Because humans just existing produces far less pollution than humans producing a lot of stuff.

It’s trivial to say that a bunch of hunter-gatherers don’t pollute much but we’re not generally willing to relegate people to living in the stone age.

Our economic choices have a much larger impact on pollution than our personal choices do. Ideally we’d have a measure of pollution per consumption. Everyone would have a score that calculates the total pollution created by the entire supply chain that supports their choices. So if a mine in Africa is polluting so a Chinese guy can have a nice air condition, that should be counted for China; and if a factory in China pollutes so that a guy in the US can have a new Iphone, that should be counted for the US.

I’m not aware of any such data set. The closest proxy would be GDP or GNP. That essentially provides a measure of how much pollution the total lifestyle of that population produces.

This has been going on for years and will continue.

China really really really needs a robust and diverse energy infrastructure. Industry needs huge amounts of energy. AI needs huge amounts of energy. The military needs huge amounts of energy.

Coal is unreliable and dirty. Oil can be blocked at the Straight of Malacca and a few pipelines.

China is also the world’s factory. They own the entire logistics chain for producing renewable generators; from raw materials to final assembly. They have all the infrastructure to not only build solar panels and wind turbines at scale, they’ve scaled up building the machines that build them.

Pollution per GDP is a better measure. https://ourworldindata.org/grapher/co2-intensity Pollution per GNP would be even better but I can’t find it.

Individuals don’t pollution much, it’s mostly industry. Really poor countries often don’t pollution much because they can’t afford to. Sometimes they pollute prodigiously because the only thing they can afford to do is destructive resource extraction. Rich countries can often outsource their pollution to poorer countries.

China has been making mind boggling investments in renewables. They have been expanding all their energy sources but their renewables have the lions share of the growth.

They’ve been building roads and all kinds of infrastructure. That’s what the BRI is all about, even if they’re being a bit quieter about saying the phrase. They like to build their long haul roads on elevated columns; not only because it’s less disruptive to wildlife but because it lets them use giant road laying robots to place prefab highway segments.

They dropped the one-child policy a while back but they’re having some trouble getting people to have more babies. That said, there’s some research that suggests that rural populations around the world are severely undercounted, so they may have a bunch more subsistence farmers than they, or anyone else, realizes.

I’d say there are two issues with it.

FIrst, it’s a very new article with only 3 citations. The authors seem like serious researchers but the paper itself is still in the, “hot off the presses” stage and wouldn’t qualify as “proven” yet.

It also doesn’t exactly say that books are copies. It says that in some models, it’s possible to extract some portions of some texts. They cite “1984” and “Harry Potter” as two books that can be extracted almost entirely, under some circumstances. They also find that, in general, extraction rates are below 1%.
