Eco-Purists were what these crazies called themselves, and the name stuck like how Nazis are applied to anything fascist.
The thing was, the various nations of the planet were going to use many of the technologies that would later be put into the arcologies into a climate restoration network.
However, like the Black Hand before WW1, they would rather have things get to shit than being better...
They still sorta sound like the Saints from Prince Roger/Empire of Man
Aside from being extremely Anti-Pollution, the Saints decided that people shouldn't have terraformed other planets and made them even take out the plants & animals they brought with them to those planets and since they don't like pollution via machinery, they MADE THEM DO IT BY HAND
And because even things like feces contain Earth DNA, they decided to minimize their rations while making them do it
In a way, their "religion" was based around Humanity's "Original Sin" of Causing Pollution and making the majority of the populace repent. Whilst the "archons" and their families are permitted to "repent less" and live in luxury.
Sorta like an Eco-Terrorist version of a Corrupt Communist State
