Very good writeup, thank you!
I stumbled over 2 things.
For my taste, "climate breakdown" is too ... climate-slang in an academic meta review on history and current state of #Degrowth research such as yours.
The climate can't break down. What can experience a breakdown are human systems, like supply chains, nation states, or civilisation itself. And their breakdown around inherent breaking points can be caused by the too rapidly changing climate and biosphere.
What made you choose the term "climate breakdown"?
The second stumble is a mostly overlooked emission factor. You do mention emissions embedded in trade as the elephant in the room. But citizens of 1 country cause emissions which then count towards the climate debt of another country when they travel, too. The book #Deutschland2050 quotes this NAUTRE paper https://www.nature.com/articles/s41558-018-0141-x (€+)

which reckons that in 2019, Germans caused 329Mt CO2 abroad. IIRC, it excluded the (aviation) CO2 from transportation TO the destination but included transport CO2 at the destination.
That was 40% or almost half the official German 2019 consumption-based emissions. But the 329Mt did not count toward the travelling Germans' climate debt. Instead, the countries where they traveled to now carry the burden of having had to import CO2-laden goods and services to accommodate the traveling Germans in 2019..
329Mt CO2... Yet no one speaks about CO2 embedded in travel.
#Climeworks promises they'll be able to store 1Mt per year by 2030, right? So it'd take 329 years just to store away the CO2 debt from the 2019 traveling Germans...
Even during the pandemic these traveling and ultimately, massmurdering CO2-idiots did not stop traveling..
Travel miles need to be rationed. And not via price, lest the decadent rich just keep killing us, but just and equal in a per capita allowance with spare miles set aside for state services.
Also of course: bearing mind the inequality of mobility and CO2 debt from transportation, one has to realize that not all of the 83 million Germans caused these 329Mt CO2 abroad in 2019 but that only ~ 40mio ever travel at all or that a whopping 30% never even fly at all...
