If you think inequality is only a matter of income, think again – and check this study on energy inequality by @yl_oswald, @dr_anneowen, and @JKSteinberger.

1/ The richer a country, the bigger its energy footprint.
2/ Failure in economic inclusion causes exclusion from energy provision. Also: when expenditure is highly unequal in a country, the corresponding inequality in energy footprints will tend to be even larger.
3/ Consumption categories that feature higher energy intensities and higher elasticities, such as vehicle fuel, concentrate energy use among high-income individuals.
4/ What should be degrown? Answer: what’s in the red box, namely high-intensity goods and services only consumed by the richest.
5/ There are ~550 million people in each decile, so roughly the equivalent of today’s European Union. The top 10% consume ~39% of total final energy (nearly equivalent to the consumption of the bottom 80%), whereas the lowest 10% consume almost 20 times less, ~2%.
6/ The top 10% uses 75% for air transport. Said differently: flying is a luxury only used by the rich.
7/ The energy footprints of the richest reach 200-300 GJ yr. (...) On the other hand, 77% of people consume less than 30Gjyr and 38% consume less than 10Gjyr – this lower end is almost certainly insufficient for a decent quality of life.
8/ Economic growth aggravates inequality.
9/ 31% of the energy increase can be attributed to vehicle fuel alone, another 33% to heat and electricity and another 12% together to other transport and the education and finance and other luxury category. Other subsistence such as food and wearables, together, contribute 7%.
10/ Take-home message: We won’t solve the climate crisis without addressing national and international inequality.
Six figures to understand carbon inequality from the World Inequality Report 2022.

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.
Is decoupling likely to happen? To find out, here is a thread summary of my third and final lecture for The Norwegian Society for the Conservation of Nature.
(Spoiler alert: the answer is no).

1/ The first limit to greening growth has to do with declining rates of Energy Returns on Energy Invested (EROI), meaning that it takes more and more energy to obtain energy.
2/ And for the economists out there who will argue that the energy sector is not that important because it’s only a small part of GDP, read this paper.
Here is a summary of my second lecture for The Norwegian Society for the Conservation of Nature on the topic of green growth. Question of the day: Is decoupling happening?
THREAD
The best way to answer this question is to read the systematic review of the literature conducted by Helmut Haberl and fifteen colleagues in 2020.
The first finding of that review is that most studies focus on greenhouse gas emissions and energy use, leaving out all other environmental pressures. Also: only 8% of all decoupling studies use consumption-based indicators.
