well theres a subset of countries that are reducing their emissions and a subset of countries that are not. perhaps we should punish the countries that are not.
I don't think that will help: https://www.worldometers.info/co2-emissions/co2-emissions-by...
Maybe you'll suggest changing that to be per capita? Punishing Palau, Qatar, and Kuwait?
You think we should punish countries because they should be cleaning up the CO2 generated by other countries?
the us is dramatically reducing its co2 footprint. the us currently is emitting per capita roughly what it emitted oer capita in 1910
if you didn't know this then its a pity your information sources are not telling you this.
Offshoring all the manufacturing and raw material processing elsewhere was convenient for claiming to create less CO2 discharge within the US - but is the US willing to forego all those shiny things that were created with offshore CO2 emission?
biggest contributor is that there was a flippening the us biggest trading partners shifted back to canada and mexico from china, under trump 1 iirc, which are way less bad emitters than china, and moving goods from those two countries incurs less co2 footprint for obvious reasons.
Rich (developed) countries created the CO2.
Marginal arguments that poor countries need to do their bit is insulting.
Most poor countries have never been able to afford to burn much oil and if us rich countries want them to change behaviours, we should be paying them to help clean up our mess.
Coal matters too. Methane is a temporary plaster over the main issue.
