i thought this was an order of magnitude problem, like when people react the same way to an epidemic that could kill a hundred thousand people or a hundred million, but it turns out to be a sensible thing to be concerned about
you will never reduce carbon dioxide emissions to zero per person; people emit carbon dioxide just by breathing. but the quantity determines whether or not it matters
the amount produced by burning garbage is a few times bigger than breathing
https://dercuano.github.io/notes/underground-arcology.html#a... has some of my notes on garbage; the high bit is that, in new york, residential and commercial waste is about a tonne per person per year, mostly things like paper and plastic which burn to carbon dioxide and water. so you might emit two tonnes of the dioxide per person per year by burning their trash
as explained in https://dercuano.github.io/notes/underground-arcology.html#a... a person breathing produces about a kg per day or 400 kg per year, hopefully sourced from the air via plants. so, too, is most of the combustible garbage
https://ourworldindata.org/co2-emissions explains that human carbon dioxide emissions are about 35 gigatonnes per year, about 4½ tonnes per person per year
now, probably people in new york throw away more garbage and burn more fossil fuels than average, so these numbers are maybe not as close as they appear; but the fossil fuels number doesn't make the potential garbage burnination number totally insignificant like i thought it would
