Bertrand WILLIAMSRIOUXIs the C-NFT linking back to the Audited Emissions tokens somehow for example through metadata or a field on the token?

The C-NFT links directly to a tokenId
Each C-NFT has a mapping(uint => CarbonTrackerMappings) internal _trackerMappings;
the struct for CarbonTrackerMappings includes and array of tokenIds
struct CarbonTrackerMappings {
mapping(uint => uint) amount;
uint[] tokenIds;
...
}
For now I am using NET (tokenTypeId=4 for Carbon Tracker Emission token) when issuing tokens to a C-NFT contract, as these are non-retired audited emissions certificates. I modified NET so only Emission Auditors can issue tokenTypeId=4.
We could use retired Audited emission certificates, unless there is reason to transfer the C-NFT tokens to a registered Consumer address when tracking is complete.
