Innovation Tagline: Using the blockchain to create supply chain incentive to help reduce up to 1 Gt CO2e of Greenhouse Gas emissions per year.

Problem
Under any reasonable scenario, While the world tries to avert the worst of climate change, most scenarios still show the oil and gas industry will remain remaining a significant and important part of the global energy system for several decades to come. During this transition, however, we must do everything possible to reduce the climate impact from continued use of fossil fuels.
The first priority should be reducing A top priority for doing so is to reduce the amount of methane that is leaked and flared during the production of oil and natural gas. Flaring , and venting , of natural gas at oil wells happens because methane is trapped in the geological formations of the oil wells. During the extraction of oil and gas, it must be removed to keep the well operating safely. In some wells, this methane is captured and sold profitably as natural gas. In other wells, such as especially those located in remote areas, the lack of pipelines or other infrastructure to transport the natural gas makes it uneconomical to do so. In those cases, it is simply burned (flared) or, worse still, released directly to the atmosphere.
Because methane has 25 times the climate impact of CO2, this methane leakage and flaring is a major source of global Greenhouse Gas (GHG) emissions. The Environmental Defense Fund estimates the total global oil and gas methane leakage and flaring at between 250 Mt to 1 Gt CO2e per year (Figure 1). The latter amount is greater than the total emissions of Germany and or all the world's airlines combined.
...
In recent years, there has been a concerted effort on the part of The Environmental Defense Fund, major oil companies and the Oil and Gas Climate Initiative, major international oil companies, international organizations such as the United Nations Environmental Program, and institutional investors 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 excess underground methane, and many companies do not report on the level of the methane that is released. As a result, even though methane is a valuable commodity (natural gas), it is not possible to estimate the value that could be captured from the leaked or flared methane and therefore determine the returns from investing in infrastructure to capture them.

In this project, we will work on using the blockchain to provide trusted data on methane and transfer that data to fuel consumers to incentivize methane reduction at the point of production. The first part of the project will integrate data from different sources to arrive at the best estimate of the methane emissions of a facility. The second part of the project will use Value chain (scope 3) reporting standards to calculate the impact of methane emissions reduction on the fuel used by customers.
According to the Carbon Disclosure Project (CDP) value chain reporting has not been very successful in reducing emissions (Patchell 2018).
Value chain reporting may use the Life Cycle Assessment (LCA) practice, which can be difficult for organizations to implement on their:
- Access the credible metrics restricted by data silos across emission measurement, reporting and verification (MRV) systems
- Rely on historic data based that may be several years old
- Employ of on model estimates that may be subjective and hard to validate
LCA applied to fuel carbon intensity standards have no been very effective in mitigating emissions (Plevin et al 2017). It could then be used as part of the Supply Chain Decarbonization Project to incentivize the use of lower

- Voluntary Carbon Tracker Token (VCT) could be used by industry members to note the amount of methane emissions associated with the oil or natural gas produced at the well.
- Audited Emission Certificate (AEC) could then be assigned to energy consumers based on the VCT. Fuel from high methane wells would have higher embedded emission for whoever consumes it.
- Credits similar could be issued to transfer the lower embedded methane emissions from one party to another, helping them meet their emissions reduction goals while providing incentives to reduce methane emissions at the well.
In this example of an energy value chain, imagine an oil & gas producer or well extracts the crude oil from the ground. A utility power plant then produces the heat and electricity which is used by a refinery to process the crude oil into fuel products, such as gasoline for cars, diesel for heavy transportation, and kerosene or jet fuel for aircraft. A C-NFT provides a digital emission profile for accounts owned by facilities, e.g., oil and gas field, power plant, refinery (Figure 2).:

Each profile step in this value chain (reporting "silo") consists of inputs and outputs as NET transaction values - , which are transacted using the Net Emissions Token (NET) network, in Carbon Dioxide equivalent (CO2e) of Greenhouse Gas emissions. Based on the Value chain (scope 3) reporting standards:
- Inputs are retired NETs for direct (scope 1) emissions due to fuel burned or indirect emissions for purchased energy (scope 2/) or downstream emissions (scope 3) emissions.
- Outputs are tokens tokens transferred downstream to the users of the fuel, such as freight companies or airlines.
- VCT are transferred as the CO2e of fuels sold to consumers (used in commercial trade).
- AEC are indirect emissions, e.g., from selling electricity/heat
Emission profiles can explicitly reference a source C-NFT (arrows in Figure 2) to track embedded emissions, for example the crude oil or the heat and electricity supplied by the power plant that went into the finished products.
In practice, we envision a supplier /emission dealer announces to its customer, I am sending sends an emissions tokens (e.g. VCT) from this facility's emission profile (NFT). This to its customer using the oracle-validated methane flaring data. This emissions token is an NFT which allows organizations to connect bridge the internal boundaries of traditional data silos to get a complete view of the energy value chain. It is attached to each quantity of fuel it sells so that the consumer of the fuel could correctly calculate the emissions of the fuel it uses.
The consumer (e.g., Fuel user ) can identify waste such as a freight carrier or airline) could then identify the embedded waste metahne emissions through public view functions of the NFT, such as carbon intensity metrics:
- 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

consumer could also reduce its carbon intensity (CI) by purchasing a certificate from a low CI producer. This would require simultaneously 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 for fuel consumers looking to reduce their emissions footprint to incentivize producers to reduce their carbon intensity.

Figure 3 depicts an ongoing effort by the blockchain carbon accounting team to collect emission data points into a database (orbitDB) using IPFS or Fabric. These are connected to Ethereum contracts (NET/C-NFT) using a ChainLink oracle service or DAO.
The next step will involve building tools to pull in different data sources to support independent auditing and verification (MRV cycle):
- company voluntary reports/ ERP sensors (gas flaring)
- independent tracking service focusing on Flaring Monitor

The GHG Protocol provides a free tool to help measures cross-sector value-chain impacts. It provides inputs typically used in LCA practices, which may only provide historic/aggregate data from several years ago. It is more focused on providing measures for individual organizations as opposed to connecting reporting activities. However, according to the Carbon Disclosure Project (CDP), value chain reporting has not been very successful in reducing emissions (Patchell 2018).
Value chain reporting may use the Life Cycle Assessment (LCA) practice, which can be difficult for organizations to implement on their:
- Access the credible metrics restricted by data silos across emission measurement, reporting and verification (MRV) systems
- Rely on historic data based that may be several years old
- Employ of on model estimates that may be subjective and hard to validate
LCA applied to fuel carbon intensity standards have no been very effective in mitigating emissions (Plevin et al 2017).
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 not connecting them.

Our target product is a portal where data from multiple sources of methane emissions could be viewed, and the final methane emissions for a production facility is calculated. Then an oil & gas producer could also:
- registers as an industry dealer of the NET network
- construct a (voluntary) emission profile (C-NFT) for current inventories (using VCT) based on the calculated methane emissions
- connects its C-NFT profile to the waste emission verification system (Figure 3)
- list inventories as digital VCT that can be transferred to other industry/consumer accounts.
