In recent years, the Environmental Defense Fund, major oil companies and the Oil and Gas Climate Initiative, international organizations such as the United Nations Environmental Program and the World Bank, and institutional investors have made an effort to reduce methane leakage and flaring. Nevertheless, this remains a difficult goal to achieve because of a lack of data and proper financial incentives. Many oil wells do not have equipment to record how they are handling methane, and many companies simply do not report . Even if they do this information is stuck in data silos, making it difficult to share and verify reported values. As a result, each year at least $50 billion worth of methane is flared rather than being sold as a commodity (natural gas) and extracting rents from investing in infrastructure to capture it.

Through this we hope to help provide greater visibility to the oil producers, their investors, government agencies and NGO's involved in reducing methane flaring and leakage. We also hope to create an additional lever, where fuel consumers can actively participate by purchasing emission reduction and methane performance certificates.
The Solution
We propose to use a blockchain oracle, such as Chainlink, to integrate the different sources of data from methane emissions. Several independent sources, such as GGFR, Flaring Monitor, MethaneSat, UNEP IMEO, flare-intel, could be combined with company reported figures to arrive at an answer. A blockchain oracle assigns tokens for each source of data and weighs the data according to the tokens held by its source. It could increase or decrease the tokens for each data source as the data is subsequently validated or refuted.

A CI certificate is simply a transferrable claim of origin backed up by data. The NFT(s) provide a methane performance certificates for the output fuel tokens, helping producers with lower carbon intensity to obtain greater value for their products. 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. The consumer can reduce their fuel CI by purchasing carbon tokens from a low methane emission supplier. Emission profile certificates tied to carbon tokens could be transferred between two users of fuel so that a user which is looking to reduce its emissions footprint could pay for a lower carbon fuel, without physically taking delivery of it. This would require simultaneously transferring, with the aid of a smart contract, fuel tokens between the certificate sender and receiver and subtracting the embedded emissions of the fuel inventory of the consumer and adding back it to the embedded emissions of the fuel inventory of the producer. In future transactions, the producer would have to attach a higher CI to the fuel it sells as it sells certificates of lower embedded emissions. This creates a mechanism where a producer of lower carbon fuels could monetize greater value for their output.
As an example:
- Supplier has 1 million gallons of diesel with a carbon intensity of 9.88 kgCO2e per gallon (see EIA estimates.)
- Customer has 100,000 gallons of diesel with a measured carbon intensity of 12.88 kgCO2e per gallon, from a high methane flaring producer.
- The customer wants to lower the carbon intensity of their fuel to 7.9 (20% below average), so they need to purchase -(12.88 - 7.9) * 100,000 = -498,000 kgCO2e carbon intensity from supplier through a certificate.
- After the transaction, the supplier still has 1,000,000 gallons of diesel, but they can no longer sell them with a carbon intensity of 9.88. Having sold the customer -498,000 kgCO2e carbon intensity, they now have 9.88 * 1,000,000 + 78,987 = 10,378,000 million kgCO2e of carbon intensity.
- So in future sales, the supplier must now claim carbon intensity 10.378 per gallon and pass them to its customers..
In contrast, an offset is an accounting of emissions reduction in return for an investment, such as equipment for capturing, storing, and transporting methane This creates an incentive to make capital investments at high carbon intensity producers to reduce them. To be valid, an offset must follow the general principles of carbon offsets, such as Additionality, Correct Baseline, Permanence, Real, and Leakage protection – In other words, the emissions reductions must not have occurred without the investment from the buyers of the offsets. The offset would be a token which would transfer the emissions reductions to the buyers of the offsets, which again could be a fuel user.

- company voluntary reports/ ERP sensors (gas flaring)
- independent tracking service such as Flaring Monitor

According to the GHG Protocol Guidance on Upstream Transportation and Distribution, supplier provided carbon intensity is an acceptable metric for calculating GHG emissions and preferred over industry averages and model based figures.

CarbonChain is a comparable solution to help organizations assess emission impacts across commodity supply chains. However, it operates as a centralized services, focusing on gathering data into a bigger silo, rather than connecting them.
