The following table is from Scott Alexander’s post, which you should check out for the sources and (many, many) caveats.
This table can’t tell you what your ethical duties are. I’m concerned it will make some people feel like whatever they do is just a drop in the bucket—all you have to do is spend 11,000 hours without air conditioning, and you’ll have saved the same amount of carbon an F-35 burns on one airstrike! But I think the most important thing it could convince you of is that if you were previously planning on letting yourself be miserable to save carbon, you should buy carbon offsets instead. Instead of boiling yourself alive all summer, spend between $0.04 and $2.50 an hour to offset your air conditioning use.
