I’m saying that before very long China will emit more per capita than the US does too, because US emissions per capita keep falling while China’s keep skyrocketing.

So, no, even when you take population into account China is a bad emitter and not doing nearly enough to invest in decarbonising their economy in the same way the US and EU have.

>US emissions per capita keep falling while China’s keep skyrocketing.

It's sus to ascribe countries as bad emitters because they're developing higher QoL instead of choosing to be stuck as subsistence shitholes with low per capita emissions. The only way for countries to stay at subsistence/developing per capita emissions is to stay susbsistent/developing. Of course some wierd people think that's fine.

A fairer description is PRC's moderate per capita emissions are converging with US high per capita emissions as QoL improves because average PRC citizen wants to live as well as average citizens of high consumption developed economies. But due to various physical constraints - less square footage per, less flying, less car ownership per capita due to density, PRC unlikely to pass US per capita - they're simply not setup to enable car centric, house+lawn levels of consumption. But PRC converging with west in QoL = PRC still primed for more catchup consumption = per capita emissions still has room to climb, while transitioning energy mix tries to sustain growth via greener methods of generation.

Meanwhile US's process of "decarbonization" = also becoming net oil exporter and largest lng exporter, the latter with evidence to be much more poluting than coal due to leaky infra. Which BTW adds, ~3 tons co2 per capita to US produced emissions, which single handly negates last 15 years of US "falling" emissions. Which BTW should be accounted for US emissions just like PRC exports are calculated in PRC emissions, but conveniently isn't. Meanwhile, PRC upgrading domestic coal to be cleaner, ceased construction of coal plants abroad, is net exporting green energy. That's without bringing population growth/decline trends. US adding 1.5m to US tier of emissions is like adding 12m Indians per year.

Whether a country is a bad emitter is a factor of its total and per capita emissions. It has no inherent moral meaning, but it has serious implications for how we can slow down climate change.

At current rates, China is going to be a larger per capita polluter than the US ever was, because it’s still choosing the quick, cheap, and dirty approach to so much of its industry including those focused only internally. As a result of poor central planning and incentives, it has built and then destroyed entire apartment blocks in cities across the country without them ever having been in use. Its per capita emissions rate is already higher than that of the EU average.

Nobody on here is saying that China or any other country shouldn’t develop. It’s expected that there’ll be a rise in per capita emissions as a result. But that doesn’t mean that China has the right to emit as much as it can just in the name of development, especially when so many lower carbon options exist.

Again, this isn’t a moral judgement, where adding focus to China means taking focus away from the US and letting it do what it wants. Nor is it a situation where we can or should give anyone a free pass just because of history. Instead, we’re in a situation where we’re collectively screwed unless we can reduce total emissions and China has to be an integral part of that reduction too. Just as the US has to be.

>At current rates

This presumes current rates holds, when rate is constrained by factors and levels off past certain thresholds of development, and inherent constraints limit PRC demands vs US. With geography/population/density constrains, average PRC household isn't going to average 2300+ sqft of space & 2 car household, so trend of PRC per capita emissions passing US not realistic extrapolation.

>poor central planning

Wasting a few 100 apartment blocks over decades (for corruption/wrong zoning) doesn't meaningfully adds to per capita emissions. It's a rounding error on scale of millions of normal housing upgrading/recycling/replacement cycle over time. Even currenty underutilized housing is mostly reflection of short term supply outstripping demand. PRC still has 300m people to urbanize and net short 100s millions of housing units. Upgrade housing also important in development, moving people from dilapidated huts to modern buildings requires emissions.

> Its per capita emissions rate is already higher than that of the EU average.

Catchup growth = pouring down 100 years worth of concrete + steel, aka generations of infrastructure. In that sense per capita emissions is a concession to developed countries, since real useful index is historic per capita emissions, aka how much energy was expended in totality to enable modern/developed levels of QoL. PRC simply very good at condensing all this grown in a few years, other developing countries will follow, but spread over time, with longer tail.

>can just in the name of development, especially when so many lower carbon options exist.

PRC emitted relative to tech available at time. They upgraded coal to clean coal. They jumped on electrifiction / renewables at scale when it was feasible to deploy at scale. Prior to that the tech didn't exist economically, nor at scale, and hence might as well not exist. They would have jumped on nuclear sooner if western contractors didn't shit bed. TLDR is cleaning energy didn't scale with PRC growth, one doesn't slow compounding growth and development because tech isn't ready because effects of growth > emissions.

>moral judgement

Choosing position that prioritizes emission over development and vice versa is moral choice since it prioritizes effects of climate change to effects of development. My position is development > climate always since second order effects of development (poverty alleviation) > emissions/long term health. My other position is climate change is anthropocene problem, earth doesn't care we die in ice age or fire ball. Anthropocene solutions to anthropocene problem = geopolitical compromises, not what's best for science/enviroment. And only metric world can realistically agree on is per capita metric, in which case lead emitters sets the standard for what's allowable, and if that level pushes everyone over the edge, then that's where we'll "fairly" go, because that's want's ultimately morally acceptable/feasible.

there's no reason for you to reply to maxglute. they never quote anything for reference, preferring to hallucinate things out of thin air. and they always want to have the last word, which is a sign of immaturity/insecurity.

China is doing a lot to decarbonise its economy, probably more than anyone, and is still poorer than the US.

Again, you also need to take into account that the US and EU have outsourced emissions to China, which needed that to develop. Still the US emit a huge amount per capita so it's disingenuous so claim that China is a bad emitter, which feels like the US is trying too hard to deflect.

Re:Fastest rate of natural carbon dioxide rise over the last... by _djo_ on Wednesday May 15, 2024 @11:37AM (#40368347)
They’re clearly not doing more than anyone given that their emissions rate per capita and as a proportion of industrial output keeps climbing.

Claiming the US and EU ‘outsourced’ emissions to China is an overly simplistic view, and one that ignores the way China developed its own industry and targeted the developing world as a market for its goods long before US and EU companies outsourced en masse.

China now emits more than 60% as much per capita as the US, where thirty years ago it was more like 5%. In fact, China’s emissions have been so high in the past thirty years that their total emissions are now also up to more than half of all US emissions since 1850.

So, yes, China is a bad emitter and has already contributed more to global warming than anyone other than the US. What’s more, their emissions growth rate remains unsustainably high.

Also, none of what I’ve been saying is about deflecting blame from the US. It’s had a huge part to play in global warming too, and needs to do a lot more.

China was very poor and has been developing... It does not mean that they aren't doing a lot, and probably more than the US do.

> In fact, China’s emissions have been so high in the past thirty years that their total emissions are now also up to more than half of all US emissions since 1850.

Chinas has more than 1.4 billion people now while the US have 333 million and 23 million in 1850... Still China will never reach the emissions per capita level that the US did in the past.

> China is a bad emitter and has already contributed more to global warming than anyone other than the US

That's a highly disingenuous claim, again ignoring population and development, as well as size of global economy.

If you keep ignoring that China has a massive population and is still a developing country, with inhabitants still poorer on average than Europeans and Americans then there cannot be an honest discussion.

What's the US' "excuse" for emitting more than even the EU per capita? They have the best technology and unlimited funds. But, oh yes, it's China who's the bad emitter...

What part of per capita are you not getting?
Re:Fastest rate of natural carbon dioxide rise over the last... by mytailorisrich on Wednesday May 15, 2024 @02:48PM (#40370827)
No snark, please. It seems that you are not getting what I wrote:

Regarding per capita figure the thing to keep in mind is that China used to be very poor and has been developing. Per capita figures therefore started very low and have been increasing rapidly with development, and are still much lower than the US's. This is also why India's figures are quite low.

Regading overall figures, obviously then what is relevant is the overall population, as explained.

Can't repeat the same thing over and over if you refuse to engage, so good night and good luck.

I apologise for the snark, my frustration for the better of me.

The point I’m trying to make is that I’ve been basing all my points on per capita emissions, not overall figures, and that China’s per capita figures are no longer much lower than those of the US and within just a few years at the current rate they will eclipse US figures.

That means that it’s not just about them developing, it’s also about them developing in an extremely emissions-heavy way, to a point where if nothing is done there’s a possibility that before long China will have per capita emissions several times larger than that of the US. Of course, given their population that also means their overall emissions will be huge, but that’s a separate thing.
