% equals the one of the poorest 66% of humanity.
We are told that consuming forever more is part of human nature. Bullshit. The seemingly inescapable rat-race for positional prestige is constructed by an army of influencers, growth hackers, and ads designers. Read it again: the destruction of life on Earth is designed.
Of course that's your contention. You're an economist who just heard about degrowth. You just got finished reading some quick-and-dirty critique – the latest piece in The Economist probably – and you’re convinced that degrowth is unnecessary because we can green growth.
You’re gonna be convinced of that ‘til next month when you read "Decoupling Debunked", then you’re going to admit that decoupling has never happened in the past but you’ll say that it could sure happen in the future.
That’s going to last until next year when you’ll be regurgitating Andrew McAfee, Sam Fankhauser, or Alessio Terzi about how price signals and technological progress can solve any environmental issue.
Summary of my talk at the #BeyondGrowth conference on the impossibility of green growth and the necessity of degrowth. 🧵
There is a rumour that is picking up speed in the media, affirming that it is possible to both produce more while polluting less. Some people call it “green growth.”
This rumour is not only a rumour, it is also a belief deeply embedded within our current environmental strategies. Problem: The idea of an economic growth fully decoupled from nature is scientifically baseless and it is distracting us from more effective transition strategies.
