RE: Carbon credits VC

Snorre, 

 

I’d be interested as you get deeper into this project to understand what would drive a revocation event for an offset certificate. Do certificates represent a historical offset (a historical ‘fact’ that has been certified and not likely to change in the future) or a potential future offset that may need to be reconciled with actual values at some point in the future?

Thanks for that correction Steve, and sorry for my ignorance in what is what.

We just started conversations and im still understanding the scope.

But you are right, there is a certificate that is to be issued, and we will have to look at the revokability as well, according to the customer.

 

Thanks alot for these pointers and I need to dig more into this, but I found this as a context for JSON-LD, which matches some criterias: https://jargon.sh/user/unece/sustainability_vocab/v/working/artefacts/specification/render#climatecarbon

When it comes to the project part, let me have an internal discussion first before we venture down a road like that. But thanks alot for this feedback!
I will get back to you privately when I have some more to go from.

If anyone else have any good pointers, please send them along this email thread :D

Hi Snorre,

 

Did you really mean "carbon credit" VC ? or did you mean Carbon offset certificate for manufactured / traded products?  

* A credit is a tradeable item - so more of an NFT than a VC
* A certificate is a great candidate for a VC.  

If you want a global standard for something like a Carbon offset VC then you need a global authority to define it.  One option could be UN/CEFACT - they are just "modernising" their standards development framework around github - see https://github.com/uncefact. Also, they've just published a white paper on VCs for cross border trade (see the one at the top of the list at https://unece.org/trade/uncefact/guidance-material) so might be ready to start a project on cross border carbon offset certificates?  I can facilitate introductions if you'd like to participate in ap project to define that

Hi!

 

Have anyone in this community worked on carbon credit VCs, and built out a context or a good VC data model for these data points?

 

Maybe a global version that one can reuse?
