Holy smokes, these things generate a ton of CO2 if it takes a metric ton to store indefinitely on the blockchain.

That's apparently 1/5-1/8 the CO2 of RUNNING AN ENTIRE HOUSEHOLD FOR A YEAR.

The only way I see this as not being terrible is if the offset is much less bad on a yearly basis.

This also seems to be hundreds of times more CO2 than the average US internet user uses in a year.
