What does it mean: 50% carbon dioxide byproduct, Stamets

According to Stamets 50% of the carbon base of substrate is converted to Co2.
However, I am not sure, what this means exactly?
Does this mean that 50% of dried substrate weight is converted to Co2?
In which phase does most of this conversion occur?
How much co2 is produced per kg of dried wood pellets until full colonization?
What does "carbon base" mean in this context? The carbon molecules in the substrate? What is the carbon weight percentage of wood pallets for example? Is it about 50%? So 25% of dried wood substrate would be released as co2?
I am ultimately trying to figure out how much of a health hazard it would be to have 50-100 3 liter bags incubating in my flat, without special ventilation. I will have ventilation for my fruiting chamber , of course.

Fungi are decomposers. They turn dead organic material into their own living organic material.
CO2 is produced as a result of mitochondria (the powerhouse of the cell!) within the cells producing ATP (mitochondria is the house, ATP is the power).
O2 comes from the air, carbon comes from the organic material. The chemical reactions generate heat and CO2.
As far as percentages, that sounds about right, roughly half of woody plant matter is carbon, and if mushrooms convert 50% of that into CO2, you're gonna get a bunch of CO2 being generated.
As far as safety, you likely produce more CO2 than your mushrooms do on a given day. Keep in mind that the CO2 generated by your mushrooms is over a few weeks. Passive ventilation under doors, etc. is usually more than enough. I would imagine the spores would cause more respiratory issues before you'd see issues due to hypoxia. But if you're worried, open a window for a few minutes a day.

Thanks for the explanation. But what if I have say 50kg substrate colonizing per month? Will that still be negligable?
I would assume, that colonization produces less Co2 than fruiting (though I don't know). But let's say its 50/50.
So over a month that would be 50*25%/2 = 2.25kg Co2. Apparently a person breathes out about 1kg Co2 per day.
So accoding to this calculation, the Co2 produced by mushrooms, even if you have tons of bags incubating, would be really quite ngligable, which is good news.
I ask, because I saw a video on the youtube channel what the fungus, where they showed their incubation chamber had over 7000ppm of Co2. I wonder how that happened?

Well, I assume that was intentional. Some species of mushroom won't grow right if the concentration of CO2 is too low. But that's like, gourmet mushrooms, I don't think that cubensis are that sensitive.
But yeah, your math sounds right, it will produce quite a lot of CO2, but not enough to suffocate you or anything (besides, unlike CO, you'll know for a fact if the CO2 concentrations are too high).
