I don’t know why you’re getting downvoted. We need to do all the things at the same time. We need corporations to change their ways (which means boycotts, protest, and likely sabotage), we need governments to do their share (which means voting, protests, and general civic engagement at all levels), and we need consumers to accept that their lifestyles will have to change.
To actually make those changes to consumer behavior, we need good public policy decisions and for corporations to not obstruct things. Without good governmental policy, consumers will not be able to make those switches. Without consumer behavior changes and good governmental policy, corporations will kill any chance at change.
(I do think the framing could be better, but I don’t think blaming the working class is a good description of what’s happening.)
This isn’t GHGs, they’re talking about like smog and particulate pollution, Sulfur Dioxide is what primarily caused acid rain, CO is toxic. We still won’t peak GHG concentrations for a while, as that requires net zero emissions.
