In general I feel like no one really takes a holistic view of this and everyone just points fingers. If indeed all the models are correct and human-produced CO2 is causing global warming, it’s not just “corporations” or “the rich” or just individuals, it’s the whole of the machine of humanity hacking away at the tree branch they’re sitting on, and we need to radically shift our energy production to eliminate greenhouse gas externalities, and ideally figure out, what’s it called, CO2 sequestration or whatever, to bring it back to normal.
And to the degree we can’t shift immediately, we shouldn’t just be burning fossil fuels towards ends we don’t even need, like dumb luxury goods or just driving in circles. It does come down to all of us as individuals - some of us have more power than others (yeah, more or less proportionally to wealth), but the buck has to stop somewhere.
