At the end of the day, it's one ecosystem we all live it. It doesn't matter if the top polluter has 1 billion, 0.1 billion, or 10 billion people. The total amount of greenhouses gasses added to the atmosphere is too much. We all need to stop adding and then start removing.

As for which metric to use, that depends on the argument you want to make. One can look at cumulative emissions and see how western nations have polluted much more historically, and should therefore do much more to clean up a mess their have contributed much more to.

Their governments will retort: "Oh but we produce so little of current global emissions now, those other countries polluting more should change first".

Each polluter is an individual person making individual decisions.

The thing people are dancing around is any concept of "rationing", because that's political suicide, but at the same time asking people who've only just got clean water and walk to work to reduce emissions while other people are taking multiple transatlantic flights per week looks a bit questionable.

I don’t know who those people are. Also, another way to say rationing is “sharing”.

But why are countries the best division? Why not continents, or unions of countries (e.g. EU or USA), or sub-country divisions like states, or even smaller regions? Countries don't have the highest possible impact on all people, that would probably be unions. It's also not the most direct impact, that would depend on each country, but for e.g. Germany that would be the individual states.

The per-capita measurement allows you to directly and meaningfully compare any subdivision, while per-country isn't even meaningfully comparable with other per-country measurements.

Compare to what end? The environment cares about total output, not per capita output.

Why does it need to be?

Yes, and the environment does not care in any way about countries or other silly subdivisions. So we approach the problem as each of us humans having some carbon budget based on the limits of our environment. You can argue how exactly these budgets are distributed, but it's the only measure that matters. Because again: you're arbitrarily choosing to look at countries, when even other subdivisions along the same axis would make more sense. So why focus on countries specifically?

> Why does it need to be?

Because obviously a measurement that's comparable is more useful than one that isn't. It allows us to make determinations about what changes bring us closer to the goal of environmental sustainability, and which changes bring us further away. Do I really need to go on further?

> So why focus on countries specifically?

Because it is at the country level that people corporate on international problems. And in many countries it is the federal (or equivalent level) which has the money required to build out the kind of projects needed change those numbers (or the legal authority to mandate it).

Ahh. I misunderstood what you meant. > while per-country isn't even meaningfully comparable with other per-country measurements.

I interpreted as “other per-country measurements” as (other measurements) not (same metric, different country).

I still think it’s not relevant. The changes and the target are still the same, i.e. stop burning shit.

> Because it is at the country level that people corporate on international problems.

It's also at the union level that people corporate on international problems, arguably more so than on the country level. Yet the largest differences occur at the regional level. Both would be more comparable, and would capture arguably more useful information. I just don't see how an arbitrary and incomparable measurement is better than one without those flaws.

> I still think it’s not relevant. The changes and the target are still the same, i.e. stop burning shit.

Yes, but it's easier to implement the necessary changes if everyone tries. It will be much harder to get the necessary investment from all voting populations if large discrepancies exist between groups of people.

I think we’re talking about different things now. I’m saying that emissions should be measured one absolute levels per country since a) absolute pollution is what matters and) countries are the political blocks that dictate international laws and cooperations.

You seem to be talking about the groupings by unions and regions. I am unconvinced that people have a stronger affiliation for those than their country. Further, measuring emissions levels for the country as a whole. On a practical level, getting emission levels for a specific region or a specific union, must less particular individuals, is going to be much harder.
