As an example of how absurd it gets, someone in my local nextdoor group posted something along the lines of “why should I reduce how much I drive when X% of emissions come from N companies”. Those companies are polluting so that you can drive!
People disagree on where the blame lies regarding consumption vs production, and it's difficult to know what is posturing and what is not.
I can’t buy Big Macs and then blame McDonalds for farming the cattle.
And then the individuals will change what they do, based on what is still available.
But absent a carbon tax, the idea that I can morally just consume willy-nilly and blame “corporations” is crazy. It's a form of moral laundering. Exxon isn't spewing CO2 for the heck of it, they're doing so as part of a production process that eventually some consumer demands. That consumer should not be let off the hook so easily.
