Which means that they emit much less per person. Or should countries be compared with no refrerence to their population, in which case Saudi Arabia is doing great?
Additionally, USA has had decades of relative prosperity to clean up its emissions, but did nothing.
Meanwhile China has more electric busses than the rest of the world combined, more hifgh-speed raio than the rest of the world combined, lead the world in investment in renewables and nuclear and are on track to meet their Paris accord commitment, unlike US.
Looking at it per population is kind of ridiculous when it's very obviously corporations and manufacturing responsible for most green house gasses. The average person barely makes a difference both in regards to pollution, resource consumption and plastics.
You have a point, but population is still the key metric. Corporatuons are, after all, made up of people. Whether those people produce emissions in their private life, or in their jobs.
Furthermore this is a production based accounting of CO2, if you instead do consumption-based accounting of CO2 then you will see a dramativally more savage picture.
Easily fact checked. China doubles the US on both Co2 and Methane emissions.
Edit: Got downvoted, but it's still true the above post is outright incorrect information.
