Sustainable Verifiable Credentials

I was reading
https://w3c.github.io/sustyweb/#manage-dependencies-appropriately

Perhaps the credentials community group would be interested in measuring
the emissions / CPU costs associated with issuing and verify various
competing credential formats, such as data integrity proofs, mDoc and
sd-jwt?

The VCWG could recommend against wasteful cryptographic operations or
dependencies that consume more CPU than is needed to sign or verify.
