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.

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.

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.

Le rapport de @pisaniferry pour @Strategie_Gouv est criblé d'erreurs sur la décroissance. 🧵 Sobriété = consommer moins. Croissance = produire & consommer plus. J'ai du mal à voir en quoi consommer moins nous mènera à consommer plus...

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.”

Degrowth as a transition from a growth economy to a post-growth economy. An increase in production and consumption to grow profit for private owners by privatizing the benefits and socializing the losses in the spirit of enhancing well-being for the selected few.

Green growth is macroeconomic greenwashing. A summary of my response to @paulkrugman after his article on green growth in the @nytimes. 🧵 Arguing that economic growth can be greened by showing evidence of one single impact going down is like bragging about being healthy by showing that one of your arms has lost weight. Sustainability requires a reduction of many environmental pressures.

The topic of #degrowth has never been more popular. Here is a selection of recent articles published in mainstream media.

THREAD "But what if growth is at best doing little to fix the world’s problems, and at worst fostering the destruction of the planet and jeopardizing its future?"

7 concepts from Herman Daly that will change your vision of economics. 1/ The ENVIRONMENTALLY EXTENDED INPUT-OUTPUT TABLE: bringing purely economic interactions, purely environmental interactions, and interactions between the economy and the environment into one comprehensive framework.

New study about @SDGoals in EU member states shows lack of progress concerning environmental targets. This study splits SDG indicators into two categories: "socioeconomic development" and "environmental sustainability"

What @paulkrugman says about green growth and degrowth is not only wrong - it is dangerous. Here is why. Krugman argues that "despite lots of economic growth, British CO2 per capita is back down to the levels of the 50s — the *1850s*. Emissions reflect choices, not the level of GDP."

We need to seriously consider the ecological impacts of consumption in high income nations. In this report, the Spanish Ministry of Consumer Affairs conducts a thorough study of the Spanish national economy and its biophysical metabolism. 🧵 It’s like a life-cycle assessment with 16 indicators of environmental pressure but for the Spanish economy as a whole.

If you think commercial aviation is a disaster for the climate, wait to hear numbers about the impact of private jets.

🧵 Even though they're rather small (2% of the footprint of aviation), private jet emissions are growing even faster than commercial emissions.

Final episode of [ECO]NOMICS: “System change” by @JulietSchor at @INETeconomics. Countries who manage to reduce emissions happen to be countries who also reduce working hours.

11 things you should know about the aviation's role in the climate crisis, based on @StayGroundedNet latest report "Common Destination." 🧵 Aviation is a major source of emissions.

For the past month, I've been posting quotes from the latest IPCC report. Here they are. 🧵

Here is a thread to summarise the second episode of [ECO]NOMICS “Political Economy of Climate Disruption” by @JulietSchor at @INETeconomics. Not many economists study the environment, and the people who do are often 'externalised' from the core of the discipline.
