This is the emissions token network from the Operating System for Climate A= ction.
You can try it yourself at https://emissions-test.op= entaps.org/. You will need = to an Avalanche Fuji testnet wallet and some test eth (which you can get = span>here.) Then please email Climate SIG mailing list with your = address to be added to it.
The emissions tokens network uses tokens to represent the emissions of a= n entity, which could be an organization, a building, or even a person.&nbs= p; It is the sum of all the emissions from different channels such as the <= a href=3D"/display/CASIG/Emissions+Data+Channel">utility emissions channel<= /a>, plus offsetting Renewable Energy Certificates and carbon offsets. = ; Each token represents either an emissions debt, which you incur thro= ugh activities that emit greenhouse gases, or an emissions credit, which of= fset the debt by removing emissions from the atmosphere.
The carbon emissions token is a fungible token, whereas data on the util= ity emissions channel are just immutable data (not tokens), as they represe= nt the emissions from a particular meter tied to a particular utility durin= g a particular period of time. Following examples from capital market= s, we can link this kind of data to the fungible tokens by:
We propose to implement a carbon emissions token based on the eThaler project from the Financial Markets SIG. eThaler is a Central Bank D= igital Currency (CBDC) implemented on a private Ethereum network running Hy= perledger Besu. It supports a central bank which creates and mints to= kens and transfers them to member banks, who would then distribute them to = retail customers of the banks.
In the case of carbon emissions, the eThaler smart contracts could suppo= rt the following participants on a tokens network:
The audited emissions tokens are "retired" (see below) as soon as they'r= e issued from an auditor to a company or consumer. The offsets and RE= C's could be traded but are eventually retired when used to count as emissi= ons offsets.
The Carbon Emissions token taxon= omy developed by the Interwork Alliance is similar to eThaler's to= ken taxonomy. The differences are:
The emissions tokens would have the following fields:
Examples of these tokens/assets include:
With these tokens, we can calculate the net emissions by first subtracti= ng the effect of Renewable Energy Certificates (REC's.) REC's offset = the energy produced by non-renewable sources in designated jurisdictions. T= his feature requires differentiation of the non-renewable from renewable en= ergy to be specified in the original emissions tokens/assets from utility e= missions data channel. Then we subtract the offsets to get the net em= issions in the jurisdictions that allow that accounting method.
This network would be connected with Fabric channels such as the utility emissions channel th= rough the auditors. The utility emissions channel is operated by an a= uditor on behalf of its customers. The auditor would also be on this = network and would issue audited emissions tokens to its customers' wallets.= The customers would then transact in emissions and offsets on this n= etwork using their wallets.

Transfer of emissions down the supply chain and avoiding double counting= are major issues to be addressed in the future. The problem is that = emissions are counted in multiple ledgers, for example this docum= ent from Gold Standard describes how they could be counted in both offs= ets and national registries. See also the Gold Standard = double counting guidelines document. Doesn't including the interval= dates, location coordinates, and tax map key in the metadata prevent doubl= e counting?
