While carbon audits and certifications are complex, a lot of data could be obtained automatically now. For example, utility bills, corporate travel, server usage, and shipping data could all be obtained by API calls. This means that if you work for a professional services such as software or IT consulting, an automated system using the blockchain could audit your company's emissions and certify your company as carbon neutral.As an initial proof of concept or We're working on a Carbon Neutral Certification Minimum Viable Product (MVP), we could
- Create a Hyperledger permissioned chain
- Set up separate channels for different organizations
- Allow data to be published to the channels and signed. The data would include basic information about the organization and digitally obtained energy usage data, for example from utility bills. They would be stored on the ledger in JSON format, for example:
{ "date" : "2020-05-29",
"value" : 1200,
"unit" : "kWh",
"source" : "UtilityAPI Green Button XML",
"raw" : // full dump of original data if available }
- Deploy chain code to calculate the organizations' GHG emissions
- Publish the GHG emissions as a token or asset.
- From a combination of activity data (units produced and value of production) and energy data (electric utility bills, emissions factors, any Renewable Energy Certificates applied), we can calculate the per unit emissions factors for the company's products. These can then be published on a public token to be passed up and down the supply chain.

which will provide a demonstration of how to do this with Hyperledger.
