All 3 types of tokens are fungible. The audited emissions tokens are "retired" (see below) as soon as they're issued from an auditor to a company or consumer. The offsets and REC's could be traded but are eventually retired when used to count as emissions offsets.
Token Operations
- Add new token definition – Multiple types of emissions tokens can be supported on the network, such as emissions, Renewable Energy Certificates (REC's), and offsets.Mint – Authorizes a supply of tokens to be issued in the future, based on results of operations from audited companies and renewable/ offsets projects.
- Register/Unregister dealer – issuer – In our case, it would be registering and unregistering auditors or project certifiers authorized to issue tokens.
- Register/Unregister consumer – Auditors and project certifiers would register their customers on the network.
- Issue – Issues tokens based on results of operations from audited companies and renewable/offsets projects. Note that each issuer would be able to only issue allowed types of tokens, so an emissions auditor can issue Audited Emissions, a carbon offset developer or certifier Carbon offset tokens, and renewables developer REC's.
- Transfer – Transfer – In eThaler, the central bank transfers tokens to dealer banks. In our case, we would allow an auditor or project developer to create a token based on audited results and then transfer it to a party, which could be a business or individual. Emissions audit tokens cannot be transferred: They are retired as soon as issued and stay with the organization that was audited as a record of their emissions. Offsets and REC's can be transferred until they are retired. The total amount that could be transferred from one account to another is the sum of the tokens in their account minus the amount that has been retired.
- Retire - this is not in eThaler but would need to be implemented. When a token is marked as "retired," it is counted towards the emissions reduction of the retiring organization and cannot be transferred again.
- Burn – this would not be implemented.
