- CI of oil & gas supplied (Fuel trade out) -> flared gas + leakage / fuel outputs
- CI of Refined fuel trade -> other emissions (e.g., electricity/heat, flue gases) / refined fuel out
The consume consumer can reduce (or compl)y with a desired CI standard by purchasing carbon tokens from a low methane supplier. This token transfer could be arranged without physically taking delivery of the fuel. The NFT(s) simply provides a methane performance certificates for the output fuel tokens, helping producers with lower carbon intensity to obtain greater value for their products. A CI certificate is simply a transferrable claim of origin backed up by data. It is similar to a Renewable Energy Certificate (REC), but whereas a REC attests that electricity produced is from a renewable source, the CI certificate attests the total emissions of the fuel produced.
