Yesterday I saw a graph that blew my mind: https://ourworldindata.org/grapher/annual-co2-emissions-per-...

I had no idea.




I think the per-capita graph is more meaningful

https://ourworldindata.org/grapher/co-emissions-per-capita?t...


Is that more meaningful? My understanding is the climate is unconcerned with the per capita figure. It is concerned with total CO2.

To demonstrate, add some countries like Qatar, Montenegro, and Kuwait to that graph.

That it is concerned with the total CO2 is why per capita is the correct measure when determining if some group of people is doing better or worse than some other group of people at addressing CO2 emissions.

If you go by per country, then countries splitting or joining can change whether a group of people are emitting more or less than their fair share of the world's total CO2 budget. A high emissions country can simply split into multiple smaller low emissions countries. They are still emitting the same amount, but because they redrew some arbitrary lines on the map they are suddenly low emitters.

Take that to its logical conclusion and you get more and more splits, with the limit being a world of 7 billion countries, and per country then ends up being per capita anyway.


What happened in 2005-6 that started the emissions decline in the US and EU?

Interesting seeing the even more drastic decline in Russia’s emissions after 1991 with the fall of the USSR.

Edit: I found this anaylsis that credits the decrease towards many different factors, but largely driven by a switch from coal to natural gas. https://www.carbonbrief.org/analysis-why-us-carbon-emissions...


That seems to correspond with China emissions greatly increasing. Outsourced manufacturing with even worse CO2 emissions?


According to the graph, China’s emissions started rising significantly in the 60s, after their cultural revolution, presumably.

Besides, outsourcing manufacturing to China started many years before the mid 2000s.


Outsourcing of high-energy industries is part of it, but also that was around the time that wind and solar started becoming cost-competitive with gas and coal power.


Would be helpful to see this graph on a per-capita basis. Without accounting for differences in population, the utility is somewhat limited.


Yes I think it's really encouraging, the gloom and doom messaging really causes most people to tune out or ignore the situation.


Capitalism works. CO2 became uncool, so big money is to be made from selling green things.


The market is not working. What you see on the graph is a global growth of emissions. CO2 is a global problem, and we haven't improved on it yet, in any significant fashion.

If you are implying that the market has reduced emissions in developped countries, i believe you're reading the situation wrong: China has become the world's factory, and its emissions have exploded, but the products manufactures are exported and consumed in the most developped countries. So effectively, developped countries emissions have grown. It's trivial to understand this when you observe the explosion of goods and services available in these countries, at the press of a button. There was never in history that many objects around us, in developped countries. Our footprint on the global world is growing rapidly and has never decreased.

The market is failing to deal with climate change because the environment costs (sometimes called externalities) are not part of the market dynamics. The market uses money, but has a blind eye to anything physical. Business is just money and human labor. No mines, no pollution. It's all dollars. Polluting a lake is a X million dollars fee, not an irreversible loss in a one-time resource.


Of course it’s working. It’s just not done yet. How else did the US and EU lines turn sharply down in the mid 2000’s? Outsourcing to China has been going on for decades prior.

Now people have caught on to the fact that we need locally made things. There’s a huge push among my peers for things that are Made in USA or Made in Canada, and food grown within 100 miles, and things that are durable vs things that are plastic. My colleagues who work in manufacturing automation cannot keep up with the insane demand for onshoring production. I’m talking about everyday objects, but to further illustrate the idea: which car brand is currently the coolest, and why, and where is it made?

All of this is just here - remember they have a sort-of-free market in China. Once they reach the GDP per capita where most people care about such things as the environment, the same dynamic will play out there.

I agree that we should price in externalities though.
