My personal (skeptical) benchmark for price per unit of non-garbage carbon offsets comes from Scott Alexander’s mention of Climeworks:
“Pessimistic” comes from Climeworks, a company that builds giant reverse-factories which take carbon out of the air. If you’re maximally skeptical about any charity’s ability to offset CO2, these are the people for you—they can literally hand you a bottle full of the carbon they removed, so you don’t need to take anything on faith. But they charge as much as $1000/ton.
Climeworks actually charges more now, at least for their individual subscription pricing: $1,500/ton, no volume discount across subscription tiers.
I like the idea of immediately donating the same amount or more to effective environmental funds, thanks for sharing.
