However, I am also wary of the push to view mitigations or "consumer behavior" generally as a means to actually deal with this kind of problem at scale. Like the whole carbon footprint thing BP was pushing for a while. Still in the public lexicon, doesn't do jack shit about real emissions at scale, but great for gotchas on activists. We have significant poison control and food quality control regulations because people can't really develop all the expertise necessary to vet all their own stuff, and it's a huge drain on society to make them do so rather than just solve that coordination problem centrally. Also, monopolistic consolidation has made even very organized boycotts dubiously feasible in forcing change in companies who respond more to their investors than their customers.
To me, governments exist to solve exactly this kind of problem, even though there are many other areas in which I would like them to mind their own business. In this case a lot of why petrochemicals are so cheap is because the cost of doing business for oil companies is heavily subsidized, so removing those subsidies wouldn't even require a new tax, and that money could be productively spent on lots of stuff, like maybe medical research even
