I don’t necessarily disagree with you per se, but I do think these “EV-lite” type analyses are too broad: environmentally conscious people may be more likely to have children who are environmentally conscious, work on climate engineering, &c. That’s not to say that we should encourage them specifically to have children either; just that children represent potential in a way that the number of bunker-fuel cargo ships…

Even the most environmentally conscious person in an industrialized nation will emit massive amounts of CO2 in their lifetime, provided of course that nobody invents a "quick fix" for CO2 emissions in their lifetime. Of course in theory the child could be that person to invent that quick fix, but the expected value is still that the child will contribute to a lot of CO2 emissions.

The point is that "will emit massive amounts of CO2" isn't a complex enough metric: if that's how we're calculating EV (which I disagree with in the first place), then it would be perfectly appropriate for me to go around killing truck drivers and suburbanites.

(Controversial comment warning) one way to save more than your lifetime’s worth of CO2 is to not have children. By not having children, you’re not just saving the CO2 output of the child itself, but the entire lineage that could have resulted from that single child. Obviously this advice is not good advice for anyone who wants to have children :)

It's also not great advice for humanity. Better to have a CO2 high future than no future at all.

They might be the same future though.

The humans making the cost/benefit analysis are largely the ones whose cost is actually external. I certainly wouldn’t do the same math, but I’m not casually enriching myself by making people sick. The people who buy their products are largely their victims, not their accomplices. Nearly everyone does NOT own the means of production, and the few who do know exactly what’s wrong and keep on doing it to everyone but th…

Technically, Blackrock and Vanguard own the means of production. We gave them the capital to do so through our pensions and 401(k)s. My 401(k) menu doesn't include ESG funds, but those that exist have higher expenses and lower performance than an indiscriminate index fund. If the regulators have been captured by lobbying and revolving doors to industry, the only option left is to vote with your wallet, but that's eas…

Divestment without regulations doesn't work. You dumping your polluting investments is just someone else's opportunity to pick them up for cheap and make a profit.

Voting with your wallet is noble, but pointless. Vote with your actual vote.

> A globally coordinated reduction in production only increases the price of products for consumers. Which is great. Higher prices = less usage. We don't have to eradicate them entirely before we see any benefit.

>Which is great. Higher prices = less usage. Don't lie to us by not mentioning the tradeoffs. Reduced standards of living = less spare f-s to give about abstract big picture issues (like pollution and climate change).

Who knows? Maybe better health = more spare f-s to give about abstract big picture issues.

3M has been facing a raft of litigation that has prompted the move Generally speaking, toxic substances are only "cheap" due to externalizing many of the costs involved, like increased healthcare costs and lost productivity. If you do a thorough analysis of the costs of using such chemicals, they aren't cheap at all. Maybe someday humans will get that.

The same thing applies to many other activities: fossil fuels, usage of single-use plastics that someone else will clean up, promotion of unhealthy and addictive substances like tobacco, etc.

I am skeptic that market mechanisms achieve the best outcomes at all times, but I'm positively certain they don't when externalities are not even priced in!

This is the prisoner's dilemma situation. Everyone would benefit more from a reduction, but if only one company does it, they benefit (in the short term) even more. I think the signalling is also valuable -- humans have a remarkable tendency to adopt attitudes over time, and I think every contribution towards the attitude that we should not harm the environment is a good one. I for one currently support and will cont…

Just to chime in about your use of the word "signaling" and when others use "virtue signaling". I believe the traditional term is "setting a good example" and even if the motivation is selfish there's a positive outcome. "Virtue signaling" was invented to demonize this behavior by focusing on (the assumed) motive as selfish.

The use of the phrase "virtue signaling" tells me immediately that the rest of the comment has absolutely no value whatsoever and can be safely ignored.

I'm not sure this is a win for the environment or human health. 3M is gifting sales to it's competition to avoid future liabilities. Chinese companies are ready to pick up the slack. 3M is certainly developing safer alternatives, but until they are as good and as cheap, companies will buy their toxins elsewhere.

We ban imports of Chinese PFAS, and the damage gets mostly localized to China.

About a quarter of new pharmaceuticals are PFAS, and we can’t make modern chips, autos, or airplanes without them. Once politicians learn that the half life for “forever” chemicals varies by 7 orders of magnitude, we will have more nuance about the issue.

> About a quarter of new pharmaceuticals are PFAS

Huh, TIL. I was going to rebut this but I looked into it. I didn't realize simply the presence of a -CF3 group is enough to classify the whole molecule as a PFAS according to new definitions.

> More recently (2021) the Organisation for Economic Co-operation and Development (OECD) expanded the definition, stating that "PFASs are defined as fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom (without any H/Cl/Br/I atom attached to it), i.e. with a few noted exceptions, any chemical with at least a perfluorinated methyl group (–CF3) or a perfluorinated methylene group (–CF2–) is a PFAS."[3][4]

That's a super popular moeity in medchem for whatever reason, so yeah, RIP all thing trifluoromethyl.

Difluromethylene can be degraded much more quickly as long as the molecule can be "unzipped" (needs a break point where nucleophilic attack can occur), so it's possible we may be able to sub in -CHF2 or -CH2F to "cap" molecules and render them less persistent.

That's in the range of 10x the CO2 an average human will produce in their lifetime. If you could find a way to get 20 people to cut their emissions in half, or 200 people to reduce it by 5%, or 1000 people by 1%, you could balance out your CO2 ledger :) Or, if you still work in the industry and can find a way to make the shipping routes more efficient, or prevent future mistakes like that, you could make it into the…

That's true. It's also an entirely different tragedy of the commons. If nobody has children, we are going to be screwed when our generation is too old to work.

Zojirushi also makes them without the liner. It’s a choose-your-poison situation: the lined ones seem to perform much better with green tea.

Interesting, I wasn't aware of that. What do you mean by "perform" here?

Could be the green tea is made with slightly lower temperature water so less likely to leach chemicals off of the liner
