Hi there, I’m noticing a spate of pieces recently making similar claims about the efficacy of carbon offsets: yours, Scott Alexander’s the other day and Connor Jennings recent post.

I would suggest folks be *much* more skeptical about cheap carbon offsets. Most of them are basically useless and operate more like religious indulgences. Failure points include additionality, leakage and especially permanence.

Regarding the latter, when I take a flight or use fossil fuel energy in any other way, I am removing carbon that was permanently sequestered underground and introducing it to the atmosphere and ocean. The downfall of most carbon credits and all of the cheap ones is that they merely bind up carbon temporarily in the form of biomass (forest management, tree planting etc) and therefore are not offsetting like with like.

The only worthwhile carbon credits are those that lead to verified permanent sequestration geologically by binding the carbon up with minerals underground or in the ocean. From what I can tell the cost of these methods is still on the order of hundreds of dollars per tCO2.

I think it’s really important to clear the air on this ☺️

Okay, I think I pretty strongly disagree, but perhaps I am misunderstanding. If the claim is that people should just donate more if you're interested in EA but not really invested enough to feel like you want to dedicate a bunch more time to it, then I agree with that.

I think the idea that people _should_ angle for earning-to-give instead of EA jobs is basically wrong though. I think if you're really interested in EA and competent, you should angle for an EA job. The case for this is basically very simple. Your money often goes to people who distribute it/allocate it/research the most effective ways to donate/do good things with it, and having amazing people in all those roles is also very very important. Money is only as good as what it's spent on, and I think this analysis misses that.

I mean, there's a reason why many organizations say they feel more "talent-constrained" than "funding-constrained" (though of course, many places are basically both talent and funding constrained to some extent). If you have the capacity to earn $1M in Jane Street, but instead spend your time working on how to most effectively distribute malaria nets in Africa, that can be _super high impact_, power-laws rule everything around me. Even within charities, the difference between an okay hire, a good hire, and a great hire are all massive!
