the problem with blaming companies is none of them do this out of desire to hurt the environment. they do it to meet customer demand.
as an example imagine if we all stopped buying gas from Shell. their environmental impact would plummet…and their competitors impact would go up as we continue to buy the same amount of gas from other companies
All I can think of are some variations of you trusting a service to validate your id and give you a token that just asserts your id has been validated.
But it’s still not really privacy preserving because it relies on trusting both parties to not collaborate against your privacy. if at some point the id provider decides to start keeping records of what tokens were generated from your id, and the service provider tracking what was consumes with that token, then you can still put it all back together.
